CMSC 306 Module 1 Quiz

Computer architecture refers to those attributes of a system visible to a programmer or, put another way, those attributes that have a direct impact on the logical execution of a program.

• TRUE

• FALSE

A term that is often used interchangeably with computer architecture is instruction set architecture (ISA). The ISA defines instruction formats, instruction opcodes, registers, instruction and data memory; the effect of executed instructions on the registers and memory; and an algorithm for controlling instruction execution.

• 1. 1^st and 2^nd statement are true

• 1. 1^st statement is true and the 2^nd statement is false.

• 1. 1^st and 2^nd statement are false

• 1. 1^st statement is false and the 2^nd statement is true.

Computer organization refers to the operational units and their interconnections that realize the architectural specifications. Examples of architectural attributes include the instruction set, the number of bits used to represent various data types (e.g., numbers, characters), I/O mechanisms, and techniques for addressing memory

• 1. 1^st and 2^nd statement are true

• 1. 1^st statement is true and the 2^nd statement is false.

• 1. 1^st and 2^nd statement are false

• 1. 1^st statement is false and the 2^nd statement is true.

Function is the way in which the components are interrelated. Structure is the operation of each individual component as part of the function.

• 1. 1^st and 2^nd statement are true

• 1. 1^st statement is true and the 2^nd statement is false.

• 1. 1^st and 2^nd statement are false

• 1. 1^st statement is false and the 2^nd statement is true.

Both the structure and functioning of a computer are, in essence, simple. In general terms, there are only four basic functions that a computer can perform which are data processing, data storage, data movement and data encryption.

• 1. 1^st and 2^nd statement are true

• 1. 1^st statement is true and the 2^nd statement is false.

• 1. 1^st and 2^nd statement are false

• 1. 1^st statement is false and the 2^nd statement is true.

It controls the operation of the computer and performs its data processing functions; often simply referred to as processor

• I/O

• Main memory

• Central processing unit (CPU)

• System interconnection

Performs the computer’s data processing functions.

• Control unit

• Arithmetic and logic unit (ALU)

• Registers

• CPU interconnection

A physical piece of silicon containing one or more cores. The processor is the computer component that interprets and executes instructions. If a processor contains multiple cores, it is referred to as a multicore processor

• Central processing unit (CPU)

• Core

• Processor

• Cache memory

includes the tasks involved in fetching instructions, and decoding each instruction to determine the instruction operation and the memory locations of any operands.

• Instruction Logic

• Arithmetic and Logic Unit (ALU)

• Load/store logic

The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). These tubes, like electric bulbs, produced a lot of heat and were prone to frequent fusing of the installations, therefore, were very expensive and could be afforded only by very large organizations.

• 1. 1^st and 2^nd statement are true

• 1. 1^st statement is true and the 2^nd statement is false.

• 1. 1^st and 2^nd statement are false

• 1. 1^st statement is false and the 2^nd statement is true.
