Each virtual terminal can be logged in with a different user and it can run its own shell and have its own font settings. The virtual terminal gives the impression that several independent terminals are running concurrently. For example, both the Linux kernel and BSD kernels support virtual terminals - terminals that are logically separate, but which access the same physical keyboard and monitor. The virtual terminalДЄ virtual terminal or virtual console is a program that simulates a physical terminal.

Today, in the software world, 'console' and 'terminal' has become completely synonymous. Among its major upgrades was a number of international character sets, as well as the ability to define new character sets, and a much lighter keyboard.

The 200 series replaced the VT100 series. The VT240 added monochrome vector graphics support to the base model, while the VT241 did the same in color. The VT220 is an ANSI standard video terminal introduced by Digital Equipment Corporation (DEC) in November 1983. This led to rapid uptake of the ANSI standard, becoming the de facto standard for terminal emulators. It was one of the first terminals to support ANSI escape codes for cursor control and other tasks, and added a number of extended codes for special features like controlling the status lights on the keyboard.

The VT100 is a video terminal, introduced in August 1978 by Digital Equipment Corporation (DEC). The video terminal provides a way for the kernel and other processes to send text output on the monitor to the user, and to receive text input from the user via the keyboard. Both the 'console' and the 'terminal' now referred to the physical video terminal that had replaced both the teleprinter and the old control console. Later, as computers became much smaller, it was possible to integrate multiple components into one single unit, with both a video monitor and a keyboard put together inside it, and the 'console' now became more or less synonymous to the 'terminal'. In the picture below Ken Thompson (sitting) and Dennis Ritchie (standing) is using a 33 ASR teleprinter connected to a PDP-11, the picture is from 1972.

If you're interested I can highly recommend that you take a look at Charles Baetsen's Hobby Page as he has a wealth of information about the Teletype 33 ASR in the form of both user manuals, installations manuals and videos. The ASR 33 had a built-in punched tape reader and tape punch which allowed the user to save programs.ДЄ Teletype Model 33 ASR teleprinter, usable as a terminal. The ASR stands for Automatic Send and Receive. It was introduced in 1963 as an electro-mechanical teleprinter and it was one of the most popular terminals in the communications industry. In the picture below is a Teletype 33 ASR Teleprinter. Some models could also be used to create punched tape for data storage (either from typed input or from data received from a remote source) and to read back such tape for local printing or transmission. When the computer replied, you would see the typewriter print on the paper. When you typed on it, you would see the text on a piece of paper and that text would be send to the computer. Rather than a monitor you would have a literal typewriter in front of you. The teleprinter or TTY was the first kind of terminal.

You will sometimes hear the description 'a dumb terminal' when referring to a text-based environment where the computer is just taking input and showing text while the real work happens at the other end, typically in a mainframe. The word terminal comes from the Latin 'terminus', meaning 'an end, a limit, boundary line', indicating that it's the terminating end or 'terminal' end of a communications process. In the pictures below is a 'UNIVAC 1' control console and a 'UNIVAC 2' control console. The image below is a Univac 9400 system from 1967 consisting of several cabinets. one cabinet for the CPU, one or more cabinets for tape drives, one cabinet for each disk drive, one cabinet for a punched card reader and one cabinet for a high speed printer. And I will also give my advice to new users on Linux or BSD regarding the choice of terminal emulator and shell.Д®arly computers where huge machines that consisted of multiple cabinets, e.g. So without further ado we will now stroll down memory lane and take a quick look at the origins of the Unix terminal and shell.

I have decided to rewrite these notes in order to share them here on my website. The other day, as I was going through some of my old notes, I stumbled upon something I had written about the console, the terminal and the shell on Unix-like operating systems. | about | faq | hire me | contact | rss The terminal, the console and the shell - what are they?
