3. USB

4. audio

5. video

6. LAN

7. PCI

In electronics, you can think of a bus as an _.
electronic highway on which data travels

1. Arithmetic Unit

2. Control Unit

The Arithmetic Unit performs _, and the Control Unit _.

1. math and logical operations

2. decodes instructions

PGA stands for

Pin Grid Array

PGA is _.

A processor package that is usually square with pins underneath that fit into holes on the CPU's slot.

LGA stands for

Land Grid Array

LGA is _.

When the pins are located on the slots themselves

Socket Type: LGA 771 (Socket J)

Manufacturer: Intel (Xeon Server)

Socket Type: LGA 775 (Socket T)

Manufacturer: Intel

Manufacturer: AMD
AM2+ and AM3 mainly differ in terms of the _ each supports. AM2+ supports _ while AM3 supports _.

1. memory

2. DDR2

3. DDR2 and DDR3

Each processor is specific to a _.


AM3 is an example of a _.

AMD processor

LGA 775 (Socket T) is an example of a _.

Intel processor

Speed is measured in _.
Gigahertz (GHz)
Because the CPU greatly determines the overall performance of a PC, the _ and _ are two of the main factors to look for when deciding to buy a computer.

1. type of processor

2. it's speed

How do you find the CPU speed for a given motherboard?

CPUs contain a multiplier that when multiplied by the bus speed, yields the appropriate CPU speed for a given motherboard. For example, if the speed of a motherboard is 800 MHz, and the CPU multiplier is 4, then the processor's speed is 800 x 4 = 3200 MHz or 3.2 GHz.
CPUs are either _ or _.
32-bit or 64-bit.

What does 32-bit or 64-bit mean?

How much data that can be processed in terms of bits.

A bit is _.

In computers data is composed of 1's and 0's (e.g. 01110010). A bit is either a 0 or a 1.

CPU cache is _.
Memory set aside for the most frequently used data
The types of CPU caches are:
Level 1, Level 2, and Level 3 (commonly just called L1, L2, and L3).

An L1 cache (3):

1. Uses extremely fast and expensive SRAM (Static RAM)

2. Is the smallest in size

3. Is located on the processor

An L2 cache (1):

1. Is slightly larger than an L1 cache

An L3 cache:

1. Is the largest

2. Usually located outside of the CPU

3. Shared by alll the cores

Dual core and multicore are generic for _.
Any processor that literally contains two or more CPUs in one package.
AMD's Athlon x2, Turion x2, and Intel's Core 2 Duo and Core 2 Extreme are examples of _.

Dual core CPUs

AMD Phenom x3 and x4 and Intel's Core 2 Quad and the Core i7 are examples of _.

Multicore CPUs

RAM stands for:

Random Access Memory
