## What is a function answer?

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..

## Why do we use function?

The first reason is reusability. Once a function is defined, it can be used over and over and over again. You can invoke the same function many times in your program, which saves you work. … Another aspect of reusability is that a single function can be used in several different (and separate) programs.

## WHAT IS function and relation?

A function is a special type of relation where every input has a unique output. Definition: A function is a correspondence between two sets (called the domain and the range) such that to each element of the domain, there is assigned exactly one element of the range. Example.

## What is function explain?

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. We can write the statement that f is a function from X to Y using the function notation f:X→Y. …

## What is CPU with diagram?

A CPU is an electronics circuit used in a computer that fetches the input instructions or commands from the memory unit, performs arithmetic and logic operations and stores this processed data back to memory.

## What exactly is a computer?

A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks.

## What are the 5 functions of a computer?

These usually include:Input or inserting data and instructions.Processing.Output or retrieving data or information.Storing data or information/file management.Controlling of devices and functions.

## What is computer block diagram?

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams.

## What are the 5 basic parts of a computer?

5 parts of a computerA motherboard.A Central Processing Unit (CPU)A Graphics Processing Unit (GPU), also known as a video card.Random Access Memory (RAM), also known as volatile memory.Storage: Solid State Drive (SSD) or Hard Disk Drive (HDD)

## How do you create a block diagram?

Block Diagram: Best PracticesIdentify the system. Determine the system to be illustrated. … Create and label the diagram. Add a symbol for each component of the system, connecting them with arrows to indicate flow. … Indicate input and output. … Verify accuracy.

## What are the 4 main functions of a computer?

There are four main equipment functions of a computer system: Input, Processing, Storage and Output.

## What are the main functions of a computer?

There are four primary functions of a computer — input, output, processing, and storage. These functions describe what is meant by the term “manipulate” when used to describe what a computer is.
