Networks, Types, and Topologies:
A network is a collection of interconnected devices (computers, servers, printers, etc.) that can communicate and share resources with each other. Networks can be classified based on their geographical scope, functionality, and connectivity. Here are some common types of networks:
- LAN (Local Area Network): A LAN is a network that spans a small geographical area, such as a home, office, or building. It allows devices within the network to share resources and communicate directly.
- WAN (Wide Area Network): A WAN covers a larger geographical area, often connecting multiple LANs. It utilizes telecommunication links to establish connectivity over long distances.
- WLAN (Wireless Local Area Network): A WLAN is a LAN that uses wireless technology, such as Wi-Fi, to connect devices without the need for physical cables.
Network topologies refer to the way devices are connected in a network. Some common topologies include:
- Bus Topology: Devices are connected to a central bus or backbone. Data is transmitted to all devices on the network.
- Star Topology: Devices are connected to a central hub or switch. All communication is routed through the hub.
- Ring Topology: Devices are connected in a circular ring, and data flows in one direction around the ring.
- Mesh Topology: Devices are connected to each other in a decentralized manner, providing multiple paths for data transmission.

System Software:
System software refers to the collection of programs and utilities that manage and control the operations of a computer system. Types include operating systems, device drivers, and utility programs.
Application Software:
Application software refers to programs designed to perform specific tasks or provide functionality for end-users. Types include word processors, spreadsheets, web browsers, and multimedia players.
