What Is Computer Hardware ? | Computer Hardware Components And Features – Best Information

What Is Computer Hardware ? – Best described as a physical component of a computer system, including circuit boards, ICs, or other electronic devices. A perfect example of hardware is the screen displaying this page. Whether it is a computer monitors, tablets or smartphones. This is hardware.

Without the hardware, the computer wouldn’t exist and the software wouldn’t be available. The photo is of a Logitech webcam, which is an example of an external hardware peripheral. This hardware device allows users to take videos and photos and send them over the Internet.

Hardware Type

There are two main types of computer hardware: internal hardware and external hardware

Internal Hardware – Internal Hardware that is in the computer and is in the computer. Internal hardware is called internal hardware.

Example – Internal Hardware

1. Motherboard

2. Processor

3. Fan

4. Heat

5. RAM

6. Rom

7. Network card

8. Sound Card

1. Motherboard

It is known as the main part of the computer. Also known as a system board. This is the main printed circuit board that contains the sockets that receive power and communicate with the CPU and RAM. The motherboard, also known as the main board, is the main circuit board inside the computer to which the central processing unit (CPU), memory, expansion slots, drives, and other peripherals are connected.

The circuit on the motherboard facilitates communication between all the devices in the computer and is important for system performance using items such as CPU and memory.

The core circuit of a motherboard is called a chipset, and the manufacturer of the motherboard is usually not the manufacturer of the chipset. Intel manufactures motherboards with their own chipsets, but buying a motherboard brand such as Gigabyte, Biostar, ASUS means a board with a VIA, Nvidia, SiS, or Intel brand chipset. Means to buy.

2. Processor (CPU)

The processor processes all instructions from the hardware and software. Processors are also the engine of the brain and powerhouse, or computer, and run millions of processes. There are different types that need attention. First, there are two types of processors, one made by Intel and one made by AMD. These are two different brands in the industry. Currently, i-core is a popular product line of processor models currently in production.

Most computer ads show these processors on painted parts. Intel likes to create chips with integrated graphics. These processors have speeds dedicated to 3D applications such as movies and games. AMD processors are my favorite because they are as fast and cheap as Intel and more flexible when it comes to overclocking.

3. Fan

A hardware device that cools an entire computer or computer device by circulating air to and from the computer or component. The photo is an example of a heat sink fan. Located at the top of the processor or CPU. This helps to draw out the bold heat of the processor and helps the cooler.

4. Heat

A heat sink is an electronic device that incorporates a fan or filter device to cool hot components such as processors.

5. RAM

RAM is divided into chunks of information, and each chunk can be addressed by an unusual number called an address. For example, each address sends 16 bits of information, has 4096 addresses, and provides 16 * 4096 = 65535 bits of information, or 8KB of kilobytes.

RAM Space and Space on Your PC – Most PCs now have 512MB of RAM. You are free to put more RAM into your machine. However, usually only one control can install as much RAM as possible on a PC system. RAM is not optional as its name guides you in what to consider. RAM is very limited and you can directly determine the storage capacity.

RAM Type- RAM is recognized as a separate microchip. That is, it is partitioned. Another type of RAM is a unit that connects to a slot on the motherboard of a PC. A system of electrical trails to the CPU allows the RAM links to be flushed.

Why do you need RAM? RAM refers to the essential purpose of recovering data that needs to be maintained in fast mode. This behavior is similar to the usefulness of the human brain in retrieving the necessary information from short-term memory. RAM support was required to open the document and use the program on a PC system. Customers playing multiple games with a full image or having multiple databases open on their PC will need to use additional RAM.

This gives them better access to the data that has arrived by that time. RAM will be supported in a short period of time. However, it can generate data faster and has few problems for PC users.

How does RAM work?

RAM is less technical, so it is a sequence of memory packets, indicating power. Each packet is a symbol with a symbol and no zeros. Older forms can be transferred via quick information. Obviously, the larger the cell, the more information can be sent through the cell. RAM is readily available and some systems work better with RAM chips of the same size.

You can improve the RAM of each system, so if you are using a desktop or notebook PC, you can use even more RAM. The main thing you need to do is make sure you have a free outlet on which you can mount the memory chip. Whenever you buy new RAM for your machine, you should do proper research.

6. Rom

What does ROM do? ROM stands for read-only memory. This is a kind of fixed data storage device, manufactured with fixed materials. This refers to a computer memory chip that contains persistent or semi-persistent pre-recorded programs. This is non-volatile memory. This means that content will continue to be available after you shut down and restart your computer.

