Interrup routine vs subroutine

18:19    No comments

A computer represents a series of interconnected hardware components, all often competing for the same resources and working at a speed of millions of instructions per second. Under these conditions, certain errors occur; components can issue interrupts to signal the computer to hand over control of the system or a part of the system. In these cases, the function of an interrupt service routine or subroutine becomes essential. However, while an ISR may appear to be a simple subroutine, there are slight yet important differences. Interrupt Service...

Q.2 What is BUS? What are the different buses used in CPU?

15:43    No comments

In computer architecture, a bus is a communication system that transfers data between componentsinside acomputer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.Early computer buses were parallel electrical wires with multiple connections, but the term is now used for any physical arrangement that provides the same logical functionality as a parallelelectrical bus. Modern computer buses can use bothparallelandbit serialconnections, and...

Q.1 What is Computer Architecture? What is stored program concept

15:29    No comments

Ans. Computer Architecture: It is concerned with structure and behaviour of computer as seen by the user. It includes the information formats, the instruction set, and techniques for addressing memory of a computer system is concerned with the specifications of the various functional modules, such as processors and memories and structuring them together into a computer system. Stored program concept:- This as introduced in late 1940s by John Von Neumann,Who proposed that a program stored in a binary –number format in a memory device so that instruction...

Q. Which logic name or gates are known as universal logic?

13:12    No comments

Ans. NAND logic and NOR logic gates are universal logic. It is possible to implement any logic expression by NAND and NOR gates. This is because NAND and NOR gates can be used to perform each of Boolean operations INVERT, AND and OR. NAND is same as AND gate symbol except that it has a small circle at output. This a small circle represents the universal operations....

Q. What is shift register in digital computer.

13:08    No comments

Ans. Shift registers are the sequential logic circuit used to shift the data from registers in both directions. Shift registers are designed as a group of flip-flops connected together so that the output from one flip-flop becomes the input to the next flip-flop. The flip-flop are driven by a common clock signals and can be set or reset simultaneously. Shift registers can be connected to form different type of counters....

What its gray code?

13:07    No comments

Gray coding is an important code and is known for its speed. This code is relatively free from the errors. In binary coding or 8421 BCD, counting from 7(0111) to 8(1 000) requires 4-bits to be changed simultaneously. Gray coding avoids this by following only one bit changes between subsequent numbers. ...

Q. What is the concept of layers in architectural design?

11:07    No comments

Ans. The concepts of layers in architectural design are described as below: 1. Complex problems can be segmented into smaller and more manageable form. 2. Each layer is specialized for specific functioning. 3. Upper layers can share the services of a lower layer. Thus layering allows us to reuse functionality. 4. Team development is possible because of logical segmentation. A team of programmers will build. The system and work has to be sub-divided of along clear boundaries....

Q. What is Computer Organisation?

11:01    No comments

Ans. Computer Organisation: It is concerned with the way the hardware components operate and the way they are connected together to form the computer system. The various components are assumed to be in place and the task is to investigate the organisational structure to verify that the computer parts operate. ...

What are the different types of mappings used in cache memory.

10:55    No comments

The three different types of mapping used for the purpose of cache memory are as follow, Associative mapping, Direct mapping and Set-Associative mapping.- Associative mapping: In this type of mapping the associative memory is used to store content and addresses both of the memoryword. This enables the placement of the any word at any place in the cache memory. It is considered to be the fastest and the most flexible mapping form.- Direct mapping: In direct mapping the RAM is made use of to store data and some is stored inthe cache. An address...
