Important Computer Hardware Components and Parts

Computer hardware consists of the different components of a computer including the CPU or the Central Processing Unit, mouse, keyboard, monitor, hard disk, RAM or memory, drives such as the DVD, CD, optical, tape and so forth. All these components are essential for the proper functioning of a personal computer.

Understanding Computer Hardware in Detail

The whole computer is available with the above mentioned components but it is also possible to purchase these components individually from many of the online and offline stores. Some of the most important components include the following:

Central Processing Unit or the CPU: the CPU refers to the processor of the computer. Although there are a wide number of companies that manufacture CPUs or processors for personal computers, the Pentium chip manufactured by Intel is widely and commonly used by most of the manufacturers.
Keyboard: most important computer hardware includes the keyboard which is essential to enter commands and words. Every key in the keyboard is a representation of an alphabet, number, sign, function and so forth. There are keys which represent actions like Delete, Enter, Alt, Ctrl, Page Up, Page Down, Home, End and many more. Each different key has a specific function.

There are 101 keys in an ordinary standard keyboard. Keyboards which are ergonomically designed have special features to make typing easier. Each key has two characters which can be typed by pressing the Shift key. The Ctrl, Alt and Shift keys are known as the command keys.

Mouse: Important computer hardware also includes the mouse. It is used for navigating on the computer’s screen, to click on options, to select objects and to access information. There are usually two buttons on the mouse- one on the left which is used for selection and one on the right which is used to access information. There are different types of mouse available today which include optical mouse, scroll mouse, laser mouse, ball mouse and so forth. The scroll mouse, or the wheel mouse, has a plastic wheel in between the left and right buttons on the mouse. This important computer hardware also includes the optical mouse which sends optical signals to the computer. The ball mouse includes a ball in the mouse casing which moves when the mouse is moved on the pad. This movement sends the required signal to the computer.
Hard disk: computer hardware also includes hard disk which is a device used for permanent storage of data. The performance of a computer depends on the rotation speed of the hard disk. The higher the rotation speed, the higher the performance of the computer.
RAM or the Random Access Memory: RAM is also a computer hardware that stores information temporarily. But however, while rebooting or turning off the computer, this information will be erased. The performance of the computer depends largely on the RAM and if the size of the RAM is larger, the computer will perform better and faster.

Computer hardware also includes components like sound cards, digital cameras, scanners and modems. Different types of components are available and it may differ according to the type of the computer.

Basic Guide for Selection of Computer Hardware

Although computer software is the most talked about topic in the IT world, computer hardware is certainly as equal in importance if not more. Like day-to-day problems with the software installed on the computer, computer hardware also faces similar issues if the hardware selected has not been appropriate. To top it all, hardware problems are more troublesome than software hence they certainly require excellent research and good purchase decisions. In addition, computer hardware composed of quality products produce excellent performance without any hardware issues for long time.

A good amount of knowledge is required in addition to a little bit of research to be able to buy quality computer hardware. If you are buying individual components separately, you must know their importance and functionalities in order to select a good component.

Computer Hardware Guide

Does the technical name of different component of a computer, such as RAM, processor, scare you off?

In this article, we will be covering most of the hardware in regardless of the form size (physical size of the computer casing)

Essential Computer Hardware consists of

Mainboard
CPU
RAM
Hard Disk Drive
Graphic Card
Power Supply / Casing
Keyboard / Mouse
Monitor
DVD Writer

Mainboard (Motherboard)

This is the biggest piece of hardware in the system. This is where various other essential components connect onto it, such as CPU, Ram, Hard Disk drive, etc, to it. Modern mid-range mainboard usually comes with add-on component such LAN port, sound card and graphics card.

As other hardware connects to the mainboard, it is important to ensure that the mainboard purchased is of high caliber and has at least the add-on component as stated in the paragraph above.

