Computer Fundamentals and System Concepts

It is the soul of the computer. Accessing software includes running, executing, opening and others. It is stored in files.

Computers and laptops do not have this kind of command keys.

Unsigned integers use all bits for magnitude (no sign bit), giving them a larger positive range than signed integers of the same bit width. They cannot represent negative values, unlike signed integers.

In computing, 'platform' refers to the combination of computer hardware architecture and the operating system that runs on it. For example, 'Windows platform' or 'Mac platform' encompasses both the hardware (Intel/AMD processors, ARM chips) and the operating system. Software is often described as being 'cross-platform' when it can run on different hardware-OS combinations, demonstrating that platform includes both elements.

Software consists of programs and instructions that can manipulate and control computers; this is its defining characteristic. Unlike hardware components, software is intangible code that cannot be physically touched. The other options describe actual software properties.

A workstation is a single-user computer designed for technical or scientific applications, featuring robust processing power, advanced graphics, and specialized capabilities. Minicomputers support multiple users simultaneously. Macintosh is one brand of workstation. The question describes the workstation category perfectly.

Shared disks are accessible from any of the processors through the communication network.

EKA, developed by Computational Research Laboratories (CRL) in Pune, India, was ranked as the fourth fastest supercomputer in the world in the Top 500 listing. This was a significant achievement for India's computational capabilities. The other options (HPC, TKA, SKC) are not the names of supercomputers that achieved this specific ranking from CRL.

Pastry is a food term (baked dough), unrelated to computers. RAM (Random Access Memory), Mouse (input device), and Byte (unit of digital information) are all fundamental computer terms.

This is the correct answer.

Control Unit controls all the operations and hence, is known as the nervous system of the computer.

Microprocessor is the right answer. It has square shape. It has 30 pins. The main function of the microprocessor is to control Input/Output and Memory Unit.

It is responsible for overall functions of the computer. It tells us that which computer program and instructions are executed and coordinates the activity of the computer.
