"A computer network is a set of computers sharing resources located on or provided by network nodes."
Refers to the interconnection of computer systems to enable communication and sharing of resources like data, software and hardware among others.
Network protocols: The rules and procedures for communication between devices on a network.
Network architecture: The arrangement of components and resources that make up a network, including hardware and software.
Network topology: The physical or logical layout of a network, including how devices are connected and communicate with each other.
Network models: Conceptual frameworks that describe the layers and functions of a network, such as the OSI model and TCP/IP model.
Network security: The protection of a network and its data from unauthorized access, attacks, and other threats.
Network administration: The management and maintenance of a network, including tasks such as monitoring, troubleshooting, and configuration.
Network performance tuning: Optimizing the performance of a network, including improving speed and minimizing latency.
Network modeling and simulation: Creating models and simulations of networks to test and optimize their performance.
Network traffic analysis: Monitoring and analyzing traffic on a network, including identifying bottlenecks and identifying potential security threats.
Network testing and verification: Testing and verifying the functionality and performance of a network, including through automated testing and tools such as packet analyzers.
Wireless networking: Networking technologies that allow devices to communicate over wireless connections, such as Wi-Fi and Bluetooth.
Internet connectivity: The technologies and protocols that enable devices to connect to and communicate over the internet, including DNS, HTTP, and TCP/IP.
Cloud computing: The use of remote servers and resources to store and process data, typically accessed over the internet.
Network virtualization: The creation of virtual versions of networks, devices, and resources, using software and other virtualization technologies.
Network design and implementation: The planning, design, and implementation of networks, including choosing hardware and software, configuring and connecting devices, and ensuring proper operation.
Local Area Network (LAN): A computer network that covers a small geographical area, typically within a single building or campus.
Wide Area Network (WAN): A computer network that covers a large geographical area, typically spanning multiple cities or countries.
Metropolitan Area Network (MAN): A computer network that covers a larger geographical area than a LAN but smaller than a WAN, typically within a single city or metropolitan area.
Wireless Local Area Network (WLAN): A wireless version of a LAN that uses radio waves to transmit data between devices.
Personal Area Network (PAN): A computer network used for communication between devices over a short distance, typically within a person's workspace.
Storage Area Network (SAN): A computer network designed for high-speed transfer of data between storage devices and servers.
Virtual Private Network (VPN): A network that provides a secure connection over a public network, such as the internet, between remote users and a company's private network.
Campus Area Network (CAN): A computer network that covers multiple buildings or areas within a university campus or corporate campus.
Intranet: A private network that is only accessible to an organization's employees and allows for collaboration and communication between them.
Extranet: A private network that allows for communication between an organization and its external partners, such as suppliers or customers.
Home Area Network (HAN): A computer network that connects devices within a person's home, typically used for internet access and media streaming.
Global Area Network (GAN): A computer network that covers a large geographical area, crossing national boundaries and connecting users around the world.
"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."
