Size doesn’t matter when it comes to a computer; for instance, computers (no matter the
size) can perform the same tasks if given enough storage ability and time. A cell phone is as
much a "computer" as the one that sits on a desk in regard to basic computer operations.
According to eHow (1999-2010), “Basic computer operations are often broken down into four
area but there are six when pertaining to a pseudo code algorithm, which is a detailed, readable
description--not in programming language--of what a computer program must do.”
Basic computer operations
The following are the six basic computer operations:
1. Receive Data - a computer received data input from a particular source (flash
drive, scanners, keyboard, rtc); the verbs GET and READ are utilized in
pseudocode. Read is exercised when the algorithm is to obtain input from the file
whereas GET is used when the algorithm is to receive input from the keyboard,
scanner, or other device. This task can be completed by the input component of
the computer.
2. Output Data – just the opposite of receiving data, a computer can send date or
output data to devices such as printers or modems; this is done when a computer
is prompted to take action. When one sends a file to the printer that is considered
output. This can be done by using the output components.
3. Store Data - a computer can allot a value to a memory location. The following
three instances in which to write pseudocode to assign a value.
