Study Notes

Web Browsing

The Internet was originally created to allow data transfer and communications in case of a nuclear attack or disaster, but it has evolved over the years to become a platform for communication, entertainment, shopping, and more.
The Internet is a huge network of computers connected to local networks, regional networks, and a central structure called the backbone.
People connect to the Internet using a unique address called an Internet Protocol (IP) address, which is a four-part numeric address.

TCP/IP

TCP/IP (Transmission Control Protocol/Internet Protocol) is the common language or protocol used by computers to communicate with each other on the Internet.
Every computer on the Internet has a unique IP address, which is used to identify its location.

DNS

DNS (Domain Name System) is a system used to address computers on the Internet.
A DNS address has two parts: a host name and a domain name.
Common domain names include .com, .edu, .net, .org, and .gov.

World Wide Web

The World Wide Web (WWW) is a method of incorporating footnotes, figures, and cross-references into online hypertext documents, also called web pages.
Web pages are files encoded using HyperText Markup Language (HTML) and are linked together using hypertext links.
A collection of related web pages is called a website, and the first page is called the home page.

Web Browsers

A web browser is a software application used to access and view web pages on the Internet.
Popular web browsers include Microsoft Internet Explorer and Netscape Navigator.

URL

A URL (Uniform Resource Locator) is a unique address used to locate a web page on the Internet.
A URL consists of several parts: http://, www, domain name, folder, and file name.
Each web page has a unique URL, and it is used to access the web page.

Emails

Emails are used to send and receive messages electronically over the Internet.
An email account and an Internet connection are required to send and receive emails.
Email programs, such as Microsoft Outlook Express and Netscape Messenger, are used to manage emails.
Free email service providers, such as Hotmail, Yahoo!, and Rediffmail, offer email accounts.

Email Address

An email address is a unique address used to send and receive emails.
An email address consists of three parts: username, domain name, and top-level domain.
The username refers to the mailbox of the recipient, the domain name refers to the mail server, and the top-level domain refers to the country or type of organization.

Internet Connection

An Internet connection is required to access the Internet and email.
Internet connections can be set up through an Internet Service Provider (ISP) using a dial-up modem, DSL, or cable.
Cybercafes also offer Internet access on an hourly rental basis.

Starting Microsoft Internet Explorer

Microsoft Internet Explorer is a web browser used to access websites on the Internet.
To launch Internet Explorer, go to the Start menu, select Programs, and then Internet Explorer.
The components of Microsoft Internet Explorer include the title bar, menu bar, standard toolbar, shortcut links bar, address bar, contents pane, and status bar.

Accessing Websites

To access a website, enter the URL of the website in the address bar of the Internet Explorer and press Enter.
The browser will then look for the website on the web, and the status bar will display the status of the download.

Using Search Engines

Search engines, such as Google, Altavista, and Hotbot, are used to find information quickly on the Internet.
A search engine has a text box where the user can enter the information they want to search for.
The search engine looks for a match to the words entered and displays a list of search results, which are arranged according to their accuracy.
The user can then browse through the list to find relevant results and open the links by pressing Enter.
