Define Protocol
-A convention that controls or enables the connection, communication and data transfer between two computing endpoints. (wikipedia)

The use of differnt Protocols
[IP] - Stands for The Internet Protocol. A data-oriented protocol used for communicating data across a packet-switched internet work.
[TCP] - Stands for The Transmission Control Protocol. One of the core protocols of the Internet protocol suite. TCP is reliable, in-order delivery of a stream of bytes, making it suitable for applications like file transfer and email.
[http] - Stands for Hypertext Transfer Protocol .A communication protocol for the transfer of information on intranets and the world wide web. Its original purpose was to provide a way to publish and retrieve hypertext pages over the internet.
[smtp] - Stands for Simple Mail Transfer Protocol. Standard for email transmissions across the internet.
[FTP] - Stands for File Transfer Protocol. A network protocol used to transfer data from one computer to another through a network, such as over the internet.

What Does GUI stand for?
Graphical User Interface

What was it used for GUI?
It was a blank screen with no graphics that we have now. There were different commands and codes that needed to be remembered in order to get to different things. It was much harder then because if we were to forget a command it wouldn't work. Now its much easier it has tabs and graphics to make it easier to navigate instead of having the type commands.

Difference Between serial and parallel data transmissons:
Serial transmission are bits that are sent over a single wire individually and Parallel transmissions are multiple wires. It can transmit mulitiple bits simultaneously, which allows for higher data transfer rates than can achieved than with serial transmissions.

Define URL:
Stands for uniform resource locator. There are two meanings one is it means web page address the other means it is a compact string of characters for a resource available via the Internet.

Components that that make up the URL
Address bars vary in appearance depending on the web browser displayed in. They ususally have a domain name and an origin (for example .com or .org or .gov)

What is a ' error detection':
Error detection coding is designed to permit the detection of errors. Once detected, the receiver may ask for a re-transmission of the erroneous bits, or it may simply inform the recipient that the transmission was corrupted.

Example of a error detection:
Berger code - can detect all unidirectional errors.
