A computer is an electronic machine that follows given instructions, after processing that instructions show results on the monitor screen. For example, when we type several word sentences in Microsoft Word, we can watch those sentences on the monitor screen after processing.
We know about input devices and output devices. But, there is a central processing device that is the heart of the computer, called the processor.
According to Wikipedia, a computer is a machine that instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers can follow sets of logic operations, called software.
Brief History of computer
According to Computer Hope Blog, the word computer was first used in 1613 in the book The Yong Mans Gleanings by Richard Braithwaite. In 1822, Charles Babbage developed thought and began developing the Difference Engine, which is considered the first automatic computing machine. In 1837, Charles Babbage proposed the first general mechanical computer, the Analytical Engine.
Parts Of Computer
There are three major parts of a computer as input devices, output devices, and a central processing unit.
Input Devices
input devices are that equipment which used to put data and control commands to a processing machine such as a computer. Examples of input devices are keyboard, mouse, scanners, cameras, joysticks, writing pad, touch screen, webcam, fingerprint scanner, and microphone etc. What are the other input devices please comment below? Thanks.
Output Devices
output devices are those computer pieces of equipment which convert your submitted data information on a monitor screen so that a human can read or watch. It can be in the video format, text, graphics, or audio format.
Output devices are available in various forms like monitor screen, printer machine, plotters, speakers, headphones, projector, GPS, sound card, video card, braille reader, and speech synthesis etc.
Central Processing Unit (CPU)
A central processing unit (CPU) is the electronic circuitry within a computer which executes all the given instructions into a result. The instructions, logic, arithmetic make up a computer program.
In other words, we can say that a set of instructions and logics is called a computer program or software. According to Wikipedia, the term central processing unit by the computer industry in 1955.
Nowadays, we have microprocessors on integrated circuits (IC). This IC also contains other components of a computer like memory card, graphics card and other items of the computer. Some computers employ a multi-core processor, which is a single chip or socket containing two or more CPUs called cores.
Motherboard; a printed circuit board containing the principal components of a computer or other device, with connectors for other circuit boards to the slot. It consists of a heart of the computer, the processor, and other hardware like hard drive, RAM card, CD Rom, Floppy, graphic card, gaming card etc.
Now come to the point that what a computer or a laptop does in your life. Believe me, guys, a computer machine is a very incredible electronic machine that does miraculous works in your life. This article will describe all possible entirety that can complete with this machine.
1. Graphics Designing
Graphic designing is a world in itself. Everything in the world is in the shape of a graphic, for example, household items, kitchen items, sky elements, and all the things of the universe are in a proper contour. This all points towards the graphics designing.
Now comes onto the count of creation, in which graphic designing is an art or craft. Graphics professionals envision your ideas to communicate a unique message to their viewers. In graphic designing, there is a creation of a shape with the use of a specific layout and hierarchy of different embodies.
Graphics creation needs logic to make a design. All is possible due to your computer or a laptop. Because, this electronic machine works via software, and apprehend your ideas into a shape or picture. Such pictures are known as logos. So, on this point, we come familiar to the necessity of a computer.

2. Video Editing
Video editing is a cut and pastes and rearranging of several photos to make a video. In the video you have frames, and it depends on the camera quality, usually, the cameras, they can capture with the speed of 30 FPS. Here FPS is the frame per second, a speed unit, on which a camera can capture different scenes.
For video editing, we can use different software as some are available online. And some we can purchase as we have Adobe premiere pro; a video editing software, the most popular one.
A computer works with software according to your demand. Just capture video and import into a video editing software that is premiere pro and edit. All is possible with the help of a computer or laptop.
3. Office Works
Office works are now easy, with the help of a computer machine. There are several heaps of different files, pages registers and the big ledgers. Now, it is the world of computers. Everything comes under the umbrella of a computer.
You can write, you can send, you can read books. In the developed countries they educate their youngsters with online classes and, this all is possible with the help of a computer.
In offices, there are different kinds of assignments as drafting, typing, making presentations, and certain types of calculations. Various software can use to do such works as MS Word, MS Excel, MS PowerPoint.
You can type letters, applications in Microsoft Word, and make calculations in Microsoft Excel. Similarly, you can prepare fascinating presentations in Microsoft PowerPoint. So, the main thing is the computer then software are helpful for you.

4. Designing of Building Maps
Building maps come under the umbrella of construction work. Building maps are necessary to get the complete idea about building construction. How many rooms and what kind of design you like for your home design, it is up to you. And all is possible due to the presence of a computer; a machine which can create preliminary buildings maps to accomplish your desire.
You can use AutoCAD software to design a building map, on which, construction work can be completed fastly, and accurately. While a building map designing, different rules are used that can be performed with several automatic and repetitive functions to complete a task.
According to Designing Buildings blog, the starting point for the use of computers, in the construction were nearest to the structural calculations. In this regard, civil engineer Zuse is premeditated, as the central pioneer in computer technologies.
In 1941, the world first, functional program-controlled turning, was completed, and a computer named as z3. These structural calculations, what are the basics of computer-aided design used in the aircraft industry in 1960. Then it comes in 1986 in the sector of architecture, computer-aided architectural design. These software programs started to improve the drawing process in 2D.
In 1990, these drawing tools emerged which provided the possible share in the 3D drawings, and then, subsequently, object-oriented designs developed. Today, these tools used for various functions in human life.
