Ethernet: A widely used networking technology for local area networks (LANs) that defines wiring and signaling standards.

Wi-Fi (Wireless Fidelity): A wireless networking technology based on the IEEE 802.11 standards, allowing devices to connect to a local area network wirelessly.

Bluetooth: A short-range wireless communication technology used for connecting devices over short distances, commonly found in smartphones, headphones, and IoT devices.

Cellular Networks: Mobile communication networks that provide wireless voice and data services to mobile devices using technologies such as GSM, CDMA, LTE, and 5G.

Fiber Optics: A communication technology that transmits data through optical fibers, offering high bandwidth and long-distance transmission capabilities.

LAN (Local Area Network): A network that connects devices within a limited geographic area, such as a home, office, or campus, allowing them to share resources and communicate with each other.

WAN (Wide Area Network): A network that spans a large geographic area, connecting multiple LANs or other networks together, often using leased lines, satellites, or public infrastructure.

VPN (Virtual Private Network): A network technology that creates a secure, encrypted connection over a public network, allowing users to access private networks remotely.

VoIP (Voice over Internet Protocol): A technology that allows voice communication over the internet, enabling services like internet telephony, video conferencing, and voice messaging.

DSL (Digital Subscriber Line): A technology that provides high-speed internet access over traditional copper telephone lines, offering faster speeds than dial-up connections.

Satellite Communication: Communication technology that uses satellites to transmit data over long distances, often used for remote locations or where terrestrial networks are impractical.

NFC (Near Field Communication): A short-range wireless communication technology that enables devices to establish communication by bringing them close together, commonly used in contactless payments and data transfer.

Packet Switching: A networking technique where data is broken down into packets for transmission over a network, allowing for efficient use of network resources and flexible routing.

Routing and Switching: Networking technologies that involve directing data packets between devices on a network, ensuring they reach their intended destinations efficiently.

Firewalls and Network Security: Technologies designed to protect networks from unauthorized access, malicious attacks, and data breaches, including firewalls, intrusion detection systems, and encryption.

Cable Modems: Networking devices that provide high-speed internet access over cable television infrastructure, commonly used in residential and small business environments.

Ethernet Switches: Networking devices that connect multiple devices within a LAN, allowing them to communicate with each other by forwarding data packets based on MAC addresses.

Wireless Access Points (WAPs): Devices that allow wireless devices to connect to a wired network, providing wireless connectivity within a specific area or building.

Unified Communications: Integration of various communication services, such as voice, video, messaging, and collaboration tools, into a single platform for improved efficiency and productivity.

Network Management and Monitoring: Tools and technologies used to monitor, manage, and troubleshoot computer networks, ensuring optimal performance and reliability.
