What is a Computer?

Definition:

“A computer is a programmable machine.” The two principal characteristics of a computer are:

• It responds to a specific set of instructions in a well-defined manner

• It can execute a prerecorded list of instructions (a program).” http://www.webopedia.com



What is a Computer?

Definitions:

• “A computer is a programmable machine. The two principal

characteristics of a computer are: 1) It responds to a specific set of instructions in a well-defined manner 2) It can execute a prerecorded list of instructions (a program).” http://www.webopedia.com

• “A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.” http://en.wikipedia.org/wiki/Computer



What is a Program?

Algorithm:

An effective method expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite[number of well-defined successive states, eventually producing "output“ http://en.wikipedia.org/wiki/Algorithm#Informal_definition

Procedure that produces the answer to a question or the solution to a problem in a finite number of steps. http://www.merriam-webster.com/dictionary/algorithm
