"A computer network is a set of computers sharing resources located on or provided by network nodes."
The study of communication between computers, including protocols like TCP/IP, routing algorithms, and network security.
Network topology: The physical or logical arrangement of a network and how devices are connected to one another.
Network protocols: The rules and formats used for communication between devices on a network.
Network devices: Equipment used to enable communication between devices on a network, such as routers, switches, and hubs.
The OSI model: The Open Systems Interconnection model, a framework for understanding how data is transmitted across a network.
TCP/IP protocol: The Transmission Control Protocol/Internet Protocol used to enable communication across the internet and local networks.
IP addressing: The methods used to assign numerical addresses to devices on a network.
Subnetting: The process of dividing an IP network into smaller subnetworks.
DNS: The Domain Name System used to map domain names to IP addresses.
VPN: Virtual Private Network, a secure way to connect remote devices to a network.
Wireless networks: Networks that allow devices to connect wirelessly using technologies such as Wi-Fi or Bluetooth.
Network security: Methods used to protect a network from unauthorized access or attacks.
Network management: Tools and techniques used to monitor and manage the performance of a network.
Network troubleshooting: Techniques used to diagnose and resolve issues on a network.
Cloud computing: The use of remote servers to store, manage, and process data rather than locally on a personal computer.
Network architecture: The structure and design of a network, including hardware, software, and communication protocols.
Local Area Network (LAN): A network that connects computers and devices within a limited geographical area, such as a building or campus.
Wide Area Network (WAN): A network that connects computers and devices over a large geographical area, such as a city, state or country.
Metropolitan Area Network (MAN): A network that connects computers and devices within a city or metropolitan area.
Storage Area Network (SAN): A dedicated network used to connect storage devices, such as disks or tapes, to servers.
Wireless Local Area Network (WLAN): A LAN that uses wireless communication technology to connect computers and devices.
Virtual Private Network (VPN): A network that uses a public network, such as the Internet, to create a secure connection between two private networks.
Peer-to-Peer Network (P2P): A network in which each computer can act as both a server and a client, allowing users to share files and resources directly.
Client-server Network: A network in which one or more computers act as servers to provide resources and services to client computers.
Cloud Network: A network that utilizes cloud computing technology to provide access to resources and services over the Internet.
Campus Area Network (CAN): A network that connects multiple LANs within a university or organization.
Intranet: A network that is only accessible to employees within an organization and is used to share internal resources and services.
Extranet: A network that allows controlled access to external users, such as vendors or partners, to access internal resources and services.
Industrial Control System (ICS): A network used to control and monitor industrial processes or systems, such as manufacturing or power plants.
"Computers use common communication protocols over digital interconnections to communicate with each other."
"These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods."
"The nodes of a computer network can include personal computers, servers, networking hardware, or other specialized or general-purpose hosts."
"They are identified by network addresses and may have hostnames."
"Hostnames serve as memorable labels for the nodes and are rarely changed after initial assignment."
"Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol."
"Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications protocols to organize network traffic, the network size, the topology, traffic control mechanisms, and organizational intent."
"Computer networks support many applications and services, such as access to the World Wide Web, digital video and audio, shared use of application and storage servers, printers and fax machines, and use of email and instant messaging applications."
