Computer Fundamentals and System Concepts

The Central Processing Unit (CPU) is often referred to as the brain or heart of the computer because it performs the primary calculations and logic operations.

Fourth generation computers mainly used in VLSI and LSI technology,  VSI -Large scale Integrated circuits and VLSI - Very large scale integrated circuits.

All the above answers are incorrect. The sequence of microinstruction is called microprogam.

Data lines provide path for moving data between data system modules called as data bus. Example - 32 bit path data bus is viewed as a collection of wires.

A computer network is a telecommunications network, which allows computers to exchange information. It is a group of two or more computer systems linked together.

A process is an instance of a computer program that is being executed. It contains the program code and its current activity.

A loader which combines the functions of a relocating loader with the ability to combine a number of program segments that have been independently compiled into an executable program.

A virus protection software is designed to prevent viruses, worms and trojan horses from getting into a computer as well as remove any malicious software code.

It is a software that manages all the system resources to provide services that allows various applications to be executed.

It is a tool for the systematic evaluation of the environmental aspects of a product through all stages of its life cycle.

The Start menu in Windows provides a centralized location to access installed applications, system settings, and frequently used files.

The ILLIAC series (e.g., ILLIAC IV) were pioneering supercomputers developed at the University of Illinois.

An opcode (operation code) is the portion of a machine language instruction that specifies the operation to be performed by the CPU. The address field specifies the data or location to be operated on.

Euronet was an early packet-switched network established in Europe during the 1970s. The other options (Ring, LAN, Star) describe network topologies or types, not specific packet-switching networks.

Data integrity refers to the maintenance and assurance of data accuracy and consistency over its entire life cycle, including protection against system errors or unauthorized changes.
