Document Summary
Mis (comm 190) class 3 & 4. Mainframes are the first commercial digital computers that were large room sized devices and were used by business and government. Computers that had no display screen or monitor and required users to develop their programs. Programming languages such as basic and os like dos could be used on these microcomputers eventually. Data storage and network capacity also continue to advance too. Electronic components and related gadgetry that input, process, output, and store data according to instructions encoded in computer programs or software. Some examples of input hardware devices are: keyboard, mouse, document scanners, and barcode scanners, monitors, etc. to input data into the device so that the cpu can process it to create outputs. The cpu is a processing device sometimes called the brain of the computer. It selects instructions, processes them, and performance arithmetic and logical comparisons and also even stores results of operations in memory.
