67-665: A CTO is very similar to a chief information officer (CIO). CTOs will make decisions for the overarching technology infrastructure that closely align with the organization's goals, while CIOs work alongside the organization's information technology ("IT") staff members to perform everyday operations. The attributes of the roles a CTO holds vary from one company to another, mainly depending on their organizational structure. After World War II , large corporations established research laboratories at locations separate from their headquarters. The corporation's goals were to hire scientists and offer them facilities to conduct research on behalf of

134-636: A Master of Science in Management degree. More recently, CIOs' leadership capabilities, business acumen, and strategic perspectives have taken precedence over technical skills. It is now quite common for CIOs to be appointed from the business side of the organization, especially if they have project management skills. Despite the strategic nature of the role, a 2017 survey, conducted by Logicalis , of 890 CIOs across 23 countries found that 62% of CIOs spend 60% or more of their time on day to day IT activities. In 2012, Gartner Executive Programs conducted

201-618: A business context, the Information Technology Association of America has defined information technology as "the study, design, development, application, implementation, support, or management of computer-based information systems". The responsibilities of those working in the field include network administration, software development and installation, and the planning and management of an organization's technology life cycle, by which hardware and software are maintained, upgraded, and replaced. Information services

268-542: A business leader. The CIO makes executive decisions regarding matters such as the purchase of IT equipment from suppliers or the creation of new IT systems. Also as a business leader, the CIO is responsible for leading and directing the workforce of their specific organization. A CIO is typically "required to have strong organizational skills." This is particularly relevant for the chief information officer of an organization who must balance roles and responsibilities in order to gain

335-404: A business. However, regulations such as GDPR have also been advantageous to CIOs, enabling them to have the budget and authority in the organization to make significant changes to the way information is managed. Sabah Khan-Carter of Rupert Murdoch's News Corp described GDPR as "a really big opportunity for most organizations". Many candidates have a Master of Business Administration degree or

402-517: A competitive advantage, whilst keeping the best interests of the organization's employees in mind. CIOs also have the responsibility of recruiting, so it is important that they work proactively to source and nurture the best employees possible. CIOs are required to map out both the ICT strategy and ICT policy of an organization. The ICT strategy covers future-proofing, procurement, and the external and internal standards laid out by an organization. Similarly,

469-542: A complete computing machine. During the Second World War , Colossus developed the first electronic digital computer to decrypt German messages. Although it was programmable , it was not general-purpose, being designed to perform only a single task. It also lacked the ability to store its program in memory; programming was carried out using plugs and switches to alter the internal wiring. The first recognizably modern electronic digital stored-program computer

536-475: A component of their 305 RAMAC computer system. Most digital data today is still stored magnetically on hard disks, or optically on media such as CD-ROMs . Until 2002 most information was stored on analog devices , but that year digital storage capacity exceeded analog for the first time. As of 2007 , almost 94% of the data stored worldwide was held digitally: 52% on hard disks, 28% on optical devices, and 11% on digital magnetic tape. It has been estimated that

603-491: A global CIO survey and received responses from 2,053 CIOs from 41 countries and 36 industries. Gartner reported that survey results indicated that the top ten technology priorities for CIOs for 2013 were analytics and business intelligence , mobile technologies , cloud computing , collaboration technologies , legacy modernization , IT management , customer relationship management , virtualization , security , and enterprise resource planning . CIO magazine's "State of

670-450: A more efficient manner are usually seen as "just the cost of doing business." IT departments are allocated funds by senior leadership and must attempt to achieve the desired deliverables while staying within that budget. Government and the private sector might have different funding mechanisms, but the principles are more-or-less the same. This is an often overlooked reason for the rapid interest in automation and Artificial Intelligence , but

737-473: A particular letter; possible delays in message delivery (up to several days); limits on the size of one message and on the total size of messages in the mailbox (personal for users). A software and hardware complex with a web interface that provides the ability to search for information on the Internet. A search engine usually means a site that hosts the interface (front-end) of the system. The software part of

804-405: A search engine is a search engine (search engine) — a set of programs that provides the functionality of a search engine and is usually a trade secret of the search engine developer company. Most search engines look for information on World Wide Web sites, but there are also systems that can look for files on FTP servers, items in online stores, and information on Usenet newsgroups. Improving search

871-464: A technology now obsolete. Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay-line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line. The first random-access digital storage device was the Williams tube , which was based on a standard cathode ray tube . However,

