The ISP typically provides you with a software package, user name, and access phone numbers for a fee. A measurement of the capacity of memory integrated circuits. A LAN usually is confined to a building or a few nearby buildings. A LAN can be connected to another LAN over any distance through telephone lines and radio waves to form a wide area network (WAN). This measurement is typically used for transmission speeds for networks and modems. When used to refer to hard drive storage, the term is often rounded to 1,000,000 bytes. This measurement is typically used for data transfer ratings. Because the data in memory is not permanent, it is recommended that you frequently save your files while you are working on them, and always save your files before you shut down the computer. Your computer can contain several different forms of memory, such as RAM, ROM, and video memory. Frequently, the word memory is used as a synonym for RAM. Devices and software can then identify information that the processor can access. The speeds for computer processors, buses, and interfaces are often measured in MHz. Also known as WWAN. Three types of modems include: external, PC Card, and internal. You typically use your modem to connect to the Internet and exchange e-mail. Typically you roll the mouse over a hard, flat surface to move the pointer or cursor on your screen. Access times of storage devices are often measured in ms. A computer may include a network adapter on its system board, or it may contain a PC Card with an adapter on it. A network adapter is also referred to as a NIC (network interface controller). Also referred to as system tray. NVRAM is used for maintaining computer configuration information such as date, time, and other system setup options that you can set. Each partition can contain multiple logical drives. Modems and network adapters are common types of PC Cards. If the PCI Express chip set and the device are capable of different speeds, they will operate at the slower speed. Pixels are arranged in rows and columns to create an image. A video resolution, such as 800 x 600, is expressed as the number of pixels across by the number of pixels up and down. Plug and Play provides automatic installation, configuration, and compatibility with existing hardware if the BIOS, operating system, and all devices are Plug and Play compliant. If no problems are detected during POST, the computer continues the start-up. Sometimes the processor is referred to as the CPU (central processing unit). Programs require an operating system to run. Some common implementations of RAID include RAID 0, RAID 1, RAID 5, RAID 10, and RAID 50. Any information stored in RAM is lost when you shut down your computer. Typically, readme files provide installation information and describe new product enhancements or corrections that have not yet been documented. A file can have read-only status if: The higher the refresh rate, the less video flicker can be seen by the human eye. The higher the resolution, the sharper the image. Radio frequencies are at the lower end of the electromagnetic frequency spectrum and are more likely to have interference than the higher frequency radiations, such as infrared and light. ROM, unlike RAM, retains its contents after you shut down your computer. Some programs essential to the operation of your computer reside in ROM. Hard drive speed is often measured in rpm. ScanDisk often runs when you restart the computer after it has stopped responding. Setup program differs from system setup. When you place a shortcut on your Windows desktop and double-click the icon, you can open its corresponding folder or file without having to find it first.

Devices are plugged directly in to a 4-pin socket on your computer or in to a multi-port hub that plugs in to your computer. USB devices can be connected and disconnected while the computer is turned on, and they can also be daisy-chained together. Pairs of unshielded wires are twisted to protect against electromagnetic interference, rather than relying on a metal sheath around each pair of wires to protect against interference. Video memory is usually faster than system memory. The amount of video memory installed primarily influences the number of colors that a program can display. Graphics-based software, such as Windows operating systems, displays in video modes that can be defined as x horizontal pixels by y vertical pixels by z colors. Character-based software, such as text editors, displays in video modes that can be defined as x columns by y rows of characters. A virus program moves from one computer to another through an infected disk, software downloaded from the Internet, or e-mail attachments. When an infected program starts, its embedded virus also starts. If the floppy disk is left in the drive when the computer is shut down and then turned on, the computer is infected when it reads the boot sectors of the floppy disk expecting to find the operating system. If the computer is infected, the boot virus may replicate itself onto all the floppy disks that are read or written in that computer until the virus is eradicated. One V appears across a resistance of 1 ohm when a current of 1 ampere flows through that resistance. One W is 1 ampere of current flowing at 1 volt. For example, a 66-WHr battery can supply 66 W of power for 1 hour or 33 W for 2 hours. Change your wallpaper through the Windows Control Panel. You can also scan in your favorite picture and make it wallpaper. A series of interconnected computers that communicate with each other over the air waves using access points or wireless routers to provide Internet access.
