Dragon Data
Dragon Data Ltd. was a Welsh producer of home computers during the early 1980s. These computers, the Dragon 32 and Dragon 64, strongly resembled the Tandy TRS-80 Color Computer ("CoCo")—both followed a standard Motorola datasheet configuration for the three key components (CPU, SAM and VDG). The machines came in both 32KB and (later) 64KB versions. History The history of Dragon Data in the period 1982–84 was a checkered one. The company was originally set up by toy company Mettoy, and after initial good sales looked to have a bright future. At its high point it entered negotiations with Rexnord's Tano Corporation to form a North American branch. Mettoy then suffered financial difficulties, casting a shadow on the future of Dragon Data before it was spun off as a separate company. However, a number of circumstances (the delay in introducing the 64K model, poor colour support with a maximum of 4 colours displayable in "graphics mode" and only 2 colours in the hi ...

Computer Hardware
Computer hardware includes the physical parts of a computer, such as the computer case, case, central processing unit (CPU), Random-access memory, random access memory (RAM), Computer monitor, monitor, Computer mouse, mouse, Computer keyboard, keyboard, computer data storage, graphics card, sound card, Computer speakers, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is "Hardness, hard" or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or Instruction (computing), instruction. A combination of hardware and software forms a usable computing system, although Digital electronics, other systems exist with only hardware.

Computer Companies Disestablished In 1984
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links bill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
