Transmission Line :
The basic building block of any communications facility is the transmission line.

Networking :
Advances in technology have led to greatly increased capacity and the concept of integration, allowing equipment and networks to work simultaneously.

LANs and WANs :
There are tow board categories of networks: Local Area Network ( LAN ) . Wide Area Network ( WAN ) .

Wide Area Network (WAN):
Span a large geographical area
Require the crossing of public right-of-
ways
Rely in part on common carrier circuits
Typically consist of a number of
interconnected switching nodes
![Page 17: Principles of communication systems](https://reader033.vdocuments.us/reader033/viewer/2022051000/56812d88550346895d929b42/html5/thumbnails/17.jpg)

Wide Area Network (WAN):
Alternative technologies used include: Circuit switching Packet switching Frame relay Asynchronous Transfer Mode (ATM)

Local Area Network (LAN):
Smaller scope, typically a single building .
Usually owned by the same organization
that owns attached devices .
Internal data rates greater than WANs .
Most common configurations are switched
LANs and wireless LANs .

The Internet:
Internet evolved from ARPANET
Developed to solve the dilemma of
communicating across arbitrary,
multiple, packet-switched network
TCP/IP provides the foundation

Metrics Units
The main prefixes we use:
Use powers of 10 for rates, powers of 2 for
storage E.g., 1 Mbps = 1,000,000 bps, 1 KB = 1024 bytes “B” is for bytes, “b” is for bits
