Eight great ideas in computer architecture

What are the roles of computer architecture?

Computer architecture is concerned with balancing the performance, efficiency, cost, and reliability of a computer system. The case of instruction set architecture can be used to illustrate the balance of these competing factors.

What is a role of dependability via redundancy in computer architecture and design?

Dependability via redundancy . Computers not only need to be fast; they need to be dependable . Since any physical device can fail, we make systems dependable by including redundant components that can take over when a failure occurs and to help detect failures.

What is computer architecture and its types?

Introduction to Types of Computer Architecture . Computer architecture consists of rules and methods or procedures which describe the implementation, functionality of the computer systems. We can define computer architecture based on its performance, efficiency, reliability, and cost of the computer system.

What are three aspects of computer architecture?

A modern meaning of the term computer architecture covers three aspects of computer design: – instruction set architecture , – computer organization and – computer hardware.

What are the components of computer architecture?

The different components in the Computer System Architecture are Input Unit , Output Unit, Storage Unit, Arithmetic Logic Unit , Control Unit etc. The input data travels from input unit to ALU . Similarly, the computed data travels from ALU to output unit. The data constantly moves from storage unit to ALU and back again.

What are the five classic components of a computer?

Components of a Computer. The five classic components of a computer are briefly described below. Datapath. The datapath manipulates the data coming through the processor . Control. Control generates control signals that direct the operation of memory and the datapath. Memory . Input . Output . Processor Operation.

What is dependability how it is measured in computer architecture?

Dependability in computer architecture is a measure of a system’s availability, reliability, and its maintainability, and maintenance support performance, and, in some cases, other characteristics such as durability, safety and security.

What are the two main types of chip architecture?

When looked at according to functionality, the four main categories of semiconductors are memory chips , microprocessors, standard chips and complex systems-on-a- chip (SoCs). When organized by types of integrated circuitry, the three types of chips are digital, analog and mixed.

What type of architecture do most computers use today?

Von Neumann architecture

What are the two main elements that make up computer architecture?

Computer architecture is made up of two main components the Instruction Set Architecture (ISA) and the RTL model for the CPU .

What is the difference between computer architecture and computer Organisation?

Computer Architecture is concerned with the way hardware components are connected together to form a computer system. Computer Organization is concerned with the structure and behaviour of a computer system as seen by the user. A programmer can view architecture in terms of instructions, addressing modes and registers.

What is Computer Architecture and Organization?

Introduction. Computer Organization and Architecture is the study of internal working, structuring and implementation of a computer system. Externally visual attributes, here in computer science, mean the way a system is visible to the logic of programs (not the human eyes!).

What are the 4 layers of computer architecture?

The layers of computer architecture are the hardware, operating system, software , and user layers.
