Answer 1

Common uses

E-mail

For more details on this topic, see E-mail.

The concept of sending electronic text messages between parties in a way analogous to mailing letters or memos predates the creation of the Internet. Even today it can be important to distinguish between Internet and internal e-mail systems. Internet e-mail may travel and be stored unencrypted on many other networks and machines out of both the sender's and the recipient's control. During this time it is quite possible for the content to be read and even tampered with by third parties, if anyone considers it important enough. Purely internal or intranet mail systems, where the information never leaves the corporate or organization's network, are much more secure, although in any organization there will be IT and other personnel whose job may involve monitoring, and occasionally accessing, the e-mail of other employees not addressed to them.

The World Wide Web

For more details on this topic, see World Wide Web.



Graphic representation of a minute fraction of the WWW, demonstrating hyperlinksMany people use the terms Internet and World Wide Web (or just the Web) interchangeably, but, as discussed above, the two terms are not synonymous.

The World Wide Web is a huge set of interlinked documents, images and other resources, linked by hyperlinks and URLs. These hyperlinks and URLs allow the web servers and other machines that store originals, and cached copies, of these resources to deliver them as required using HTTP (Hypertext Transfer Protocol). HTTP is only one of the communication protocols used on the Internet.

Web services also use HTTP to allow software systems to communicate in order to share and exchange business logic and data.

Software products that can access the resources of the Web are correctly termed user agents. In normal use, web browsers, such as Internet Explorer and Firefox, access web pages and allow users to navigate from one to another via hyperlinks. Web documents may contain almost any combination of computer data including graphics, sounds, text, video, multimedia and interactive content including games, office applications and scientific demonstrations.

Through keyword-driven Internet research using search engines like Yahoo! and Google, millions of people worldwide have easy, instant access to a vast and diverse amount of online information. Compared to encyclopedias and traditional libraries, the World Wide Web has enabled a sudden and extreme decentralization of information and data.

Using the Web, it is also easier than ever before for individuals and organisations to publish ideas and information to an extremely large audience. Anyone can find ways to publish a web page, a blog or build a website for very little initial cost. Publishing and maintaining large, professional websites full of attractive, diverse and up-to-date information is still a difficult and expensive proposition, however.

Many individuals and some companies and groups use "web logs" or blogs, which are largely used as easily updatable online diaries. Some commercial organisations encourage staff to fill them with advice on their areas of specialization in the hope that visitors will be impressed by the expert knowledge and free information, and be attracted to the corporation as a result. One example of this practice is Microsoft, whose product developers publish their personal blogs in order to pique the public's interest in their work.

Collections of personal web pages published by large service providers remain popular, and have become increasingly sophisticated. Whereas operations such as Angelfire and GeoCities have existed since the early days of the Web, newer offerings from, for example, Facebook and MySpace currently have large followings. These operations often brand themselves as social network services rather than simply as web page hosts.

Advertising on popular web pages can be lucrative, and e-commerce or the sale of products and services directly via the Web continues to grow.

In the early days, web pages were usually created as sets of complete and isolated HTML text files stored on a web server. More recently, websites are more often created using content management system (CMS) or wiki software with, initially, very little content. Contributors to these systems, who may be paid staff, members of a club or other organisation or members of the public, fill underlying databases with content using editing pages designed for that purpose, while casual visitors view and read this content in its final HTML form. There may or may not be editorial, approval and security systems built into the process of taking newly entered content and making it available to the target visitors.

Remote access

Further information: Remote access

The Internet allows computer users to connect to other computers and information stores easily, wherever they may be across the world. They may do this with or without the use of security, authentication and encryption technologies, depending on the requirements.

This is encouraging new ways of working from home, collaboration and information sharing in many industries. An accountant sitting at home can audit the books of a company based in another country, on a server situated in a third country that is remotely maintained by IT specialists in a fourth. These accounts could have been created by home-working bookkeepers, in other remote locations, based on information e-mailed to them from offices all over the world. Some of these things were possible before the widespread use of the Internet, but the cost of private leased lines would have made many of them infeasible in practice.

An office worker away from his desk, perhaps on the other side of the world on a business trip or a holiday, can open a remote desktop session into his normal office PC using a secure Virtual Private Network (VPN) connection via the Internet. This gives the worker complete access to all of his or her normal files and data, including e-mail and other applications, while away from the office.