938-439: Is a job title commonly given to the most senior executive in an enterprise who works with information technology and computer systems, in order to support enterprise goals. Normally, the CIO reports directly to the chief executive officer , but may also report to the chief operating officer or chief financial officer . In military organizations, the CIO reports to the commanding officer . The role of chief information officer

1005-487: Is a term somewhat loosely applied to a variety of IT-related services offered by commercial companies, as well as data brokers . The field of information ethics was established by mathematician Norbert Wiener in the 1940s. Some of the ethical issues associated with the use of information technology include: Research suggests that IT projects in business and public administration can easily become significant in scale. Work conducted by McKinsey in collaboration with

1072-433: Is also worth noting that from a business perspective, Information technology departments are a " cost center " the majority of the time. A cost center is a department or staff which incurs expenses, or "costs", within a company rather than generating profits or revenue streams. Modern businesses rely heavily on technology for their day-to-day operations, so the expenses delegated to cover technology that facilitates business in

1139-494: Is as much about anticipating technology and usage trends in the market place as it is about ensuring that the business navigates these trends with expert guidance and strategic planning aligned to the corporate strategy. The roles of chief information officer, chief digital officer and chief technology officer are often mixed up. It has been stated that CTOs are concerned with technology itself, often customer-facing, whereas CIOs are much more concerned with its applications within

1206-566: Is commonly held in relational databases to take advantage of their "robust implementation verified by years of both theoretical and practical effort." As an evolution of the Standard Generalized Markup Language (SGML), XML's text-based structure offers the advantage of being both machine- and human-readable . Data transmission has three aspects: transmission, propagation, and reception. It can be broadly categorized as broadcasting , in which information

1273-768: Is generally an information system , a communications system , or, more specifically speaking, a computer system — including all hardware , software , and peripheral equipment — operated by a limited group of IT users, and an IT project usually refers to the commissioning and implementation of an IT system. IT systems play a vital role in facilitating efficient data management, enhancing communication networks, and supporting organizational processes across various industries. Successful IT projects require meticulous planning, seamless integration, and ongoing maintenance to ensure optimal functionality and alignment with organizational objectives. Although humans have been storing, retrieving, manipulating, and communicating information since

1340-460: Is not uncommon for CIOs to be recognized and awarded annually, particularly in the technology space. These awards are commonly dictated by the significance of their contribution to the industry and generally occur in local markets only. Awards are generally judged by industry peers, or senior qualified executives such as the chief executive officer , chief operating officer or chief financial officer . Generally, awards recognize substantial impact to

1407-507: Is one of the priorities of the modern Internet (see the Deep Web article about the main problems in the work of search engines). Companies in the information technology field are often discussed as a group as the "tech sector" or the "tech industry." These titles can be misleading at times and should not be mistaken for "tech companies;" which are generally large scale, for-profit corporations that sell consumer technology and software. It

1474-424: Is still widely deployed more than 50 years later. IMS stores data hierarchically , but in the 1970s Ted Codd proposed an alternative relational storage model based on set theory and predicate logic and the familiar concepts of tables, rows, and columns. In 1981, the first commercially available relational database management system (RDBMS) was released by Oracle . All DMS consist of components, they allow

1541-417: Is transmitted unidirectionally downstream, or telecommunications , with bidirectional upstream and downstream channels. XML has been increasingly employed as a means of data interchange since the early 2000s, particularly for machine-oriented interactions such as those involved in web-oriented protocols such as SOAP , describing "data-in-transit rather than... data-at-rest". Hilbert and Lopez identify

1608-454: The Internet , which was equivalent to 51 million households. Along with the Internet, new types of technology were also being introduced across the globe, which has improved efficiency and made things easier across the globe. Along with technology revolutionizing society, millions of processes could be done in seconds. Innovations in communication were also crucial as people began to rely on

1675-599: The chief information officer (CIO) and is primarily concerned with long-term and "big picture" issues (while still having deep technical knowledge of the relevant field). In technology-focused organizations, the CIO and CTO positions can be at the same level, with the CIO focused on the information technology and the CTO focused on the core company and other supporting technologies. Depending on company structure and hierarchy, there may also be positions such as R&D manager, director of R&D and vice president of engineering whom

1742-432: The 16th century, and it was not until 1645 that the first mechanical calculator capable of performing the four basic arithmetical operations was developed. Electronic computers , using either relays or valves , began to appear in the early 1940s. The electromechanical Zuse Z3 , completed in 1941, was the world's first programmable computer, and by modern standards one of the first machines that could be considered