Central Processing Unit (CPU)

This is one of the computer hardware that determines the speed of the whole system. The other determining hardware are the RAM and Hard Disk Drive. Single Core CPUs are almost obsolete and are much slower compared to their Dual Core / Quad Core counterparts.

Usually a numeric figure is stated and that is the clock frequency, commonly known as the speed of the CPU. Usually the higher the clock frequency, the faster your data can be processed.

Ram

Known as Random Access Memory, are memory chips where data are temporary stored. By storing the data on RAMs, the CPU is able to process the data in a shorter period which leads faster execution of the instructions and tasks assigned to the computer.

Usually a numeric figure (in Gb) is stated and that is the physical size of data the RAM is able to store.

Hard Disk Drive

This computer hardware keeps all data permanently, unlike the RAM which will erase data if the computer is shut down. Comes in sizes of 2.5″ (for laptop) and 3.5″ (for Desktop)

Usually a numeric figure (in Gb) is stated and comes in various capacity. A rough calculation Assuming a 4 min long music song is stored in mp3 format and takes up 4mb worth of space in the hard disk. 160Gb will be able to store around 40,000 songs!

Graphic Card

As stated, this card is initially responsible for displaying images onto the monitor. However, due to the high rendering first-person-shooter games being produced, gamers will demand their graphics card to be better than the CPU. This is due to the fact that the graphic card will handle all taxing gaming images which the CPU was unable to process. To meet up the demands, even graphics cards are going dual core!

Power Supply Unit (PSU)

The life of the computer! This computer hardware sends power to various devices, such as the mainboard, hard disk drives, etc.

This is often the most overlooked hardware and is frequently compromised due to budget constraints. However, by cutting down on getting a good PSU, risks such as electric shock and under-current may occurs which could instantly destroy the mainboard and other hardware by providing the wrong current or voltage!!

Computer Casing / Chasis

Computer case is the tough armor to protect the dedicated various computer hardware.

Casing are important as they ventilate and regulate air flow to prevent overheating of the essential computer hardware.

Optical Drives

Commonly known as CD-ROM / DVD-ROM or DVD Writers, this allows reading of various CDs/DVDs. ROM hardware are only able to read from CD / DVD, while DVD Writers enables writing (copying of data) to the discs.

The latest technology for Optical Drive is currently Blu-Ray ROM will allows reading of Blu-ray disc. Due to the high cost, it is not widely included in systems.

Monitor

Is a visual display unit that shows images generated by the graphic card. CRT monitors that are working today are using older technology which consumes more power. Mainstream monitor manufactured are now mostly LCD due to their compact size and cheaper cost to manufacture.

LCD monitors come in various sizes, ranging from a minimum of 15″ to up to 70″!

Keyboard and Mouse

Is the hardware to input data and commands into the computer.

Define Computer Hardware

It is quite well known that the working of the computer is pulled by hardware and software. One can define computer hardware as the electronic, magnetic, and electric devices that carry out the computing functions. Hardware is the physical components of the computer like microprocessor, hard disks, RAM, and motherboard. The peripheral devices such as monitor, mouse, keyboard, printer, and speakers can also be included in the list of hardware parts. The programs that run on the computers like Windows, C++, and Photoshop are the software parts of the computer. A good example for an easy understanding of hardware-software definition is music CDs. The actual compact disk is the hardware, while the songs and music in the CD are the software parts.

There is another way to define computer hardware. Hardware devices are the executors of the commands provided by software applications. For example, let us see what happens when you click the print button of the web browsing software. The software application provides a command to the processor, which is the central part of all computer hardware. Processor in turn checks for an attached printer. If the printer is ready, the software will get a positive response from the processor. Then the software application provides instruction to the printer via the processor to print the web page. In that sense, hardware parts are the foot soldiers and software applications are the commanders in the digital operation that takes place within a computer.

