C952 COMPUTER ARCHITECTURE EXTENDED
EXAM WITH QUESTIONS AND ANSWERS
LATEST UPDATE
Moore's Law
states that integrated circuit resources double every 18-24 months
Pipelining
Moves multiple operations through hardware units that each do a piece of an operation.
A means of introducing parallelism into the essentially sequential nature of a machine-
instruction program.
Systems software
provides services that are commonly useful, including operating systems, compilers,
loaders, and assemblers.
Operating System (OS)
Supervising program that manages the resources of a computer for the benefit of the
programs that run on that computer.
,The five classic components of a computer
Input, output, memory, Datapath, and control, with the last two sometimes combined
and called the processor.
liquid crystal display (LCD)
technology using a thin layer of liquid polymers that can be used to transmit or block
light according to whether a charge is applied
Active matrix display
display using a transistor to control the transmission of light at each individual pixel.
Pixel
The smallest individual picture element. Screens are composed of hundreds of
thousands to millions of these, organized in a matrix
Cache memory
small, fast memory that acts as a buffer for the DRAM memory
Static Random Access Memory (SRAM)
Cache is built using this memory technology
Implementation
,Hardware that obeys the architecture abstraction
LAN
A network designed to carry data within a geographically confined area, typically within
a single building
WAN
A network extended over hundreds of kilometers that can span a continent
Transistor
An on/off switch controlled by an electric signal.
VLSI
A circuit containing hundreds of thousands to millions of transistors
Throughput
Another measure of performance, it is the number of tasks completed per unit time
Bandwidth
Another term for throughput
, Raid 0
no redundancy, striping
Raid 1
mirroring, redundancy
Raid 2
error detecting and correcting code, not used
Raid 3
bit interleaved parity
Raid 4
block interleaved parity
Raid 5
distributed block-interleaved parit
Raid 6
P&Q Redundancy
