Network Management

Networking refers to the practice of connecting computers and other devices together to share resources and communicate with each other. It involves both the physical hardware components and the software protocols and standards that govern communication between devices. Networking enables data transfer, resource sharing, and collaboration among users and devices within a network.

Local Area Network (LAN): A network that covers a small geographic area, typically within a single building or campus. LANs are commonly used in homes, schools, and businesses to connect devices such as computers, printers, and servers

Wide Area Network (WAN): A network that spans a large geographic area, often connecting multiple LANs across different locations.

Network Devices

Router: A networking device that forwards data packets between different networks. Routers operate at the network layer (Layer 3) of the OSI model and use routing tables to determine the best path for forwarding packets.

Switch: A networking device that connects multiple devices within a LAN and forwards data packets based on the MAC addresses of the devices.

Access Point: A device that allows wireless devices to connect to a wired network

Modem: A device that modulates and demodulates digital signals to enable communication over analog transmission lines, such as telephone lines or cable lines.

Network Security

Firewalls: Security devices that monitor and control incoming and outgoing network traffic based on predefined security rules.

VPN (Virtual Private Network): A secure network connection that allows users to access a private network over a public network, such as the internet

Intrusion Detection and Prevention Systems (IDPS): Security systems that monitor network traffic for signs of suspicious activity or known attack patterns. IDPS can detect and respond to security threats in real-time to protect networks and data from unauthorized access or damage.
