Peripherals

Peripherals are devices attached to the computer via I/O ports. Peripheral devices

allow your computer to perform an almost limitless variety of specialized tasks.

Plug and Play BIOS

The ISA bus architecture requires the allocation of memory and I/O address, DMA

channels and interrupt levels among multiple ISA cards. However, configuration of

ISA cards is typically done with jumpers that change the decode maps for memory

and I/O space and steer the DMA and interrupt signals to different pins on the bus.

Further, system configuration files may need to be updated to reflect these changes.

Users typically resolve sharing conflicts by referring to documentation provided by

each manufacturer. For the average user, this configuration process can be unreli-

able and frustrating. Plug and play (PnP) BIOS eliminates the ISA add-on card hard-

ware conflict problem. The PnP BIOS uses a memory block to define and remember

each card's configuration, which allows the user to change the card's IRQs and DMA

in BIOS either automatically or manually.

POST (Power On Self Test)

When you turn ON the computer, it will first run through the POST, a series of

software-controlled diagnostic tests. The POST checks system memory, the mother-

board circuitry, the display, the keyboard, the diskette drive, and other I/O devices.

PS/2 Port

PS/2 ports are based on IBM Micro Channel Architecture. This type of architecture

transfers data through a 16-bit or 32-bit bus. A PS/2 mouse and/or keyboard may be

used on ATX motherboards.

RAM (Random Access Memory)

There are several different types of RAM such as DRAM (Dynamic RAM), EDO

DRAM (Extended Data Output DRAM), SDRAM (Synchronous DRAM).

ROM (Read Only Memory)

ROM is nonvolatile memory used to store permanent programs (called firmware)

used in certain computer components. Flash ROM (or EEPROM) can be repro-

grammed with new programs (or BIOS).

SCSI (Small Computer System Interface)

High speed multi-threaded I/O interface defined by the X3T9.2 committee of the

American National Standards Institute (ANSI) for connecting many peripheral de-

vices. The standard started from 10MBytes/sec to 160MBytes/sec available today.

SDRAM (Synchronous DRAM)

The SDRAM features a fully synchronous operation referenced to a positive edge

clock whereby all operations are synchronized at a clock input which enables the

coexistence of high performance and a simple user interface. SDRAM takes memory

access away from the CPU's control; internal registers in the chips accept the re-

quest, and let the CPU do something else while the data requested is assembled for

the next time the CPU talks to the memory. As they work on their own clock cycle,

the rest of the system can be clocked faster. There is a version optimized for video

cards, and main memory for motherboards.
