Study Notes

Network Fundamentals

A network is a digital telecommunications system enabling nodes to share resources.
A client requests services from a server.
A server provides functions for clients.
A single device can be both a client and a server (e.g., peer-to-peer networks).

Switches

Switches operate at Layer 2 (Data Link Layer) and connect devices within the same local area network (LAN).
They have multiple ports for connecting endpoints.
They do not connect different LANs or networks over the internet.

Routers

Routers operate at Layer 3 (Network Layer).
They connect different LANs.
They facilitate data transmission over the internet.
They have fewer ports than switches.

Firewalls

Firewalls are specialized hardware devices controlling network traffic.
They can be positioned inside or outside a network.
They monitor traffic according to configured rules.
Advanced firewalls with wider filtering are called Next-Generation Firewalls.
Host-based firewalls are software applications filtering traffic on a single computer.
