Computer Organization and Architecture Quizzes

Central Processing Unit

Main component of a computer that carries out instructions to run the operating system and applications

Memory

Part of Computer that holds data and instructions for processing is associated with the CPU

John Neumann Architecture

A design model for a stored program digital computer that uses a processing unit

Control Unit

Controls the inside processor which turn the res of PC, that’s why said it was a brain within a brain

Computer Storage

Refers to computer components, devices, and recording medium that retain digital data which used for computing interval time, structure to hold both instructions and data, often called storage or memory.

SSID

A computer architecture in which a single uni-core processor executes a single instruction stream, to operate on data stored in a single memory.

ALU

A part of the CPU where arithmetic and logic operations are performed and sometimes called arithmetic unit

Read-write Memory

A type of computer memory that may be relatively easily written to as well as read from called

DMA

Passes block of data from memory directly to external devices directly to memory

I/O

Allows data and control flags to be passed

Precision

How many digits in the representation, how close the measured values are to each other.

Natural Number

Number theory; in a latter it is preferred in a set of theory and computer science.

Irrational Number

Any real number that is not a rational number

Accuracy

How well does it approximate the real-world value

Integer

Has two infinity number they are negative or positive

Rational Number

Number can be made by dividing one integer by another

Virtual Memory

Bigger physical address space than physical memory that can uses the mass storage disk to get more address

Logical Addressing Space

All the program address space starts at "0" and the program uses consecutive logical addresses. The space available in a single instruction's address field was dictated as the maximum address.

Addressing Memory Segment

Has 16 bit index maximum of 64K segments in a logical program space; 16-bit segment offset 64K bytes per segment maximum

Relocating Code

Symbol tables string into address references that can used by the memory maps address references to actual addresses which it can places data into available addresses at load time and can fixes address references at load time

80×86 Conventions

The top 16 bits or equivalent of 2 bytes is NOT separately addressable and the bottom 16 bits are addressable by old register names.

Boot Loaders

It can be absolute physical addresses and set at COMPILE time

Physical Addressing Space

A single address space hat starts at address 0, its physically contiguous address indices and location contents size like bytes or words

8086 Register

Has both purpose register; the general and special register that available in the assembly language program

Absolute Loaders

It can be absolute physical addresses and set at COMPILE or LOAD time

Cache

Supports random access to main memory locations
