Add a Teacher Note to share how you incorporated it into your lesson. Your motherboard is the central nervous system of your computer. All the veins between components hook into it. Without your motherboard, you'd have a case of rattling components with no way of communicating. The motherboard is even more important than the CPU, because your CPU wouldn't even be able to turn on without a motherboard. There are several sizes of motherboard. The CPU creates another variation in mobos short for motherboard.
All manufacturers of CPU use several standards of sockets each. None of these standards are compatible with motherboards not designed for that CPU. Motherboards have PCI slots usually, which allow for expansions such as graphic cards, network cards and firewire cards. My computer, and many others have 4 of these slots. Your CPU Central processing unit, or processor is the brain of the computer.
Without it, you computer would not respond to anything, nor would it be able to process data. This is vital to the system as it causes all functionality. Above your CPU is a cooling fan.
As the hottest component in your system, the CPU has two defenses to protect it from overheating. Firstly, there is a paste on top of your processor called the thermal compound. This is also referred to as thermal putty and thermal paste. It's job is to dissipate heat before the fan creates hot air with the heat. On top of your thermal paste, there is a cooling fan which basically blows away the heat as hot air. Not much to explain there Your computer may have more fans, aside from the CPU.
All will have one in the PSU, and many have fans around the system. These are case fans, which just help cool all the components and take any lingering hot air from the CPU cooler away. Ram is a mission critical component. Whatever you do on a computer stays running even while it isn't saved. This is down to the RAM.Base58 encode hex
The RAM stores all the information you can see, window sizes, buttons, your cursor, mouse movements etc. RAM only stores this temporarily, and if any information is left on it, it will be cleared when your system turns off.Kopi setia alam
Each year, the average amount of RAM computers have grows, because the amount programs need grows as they advance. Almost all systems have them, because they are so commonly used. You probably know about CDs etc, so I need not explain them. They are permanent storage, and can be powered down while still keeping information on them, unlike RAM. HDDs are made from metal disks, and function similarly to digital cassettes. Information is encoded, then written on to the platters using magnets.Computer hardware maintenance involves taking care of the computer's physical components, such as its keyboard, hard drive and internal CD or DVD drives.
Cleaning the computer, keeping its fans free from dust, and defragmenting its hard drives regularly are all parts of a computer hardware maintenance program. Maintaining hardware helps to extend the computer's lifespan.
It helps to prevent wear and tear, and keeps the system functioning smoothly. Keep your system functioning smoothly by managing hard drive space, scanning for system errors and regularly defragmenting the hard drive. Virus protection is also important, as some viruses can interfere with computer hardware. Keeping computers away from dust and dirt, keeping them clean and avoiding extreme temperature changes all help to maintain hardware, according to Gateway.

Note : The damage to components during improper handling or force majeure are not subject to warranty and their appearance should be stopped to avoid subsequent inconvenience. Thunderstorms often cause chain malfunctions and in that case the malfunction caused by a irregularity of another component is not subject to warranty.
Because of that, unplugging your computer is good advice. A UPS device doesn't protect from lightning strikes. A lightning strike can damage your computer through a phone cable attached to a modem even when the computer is turned off. This especially means clean the dust in the casing, the fan and the cooler.
For this you will need a brush with soft hairs, a spray with compressed air and a rug. It is necessary that you check your fans from time to time. If you notice that your fan is turning slowly, if it is loud, or it doesn't turn at all, you probably need to clean it or replace it if cleaning doesn't help. Note : Regular cleaning is recommended to be done by a competent person. For cleaning, don't use liquid washing solutions like water, alcohol Vacuuming the dust by sticking a vacuum hose in your casing can cause component damage.
Cleaning the casing with a high air flow compressor can cause damage. Touching the component with bare hands, can cause component damage due to static electricity. By following these tips you can save yourself time and money, and with that prolong your computers lifetime.
No matter how great your computer knowledge is, we recommend that you take it to a service regularly for control and maintenance. Now that you've gotten free know-how on this topic, try to grow your skills even faster with online video training. Then finally, put these skills to the test and make a name for yourself by offering these skills to others by becoming a freelancer.
