Four CAUSES of Computer Problems

1. Electricity is not stable

Electricity as an source energy in the operation of computers is very influential in the process of working on the computer. Unstable voltage will make some piece of computer hardware will eventually weaken and significant effect on the working of the computer, such as the slow pace of work on the computer that will end any damage to computer components.To avoid this, we need to use a tool that can stabilize voltage, for example stavolt, UPS, etc..

2. Air circulation

It is important to note the use of computers both PC and notebook is air circulation. Good air circulation will reduce the temperature on the computer remains stable. So the air temperature is too hot will cause the components of the computer does not work properly, and eventually damaged or frayed. So install a cooling system on the computer, we can add an additional cooling fan, or install air conditioning in our computer room.

3. Virus
Virus here is not micro-organisms, but a program that deliberately to disrupt the computer's operating system. Destructive file system and is usually run automatically on a computer system that has been exposed to the virus. Virus problems can be minimized by installing some anti-virus on computer, but anti-virus should be updated regularly in order to remain sensitive. For computers that are used by many people it is worth the hard disk where the operating ystem we freeze with the software freezer, can be searched on google browser engine.

4. Computer Usage Patterns

pemakakaian computers are not careful will cause things to happen that are not desirable, such as a computer is dropped, spilled water or coffee, etc.. This would be very detrimental, because of our carelessness so try to put your computer in a relatively safe place, and when working with computers do not perform activities of eating and mnum in front of a computer can smoke if we do not well, that's important.

The Main Components of Computer

Have you ever asked what are the main components of computer are you using? will certainly be a very funny if we can not answer it, while we are working with computers every day.
In general, computers that we use for work is composed of basic equipment are a motherboard, a Central Processing Unit (CPU), memory and a hard drive. These 4 components are installed in a computer case to which are attached a monitor and a keyboard and a mouse. This makes up the basic computer.

Main board / Motherboard

The motherboard (sometimes called the mobo) provides the foundation for the rest of the computer components. Everything is attached to the motherboard -- the CPU, the memory, the monitor, the mouse, the keyboard, add-on cards, and extra peripherals like printers, scanners, and speakers. We could say that the motherboard is like the nervous system and skeleton of the human body -- it provides support for the internal components and also passes information between all the computer parts.

CPU /Processor

If the motherboard is the nervous system, the CPU is the brain. Most of the mathematical manipulations that make computers operate are done by the CPU. Other components may also have their own processors, but the results still have to be passed through the CPU.

The speed of the computer is usually measured by the speed of the CPU. Even though there are other factors affecting speed, the CPU rating is usually seen the single most important measure of performance.

Modern CPUs are usually rated between 2.0 GHz and 3.0 GHz, although you see some models in the 3.5 GHz range. These numbers refer to the number of calculations the processor can make in one second, so obviously the higher the number the faster the computer.

CPUs generate a lot of heat, so they need a heat sink and fan to prevent them from overheating.

Memory (Random Access Memory)

RAM (Random Access Memory) is the part of the computer that stores information while the computer is operating. It is Random Access because the computer can get the stored data in any order, rather than synchronously. Generally speaking, the more RAM the better. 512 to 1024 megabytes is fairly common for memory.

The most common type of RAM these days is DDR-SDRAM which stands for double-data-rate synchronous dynamic random access memory. We already know what the RAM part means. DDR means that the data is accessed at twice the rate than ordinary RAM.

The latest type of RAM is DDR3. It offers even faster access rates that DDR and is quickly becoming the standard for computer memory.

Hard Drive

Since the data contained in RAM is lost when the computer is turned off, there has to be a place to store it permanently. This is what the hard disk is for. It also contains all our personal work as well as the operating system. An operating system like Windows uses around 4 gigabytes of hard drive space, and the extra space can be used to install computer programs and to store personal data.

Eighty gigabyte hard drives are the most common, but they are available at up to 400 GB, and several hard drives can be installed in one case.

In addition to these four basic components of a computer requires other supporting components to be used optimally by the user. All that is needed to complete the basic computer system is a monitor, keyboard and mouse. Accessories like a printer or scanner can be useful for office work, and gamers will probably want to add speakers and joystick controls.

To get the best performance these components must integrate well. The motherboard is the most important component for determining the type and specification of the other parts so choosing an appropriate one for your computer needs is very important.

Hopefully this discussion can increase your knowledge and your knowledge to make reference materials.

Computer Definition

The computer is a set of electronic tools that work systematically aiming to create an efficient job. computer equipment can be divided into two, namely hardware and software.
 
HARDWARE is a computer device that has a dimension of space in other words can be seen by our eyes, and can be touched by our hands.
 
SOFTWARE is a computer device that only we can take advantage of its existence, in other words can not be seen and touched, because the only form of writing software or script programs designed to run and control the hardware work.
so between hardware and software tied to each other existence.
