Alfred is a long-time teacher and also computer enthusiast that works with and troubleshoots a wide selection of computing devices.

You are watching: Which of the following is one of the four major functions of a computer

The 4 functions that a computer actually describe the core factors why it to be built. They include:

Data inputData processing.Information output.Data and information storage.


To show the four features of a computer, we can take a look in ~ the an easy steps we all go with to create a LETTER top top the computer.

It starts when the user composes, inputs and also edits set of letters, numbers and also symbols making use of a keyboard. The life data is then processed and viewed real-time via display screen hardware.

Finally, the user may select to print the letter ~ above paper, or much better still send it via electronic mail come designated recipients.

The same data and information deserve to be retained digitally in disk drives and also other media because that future reference.

1. Data Input

Every computer is designed with data input together a an initial function, an task which is completed via input devices.

Data entry is done manually, immediately or both. Manual input is excellent via add-on peripherals choose the keyboard, mouse and also stylus. Input can likewise be completed via vocal dictation applications and also body gestures peripherals choose Kinect and also biometric devices. Elsewhere, data entry is also done using second storage media and also networking interfaces.

Application software offered for this objective will also dictate what data is entered. Word processing software is designed to input basic alphanumerical data, if a photo editing and enhancing application is offered to input and manipulate images.

This data might be gone into into a database, spreadsheet or other develops of a computerized job-related area.

Automated applications and robotics can additionally be supplied to intelligently feed data right into the computer on station or remotely. Together an example, tallying that electoral process can be accomplished remotely and automatically.


2. Data Processing

Data handling is the core function of a computer. Processing involves manipulation of life data into before converting the into systematic information. Usually, data is in life form, and also will thus undergo processing prior to dissemination for user consumption.

The 'brain' the the computer where data is handle is referred to as the microprocessor. The is also commonly well-known as the central processing unit (CPU) or increased processing unit (APU).

The handling chips in modern personal computer devices continue to evolve and also outperform the predecessors. One specific evolution is the mergers of microprocessor and graphics processing unit (GPU) right into what is now recognized as increased processing unit. The merger permits for the integration of an effective graphics processing abilities inside the classic arithmetic and logical computations the the processor.

Besides the microprocessor, the dynamic random accessibility memory (DRAM) and also static random access memory (SRAM) room integral parts of data processing. Data entered via input gadgets is stored temporarily in DRAM, then transferred to SRAM from where the microprocessor manipulates it.

3. Information Output

When life data has been manipulated by the microprocessor, the outcome is meant to be disseminated for valuable purposes. The calculation is hence referred to as information and is advantageous to the computer system user.

Processed data or information can be,

viewed together alphanumeric, photos and video clip via a screen hardwarelistened to as audio papers by usage of a speakerprinted as hard copy calculation onto paperprinted together 3D models

4. Data and also Information Storage

The fourth and equally an extremely important role of a computer is data and also information storage. After ~ sleepless nights of video clip and animation creation and also editing, the user desires to have actually the finished product stored because that future dissemination and added editing.

A computer can store info internally and externally. The hard disk journey (HDD) and/or solid-state disk journey (SSD) are interior storage devices and serve to protect and house every data and information on a computer. In bigger systems, the RAID device is used. Multiple disk drives operate simultaneously come ensure data and also information integrity.

External warehouse is accomplished through accessories that attach externally come the computer. They encompass external drives and also optical disks.

Better tho data and also information have the right to be stored digital in cloud solutions for a fee or for a fee if huge space is required.

Storage truth is a vital phase that deserve to actually recognize the precious of a computer system. In any kind of case, what usage is a computer system without data and information?
