Q: What is computer software?
A: Computer software refers to programs and instructions that tell a computer what to do. It includes operating systems, application software, and utility programs.
Q: What is an operating system?
A: An operating system is software that manages computer hardware and software resources, provides an interface for users, and enables the execution of programs.
Q: What is application software?
A: Application software is software designed for specific tasks or applications, such as word processors, spreadsheets, and graphic design programs.
Q: What is a computer network?
A: A computer network is a collection of interconnected computers and devices that can communicate and share resources with each other.
Q: What is a Local Area Network (LAN)?
A: A Local Area Network (LAN) is a network that connects computers and devices within a limited geographical area, such as a home, office, or school.
Q: What is a Wide Area Network (WAN)?
A: A Wide Area Network (WAN) is a network that covers a large geographical area and connects multiple LANs or computers over long distances.
Q: What is the Internet?
A: The Internet is a global network of interconnected computers and networks that enables communication and the exchange of information worldwide.
Q: What is the World Wide Web (WWW)?
A: The World Wide Web (WWW) is an information system on the Internet that allows users to access and navigate websites through hyperlinks.
