Millennium

A millennium (plural millennia) is a period of time equal to 1000 years. It derives from the Latin mille, thousand, and annus, year. It is often, but not always, related to a particular dating system.

Sometimes, it is used specifically for periods of a thousand years that begin at the starting point (initial reference point) of the calendar in consideration (typically the year "1"), or in later years that are whole number multiples of a thousand years after it. The term can also refer to an interval of time beginning on any date. Frequently in the latter case (and sometimes also in the former) it may have religious or theological implications (see millenarianism). Sometimes in use, such an interval called a "millennium" might be interpreted less precisely, i.e., not always being exactly 1000 years long. It could be, for example, 1050, etc.

Counting years

There are two methods of counting years, current years (the count begins at the epoch) and elapsed years (the count is of completed years since the epoch). This latter method is used in India.

Yu-Gi-Oh!

Yu-Gi-Oh! (遊☆戯☆王, Yū-Gi-Ō!, lit. "Game King") is a Japanese manga series about gaming written and illustrated by Kazuki Takahashi. It was serialized in Shueisha's Weekly Shōnen Jump magazine between September 30, 1996 and March 8, 2004. The plot follows the story of a boy named Yugi Mutou, who solves the ancient Millennium Puzzle, and awakens a gambling alter-ego within his body that solves his conflicts using various games.

Two anime adaptations were produced; one by Toei Animation, which aired from April 4, 1998 to October 10, 1998, and another produced by NAS and animated by Studio Gallop titled Yu-Gi-Oh! Duel Monsters, which aired between April 2000 and September 2004. The manga series has spawned a franchise that includes multiple spinoff manga and anime series, a trading card game, and numerous video games. Most of the incarnations of the franchise involve the fictional trading card game known as Duel Monsters, where each player uses cards to "duel" each other in a mock battle of fantasy "monsters", which forms the basis for the real life Yu-Gi-Oh! Trading Card Game.

Environment variable

Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer.

They are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process.

They were introduced in their modern form in 1979 with Version 7 Unix, so are included in all Unix operating system flavors and variants from that point onward including Linux and OS X. From PC DOS 2.0 in 1982, all succeeding Microsoft operating systems including Microsoft Windows, and OS/2 also have included them as a feature, although with somewhat different syntax, usage and standard variable names.

Details

In all Unix and Unix-like systems, each process has its own separate set of environment variables. By default, when a process is created, it inherits a duplicate environment of its parent process, except for explicit changes made by the parent when it creates the child. At the API level, these changes must be done between running fork and exec. Alternatively, from command shells such as bash, a user can change environment variables for a particular command invocation by indirectly invoking it via env or using the ENVIRONMENT_VARIABLE=VALUE <command> notation. All Unix operating system flavors, DOS, and Windows have environment variables; however, they do not all use the same variable names. A running program can access the values of environment variables for configuration purposes.

CLS (command)

In computing, CLS (for clear screen) is a command used by the command line interpreters COMMAND.COM and CMD.EXE on DOS, OS/2 and Microsoft Windows operating systems to clear the screen or console window of commands and any output generated by them. It does not clear the user's history of commands, however. The command is also available in the DEC RT-11 operating system. In other environments, such as Linux and Unix, the same functionality is provided by the clear command.

While the ultimate origins of using the three-character string CLS as the command to clear the screen likely predate Microsoft's use, this command was present before its MS-DOS usage, in the embedded ROM BASIC dialects Microsoft wrote for early 8-bit microcomputers (such as TRS-80 Color BASIC), where it served the same purpose. The MS-DOS dialects of BASIC written by Microsoft, BASICA and GW-BASIC, also have the CLS command as a BASIC keyword - as do various non-Microsoft implementations of BASIC such as BBC BASIC found on the BBC Micro computers. The CLS command is also present in BASIC versions for Microsoft Windows, however this generally clears text printed on the form, rather than the whole screen or controls on the form.

CONFIG.SYS

CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems. It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system during boot. CONFIG.SYS was introduced with DOS 2.0.

Usage

The directives in this file configure DOS for use with devices and applications in the system. The CONFIG.SYS directives also set up the memory managers in the system. After processing the CONFIG.SYS file, DOS proceeds to load and execute the command shell specified in the SHELL line of CONFIG.SYS, or COMMAND.COM if there is no such line. The command shell in turn is responsible for processing the AUTOEXEC.BAT file.

CONFIG.SYS is composed mostly of name=value directives which look like variable assignments. In fact, these will either define some tunable parameters often resulting in reservation of memory, or load files, mostly device drivers and TSRs, into memory.

In DOS, CONFIG.SYS is located in the root directory of the drive from which the system was booted.