1809-410: The 1980s, the role of these research directors changed substantially. Since technology was becoming a fundamental part of the development for most products and services, companies needed an operational executive who could understand the product's technical side and provide advice on ways to improve and develop. This all led to the creation of the position of Chief Technology Officer by large companies in

1876-432: The CIO 2008" survey asked 558 IT leaders whom they report to, and the results were: CEO (41%), CFO (23%), COO (16%), corporate CIO (7%) and other (13%). Typically, the CIO is involved with driving the analysis and re-engineering of existing business processes, identifying and developing the capability to use new tools, reshaping the enterprise's physical infrastructure and network access, and identifying and exploiting

1943-585: The CIO must develop the ICT policy, which details how ICT is utilized and applied. Both are needed for the protection of the organization in the short and long term and the process of strategizing for the future. Paul Burfitt, former CIO of AstraZeneca , also outlines the role of the CIO in IT governance, which he refers to as the "clarifying [of] accountability and the role of committees". In recent years, CIOs have become more closely involved in customer-facing products. With

2010-445: The CIO role has changed is an increasing focus on service management. As SaaS , IaaS , BPO and other flexible delivery techniques are brought into organizations the CIO usually manages these 3rd party services. In essence, a CIO in the modern organization needs business skills and the ability to relate to the organization as a whole, as opposed to being a technological expert with limited functional business expertise. The CIO position

2077-592: The CTO interacts with or oversees. The CTO also needs a working familiarity with regulatory (e.g. U.S. Food and Drug Administration , Environmental Protection Agency , Consumer Product Safety Commission , as applicable) and intellectual property (IP) issues (e.g. patents , trade secrets , license contracts), and an ability to interface with legal counsel to incorporate these considerations into strategic planning and inter-company negotiations. In many older industries (whose existence may predate IT automation) such as manufacturing, shipping or banking, an executive role of

2144-506: The CTO would often arise out of the process of automating existing activities; in these cases, any CTO-like role would only emerge if and when efforts would be made to develop truly novel technologies (either for facilitating internal operations or for enhancing products/services being provided), perhaps through " intrapreneuring ". Chief information officer Chief information officer ( CIO ), chief digital information officer ( CDIO ) or information technology ( IT ) director ,

2211-410: The Internet alone while e-commerce a decade later resulted in $ 289 billion in sales. And as computers are rapidly becoming more sophisticated by the day, they are becoming more used as people are becoming more reliant on them during the twenty-first century. Early electronic computers such as Colossus made use of punched tape , a long strip of paper on which data was represented by a series of holes,

2278-417: The ability to transfer both plain text and formatted, as well as arbitrary files; independence of servers (in the general case, they address each other directly); sufficiently high reliability of message delivery; ease of use by humans and programs. Disadvantages of e-mail: the presence of such a phenomenon as spam (massive advertising and viral mailings); the theoretical impossibility of guaranteed delivery of

2345-527: The appearance of the term in 1990 contained within documents for the International Organization for Standardization (ISO). Innovations in technology have already revolutionized the world by the twenty-first century as people were able to access different online services. This has changed the workforce drastically as thirty percent of U.S. workers were already in careers in this profession. 136.9 million people were personally connected to

2412-567: The application of statistical and mathematical methods to decision-making , and the simulation of higher-order thinking through computer programs. The term is commonly used as a synonym for computers and computer networks , but it also encompasses other information distribution technologies such as television and telephones . Several products or services within an economy are associated with information technology, including computer hardware , software , electronics, semiconductors, internet , telecom equipment , and e-commerce . Based on

2479-422: The ascent of the IT industry, but has since become prevalent in technology-based industries of all types – including computer-based technologies (such as game developer , e-commerce , and social networking service ) and other/non-computer-focused technology (such as biotech / pharma , defense , and automotive ). In non-technical organizations as a corporate officer position, the CTO typically reports directly to

2546-456: The business and how they can be managed. More specifically, CIOs oversee a business's IT systems and functions, create and deliver strategies and policies, and focus on internal customers. In contrast to this, CTOs focus on the external customers to the organization and how technology can make the company more profitable. The traditional definition of CTOs focused on using technology as an external competitive advantage now includes CDOs who use

2613-550: The business needs, user needs, and the information and communication technology (ICT) used in the work. In recent years it has become increasingly understood that knowledge limited to just business or just IT is not sufficient for success in this role. Instead, CIOs need both kinds of knowledge to manage IT resources and to manage and plan " ICT , including policy and practice development, planning, budgeting, resourcing and training." Also, CIOs are playing an increasingly important role in helping to control costs and increase profits via

