Taking data and instructions from a user, processing the data as per instructions, and displaying or storing the processed data, are the four major functions of a computer.

What is main function of computer?
At a fundamental level, computers operate through these four functions: input, output, processing, and storage.
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 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 function in computer in short answer?
A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing.Different programming languages name them differently, for example, functions, methods, sub-routines, procedures, etc.
What are the 10 functions of a computer?
Functions of Computer
- Input Function.
- Processing Data.
- Storing the Data.
- Output Function.
- Conclusion.
What is function in computer with example?
A function is a group of instructions, also known as a named procedure, used by programming languages to return a single result or a set of results.For example, in the excel formula “=SUM(A1:A10),” a function that adds all the numbers in the range of cells specified in the formula.
What is function in computer and its types?
There are four different patterns to define a function − Functions with no argument and no return value. Functions with no argument but a return value. Functions with argument but no return value. Functions with argument and a return value.
What are different type of functions?
List of Types of Functions

What are basic functions?
The basic polynomial functions are: f(x)=c, f(x)=x, f(x)=x2, and f(x)=x3. The basic nonpolynomial functions are: f(x)=|x|, f(x)=√x, and f(x)=1x. A function whose definition changes depending on the value in the domain is called a piecewise function.
What are functions used for?
Because functions describe relationships between quantities, they are frequently used in modeling. Sometimes functions are defined by a recursive process, which can be displayed effectively using a spreadsheet or other technology.
What is function in computer class 9?
A computer has four functions:
Accepts data Input. Processes data Processing. Produces output Output.
What is function in computer class 12?
A function is a group of statements that is executed when it is called from some point of the program. It’s a divide and conquer approach. 6. TYPES OF FUNCTIONS.
What are some examples of a function?
“… each element…” means that every element in X is related to some element in Y. We say that the function covers X (relates every element of it). (But some elements of Y might not be related to at all, which is fine.)
Example: The relationship x → x. 2.
X: x | Y: x2 |
---|---|
3 | 9 |
1 | 1 |
0 | 0 |

What are the 4 types of functions?
The various types of functions are as follows:
- Many to one function.
- One to one function.
- Onto function.
- One and onto function.
- Constant function.
- Identity function.
- Quadratic function.
- Polynomial function.
What are the 12 types of functions?
Terms in this set (12)

- Exponential. f(x)=e^x. D: -∞,∞ R: 0,∞
- Sine. f(x)=SINx. D: -∞,∞ R: -1,1. Odd.
- Greatest Integer. f(x)= [[x]] D: -∞,∞ R: {All Integers} Neither.
- Absolute Value. f(x)= I x I. D: -∞,∞ R: 0,∞
- Linear. f(x)=x. Odd.
- Cubic. f(x)=x^3. Odd.
How do you find a function?
Let f : A —-> B be a function. There exists even a single element in B having no pre-image in A, then f is said to be an into function. The figure given below represents a one-one function.
What are the 8 types of functions?
The eight types are linear, power, quadratic, polynomial, rational, exponential, logarithmic, and sinusoidal.
