The Tandy Color Computer 3 could display all of the modes of the Tandy Color Computer 1 and 2 / TRS-80 Color Computer, except the Semigraphics modes. Taking the place of the graphics and memory hardware of the previous machines is an application-specific integrated circuit called (officially) the Advanced Color Video Chip (ACVC) or ...
An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.
The BBC planned to give away the computer free to every Year 7 (ages 11 and 12) child in Britain starting from October 2015 - around 1 million devices. [ 4 ] [ 20 ] In advance of the roll-out an online simulator was made available to help educators prepare and some teachers were to receive the device in September 2015. [ 3 ]
Computer engineering is a discipline that integrates several fields of electrical engineering and computer science required to develop computer hardware and software. [34] Computer engineers usually have training in electronic engineering (or electrical engineering ), software design , and hardware-software integration, rather than just ...
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
QLogo is an open-source and cross-platform rewrite of UCBLogo with nearly full UCB compatibility that uses hardware-accelerated graphics. Lynx is an online version of Logo developed by Logo Computer Systems Inc. It can run a large number of turtles, supports animation, parallel processes, colour and collision detection.
The storage of computer programs is key to the operation of modern computers and is the connection between computer hardware and software. [7] Even prior to this, in the mid-19th century mathematician George Boole invented Boolean algebra —a system of logic where each proposition is either true or false.
Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).
