CPU

What is a Processor Descriptive Feature that is a type of CPU architecture with a more complex instruction set than a CPU of RISC architecture

Complex instruction set computer (CISC)

What is a Processor Descriptive Feature that: is executing two or more and is a part of a software program that can be executed independently of the entire program?

Simultaneous Threading

What does CPU stand for?

Central Processing Unit

What converts high-level programming language into assembly language?

A Compiler

What is an Instruction set?

A set of commands the CPUs run

Name the 8 parts of a CPU

ALU Control Unit Decode Unit Data Cache Instruction Cache Input Output Bus Unit (Registers A-F)

Why is the CPU the CENTRAL processing unit?

All other computer components depend on the CPU.

Name the Processor Descriptive Feature that multiplies the speed of the motherboard bus to run the CPU

Clock Doubling

What language is the Instruction Set written in?

Assembly Language-a low-level programming language.

Why is called a unit?

Because it is a self-contained device

Why is it called a processor?

Because it processes data

What is a process of upgrading the CPU that involves: Two cooling styles-Heat Sync/Sink and Fan and Liquid Cooling System?

Cooling the CPU

What is CPU speed

Determines how fast the CPU can process data and commands.

What is a Processor Descriptive Feature that: is a bus architecture with one bus connecting to the main memory and the other to L2 cache.

Dual Independent Bus (DIB)

What is a processor Descriptive Feature that: Describes the enhanced, the Superscaler, and multiple prediction features of the Pentium II?

Dynamic Execution

What are the three CPU performance levels?

High-End Performance (intense graphics, audio, and video) Average Performance (multimedia editing and processing by the average user) Low Performance (introductory PC not designed for graphics and multimedia process)

What enhancements can be made to the CPU Operations? (3)

Improvements to the local Bus Additional Cache Addition of a math coprocessor

Name and describe the 3 Cache types.

L1-Cache contained within the processor that is designed to run at the processor's speed. o L2 Cache mounted outside of the processor. (Note: the Pentium III incorporates the L2 cache in the processor.) o L3 Cache mounted on the motherboard when L1 and L2 caches are incorporated into the CPU.

What is a Processor Descriptive Feature that: is based on a standard processor, has an additional 57 commands, has many new commands that replaced those carried out by the sound and video card, and where L1 cache is larger than that of a standard processor?

MMX processor

What is a Processor Descriptive Feature that; guesses what data element will be needed next; has been proven to be 90% accurate in repetitive tasks, and significantly speeds up CPU operations?

Multiple Branch Prediction

Name the processor Descriptive Feature that: is the process of forcing a CPU to run faster than its approved speed; not supported by manufacturers; excessive heat may develop and may cause CPU damage; and the CPU may also freeze and issue a fatal error message.

Overclocking

What is a Processor Descriptive Feature that: allows you to select the number of CPU cores to apply to a software application?

Processor Affinity

What is a Processor Descriptive Feature that: is a method of controlling processor frequency to conserve battery life and produce less heat; AMD Cool'n Quiet; Intel Precision Cooling; and Enhance Intel SpeedStep

Processor Throttling

What is a Processor Descriptive Feature that is a type of CPU architecture with a fewer number of transistors and commands than a CCPU of CISC architecture?

Reduced Instruction Set Computer (RISC)

What are the typical CPU Operations? (4)

Refresh memory Checking for communication from devices Monitoring system power Performing any other programmed duties

What is a Processor Type where: the CPU is physically packaged in 2 main styles-socket and Single Edge Contact (SEC); and the pattern of pins on the socket style is called a pin grid array (PGA).

Socket and Slot Style

What is CPU power comparisons based on?

Speed and Bus systems.

What is a Processor Descriptive Feature that: was introduced with the Pentium; has the ability to process multiple instructions simultaneously; uses parallel paths called pipelines; and its speed is improved beyond the limits of the clock.

Superscalar

Name the Processor Descriptive Feature that was first developed for laptops, can put a computer in a state of sleep or shut down the computer, is controlled by software, usually set up in the CMOS setup program.

System Management Mode (SMM)

What questions should you ask before upgrading the CPU?

What are you trying to achieve? Will the upgrade fit in the motherboard socket or slot? Will the chipset and BIOS support the upgraded processor? Does the motherboard bus speed, rather than the CPU speed, limit the increase in speed you desire?

What is a Processor type where: Zero Insertion Force (ZIF) sockets have a lever to assist in the installation of the CPU and when the lever is lowered, the ZIF socket clams the CPU pins in place?

Zero Insertion Force (ZIF) Socket

How is CPU speed measured

in Hertz (Hz)
