Vocab Tech In Focus 3 Flashcards
Arithmetic logic unit (ALU)
.is the part of the COU designed to perform mathematical operations
Test comparisons of greater than, less than, and equal to
ARM processor
Is used in wearables, tablets, and smartphones, was a CPU contender that challenged Intel for supremacy in the market
ASCII
.can assign only 256 codes and cannot represent all languages
Binary number system
.computers describe a number in powers of 2 Bc each switch can be in one of two positions on or off
Bit
A digit hat corresponds to the on and off states of a computers switches . A bit contains a value of 0 or 1
Cache
.small blocks of memory, located directly in and best to the central processing unit CPU that act as holding places for recently or frequently used instructions or data that the CPU accesses the most
Quicker than RAM
Control unit
.to translate or decode the programs instructions into commands the CPU can understand
Decimal number system
.are stored according to the IEEE floating- point standard
Can. Be represented by the binary system
Decode
.once the programs binary code is in the CPU . It is decided into commands the CPU understands
Execute
The CPU actually performs the work described in the commands. Specialized hardware on the CPU performs addition, etc and all mathematical operations
Fetch
.when any program begins to run the 1s and 0s that make up the programs.m binary code must be fetched form Temp.
Ram to CPU
Floating-point
.describes how numbers with fractional parts should be represented in the binary number system.
Hexadecimal number system
.base 16 number system instead of 10
Integrated circuit
.tiny regions of semiconductor material that support huge number of transistors .
Released in 1971
True miniaturization of computers
Machine language
.he machine language of a CPU ; the sequence of bits that the CPU understands
