Clock Frequency

The number of commands per second a device can process (also known

as hertz [Hz]). The higher the clock frequency the faster the device is.

Often used in conjunction with the processor speed: A Pentium running

at 200 MHz (Megahertz) is slower than a Pentium running at 400 MHz.

CMOS

Short for "Complementary Metal Oxide Semiconductor". CMOS is a

manufacturing method that only requires a small current and does not

generate much heat. Most PC clocks use a battery based CMOS chip.

Color depth

The number of distinct colors that can be represented by a piece of

hardware or software. Color depth is sometimes referred to as bit depth

because it is directly related to the number of bits used for each pixel. A

24-bit video adapter, for example, has a color depth of 2 to the 24th

power (about 16.7 million) colors. One would say that its color depth is

24 bits.

A cookie is a piece of information stored by a web site on your

computer which that particular web site can read. This is useful for

some advanced surfing features such as shopping or logging in.

CPU

Short for "Central Processing Unit", also known as the processor.
