The IBM PS/2 Note and PS/note are a series of notebooks from the PS/2 line by IBM . It was announced in March 1992, half a year prior to the release of the first ThinkPad , the IBM ThinkPad 700 . The series was discontinued in 1994.
16-534: After the departure of Bob Lawten from IBM, the team at IBM had little development direction after the IBM PS/2 L40 SX . James Cannavino pushed for the new notebook series, which fell behind schedule. The N45 SL, N51 SX and N51 SLC were announced on the same day as the IBM PS/2 (color laptop) CL57 SX . During this time there was a distinction between notebooks and laptops , where the former are A4 sized and
32-460: A 1.44MB floppy, expansion ports and a 40MB or 80MB HDD, and weighs 5.5 lb (2.5 kg). The PS/2 Model N51 SX (or PS/2 Note N51 SX ) was a low-end mainstream notebook, which contained a slower version of the typical 386SX found in other notebooks. The N51 SX was delayed for months. The PS/2 Model N51 SLC (or PS/2 Note N51 SLC ) was based on IBM their 368SLC . This model has a PS/55 note sibling. Entry-level line. The PS/note N45 SL
48-403: A function is defined in lowercase, it can be called in uppercase, but if a variable is defined in lowercase, it cannot be referred to in uppercase. Nim is case-insensitive and ignores underscores, as long as the first characters match. A text search operation could be case-sensitive or case-insensitive, depending on the system, application, or context. The user can in many cases specify whether
64-475: A search is sensitive to case, e.g. in most text editors, word processors, and Web browsers. A case-insensitive search is more comprehensive, finding "Language" (at the beginning of a sentence), "language", and "LANGUAGE" (in a title in capitals); a case-sensitive search will find the computer language "BASIC" but exclude most of the many unwanted instances of the word. For example, the Google Search engine
80-407: A source code tree for software for Unix-like systems might have both a file named Makefile and a file named makefile in the same directory. In addition, some Mac Installers assume case insensitivity and fail on case-sensitive file systems. The older MS-DOS filesystems FAT12 and FAT16 were case-insensitive and not case-preserving, so that a file whose name is entered as readme.txt or ReadMe.txt
96-583: Is basically case-insensitive, with no option for case-sensitive search. In Oracle SQL, most operations and searches are case-sensitive by default, while in most other DBMSes , SQL searches are case-insensitive by default. Case-insensitive operations are sometimes said to fold case , from the idea of folding the character code table so that upper- and lowercase letters coincide. In filesystems in Unix-like systems, filenames are usually case-sensitive (there can be separate readme.txt and Readme.txt files in
112-613: Is saved as README.TXT. Later, with VFAT in Windows 95 the FAT file systems became case-preserving as an extension of supporting long filenames . Later Windows file systems such as NTFS are internally case-sensitive, and a readme.txt and a Readme.txt can coexist in the same directory. However, for practical purposes filenames behave as case-insensitive as far as users and most software are concerned. This can cause problems for developers or software coming from Unix-like environments, similar to

Retrieved from " https://en.wikipedia.org/wiki/IBM_PS " Case sensitivity In computers, case sensitivity defines whether uppercase and lowercase letters are treated as distinct ( case-sensitive ) or equivalent ( case-insensitive ). For instance, when users interested in learning about dogs search an e-book , "dog" and "Dog" are of
176-633: The latter are larger. The notebooks were modeled after the PS/55 Note which was released by IBM in Japan in April 1991. Mainstream line with 7-row layout only. The PS/2 Model N33 SX (also known as PS/2 note N33 SX ) was the first notebook-sized computer from IBM which was announced in 1991. This model was based on the AT-bus and had between 2 or 6MB RAM. It has a 9.5" 16-greyscale VGA LCD (640x480),

MacOS is somewhat unusual in that, by default, it uses HFS+ and APFS in a case-insensitive (so that there cannot be a readme.txt and a Readme.txt in the same directory) but case-preserving mode (so that a file created as readme.txt is shown as readme.txt and a file created as Readme.txt is shown as Readme.txt) by default. This causes some issues for developers and power users , because most file systems in other Unix-like environments are case-sensitive, and, for example,
208-770: The same significance to them. Thus, they request a case-insensitive search. But when they search an online encyclopedia for information about the United Nations , for example, or something with no ambiguity regarding capitalization and ambiguity between two or more terms cut down by capitalization, they may prefer a case-sensitive search. Case sensitivity may differ depending on the situation: Some programming languages are case-sensitive for their identifiers ( C , C++ , Java , C# , Verilog , Ruby , Python and Swift ). Others are case-insensitive (i.e., not case-sensitive), such as ABAP , Ada , most BASICs (an exception being BBC BASIC ), Common Lisp , Fortran , SQL (for
224-511: The syntax, and for some vendor implementations, e.g. Microsoft SQL Server , the data itself) Pascal , Rexx and ooRexx . There are also languages, such as Haskell , Prolog , and Go , in which the capitalisation of an identifier encodes information about its semantics . Some other programming languages have varying case sensitivity; in PHP , for example, variable names are case-sensitive but function names are not case-sensitive. This means that if
240-527: Was equipped with 80386SL CPU, PS/note N82 was equipped with 80386SX and released in 1992. This line has a 7-row keyboard layout and similar to next-year PS/note 425 model case (but with gray case color and without TrackPoint ). The PS/note 425/425C are identical to the ThinkPad 350/350C . In March 1994, it was reported that IBM would consolidate the PS/note series into the ThinkPad 300 series. In 1994,
256-402: Was priced at $ 2,045 and contains a 25MHz 386SL . It had 2MB RAM and a 80 or 120MB HDD and was equipped with only 6-row keyboard without dedicated navigation block, the similar layout as a low-end ThinkPad 300 laptop. PC Mag considered the display a disappointment, but noted its good design and performance. It was manufactured by Zenith Data Systems . The PS/note 182 and PS/note E82
