Computer architecture

Computer architecture is a branch of science which deals with the methodology and rules on the work process of computer hardware and software standards and instructions. It also establishes the relationships between software, hardware and technology infrastructure and their interaction with each other to make a computer work. Operation of computer systems, program operation and platforms are defined by computer architecture. Computer’s design, functionality, and performance are easily explained under this branch. Needs of computer users, process requirements and technology limitations are first determined by the IP professionals. Advanced Computer architecture deals with the organisation, architecture and use of the newest general purpose (micro) processors and the latest research developments in computer architecture.


Q1: What are the contents come under Advanced Computer Architecture?

Q3: What is ALU?

A3: ALU stands for Arithmetic Logic Unit. It is a digital circuit which performs arithmetic and logical operations. The ALU is a fundamental building block of the computer’s central processing unit (CPU).

Q4: What is a schematic symbol of ALU?


schematic symbol of ALU?
schematic symbol of ALU?

Q5: What is a Fixed-point number?

A5: Fixed number of digits after or before the radix point in knows as fixed-point number representation. It is a real data type for a number in computing which can be compared to the more complicated floating point number representation.
