Computer Components for Dumb
There are many fancy add-ons for computers, but the basic elements of the computer are simple and universal. If 1 of these key elements is missing, it is not a computer. The 4 essentials of every computer system are: a motherboard, a central processing unit (CPU), memory and a hard drive. These components are installed in a case to which are attached a monitor, a keyboard and mouse. This is the basis of your computer.
Motherboard
The motherboard ( “mobo” for short) is the foundation. Everything attaches to the mobo - the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even other devices like printers, scanners and speakers. The motherboard is like the nervous system and skeleton of the human body - it provides support for internal components and transmit information between the computer parts.
CPU
If the motherboard is the nervous system, then the processor is the brain. Most mathematical manipulations that make computers operate are done by the CPU. Other components May also have their own processors, but their results must still be adopted by the CPU. The speed of the computer is often measured by the speed of CPU. Although other factors also affect overall speed, the CPU rating is generally regarded as the most important measure of performance.
Modern processors are generally estimated at between 2.0 GHz and 3.0 GHz, although each month see increasing performance. This measure refers to the number of calculations the processor can do in 1 second. The highest number, the faster (better) the computer. CPU generate much heat this work, you need a heat sink and fan to prevent overheating. The heat is a big enemy of the computer and directly affects its lifetime.
Memory
RAM (Random Access Memory) is the part of the computer that stores information the computer needs to operate. It is Random Access because the computer can retrieve data in any order, not necessarily the order in which they are stored. Generally speaking, the more RAM the better. 512 to 1024 megabytes is common for memory.
The most common type of RAM these days is DDR-SDRAM, which is double-data rate synchronous dynamic random access memory. We already know what the party means of RAM. DDR means that data are available twice faster than regular RAM. The latter type of DDR2 RAM. It offers even faster access rates and is quickly becoming the standard for computer memory.
Hard Drive
All data contained in RAM is lost when the computer is off, what should be a place to store them permanently. That is what the hard drive. He holds the operating system. An operating system like Windows uses around 4 gigabytes of disk space. The extra space is used to install computer programs and store your personal data. 80 GB hard drives are commonplace, but 400 GB are available. In addition, you can install more than 1 in a computer for more security and convenience.
Devices
Everything you need to complete the basic computer system is a monitor, a keyboard and mouse. Accessories such as a printer or scanner are useful for office work, and players will probably want to add speakers and joystick control. Thus was done. The basic computer, requires only 7 major components. To obtain the best performance, these components must integrate. The motherboard is the most important component in determining the type and specification of other parties. Choose a mobo for your computer needs is the first step and May require a quick call to your geek. Soon, you will be considered local geek!