This concept is also referred to by some network security people as the Virtual Private Nightmare, because it extends the secure perimeter of a corporate network into its employees' homes; this has been the source of some notable security breaches, but also provides security for the workers.

Collaboration

See also: Collaborative software

The low cost and nearly instantaneous sharing of ideas, knowledge, and skills has made collaborative work dramatically easier. Not only can a group cheaply communicate and test, but the wide reach of the Internet allows such groups to easily form in the first place, even among niche interests. An example of this is the free software movement in software development, which produced GNU and Linux from scratch and has taken over development of Mozilla and OpenOffice.org (formerly known as Netscape Communicator and StarOffice).

Internet "chat", whether in the form of IRC "chat rooms" or channels, or via instant messaging systems, allow colleagues to stay in touch in a very convenient way when working at their computers during the day. Messages can be sent and viewed even more quickly and conveniently than via e-mail. Extension to these systems may allow files to be exchanged, "whiteboard" drawings to be shared as well as voice and video contact between team members.

Version control systems allow collaborating teams to work on shared sets of documents without either accidentally overwriting each other's work or having members wait until they get "sent" documents to be able to add their thoughts and changes.

File sharing

For more details on this topic, see File sharing.

A computer file can be e-mailed to customers, colleagues and friends as an attachment. It can be uploaded to a website or FTP server for easy download by others. It can be put into a "shared location" or onto a file server for instant use by colleagues. The load of bulk downloads to many users can be eased by the use of "mirror" servers or peer-to-peer networks.

In any of these cases, access to the file may be controlled by user authentication; the transit of the file over the Internet may be obscured by encryption, and money may change hands before or after access to the file is given. The price can be paid by the remote charging of funds from, for example, a credit card whose details are also passed—hopefully fully encrypted—across the Internet. The origin and authenticity of the file received may be checked by digital signatures or by MD5 or other message digests.

These simple features of the Internet, over a worldwide basis, are changing the basis for the production, sale, and distribution of anything that can be reduced to a computer file for transmission. This includes all manner of print publications, software products, news, music, film, video, photography, graphics and the other arts. This in turn has caused seismic shifts in each of the existing industries that previously controlled the production and distribution of these products.

Internet collaboration technology enables business and project teams to share documents, calendars and other information. Such collaboration occurs in a wide variety of areas including scientific research, software development, conference planning, political activism and creative writing.

Streaming media

Many existing radio and television broadcasters provide Internet "feeds" of their live audio and video streams (for example, the BBC). They may also allow time-shift viewing or listening such as Preview, Classic Clips and Listen Again features. These providers have been joined by a range of pure Internet "broadcasters" who never had on-air licenses. This means that an Internet-connected device, such as a computer or something more specific, can be used to access on-line media in much the same way as was previously possible only with a television or radio receiver. The range of material is much wider, from pornography to highly specialized, technical webcasts. Podcasting is a variation on this theme, where—usually audio—material is first downloaded in full and then may be played back on a computer or shifted to a digital audio player to be listened to on the move. These techniques using simple equipment allow anybody, with little censorship or licensing control, to broadcast audio-visual material on a worldwide basis.

Webcams can be seen as an even lower-budget extension of this phenomenon. While some webcams can give full-frame-rate video, the picture is usually either small or updates slowly. Internet users can watch animals around an African waterhole, ships in the Panama Canal, the traffic at a local roundabout or their own premises, live and in real time. Video chat rooms, video conferencing, and remote controllable webcams are also popular. Many uses can be found for personal webcams in and around the home, with and without two-way sound.

YouTube, sometimes described as an Internet phenomenon because of the vast amount of users and how rapidly the site's popularity has grown, was founded on February 15, 2005. It is now the leading website for free streaming video. It uses a flash-based web player which streams video files in the format FLV. Users are able to watch videos without signing up; however, if users do sign up they are able to upload an unlimited amount of videos and they are given their own personal profile. It is currently estimated that there are 64,000,000 videos on YouTube, and it is also currently estimated that 825,000 new videos are uploaded every day.

Answer 3

The internet is only a tool. Like any tool, it can be used for bad as well as good. It just speeds the process of spreading information or misinformation. You could say the same thing about the telephone or the ball-point pen.