It helps to keep the information every time the computer boots so that the computer can check the hardware and load the operating system into RAM. RAM is an abbreviation for random memory. When you refer to the ROM on your computer, you usually refer to the oldest mask type of its kind. It cannot be changed and the required data is permanently stored. Changes have been made since it was first invented in 1956.

For example, you can change both the EPROM, which represents Erasable Read-Only Memory, and the EEPROM, which represents Electrically Erasable Programmable Read-Only Memory. EPROMs are erased when exposed to strong UV light for more than 10 minutes and can be rewritten when a higher voltage than normal is reached.

These chips can typically be used for about 1000 cycles, but may be considered useless when the number of cycles reaches the limit. EEPROM, on the other hand, is similar in structure to EPROM, but is more convenient in the sense that its contents can be electrically erased and rewritten.

It is used for backup because the storage form cannot be modified. Flash foam is now widely used as a mass storage device or a secondary storage device for files. This is called flash memory and is the latest modified version of EEPROM. Flash drives are widely used by almost everyone and will gradually replace the older format, reaching 320GB by 2021.

When referring only to memory read, write, and write speeds, there are two types of speeds. Read speed refers to taking data into a drive and using it to work on your computer. Write speed is primarily a process in which data is written to memory, so it can only be applied to new forms, not to forms that contain mask forms.

In other words, read-only saves the BIOS and firmware in memory. Memory isn’t hardware or software, so it’s somewhere in between. ROM acts like a security check where everything has to pass the check. The same is true for computer ROMs, as every program must go through routines to access all kinds of hardware components.

7. Network Card

This is an expansion card that allows your computer to connect to the network. Home networks and the Internet using an Ethernet cable with an RJ-45 connector.

8. Sound Card

A sound card is an expansion card or IC on your computer that produces sound that you can hear through speakers or headphones. The computer doesn’t need a sound device to work, but it’s somehow included on every machine because it’s in an expansion slot or built into the motherboard (onboard).

9. SMPS- (Switch Mode Power Supply)

A switch-mode power supply (SMPS) is an electronic circuit that converts power using a switching device that turns on and off at high frequencies and storage components such as inductors and capacitors that supply power during switching. Conduction state.

10. Modem

The modem modulates the outgoing digital signal from a computer or other digital device, converts the analog signal into a traditional copper twisted pair line, decompresses the incoming analog signal and converts it into a digital signal for the digital device.

External Hardware – Hardware that is external to your computer is called external hardware

Example- External Hardware

1. Keyboard

2. Mouse


4. Mike

5. Printer

6. Projector

7. Joystick

8. Speaker

9. Scanner

1. Keyboard – You need a keyboard to “communicate” with your computer. Without it, even the best computers are just another expensive electronic device.

The computer keyboard was a descendant of the typewriter, and the original model had only 84 keys. However, the keyboard has evolved to include additional function keys (101 or 104 are the most common) pre-programmed for specific applications. Function keys can be operated independently or used with other keys. (Everyone knows what ctrl-alt-delete does-yes?) Many of these additional keys help users find edits more efficiently, “shortcuts” or “shortcuts” or ” It is called a “hotkey”.

2. Mouse – If you’re wondering what a mouse (that is, a computer mouse) is, it’s the device that controls the movement of the cursor on your computer monitor. The mouse can simplify many tasks for the user. Thanks to the mouse, the tasks that allow dragging, dropping, opening folders, drawing, etc. have become much easier. There are three main types: mechanical, optical and laser.

3. UPS – First of all, what is a UPS system? In essence, a series of batteries work together to maintain power to many important parts of the device, but it is difficult to identify serious obstacles. What the UPS does is protect the equipment from power-related factors such as voltage fluctuations, transient disturbances, frequency fluctuations, and general voltage drops.

The role of UPS systems in this highly technologically advanced world has grown tremendously over the years. Facilities are aware of the need for such systems and are more important than ever. Loss of commercial power often takes 10 seconds or more for a generator at a particular facility to restart and transfer power to an emergency power source. It’s important to note that most electronic components in the equipment sold today can’t or can’t tolerate more than a few electrical interruptions before they finally shut down.

4. Mike – The microphone has a sensor configuration that converts an acoustic signal into a proportional electrical signal. You can then amplify, manipulate, transmit or record electrical signals.

Early models usually consisted of a paper cone and an electric coil that passed through a magnetic field. This is the same way that today’s Hi-Fi speakers are manufactured. Critical stage microphones are typically created using this method, called dynamic microphones. Before the alternator, it wasn’t long before a smaller way to capture sound electrically was discovered. Some of the other major types of microphones currently available are:

Condenser Microphone-Uses two plates arranged as condensers. One of the plates is vibrated by sound waves, changing the capacitance of the plate and allowing the voltage to change proportionally depending on the gap used.

