MODULE 5 - 6 Flashcards
The CPU is housed in a single chip called
Microprocessor
A component of CPU which performs arithmetic and logical operations
ALU
A component of CPU which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
CU
Uses more advanced architectures for their processors at the moment.
INTEL
Focuses more on including more cores, making budget
friendly CPUs, and allowing users to overclock heavily.
AMD
is AMD CPUs where the pins are on the CPU. It has larger pins
and allows for higher voltages and stability.
PGA
Is Intel chips where the pins are in the motherboard socket. It has
smaller pins thus allows for higher and faster current.
LGA
Required only 60 lbs. of insertion force for a 169-pin chip.
LIF
This sockets are handle-actuated:
ZIF
The original OverDrive socket, is
a 169-pin PGA socket.
Socket 1
Called the Pentium
OverDrive processor, adds a special active heatsink to solve the problem of the chip ran too hot for many systems
Socket 2
Is the most flexible upgradeable 486
design. Provides for better keying.
Socket 3
is a 273-pin socket designed for the original Intel Pentium processors.
Socket 4
has the 320 pins
configured in a staggered PGA, in
which the individual pins are
staggered for tighter clearance.
Socket 5
has 235 pins and accepts only 3.3V 486 or OverDrive processors.
Socket 6
same as Socket 5 with one additional key pin therefore, has 321 pins total
Socket 7
A special SPGA socket featuring
whopping 387 pins.
Socket 8
was originally designed to directly
compete in the lower-end system market along with the Super7
platform supported by AMD and Cyrix.
Socket 370 or PGA-370
A ZIF type socket that uses a
unique heatsink mounting method that requires standoffs attached either to the chassis or to a special plate that mounts underneath the
motherboard.
Socket 423
A ZIF type socket that was specially designed to support additional pins for future Pentium 4 processors and speeds over 2GHz
Socket 478 or Socket N
Also called Socket 462 that has
the same physical dimensions and
layout as Socket 370
Socket A
is used with the
Intel Xeon processor in DP
(dual processor) and MP
(multiple processor)
configurations.
Socket 603
is used with the initial
releases of the AMD Athlon 64
processors.
Socket 754
Have different pin arrangements and processors for each and are
not interchangeable.
Socket 939 and 940
The easiest way to categorize memory
Form Factor
memory chips are soldered onto
a modular printed circuit board (PCB), which inserts into a socket
on the system board.
SIMM
closely resemble SIMMs, it is install vertically into expansion
sockets.
DIMM
A type of memory commonly used in notebook computers
SO DIMM
is the trademarked name for a Direct Rambus memory
module. Look similar to DIMMs, but have a different pin count.
RIMM
looks similar to an SO DIMM, but it uses Rambus technology.
SO RIMM
is a solid-state, non-volatile, rewritable memory that functions like RAM and a hard disk drive combined. Also works
like a hard-disk drive in that when the power is turned off, the
data remains in memory.
Flash Memory
uses multiple transistors, is used primarily for cache.
SRAM
It has memory cells with a paired transistor and
capacitor requiring constant refreshing.
DRAM
It was the most common form of DRAM found in computers. It enabled faster access to data located within the same row.
FPM
enabled the CPU to access memory 10 to 15% faster than with FPM.
EDO
is designed to synchronize itself with the timing of the CPU.
SDRAM
Is a next-generation SDRAM technology. It allows
the memory chip to perform transactions on both the rising and
falling edges of the clock cycle.
DDR SDRAM
Has two ports instead of one, which allows the memory to allocate one
channel to refreshing the screen while the other is focused on
changing the images on the screen.
VRAM
Its dedicated display port is smaller and it supports EDO features.
WRAM
is a video-specific extension of SDRAM that allows data to be
retrieved and modified in blocks, instead of individually.
SGRAM
Before it even became a contender for main memory, it was actually used in video memory.
Rambus Technology
also known as firmware
ROM
can only be programmed once.
PROM
requires a special tool that emits a certain frequency of ultraviolet (UV) light.
EPROM
