What is a program that gives a computer instructions?

software, instructions that tell a computer what to do. Software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system. The term was coined to differentiate these instructions from hardware—i.e., the physical components of a computer system.

How does a computer interpret binary?

The digits 1 and 0 used in binary reflect the on and off states of a transistor. Each instruction is translated into machine code – simple binary codes that activate the CPU . Programmers write computer code and this is converted by a translator into binary instructions that the processor can execute .

What does a computer use to process bits?

The computer uses electricity, not mechanical parts, for its data processing and storage. Computers do this representation using a binary coding system. Binary and Switches. Binary is a mathematical number system: a way of counting.

What three types of instructions do computer programs need?

A basic computer has three instruction code formats which are:

• Memory – reference instruction.
• Register – reference instruction.
• Input-Output instruction.

What is computer programming simple definition?

Computer programming is the process that professionals use to write code that instructs how a computer, application or software program performs. At its most basic, computer programming is a set of instructions to facilitate specific actions.

Where are the basic instructions of the computer stored?

main memory
The CPU is the heart of the computer. A program is a sequence of instructions stored in main memory.

Why does a computer only understand binary?

Computers don’t understand words or numbers the way humans do. To make sense of complicated data, your computer has to encode it in binary. Binary is a base 2 number system. Base 2 means there are only two digits—1 and 0—which correspond to the on and off states your computer can understand.

How are computer circuits used?

Computer circuits are binary in concept, having only two possible states. They use on-off switches (transistors) that are electrically opened and closed in nanoseconds and picoseconds (billionths and trillionths of a second). A computer’s speed of operation depends on the design of its circuitry.
