IIn education, the student uses the computer to perform three
functions: logic comparisons, arithmetic operations, storage, and
retrieval. TThe computer accomplishes these functions at high
speed, storing huge amounts of data in a binary format. TThe
central processing unit (CPU), controls what is happening.
Arithmetic logic unit (ALU) performs arithmetic operations. Primary
memory, ROM and RAM, store all data and instructions necessary for
operations. TThe operating system, is the control program that
handles the transfer of data, and makes possible to enters and runs
programs. This Chapter has explored the functions of the major
input, output, and input/output devices; and the criteria for
hardware selection.
