DATA COMMUNICATION

It is a type of data transmission where all bits are sent one after another.

Serial

It is a type of data transmission where multiple bits are sent simultaneosly.

Parallel

It is a type of data transmission that cost-effective and reliable but slower and ideal for long distances.

Serial

It is type of data transmission that is faster but costly, limited to short distances.

Parallel

What are the two major disavantages of parallel data transmission?

• Clock Skew

• Crosstalk

It is a type of line configuration that provides a dedicated link between two devices.

Point-to-Point

It is a type of line configuration where more than two devices share a single link.

Multipoint / Multidrop

Explain point-to-point and multipoint comparisons (cost, security, and bandwidth)

Point-to-point

• High (more cables)

• High (private channel)

• Max capacity available

Multipoint

• Low (less cables)

• Low (shared channels)

• Bandwidth is split / shared

It is a network component considered as the source or destination of data.

End Devices / Hosts

It is an end device that access a service made available by a server

Client

It is an end device that provides functions and services for clients

Server

It is a program that runs on computers and servers that allows computers to communicate over a network

Network Operating System (NOS)

This are strict rules that govern how data is packaged, address, and sent.
