Some key Terms- The Internet and Web Design

Define the term Protocol.

Protocol is a set of rules governing the format of messages that are exchanged between computers.

What are the following protocols used for?
TCP/IP- (Transmission Control Protocol/Internet Protocol) Purpose to allow computers to communicate over long distance networks
HTTP- (Hypertext Transfer Protocol) standard mechanism for the exchange of application-level messages between devices on the web.
SMTP- (Simple Mail Transfer Protocol) sending and recieving emails
FTP- (File Transfer Protocol) copy files between their local systems and any other system that their network can reach.


What does GUI stand for? What was used before GUI?

GUI stands for 'Graphical User Interface'. Dos was used before GUI.

There are two methods of data transmission-Series and Parallel. Explain the difference between them.
The two methods of data transmission are Series and Parallel. The difference between the both are that series is much easier, economical and has the most simplest method for transferring digital information. In series, transmission is sent one bit at a time. This is preffered because it is not expensive. It can trabsfer data over long distances.

The Parallel data transmission tranmits all binary data and each part needs it's own path. All bits can be transferred at the same time and it can move a large amount in a period of time. The let down on this is the interconnecting cables between the 2 points.(Cabling=complicated and expensive).

Define the term URL? Explain the components that make up the URL?
URL stands for Uniform Resource Locator. This is the address of a website in the world wide web(the internet).
The components to make up a URL:

• A scheme: This identifies the protocol to access the resource.(it can be HTTP or HTTPS)
• A Host: Identifies host that hosts the resource. Provides service in the name of this. This can be followed by a port number(http://www.example.com/)
• A Path: Identifies source within the host that the web client wants to access(/software/htp/cics/index.html).

Quizelet

Mr. Lennon found a website called "Quizelet", which has many quizzes on different topics. I found that it is interactive at so many levels. Completing quizzes, your test of knowledge, putting an input and respond by giving a result to your knowledge, also it is allowing to be authors on this website as on the Internet.
