Domain 4.0: Motherboards / Processors / Memory
This domain requires knowledge of
specific terminology, facts, ways and means of dealing with classifications,
categories and principles of motherboards, processors in memory in microcomputer
systems:
4.1 Distinguish between popular CPU
chips in terms of their basic characteristics:
- Popular CPU chips (Intel, AMD, Cyrix)
- Characteristics
- Physical size
- Voltage
- Speeds
- On board cache or not
- Sockets
- (SEC) single edge contact
4.2 Identify the categories of RAM
(random access memory) terminology, their locations, and physical characteristics:
- Terminology:
- EDO RAM (extended data output RAM)
- DRAM (dynamic random access memory)
- SRAM (static RAM)
- RIMM (Rambus in-line memory module 184 pins)
- VRAM (video RAM)
- SDRAM (synchronous dynamic RAM)
- WRAM (Windows accelerator card RAM)
- Locations and physical characteristics:
- Memory bank
- Memory chips (8-bit, 16-bit, and 32-bit)
- SIMMS (Single in-line memory module)
- DIMMS (dual in-line memory module)
- Parity chips vs. non-parity chips
4.5 Identify the most popular types
of motherboards, the components and architecture (bus structures and
power supplies):
- Types of motherboards:
- Components:
- Communications ports
- SIMM and DIMM
- Processor sockets
- External cache memory (level 2)
- Bus architectures:
- ISA
- PCI
- AGP
- USB (Universal serial bus)
- VESA local bus (VL-bus)
- Basic compatibility guidelines:
- IDE (ATA, ATAPI, ULTRA- DMA, EIDE)
- SCSI (wide, fast, ultra, LVD (Low Voltage Differential)
4.4 Identify the purpose of CMOS
(complementary metal-oxide semiconductor), what it contains and how
to change its basic parameters:
- Printer parallel port - Uni, bi-directional,
disabled/enable, ECP, EPP
- Com/serial port-memory address, interrupt request,
disable
- Floppy Drive-enable/disable drive or boot, speed,
density
- Hard drive- size and drive type
- Memory-parity, non-party
- Boot sequence
- Date/Time
- Passwords
- Plug & play BIOS