The main player of computer hardware is undoubtedly the microprocessor. It is the sun in the solar system of computer hardware devices. It is the central component and all other components work around it. It is an integrated chip on which a number of functions are incorporated. Two specifications determine its efficiency. One is its processing speed, which is measured in gigahertz. The other is its bit rate. Commonly available processors are 32 bit and 64 bit. The bit rate is a measure of the efficiency of a processor to carry out multiple operations at the same time.

One cannot define computer hardware without mentioning the two types of memory used in computers. One is permanent memory. It refers to the magnetic storage capacity of hard disk. It is measured in gigabytes. The second is RAM or random access memory. This memory is able to store data only when the computer is switched on. The memory will lose all the data when the computer is switched off.

Another important product that one should mention when one defines computer hardware is motherboard. It is the electric and electronic circuit board on which all the other components are inserted. There are several other kinds of products such as sound card, video card, network card, and modem that complete the hardware spectrum.

Purchasing Computer Hardware From the Internet

If you want to purchase a computer or computer accessories, you can find plenty of opportunities on the Web. This article presents various options that have been chosen among online hardware vendors, computer hardware stores, computer shops and internet companies.

You can find online a wide selection of computer hardware and computer related items such as PC, laptops, notebooks, palmtops, computer accessories, printers, scanners, wireless networking, consumables, internet access, website hosting, computer software, software tools, games and much more.

Direct Vendors and IT and Technology Distributors

Computer Hardware Terminology

Unlike other electronic devices, computer is the sum of its parts. Nobody cares about the specifications and make of the picture tube of a particular brand of television. But in the case of computers, more than the brand name the specifications of its components like processor, motherboard, RAM, hard disk, and suchlike are the things that a knowledgeable consumer first asks about. Here is computer hardware terminology in a nutshell.

Processor or microprocessor is a powerful IC chip on which a number of functions are incorporated. It is the heart and brain of the computer rolled into a chip. Its efficiency depends on its speed of processing, which is specified by its frequency and it is denoted using gigahertz. The higher the speed, the better will be its functioning. Also, there are several types of processors such as 32-bit processor and 64-bit processor. The bit rate is not actually a yardstick of speed. The larger bit rate means the processor will be able to efficiently do several computing processes at the same time.

Another main item in computer hardware terminology is motherboard. In simple terms, it is the platform on which all the other components are electrically fitted in. Over the years, a number of additional functionalities such as sound card, graphics card, and networking card are slotted on to the motherboard. When selecting motherboard, one should make sure that the motherboard is compatible with other components such as processor, hard disk, and RAM.

Hard disk and RAM are the next items in the hierarchy of computer hardware terminology. A computer has two types of memory. Permanent memory is stored magnetically on hard disk and it will be stored in the disk even after the computer is shut down. On the other hand, RAM or random access memory will be off once the computer is shut down. It is the kind of memory on which the functional information while running a computer, like running programs and unsaved data, are kept when computer is running. When you save a file, the data is stored to hard disk from RAM.

Nowadays the memory capacity of hard disk is skyrocketing. It is all set to break the upper limits of gigabytes. Comparing to that, RAM was a slow starter. It is still ambling along the lower middle part of gigabytes. Lay users do not need a RAM with a large capacity. The price of RAM increases with the rise in memory capacity.

Computer peripherals like keyboard, mouse, monitor, CD or DVD drives and writers, speaker, and webcams are all part of a large list called computer hardware terminology. There are other hardware items also such as graphics card, sound card and video card for sound recording and video editing facility, and internal and external modems for browsing the internet.

Computer Hardware

You have to know the different parts of your computer particulaly the computer hardware. Rarely do you find a home with no computer nowadays. Some people call it the computer age and it is true because computers have already become a very important part of our lives such that we can no longer do away with computers. We bring these gadgets wherever we are. You can see people, adult and young people alike, bringing their notebooks in restaurants and cafeterias. They are taking advantage of the WiFi zone. Children cannot study without computers because all the data that they need are stored in the World Wide Web. It is always easy to browse through the internet. Just type the data that you want in the search bar and click enter. All the relevant information regarding that topic will immediately pop out on your screen. There is no need to go to the library and read all the thick books piled on the cabinet. All the data you need can be accessed through the computer.

