Main computer components.
Processor (CPU): The processor in a computer refers to the part of a computer system which carries out the computer program's instructions, to perform the basic arithmetical, logical as well as input and output operations of the system. It plays a role somewhat similar to that of a brain in the computer. It executes as well as interprets programs, and processes data. It is the main function of any computer, and without it the computer itself would be a lost source.
RAM (Random Access Memory)
Often confused with the hard drive, RAM stands for Random Access Memory and is the most common type of memory used in computers. A computer's RAM is the memory used to store data and programs on a temporary basis. The RAM is compared to short-term memory, as it stores applications and information that is actively used while the system is on. In comparison, the hard drive, the long-term memory, stores all programs and ...view middle of the document...
That’s the sad truth. Which is why most people have a backup system. They get another hard drive and copy all their important files onto that.
Graphics card and sound card: A graphics card is a computer's data-to-image translator. It takes the binary data from the central processing unit (CPU) and turns it into a screen image. The CPU works with software to send data about the desired image to the graphics card. The graphics card is responsible for working out the details of exactly how the pixels on the computer's monitor will create that image. After it does that, it sends the image through a cable to the computer's monitor
Motherboard Motherboards or Main Boards is the primary source that links your computer processor unit (CPU), your memory, and hardware. Think of the motherboard as the veins of the computer. The CPU is the brain. The brain (CPU) computes data thru the veins (motherboard) from your hard drives (storage). The motherboard is also responsible for holding the settings of your computer such as: Time and Date, the type and placement of your hard drive, CR-Rom and so on
| An optical drive is merely a CD or DVD drive. An optical drive uses disc and lasers to store and retrieve data. Your CD/DVD on your computer is an optical drive. So is the DVD player |
monitor or a display is an electronic visual display for computers. The monitor comprises the display device, circuitry and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display thin panel, while older monitors use a cathode ray tube about as deep as the screen size.
The power supply takes power from the power system of an office or home and converts it into a form that the personal computer can use. It is required to provide various voltages, at different strengths, since the various components found in the computer's system unit have different power requirements.
Network Card: A network card prepares, sends, and controls data on the network. It acts as connector between a computer and a network cable. It is also called a network adapter or network interface card. It is exhibits settings that are configured to ensure that the computer and network are compatible.