2680-444: The company without the burdens of day-to-day office work. This is where the idea of a CTO focusing on the overarching technology infrastructures originates. At that time, the director of the laboratory was a corporate vice president who did not participate in the company's corporate decisions. Instead, the technical director was the individual responsible for attracting new scientists, to do research, and to develop products . In

2747-464: The computer to communicate through telephone lines and cable. The introduction of the email was considered revolutionary as "companies in one part of the world could communicate by e-mail with suppliers and buyers in another part of the world..." Not only personally, computers and technology have also revolutionized the marketing industry, resulting in more buyers of their products. During the year of 2002, Americans exceeded $ 28 billion in goods just over

2814-419: The constant pressure to do more with less is opening the door for automation to take control of at least some minor operations in large companies. Many companies now have IT departments for managing the computers , networks, and other technical areas of their businesses. Companies have also sought to integrate IT with business outcomes and decision-making through a BizOps or business operations department. In

2881-431: The data they store to be accessed simultaneously by many users while maintaining its integrity. All databases are common in one point that the structure of the data they contain is defined and stored separately from the data itself, in a database schema . In recent years, the extensible markup language (XML) has become a popular format for data representation. Although XML data can be stored in normal file systems , it

2948-504: The earliest writing systems were developed, the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review ; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for processing,

3015-566: The emergence of information and communications technology (ICT). By the year of 1984, according to the National Westminster Bank Quarterly Review , the term information technology had been redefined as "The development of cable television was made possible by the convergence of telecommunications and computing technology (…generally known in Britain as information technology)." We then begin to see

3082-521: The enterprise's knowledge resources. Many CIOs head the enterprise's efforts to integrate the Internet into both its long-term strategy and its immediate business plans. CIOs are often tasked with either driving or heading up crucial IT projects that are essential to the strategic and operational objectives of an organization. A good example of this would be the implementation of an enterprise resource planning (ERP) system, which typically has wide-ranging implications for most organizations. Another way that

3149-404: The exponential pace of technological change (a kind of Moore's law ): machines' application-specific capacity to compute information per capita roughly doubled every 14 months between 1986 and 2007; the per capita capacity of the world's general-purpose computers doubled every 18 months during the same two decades; the global telecommunication capacity per capita doubled every 34 months;

3216-455: The field of data mining  — "the process of discovering interesting patterns and knowledge from large amounts of data"  — emerged in the late 1980s. The technology and services it provides for sending and receiving electronic messages (called "letters" or "electronic letters") over a distributed (including global) computer network. In terms of the composition of elements and the principle of operation, electronic mail practically repeats

3283-455: The first planar silicon dioxide transistors by Frosch and Derick in 1957, the MOSFET demonstration by a Bell Labs team. the planar process by Jean Hoerni in 1959, and the microprocessor invented by Ted Hoff , Federico Faggin , Masatoshi Shima , and Stanley Mazor at Intel in 1971. These important inventions led to the development of the personal computer (PC) in the 1970s, and

3350-501: The first transistorized computer developed at the University of Manchester and operational by November 1953, consumed only 150 watts in its final version. Several other breakthroughs in semiconductor technology include the integrated circuit (IC) invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor in 1959, silicon dioxide surface passivation by Carl Frosch and Lincoln Derick in 1955,

3417-488: The information stored in it and delay-line memory was volatile in the fact that it had to be continuously refreshed, and thus was lost once power was removed. The earliest form of non-volatile computer storage was the magnetic drum , invented in 1932 and used in the Ferranti Mark 1 , the world's first commercially available general-purpose electronic computer. IBM introduced the first hard disk drive in 1956, as

SECTION 50

3484-538: The introduction of computer science-related courses in K-12 education . Ideas of computer science were first mentioned before the 1950s under the Massachusetts Institute of Technology (MIT) and Harvard University , where they had discussed and began thinking of computer circuits and numerical calculations. As time went on, the field of information technology and computer science became more complex and

3551-480: The late 1980s with the growth of the information technology industry and computer (internet) companies. A CTO "examines the short and long term needs of an organization, and utilizes capital to make investments designed to help the organization reach its objectives... [the CTO] is the highest technology executive position within a company and leads the technology or engineering department". The role became prominent with

3618-734: The local technology market. In Australia , the top 50 CIOs are recognized annually under the CIO50 banner. In the United States of America , United Kingdom and New Zealand CIOs are recognized under the CIO100 banner. Information technology Information technology ( IT ) is a set of related fields that encompass computer systems, software , programming languages , and data and information processing, and storage. IT forms part of information and communications technology (ICT). An information technology system ( IT system )

