Quick Answer: What Are The Main Functions Of A Computer?


What are the four main functions of a computer?

All computers carry out four basic functions. These are data input, processing, output and storage.

What are computer functions?

A function is a block of organized, reusable code that is used to perform a single, related action. Different programming languages name them differently, for example, functions, methods, sub-routines, procedures, etc.

What are the five basic functions of a computer?

There are five main hardware components in a computer system: Input, Processing, Storage, Output and Communication devices. Are devices used for entering data or instructions to the central processing unit.

What are the main parts of a computer and their functions?

The hardware components—video card, processor, memory, motherboard and hard drive—are the same for all computer systems.

  • Central Processing Unit (CPU) The CPU is the “brains” of the computer.
  • Random Access Memory (RAM) RAM is variable in a computer.
  • Hard Drive.
  • Video Card.
  • Motherboard.

What are the rules to enter a function in computer?

Answer: Functions are usually represented by a function rule where you express the dependent variable, y, in terms of the independent variable, x. A pair of an input value and its corresponding output value is called an ordered pair and can be written as (a, b). Understand the purpose of the function.

What is the meaning of CPU?

CPU (pronounced as separate letters) is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called a processor, the CPU is the brains of the computer where most calculations take place.

What is a function in algebra?

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Example.

What are the functions?

Definition. A function is a rule which relates the values of one variable quantity to the values of another variable quantity, and does so in such a way that the value of the second variable quantity is uniquely determined by (i.e. is a function of) the value of the first variable quantity.

What do you mean by a function?

A function is a unit of code that is often defined by its role within a greater code structure. Specifically, a function contains a unit of code that works on various inputs, many of which are variables, and produces concrete results involving changes to variable values or actual operations based on the inputs.
