"A computer network is a set of computers sharing resources located on or provided by network nodes."
Network Basics refers to a foundational understanding of how computer networks function and operate.
Network Topologies: Different ways in which devices on a network can be arranged and connected.
Network Protocols: Rules and standards which computers and devices use to communicate with each other over a network.
IP Addressing: Assigning unique numerical identifiers to devices on a network.
Subnetting: Dividing larger networks into smaller ones to increase efficiency and security.
DNS (Domain Name System): Translating domain names into IP addresses to facilitate communication between devices on a network.
DHCP (Dynamic Host Configuration Protocol): Automatically assigning IP addresses to devices on a network.
NAT (Network Address Translation): Mapping multiple private IP addresses to one public IP address to allow devices on a private network to access the internet.
OSI (Open Systems Interconnection) Model: A conceptual framework for describing how networks work.
Wireless Networking: Connecting devices to a network without cables through the use of wireless signals.
Network Security: Protecting a network from unauthorized access or attacks by hackers or malware.
Network Topology: The layout and structure of a network, including how devices and nodes are connected and what paths data takes through the system.
Network Protocols: The set of rules and standards for communicating between devices on a network, including TCP/IP, HTTP, and DNS.
Network Architecture: The overall design and implementation of a network, including the physical and logical components and connections between them.
Network Security: Techniques and technologies used to protect a network and its data from unauthorized access, viruses and malware, and other threats.
Network Management: The process of monitoring, maintaining, and optimizing a network to ensure it operates efficiently and effectively.
Network Performance: The speed, reliability, and bandwidth that a network provides, including factors like latency, jitter, and throughput.
Networking Devices: The hardware and software components used to build a network, including routers, switches, hubs, servers, and storage systems.
Standards and Regulations: Legal and industry standards that govern networking practices, including data protection and privacy, wireless spectrum allocation, and network security.
"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."
