substantially faster than DRAM chips. SRAM is used mostly for external cache memory.

In composite drivers with two or more physical drives, the drive array sub- system uses a method of data storage called striping. With this method, data is divided into a series of pieces called blocks and each data block is stored on a different physical drive. When each drive contains a block of data, the process starts over with the first physical drive. By carefully selecting the size of the data block, the chance that the information needed can be read from or written to multiple physical drives at once is increased, greatly increasing the perfor- mance of the composite drive. See also block, block size, and RAID.

Sync negotiation is a SCSI feature that allows the host adapter and its attached SCSI devices to transfer data in synchro- nous mode. Synchronous data transfer is faster than asynchronous data transfer.

As the main circuit board, the system board usually contains most of your com- puter’s integral components, such as the following:

‡Microprocessor

‡RAM

‡Expansion-card connectors

‡Controllers for standard peripheral devices, such as the keyboard

‡Various ROM chips

Frequently used synonyms for system board are motherboard and logic board.

System diskette is a synonym forbootable diskette.

V\VWHP￿PHPRU\

System memory is a synonym for RAM.

System Setup program options allow you to configure your computer’s hardware. Some options in the System Setup program require that you reboot the computer in order to make a hardware- configuration change. Because the System Setup program is stored in NVRAM, any options that you set remain in effect until you change them again.

When you start Windows, it consults the system.ini file to determine a variety of options for the Windows operating environment. Among other things, the system.ini file records which video, mouse, and keyboard drivers are installed for Windows.

Running the Control Panel or Windows Setup program may change options in the system.ini file. On other occasions, you may need to change or add options to the system.ini file manually with a text editor, such as Notepad.

Some devices, especially disk drives, con- tain a terminator to absorb and dissipate excess current. When more than one such device is connected in a series, you may need to remove the terminator—or change a jumper setting to disable it— unless it is the last device in the series. However, some devices have terminators that should never be removed or disabled.
