Computer Science

The time taken by a computer to process a job or instruction is called Execution Time, which measures the actual time the CPU spends executing the instruction. Waiting Time and Delay Time refer to time spent waiting, and Real Time refers to systems responding within a time constraint, not processing time.

An intelligent agent is software that can perform tasks autonomously or semi-autonomously on behalf of a user, especially repetitive or decision-based tasks. Fuzzy logic and genetic algorithms are AI techniques, not software agents that perform user tasks directly.

Application software is designed to help users perform specific tasks such as word processing, browsing the internet, or managing data. It is distinct from system software, which manages hardware and runs the operating system.

PUBG is a video game, which is a type of entertainment software designed for user enjoyment. Google Docs is productivity software, Windows OS is an operating system, and WinRAR is a file compression utility, none of which are primarily for entertainment.

Oracle is a technology company known for database software and cloud services, not antivirus software. McAfee, AVG, and Avira are all well-known antivirus software providers.

Microsoft Word is a widely used word processing software designed for creating, editing, and formatting text documents. The other options are not word processors: Adobe Photoshop is for image editing, VLC Media Player is for playing media files, and Google Chrome is a web browser.

MS Office, Adobe Photoshop, and Windows OS are commercial products developed and sold by companies, making them proprietary software. They are not open-source, freeware, or shareware.

An operating system is a collection of system programs that manages and coordinates the overall operations of a computer system, including hardware and software resources. It acts as an intermediary between users and the computer hardware.

Linux, Apache, and Mozilla Firefox are all examples of open-source software because their source code is freely available for anyone to view, modify, and distribute. This distinguishes them from freeware, proprietary, or public domain software.

CAD stands for Computer Aided Design, which refers to the use of computer software to assist in the creation, modification, analysis, or optimization of a design.
