A term you want not listed? Everything inside the computer is connected to a circuit board called the ' motherboard '. You may also find a modem inside on an add-on card. Older Intel CPU's include the and families. Other manufacturers also make CPU's: The 'speed' of a CPU's processing is measured in megahertz.
It is not permanent memory - the RAM is erased when the computer turns off. Permanent memory is stored on the hard drive. Memory is measured in increments of bits and bytes.
Generally the least memory you should ever have with a Pentium computer is 64 MB megabytes: Don't confuse this with ROM. This is an add-in or expansion board such as a video card, sound card or modem.
On every motherboard there are places to add circuit boards to extend the capabilities of the computer. There are various types of expansion slots that may be on the motherboard. The ISA Industry Standards Association expansion slot is the older type and most of the older circuit boards used this type of slot.
A more sophisticated type of slot is the PCI and the newer modems, and more sophisticated sound cards require this type of slot. The AGP port enables high performance graphics capabilities, especially for 3D graphics.
The video card controls what you see on the monitor. It determines how many dots across the screen and down the screen the computer can look after.
The more dots, the more information or the more detail you can see. The video card also controls how many colors you can see. Most computers today can show anywhere from colors to many millions of colors.
The sound card controls the sound. Most computers come with pretty cheap speakers, and the sound card can probably produce much better sound than the speakers can. With good speakers, today's sound cards can make your computer sound as good as a stereo! The hard drive uses disks that are made of aluminum or glass and therefore 'hard'.
Sometimes, there may be several disks in a hard drive. However, the disks in a normal hard drive can not be removed or replaced. Today, hard drives are measured in gigabytes.
That's one thousand million bytes. Sometimes a special cache is used for quick retrieval of often-used information such as web pages.
This is just a separate directory on the hard drive. Generally when we talk about a floppy disk drive we are talking about the drive that uses the 3. At one time there was the PC keyboardthe AT keyboard, and the key enhanced keyboard, which had F9 through F12 keys and a separate numeric keypad.
Now the key enhanced keyboard is the standard type and keyboards are named according to the type of connection it makes to the computer. There are a lot of varieties of mice in use today.
There are also programmable mice, touch pads that substitute for a mouse, etc. A modem allows your computer to connect to another computer using the normal telephone line. It converts data from a computer format, which requires many wires, into a format that can be sent using only the two wires of a telephone line.
At the other end of the telephone wires the process is reversed.TigerDirect Business is your one-stop-shop for everything related to computers and electronics.