Electret Microphone-Electret Microphone-Like a condenser microphone in principle, the capacitance plate is made of a charged polymer. This means that no actual power is used to generate the signal. Almost all cheap things like cell phones and PC headsets are of this type.

5. Printer – The world we live in is one of full automation. Past documents were printed only to the types of authors found in most offices. However, over time, work requirements have changed, and with the advent of computers, the entire scenario has changed completely. In that case, the document had to be printed on a special machine called a printer, which was completely different from the typewriter.

There are different types of printers. It will soon define the type of printer that currently exists.

  • Dot Matrix Printer
  • Laser Jet Printer
  • Bubble Jet Printer
  • Inkjet Printer
  • Color Laser Jet Printer
  • Flatbed And Vertical Plotter

Apart from this, there are several multipurpose machines that act as scanners, copiers, and printers. If installed away from your computer, it works very well as a copier or fax machine.

The printer uses its own software called drivers. The driver links the printer hardware to the computer software and controls all the functions of the printer. The printer role is not limited to its use, as it is used in place of computer-generated documents. It is also used as a fax machine. Special fax software installed on a computer connected over a telephone line. Faxes are received by the printer even if the printer is standalone and not in use by the operator.

Similarly, the term print is primarily referred to as computer-processed document generation and is used as an image or as text or image after scanning.

From a connectivity perspective, there are two types of printers: network printers and non-network printers. The network printer is not directly connected to your computer. Instead, it connects to a host server that collects data from the terminal computer and sends commands to the printer on a first-come, first-served basis. Standalone or non-network printers that are directly connected to a terminal computer or stand-alone terminal operate directly from that machine via commands.

Multipurpose machines that combine printers, scanners, copiers, and fax machines are also available in two different connection topology modes. As an expert, you should avoid all-in-one printers. Disassembling one component also removes the other running components.

These printers do a lot, but they don’t match the quality of professional and commercial printing. If you need high quality or bulk printing, you have the advantage of being able to do it more professionally than a multipurpose printer.

6. Projector – Projectors are multimedia projectors that are used to transfer photos and videos to a larger screen or surface area. They are used in different situations and environments to display information to a large number of people at once. The lamp works by passing an electric current through the ARC gap that holds the ultra-high pressure mercury vapor.

This current then illuminates the steam and the lens emits bright light to the DLP digital light processing or LCD LCD display panel. The projector lamp is the most important part of the projector. You can’t see anything without the lamp. The projector will last for years, but it is the lamp that needs to be replaced.

7. Joystick – Most games for PC can be played using a simple mouse and a simple computer keyboard. That’s the case for simple, average gamers. But if you’re a serious and hardcore gamer, those peripherals aren’t enough. This is why manufacturers have created and developed a variety of gaming tools to provide a more enjoyable and hands-on experience. And one of these great tool is the joystick.

Joysticks are typically compatible with game consoles such as the Xbox and PlayStation, but have been redesigned to be compatible with computers as well. Joysticks for PC are used in games like arcades and flight simulation games. Various joystick models are designed to suit a particular game type.

8. Speaker – A speaker is a device that converts an electrical signal into sound. It is an integral part of music systems, televisions, computers and radios. We listen to music and watch TV every day, but never think about how the speakers actually work.

Speakers work on the basic principles of electromagnetism. An electric current is passed through the coil of the wire to create a magnetic effect and charge the metal inside. After charging this metal, the diaphragm is excited and vibrated to generate sound waves. This is the most basic function of a speaker, which reverses the flow of electricity and transmits the vibration of sound.

Going deeper, the speaker has a basic design that includes a driver, cabinet, bass reflex port, spring clip, and crossover circuitry. The driver converts the electrical signal into an audible sound. It consists of a coil of wire connected to the amplifier. They fall into four types based on the overall audio spectrum. The various combinations of drivers determine the speaker design. Low frequency drivers have the ability to provide additional bass.

The medium frequency driver is responsible for the vocal part of the music. High frequency drivers, also known as tweeters, are responsible for delivering high frequencies. The full range driver combines a high frequency driver with a medium frequency driver for balanced audio playback.

9. Scanner  – A scanner is a device that converts objects, photos, and documents into digital images. Normally, the scanner is connected to your computer and the digital images converted by the scanner are transferred to your computer. The image may or may not be edited on your computer and can be simply saved by email, fax, or as a record of what the owner wants to do with the image.

Scanners come in a variety of specifications. These are primarily image sensor types, color or monochromatic scans, optical resolution, and speed. Scanners with higher quality image sensors provide more colors, better color fidelity, and sharper images. Color scanners provide better images.
