Types of Networks:

WAN - Country or continent MAN - City or campus LAN - Room or building PAN - Personal

Most Common tech used on LANs are Ethernet and WIFI

Bus Topology-

Pros: Simple, one line Cons: One error causes mass issues

Ring Topology-

Pros: Every system gets a turn, no collisions Cons: Systems are idle, can be inefficient

Mesh Topology-

Pros: High redundancy paths, Fault tolerant Cons: Expensive and complicated

Star Topology-

Pros: Cable break only affects one node, no sharing of cables Cons: Lots of cabling, if central device fails network is down

Star Mesh Hybrid-

Balance of efficiency and redundancy, backbone devices are meshed.

MAC ADDRESS (Media Access Control)-

MAC addresses have has an electronic hardware interface to the LAN called a Network Interface Card (NIC)

12 Hexadecimal Digits

IP addresses include both the Network ID (ZIP code) and Host ID (Street address)

32 bit binary string

Devices use binary logic to communicate on the network
