Transmission Line :

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

13

Transmission Mediums :

Two mediums currently driving the evolution of data communications transmission are:

Networking :

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

15

LANs and WANs :

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

19 Apr 2023 Networks and Communication Department

16

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

19 Apr 2023 Networks and Communication Department

17

Wide Area Network (WAN):

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

19 Apr 2023 Networks and Communication Department

18

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