3685-400: The necessary combination of skills in the marketplace, and may look to train existing staff to mitigate skill shortages. CIOs are needed to bridge the gap between IT and non-IT professional roles to support effective working relationships. The chief information officer of an organization is responsible for several business functions. First and most importantly, the CIO must fulfill the role of

3752-665: The power of modern technologies, online design and big data to digitize a business. CIO Councils bring together a number of CIOs from different organizations which aim to work together, for example across healthcare or across government. Examples include the UK public sector's CIO Council, the London CIO Council for the healthcare sector, and the Chief Information Officers Council in the USA. It

3819-531: The rising awareness in organizations that their customers are expecting digital services as part of their relationship with an organization, CIOs have been tasked with more product-oriented responsibilities. The CIO faces a rather high risk of error and failures, as a result of the challenging nature of the role, along with a large number of responsibilities – such as the provision of finance, recruitment of professionals, establishing data protection and development of policy and strategy. The CIO of U.S company Target

3886-503: The storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical (3000 BC — 1450 AD), mechanical (1450 — 1840), electromechanical (1840 — 1940), and electronic (1940 to present). Information technology is a branch of computer science , defined as the study of procedures, structures, and the processing of various types of data. As this field continues to evolve globally, its priority and importance have grown, leading to

3953-417: The system of regular (paper) mail, borrowing both terms (mail, letter, envelope, attachment, box, delivery, and others) and characteristic features — ease of use, message transmission delays, sufficient reliability and at the same time no guarantee of delivery. The advantages of e-mail are: easily perceived and remembered by a person addresses of the form user_name@domain_name (for example, somebody@example.com);

4020-540: The use of ICT, and to limit potential organizational damage by setting up appropriate IT controls and planning for IT recovery from possible disasters. These objectives also demand a combination of personal skills. Computer Weekly magazine highlights that "53% of IT leaders report a shortage of [IT managers] with a high-level of personal skills, such as communication and leadership" in the workplace. Because information technologies and digital tools evolve so quickly, organizations are sometimes challenged to find staff with

4087-405: The world's storage capacity per capita required roughly 40 months to double (every 3 years); and per capita broadcast information has doubled every 12.3 years. Massive amounts of data are stored worldwide every day, but unless it can be analyzed and presented effectively it essentially resides in what have been called data tombs: "data archives that are seldom visited". To address that issue,

4154-403: The worldwide capacity to store information on electronic devices grew from less than 3  exabytes in 1986 to 295 exabytes in 2007, doubling roughly every 3 years. Database Management Systems (DMS) emerged in the 1960s to address the problem of storing and retrieving large amounts of data accurately and quickly. An early such system was IBM 's Information Management System (IMS), which

4221-503: Was able to handle the processing of more data. Scholarly articles began to be published from different organizations. Looking at early computing, Alan Turing , J. Presper Eckert , and John Mauchly were considered some of the major pioneers of computer technology in the mid-1900s. Giving them such credit for their developments, most of their efforts were focused on designing the first digital computer. Along with that, topics such as artificial intelligence began to be brought up as Turing

4288-496: Was beginning to question such technology of the time period. Devices have been used to aid computation for thousands of years, probably initially in the form of a tally stick . The Antikythera mechanism , dating from about the beginning of the first century BC, is generally considered the earliest known mechanical analog computer , and the earliest known geared mechanism. Comparable geared devices did not emerge in Europe until

4355-546: Was first defined in 1981 by William R. Synnott, former senior vice president of the Bank of Boston, and William H. Gruber, a former professor at the Massachusetts Institute of Technology Sloan School of Management. A CIO will sometimes serve as a member of the board of directors . CIOs and CDIOs play an important role in businesses that use technology and data because they provide a critical interface between

4422-552: Was forced into resignation in 2014 after the theft of 40 million credit card details and 70 million customer details by hackers. CIOs that are knowledgeable about their industry are able to adapt and thereby reduce their chances of error. With the introduction of legislation such as the General Data Protection Regulation (GDPR), CIOs have now become increasingly focused on how their role is regulated and can lead to financial and reputational damage to

4489-468: Was the Manchester Baby , which ran its first program on 21 June 1948. The development of transistors in the late 1940s at Bell Laboratories allowed a new generation of computers to be designed with greatly reduced power consumption. The first commercially available stored-program computer, the Ferranti Mark I , contained 4050 valves and had a power consumption of 25 kilowatts. By comparison,