Answer 4

Other than the legal issues, I think you should remember the dependence on technology. I mean, I'm going to be the first person to admit that I'm tech-dependent. I lost my internet for two days, and I found myself hitting alt space and entering an address only to find a Cannot find server page at least ten times a day. Not to mention, I honestly don't even know how to mail a snail mail letter. (I'm 18 and I have never done it.)

Answer 5

Hi..no doubt its the most powerful tool. Besides all the valuable benefits we r gettin out of it ther r numerous adverse effect which comes along with it as the rest have mentioned here. Everything s got its pros and cons depends on wht we r seeking.

Some use it for work purpose and others for entertainment. Even in the entertainment ther r gud and bad ones. Everything is jus one click away. So i feel it really depend on us wht we want and use it for. Some abuse the wonderful technology by hacking, virus etc.It creates so much of prob for other users.

Young users r so exposed to unwanted infos which i feel cud reduce the quality of future generation. Im worried about tht. We dont want kids to grow up with corrupted mind and become unproductive bunch of ppl.Parents shud monitor of course but its not possible all the time since access to net is almost as easy as getting ice cream these days. If parents prohibit they ll go somewher else to access it.

Overall internet can be beneficial as well as harmful..So we shud use it wisely and get the most out of it.

Answer 6

Yes, the internet is a great tool. We wouldn't be reading this if it wasn't for the internet. It has revolutionized the entire world and has thrusted us into the age of technology. Although it can be used for good, it can also be used for some very bad causes, making it an misinformative, and a potentially dangerous place.

Lets start with the missinformitive part. Missinformation is HUGE problem on the web. I see people all the time using YouTube videos as a source for their arguments. YouTube and wikipedia are not acceptable sources for information. Although wikipedia is started to be cleaned up, anyone, anywhere can alter the information making it untrustworthy. But reecent efforts by the admins of wikipedia is making sources become a key part of every page on wikipedia making the situation a lot better. YouTube however is a terrible source. People can post whatever they want... which is a good thing, but also a bad thing. I've seen many people use YouTube in the astronomy and space forum, and they give links to videos with some very inaccurate information. YouTube has a lot of bull saying the moon landing was faked and people actually believe this stuff when it is nothing more than a twisted web of flawed logic. I've even seen some videos that say the sun is a planet! YouTube is an awful source of information, and it is full of videos with potentially dangerous and disturbing content for children making it a potentially harmful environment.

Although chat rooms can be a fun way to connect with people, many preditors rome these places. With old technology the only way to get an address from some one over the internet was to get the information from the person, and often these people will learn to trust potential predetors, and give out information about their location such  as zip codes, phone numbers (which can be used to obtain an address.) and even the exact address of a person. Chat rooms are not safe for the young irresponsible person. New-age chatrooms have made it impossible to give out addresses and phone numbers by blocking out numbers and spelling of numbers in certain patterns that give clues to a person's whereabouts. They also block out profanity and the chat-logs are monitored by moderators to catch potential preditors. A good example of this would be on the online-games such as Roblox and Club Penguin. These websites make it next to impossibe for a person to give out information about their whereabouts. But there are still problems. A hacker can hack into any system and obtain the I.P address of a user. An I.P. address can be used to track a person's whereabouts even down to the exact address. So it isn't a safe world out there. Fortunately it is very rare that a hacker will go this far to obtain an IP address.

Myspace can be a great way to connect with friends, family, and even buisness ascosiates. But recent findings have urged myspace to crack down on some illegal programs going on over myspace. Gangs often use myspace to keep in touch will members over long distances. Myspace is currently shutting down these pages in an attempt to make it a safer environment.

The internet is used for many bad-causes. If one Googles "KKK" results show websites endorsing white supremency.... even trying to recruit people. Although I would love to report these websites and get them thrown in jail, it is unconsitutional for them to do so. They have the freedom of speech as long as they don't do some of the things they are talking about... even though they are. You can't throw a person in jail for being racist but you can if they attack someone. The internet can't shut these sites down, but some hosting services retain the right to shut down any website they want to, but most hosting services don't retain this right. And children will go along with anything they see on the internet which is giving them bad influneces.

The internet is a great place, but also a dangerous place.
