The two leading manufacturers of personal computer processor chips are
Intel and AMD
Parts inside of a desktop
Power supply and fan; video card; sound card; processor; heat sink and fan; memory module
Processor
aka CPU; interprets and carries our the basic instructions that operate a computer.
Access time
amount of time it takes the processor to read from memory
Gordon Moore
cofounded Intel
control unit
component of the processor that directs and coordinates most of the operations in the computer
nonvolatile memory
does not lose contents when power is removed; MRAM (used for industrial) ROM, flash memory, and CMOS
PCI express bus
type of expansion bus; newest video cards today
Processor chip
generates heat that could cause the chip to malfunction or fail
memory size is measured in
gigabytes or terabytes
Require additional cooling
heat sinks; liquid cooling technology; cooling mats
The system unit contains two types of memory
volatile memory and nonvolatile memory
volatile memory
loses its contents when power is turned off; DRAM(dynamic ram);
Motherboard
main circuit board of the computer
2 GHz
means 2 billion ticks per second; about average
Each location in ________ has an address
memory
Access time is measured in
nanoseconds
Two cleaning mistakes
never use a vacuum cleaner when cleaning a computer b/c static electricity; if using compressed air can, bend straw and keep bottle up right
nanosecond
one-billionth of a second
Clock speed
pace of the system clock; measured in gigahertz (GHz)
arithmetic unit
performs arithmetic, comparison, and other operations
The processor contains...
registers, that temporarily hold data and instructions
Multi-core processor
single chip with two or more separate processor cores
A supercomputer would have a
terabyte
Lower cost/lower power
Core I5 and Sempron
Laptop processor
Core I5 and Turion
Mainstream
Core I7 and Phenom II
Low end servers on a network
Xeon and opteron
Processors contain
a control unit and an arithmetic unit (ALU)
Computer chip
contains integrated circuits
System clock
controls the timing of all computer operations
