The document provides an overview of internet connectivity, detailing the necessary hardware, types of connections (wired and wireless), and protocols used for communication. It discusses web browsers, web pages, home pages, domain names, web servers, and IP addresses, highlighting their roles in accessing and sharing information on the internet. Additionally, the document emphasizes the World Wide Web (WWW) as a significant subset of the internet that organizes and links documents globally.
Basics of IT
- 1. Name- Robin Singh Sandhu
- 2. To share information or communicate with others, computers are required to be connected. This interconnection of computers is called a network. An interconnection of networks is called INTERNET. To connect to the internet following hardware are required: Computer Modem
- 3. There are various types of connections provided by different internet service providers. Wired connections Wireless connections
- 4. . In this type of connection, the internet connection is provided through wires.
- 5. A dial up connection allows you to connect to the internet using your telephone line. The advantage of this this type of connection is that it is very economical.
- 6. . This is considered as one of the best type of connection available to home users
- 7. ADSL(Asymmetric digital subscriber line) connections are becoming more & more widely available & can provide an excellent internet connection.
- 8. . Wireless internet access, sometimes refers to as a hotspot, is a LAN(local area network) ran by radio waves rather than wires. You need data card for this connection.
- 10. The Internet is the network of networks. It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the internet. The world wide web or WWW is a way of accessing information over the medium of the medium of internet. The WWW is a part of the internet& is collection of the online documents. WWW uses HTTP(Hyper Text Transfer Protocol) to link documents with each other around the world. These documents can contain pictures, sounds etc.
- 11. So, we can say, if there are many rules on the internet like e-mails, which relies on SMTP(Simple Mail Transfer Protocol), news groups, instant messaging & FTP(File Transfer Protocol), & one such language called as HTML (Hyper Text Mark-up Language) is used by the word wide web.
- 12. Web Browser Web Page Home Page Domain Name Web Server IP Address
- 13. . A web browser is a software application for retrieving, presenting, and traversing information resources on the WWW. A web browser can also be defined as an application software or program designed to enable users to access, retrieve and view documents and other resources on the Internet. Although browsers are primarily intended to use the WWW, they can also be used to access information provided by web servers in private networks or files in file systems. The major web browser is Google chrome.
- 14. . A web page or webpage is a document or information resource that is suitable for the World Wide Web and can be accessed through a web browser and displayed on a monitor or mobile device. Web pages may consist of files of static text and other content stored within the web server's file system (static web pages), or may be constructed by server-side software when they are requested (dynamic web pages). Client-side scripting can make web pages more responsive to user input once on the client browser.
- 15. . This is the starting point or front page of a Web site. This page usually has some sort of table of contents on it and often describes the purpose of the site. For example, http://www.apple.com/index.ht ml is the home page of Apple.com. When you type in a basic URL, such as "http://www.cnet.com," you are typically directed to the home page of the Web site. Many people have a "personal home page," which is another way the term "home page" can be used.
- 16. . This is the name that identifies an Web site. For example, "microsoft.com" is the domain name of Microsoft's Web site. A single Web server can serve Web sites for multiple domain names, but a single domain name can point to only one machine. For example, Apple Computer has Web sites at www.apple.com, www.info.apple.com, and store.apple.com. Each of these sites could be served on different machines.
- 17. . A Web server is a computer system that hosts websites. It runs Web server software, such as Apache or Microsoft IIS, which provides access to hosted webpages over the Internet. Most Web servers are connected to the Internet via a high-speed connection, offering or faster data transmission rates. A fast Internet connection allows Web servers to support multiple connections at one time without slowing down.
- 18. . Also known as an "IP number" or simply an "IP," this is a code made up of numbers separated by three dots that identifies a particular computer on the Internet. Every computer, whether it be a Web server or the computer you're using right now, requires an IP address to connect to the Internet. IP addresses consist of four sets of numbers from 0 to 255, separated by three dots. For example "66.72.98.236" or "216.239.115.148". However, if you connect to the Internet through a network or broadband connection, it is more likely that you have a static IP address.
