What is Computer?

                A computer is an electronic machine and also a device that accepts information (a form of digitalized data) and operates it for various results built on a program, software, or classification of directions on how the data is to be handled.

Importance of compute

•       Home   

                 Computers are also used at homes for some resolutions like online bill fees, 123 movies or displays at home, home tuition, social media contact, singing games, internet contact, etc.

• Medical Field

                      Computers are used in hospitals to maintain a record of patients’ accounts, identification, X-rays, live checking of patients, etc. Neurosurgeons today use mechanical operating plans to achieve slight procedures, and behavior operations at all

• Performing

                       Computers help to watch movies online, play games online; act as a virtual entertainer in playing games, heeding music, etc. MIDI mechanisms really help people in the performing industry to record music with fake devices.

• Engineering

                     Computers are used to achieve numerous responsibilities in activities like dealing with accounts, crafty resolution, constructing virtual model products, interior designing, video conferencing, etc

• Education

                       Computers are also used in the education division to conclude online lessons, online studies, discuss e-books, online tuition, etc. They help in the improved use of audio-visual benefits in the education field.

• Government

                           In government sectors, computers are used in data processing, upholding a record of nations, and are associated with a paperless environment. The country’s security groups have greatly profited from computers in their use for projectile growth, settlements, missile promotions, etc.

• Banking

                        In the banking sector, computers are used to supply specifics of clientele and behavior dealings, such as drawing and security of cash-concluded ATMs. Banks have concentrated physical mistakes and payments to an unlimited amount concluded general use of computers.

Types of Computer :

• Supercomputer.
• Mainframe.
• Server Computer.
• Personal Computer or PC.
• Microcontroller.
• Smartphone.

Basic components of computer hardware 

1. Central processing unit (CPU)

                         The CPU controls the computational methods and connects with the other components of a private computer. A computer's CPU may be one of the maximum difficult quantities of the computer because of its details. If a computer is facing CPU problems, a computer professional can start by testing the follower and washing out any dust or rubbish secret the machine.

2. Motherboard

                              The motherboard delivers the building for all new mechanisms and fixes them, while also providing a way to issue power, supply evidence and attach to procedures such as a copier or mouse. It controls how data transfers and what type of monitor or screen device to use, for example. It houses the CPU, recollection, and inferior storing devices such as solid drives.

3. Random Access Memory (RAM)

                             RAM is where data survives provisionally while its presence is actively used by platforms, such as when a worker presents a computer request. A professional can see how to classify the type of RAM in a computer, how to exchange it if it's defective, and how to analyze difficulties with replication data from one position in memory to additional.

4. Video graphics array port

                      A video graphics array (VGA) port is a video contribution that is mainly used on PC monitors. Troubleshooting a VGA port could contain confirming there isn't a movable connection, a defective cable, or a destroyed monitor. An additional profession a computer operator may do is use beaten air to shower inside the VGA port to confirm it's free of dust.

5. Power supply

                         A power supply delivers power to all mechanisms of a computer system. Usually, it's a power string attached from the back of a PC post into a power hole. An operator may troubleshoot the power supply by rotating off the computer, clearing and cracking the power supply string, or trying a new string or channel.

6. Cooling fan

                        Cooling fans are a computer's system to drop hotness. Various computers have other than one cooling fan to help workers who track their computer greatly, such as video spilling or betting. A computer operator may need to fix a PC's cooling fan if a user poster their computer's hotness.

7. Hard drive                        

                      Hard energies are recorded storage devices used to supply documents, platforms, or other evidence on a computer system. They use magnetically treated discs called hard disks that store digital illustrations of evidence. If a hard effort flops, a computer worker might irregularly a crooked hard drive. They may use data retrieval software to repair the computer or may replace the hard drive.

8. Monitor         

                   A computer monitor is an electrical device that exhibitions what's what platforms are an organization on your computer so a worker can see. Some computer operators may uniform anti-static ornaments when treating computer monitors to sidestep still electricity.

9. Printer

                  This is a mechanism that produces prints of writing or pictures on paper using ink. Popular copiers contain laser or inkjet and computer operators may be experts in troubleshooting problems through various kinds and multiplicities. Computer operators may facilitate printers including verifying power is an organization to the mechanism. They may also form to see if the paper plate is complete and organized for production. Operators strength change or replenish any ink containers and cleanser.

10. Scanner

                      A scanner is a scheme that numerically prints a duplicate or and makes it available as a file for contact on a computer. If a scanner flops, a computer operator may remove the protection and sensibly check if it has any injury. If there are no evident problems, then they may check the power construction chain

11. the Computer mouse

                               A computer mouse can have a cable or is wireless and is an involved device used to control a marker on the computer monitor. A wired computer mouse has a string that connects to a USB seaport on a computer while a wireless mouse has no physical construction with a computer system. In its place, a wireless mouse connects using a converter that is usually worked into an available USB port and runs off its own strings using Bluetooth technology.
