What is Slackware Linux?

The Official Release of Slackware Linux by Patrick Volkerding is an advanced Linux operating system, designed with the twin goals of ease of use and stability as top priorities. Including the latest popular software while retaining a sense of tradition, providing simplicity and ease of use alongside flexibility and power, Slackware brings the best of all worlds to the table.

Originally developed by Linus Torvalds in 1991, the UNIX?like Linux operating system now benefits from the contributions of millions of users and developers around the world. Slackware Linux provides new and experienced users alike with a fully-featured system, equipped to serve in any capacity from desktop workstation to machine-room server. Web, ftp, and email servers are ready to go out of the box, as are a wide selection of popular desktop environments. A full range of development tools, editors, and current libraries is included for users who wish to develop or compile additional software.

The Slackware Philosophy

Since its first release in April of 1993, the Slackware Linux Project has aimed at producing the most "UNIX-like" Linux distribution out there. Slackware complies with the published Linux standards, such as the Linux File System Standard. We have always considered simplicity and stability paramount, and as a result Slackware has become one of the most popular, stable, and friendly distributions available.

Slackware Overview

Slackware Linux is a complete 32-bit multitasking "UNIX-like" system.i It's currently based around the 2.4 Linux kernel series and the GNU C Library version 2.3.4 (libc6). It contains an easy to use installation program, extensive online documentation, and a menu-driven package system. A full installation gives you the X Window System, C/C++ development environments, Perl, networking utilities, a mail server, a news server, a web server, an ftp server, the GNU Image Manipulation Program, Netscape Communicator, plus many more programs. Slackware Linux can run on 486 systems all the way up to the latest x86 machines (but uses -mcpu=i686 optimization for best performance on i686-class machines like the P3, P4, and Duron/Athlon). 

Jiffy의 원어는 알 수 없다.

" 짧은 순간 "
> 18세기 영국에서 유래된 것으로 여겨지며. 일반적으로  "매우 짧은 순간"을 의미
> 다양한 분야에서 기본 단위(Unit)를 표현할 때 사용 

[ 과학 분야 ] 

과학 분야에서는 jiffy는 다양한 측정 시간의 단위로 쓰인다. 가장 많이 쓰인다고 여겨지는 것은 10 ms 이다.
특히 물리학에서는 빛이 특정거리(1피트/1센티미터 혹은 양자나 중성자의 지름)를 움직이는데 걸리는 시간을 의미한다.

[ 컴퓨터공학  분야 ]
 
컴퓨터 분야에서 jiffy는 종종 연속된 클럭의 주기를 의미한다.
운영체제 중 유닉스 계열에서 연속된 CPU Tick Count 의 시간을 측정하여 사용한다. 
일반적으로 10ms라고 여겨지지만, CPU의 Hz 변화로 인해 최근에는 CPU 클럭과 OS 특성에 따라 다양한 값을 가질 수 있다. 

[ 전기/전자 분야 ] 
  
전자공학에서는 jiffy는 AC(교류전류)의 한 주기를 완성하는 데 걸리는 시간이며, 미국의 경우 1/60초에 해당한다.
