Computer Operations, Solving Problems, and Algorithms

When it comes to computers, size does not matter. Computers big or small can execute similar responsibilities, if the computer is given sufficient storage capability and time. A mobile phone is as much a "computer" as a laptop or desktop computer, in regards to how a basic computer operates. According to eHow (1999-2010), the “necessary computer operations are frequently broken down into four sections, but there are six sections if pertaining to the pseudo code algorithm. The pseudo code algorithm is a comprehensive, understandable description of what a computer program must do in programming language.”

Basic computer operations

The following are the six fundamental computer operations:

1. Receive Data - a computer must be able to receive information from a particular sources such as flash drives, scanners, keyboard, etc); the verbs GET and READ are effective in pseudo code. READ is exercised when the algorithm is to attain input from the file, while GET is used when the algorithm is to obtain input from the keyboard, scanner, or other devices. This job can be accomplished by the input component of the computer.

2. Output Data – is just the reverse of received data. A computer can send data or output data to other devices such as printers or modems When a file is sent to the printer, it is output data. This can be done by using the output components.

3. Store Data - a computer can assign a value to a memory location. There are three examples on how to write pseudo code to allot a value.

 To provide data an earlier value in pseudo code, the verbs SET, or INITIALIZE needs to be used.

 To assign a value as a result of some processing, the symbols ‘=’ or ‘ ’ must be written.

 To save a variable for later use, the verbs STORE, or SAVE needs to be used.