There are different types of computer, from the desktop and laptop to the mini notebook that most people always carry with them. If you are a writer, you will definitely treat your personal computer as your partner. You need the computer in your daily activities. You simply cannot live without it because all your articles and files are stored in the computer. There is no need for you to bring thick notes anymore. This generation is indeed very lucky to have such a powerful technology. That is the reason why you should take good care of your computer hardware. There are two major components of the computer which are the hardware and the software. The hardware is everything that you see on the outside, we have the keyboard, screen or what others call monitor, mouse, speaker and the system unit or the tower. You might be wondering why do need to know all these components. The answer is quite simple and that is so you will know how to take good care of your computer.

Most cases of hardware failure are due to lack of proper maintenance. You cannot ignore the fact that your computer needs to be cleaned also especially if you bring it outside your home. Dust particles can easily accumulate. The time will come when you might be wondering why your computer does not turn on and you will later find out through the technician that dust has already made its way through the small holes and that is what’s causing the problem. It is very important that you have a small soft brush so you could clean the unit every now and then. It is even advisable to clean it after using. Take good care of your computer because if it will be destroyed, the repairs will not only cost you lots of dollars, you will also lose relevant time that should have been used in working. The worst thing that could happen if you continue to ignore computer maintenance is that the unit might be totally destroyed and you have to purchase a new computer.

Buy Computer Hardware

Computer Hardware has developed extremely fast over the past few years. It is important to know what hardware you currently have and what hardware you want if you are upgrading or buying a new computer.

Many people lack the knowledge of what hardware is good and what is not, it can be researched easily but the best thing for you to do if you are not computer literate is to ask for help and advice – we offer free advice so why not give us a call, we can help you determine if your current system is upgradeable or help you with a brand new system.

Having the correct hardware is very important, without the correct hardware or a certain amount of ram you may run into problems when trying to run software. Software cannot run without the hardware which is why hardware can cost more than the Software.

Say some software needs 512mb ram to run and you had 512mb ram in your system this means it will run the software but at the bare minimal only and if you try to open anything else with that software open you will notice your computer reduce in speed, no doubt about it. When buying hardware it is important to write a list of what you will be using the Computer for, this will help determine how much ram you need and other things such as processor speed.

These days you can get top of the range processors for a great price, processors used to just run on one core but the latest processors are running on 2 cores, this is essentially double the speed and performance of previous processors, Duel Core processors are by far way better performance and speed for the cost. For the price you pay for a Duel Core processor you may as well fork out a few extra pounds to get one, it will benefit you in the long run as you should not need to upgrade or buy a new computer for a long time depending on exactly what you’re using the computer for. If you multi-task a lot then you should defiantly get a Duel Core processor, the latest Core2Duo processors from Microsoft are great performance and speed for the price you pay.

If you are into gaming then your computer will need to be a top of the range spec. You will need a duel core processor for definite and a lot of ram, possibly a big hard drive if you are a serious gamer. You will defiantly need a good graphics card, you can get the latest graphic cards for great prices, they will run most games at max graphics and performance, the more you pay for a graphics card the better it is going to be.

When buying or upgrading a computer you really need to think about what you need it for, if it is for word processing only then you will not need the best hardware, if you need it for gaming or 3D Design packages then you may need to get some of the best hardware available. For example Adobe Photoshop requires much more ram than Microsoft Word.

A lot of people don’t realize this but when you purchase a computer you need to take into account the ram that the Operating System will use, and any important software such as Anti Virus products, these also use resources, such as ram. People sometimes buy enough ram to cover their main software such as Microsoft Word and expect it to run fast but they do not take into account the amount of ram the Operating System uses, this is very important, make sure you buy enough Ram to cover this. When buying Ram it is usually best to buy double what you need to make sure you cover what you need + any other applications that you open would still run without slowing down your computer.
