Computer Fundamentals and System Concepts

PARAM is a series of supercomputers designed and assembled by the Centre for Development of Advanced Computing (C-DAC) in India. The first in the series, PARAM 8000, was launched in 1991.

Norton Utilities and PC Tools are classic examples of utility software used for system maintenance and optimization. Since all listed options are utilities, 'None of these' is the correct answer to which is NOT a utility.

Liveware is a term used to refer to the human element in a computer system. It distinguishes the people who operate and maintain the system from the hardware and software components.

Windows is an operating system, which is a type of software that manages the computer. Hardware refers to physical components like the monitor, keyboard, CPU, and mouse.

File extensions are the suffixes at the end of a filename (like .doc or .htm) that tell the operating system which program should be used to open the file. They define the format of the data within the file.

A memory dump or system dump is a recorded copy of the contents of computer memory or workspace associated with a process at a specific time, often used for debugging.

Electronic filing (misspelled as 'filling' in the options) refers to the digital storage and management of documents, allowing for easy organization and retrieval. It replaces traditional paper-based filing systems.

A digital computer is fundamentally composed of input devices, output devices, and the Central Processing Unit (CPU). The CPU itself contains the ALU and Control Unit, making it the primary third functional element.

Microprocessors of the 1970s, such as the Intel 8080, typically featured an 8-bit data bus for processing data and a 16-bit address bus to access up to 64KB of memory. This architecture was the foundation for the first generation of personal computers.

A multi-user system is designed to support multiple users simultaneously by sharing the CPU's time and resources. This requires the operating system and hardware to handle multiple processing tasks concurrently through techniques like time-sharing.

A device driver is a specialized software component that allows the operating system to communicate with and control a specific hardware device. It manages the low-level timing and operational commands required for the hardware to function correctly within the system.

In a distributed network, the host computer acts as the central server that manages resources, provides data, and controls the operations of connected terminals or smaller processors. It typically has more processing power and storage than the devices it serves.

A parallel computer is specifically designed to perform multiple operations or process multiple data streams simultaneously. This architecture contrasts with serial processing, where instructions are executed one after another.

Execution states refer to the distinct modes or conditions, such as user mode or kernel mode, in which a processor can operate. These states define the privileges and instructions available to the system at any given time.
