1.How is a monitor’s screen size measured? It is measured diagonally across from one corner to the other.
2.Dot pitch is the distance between a dot and the closest dot of the same color (red, green or blue) on a color CRT.
3.Resolution is the degree of sharpness of a computer generated image measured by the number of dots per linear inch in a hard-copy, or the number of pixels across and down on a screen.
4.A Pixel is the smallest element of an image that can be individually processed.
5.CRT stands for cathode-ray tube. It is a vacuum tube in which a hot cathode emits electrons that are accelerated as a beam through a high voltage positive terminal, focused or deflected electro statically or electromagnetically to allow to show on a screen.
6.LCD means liquid-crystal display. It displays readings continuously on liquid crystal film sealed between glass plates that change optical properties when voltage is applied.
7.Plasma is a translucent greenish type of quartz.
8.DMA is direct memory access. It is a technique of transferring to and from external storage.
9.Solid state is transistor or crystal that can control current without moving parts, heated filaments, or vacuum gaps.
10.Clock cycle is the transition from 0 to 5 volts and back.
11.Serial port is a connector on a computer to which you can attach a serial line connected to peripherals that communicate using a serial protocol.
12.Parallel port is an interface in a computer system where data is transferred on more than one wire.
13.A PC card is a small removable circuit board that houses a device like a disk drive especially for laptops.
14.CD-R means Compact Disk Recordable. You can write information on it but cannot erase or modify it.
15.CD-RW stands for Compact Disk Rewritable. Data can be written multiple times.
16.Duty Cycle is the proportion of time of when a system or device is operated. It can be expressed as a percentage.
17.Kilobytes are about 1000 bytes.
18.Megabytes are about a million bytes.
19.Gigabytes are one billion bytes.
20.Terabytes are one trillion bytes.
21.USB (Universal Serial Bus) is a plug in interface connecting a computer and an add on device.
22.AGP (Accelerated Graphics Port) is an interface that enables 3-D graphics to display faster on ordinary personal computers.
23.System Bus connects the CPU to main memory on the motherboard.
24.PCI (Peripheral Component Interconnect) bus is an interconnection system between a microprocessor and hooked up devices where expansion slots are close for high-speed operation. Intel designed it.
25.ISA (Industry Standard Architecture) bus is a standard interconnection that allows 16 bits at a time to flow between the motherboard circuitry and an expansion slot card and its associated devices.
26.NiCd (Nickel Cadmium) is a type of rechargeable battery used for portable computers.
27.NiMH (Nickel Metal Hydride) are rechargeable lithium batteries.

They are all correct if that is what you are asking.
