Study Notes
Computer System Expansion Slots
- Expansion slots connect an expansion bus to the processor, allowing communication with peripheral devices attached to the adapter card.
- Data is transmitted to the memory or processor through the expansion slot, expansion bus, and system bus.
ISA Slot
- Industry Standard Architecture (ISA) is an 8-bit and 16-bit wide bus that runs at 4.77 MHz.
- Developed by Mark Dean at IBM as part of the IBM PC project in 1981.
- Originated as an 8-bit system and was extended in 1983 for the XT system architecture.
- The 16-bit standard, the IBM AT bus, was introduced in 1984.
PCI Slot
- Peripheral Component Interconnect (PCI) is a 32-bit data bus interface.
- Widely used by expansion card manufacturers.
AGP Slot
- Accelerated Graphics Port (AGP) is a high-speed point-to-point channel for attaching a graphics card to a computer's motherboard.
- Primarily used for accelerating 3D computer graphics.
- AGP controller can only control a single device.
AMR Slot
- Audio Modem Riser (AMR) is a riser card that supports sound or modem function.
ACR Slot
- Advance Communication Riser (ACR) is a slot for communication and audio subsystem.
CPU Sockets or Slots
- CPU sockets are single-edged connectors similar to expansion slots.
- Slotted CPU packages offered two advantages: L2 cache memory size could be packaged with the CPU, and processor insertion and removal was easier.
- Land grid array (LGA) packages have started to supplant PGA with most modern CPU designs.
Memory Socket or Slot
- Memory sockets or slots are commonly referred to as the slot in a motherboard where extended memory modules are installed.
- Types of memory sockets or slots include SIMM, DIMM, SDR, DDR, and SODIMM.
CMOS Technology
- Complementary metal-oxide-semiconductor (CMOS) technology is used for a wide variety of analog circuits.
- Frank Wanlass successfully patented CMOS in 1967 (US Patent 3,356,858).
Chipset
- A chipset refers to a group of chips on the motherboard, including the NORTHBRIDGE and the SOUTHBRIDGE.
- The chipset links the CPU to various devices, especially main memory.
- The southbridge connects to lower-speed peripheral buses (such as PCI or ISA).
- Chipsets are usually designed to work with a specific family of microprocessors.
- The chipset plays a crucial role in determining system performance.
