Kemudian alamat tersebut akan dilewatkan oleh suatu protocol HTTP melewati port 80 atau 443 pada server. Web browser akan mengirimkan suatu aturan yang biasa disebut protocol, protocol yang biasa digunakan adalah TCP/IP. Setelah dikirimkan ke web server, maka web server akan merespon request dari web browser tersebut. Web server akan memeriksa web file, apakah ada atau tidak alamat yang di request oleh browser tadi dan mengirimkan kembali, lalu browser akan menerjemahkan coding HTML yang dikirimkan oleh server menjadi suatu halaman web.

Internet Safety

The Internet can be a wonderful resource for kids. They can use it to research school reports, communicate with teachers and other kids, and play interactive games. Kids who are old enough to punch in a few letters on the keyboard can literally access the world.

But that access can also pose hazards. For example, an 8-year-old might do an online search for "Lego." But with just one missed keystroke, the word "Legs" is entered instead, and the child may be directed to a slew of websites with a focus on legs — some of which may contain pornographic material.

That's why it's important to be aware of what your kids see and hear on the Internet, who they meet, and what they share about themselves online.

Just like any safety issue, it's wise to talk with your kids about your concerns, take advantage of resources to protect them, and keep a close eye on their activities.
Internet Safety Laws

A federal law, the Children's Online Privacy Protection Act (COPPA), was created to help protect kids online. It's designed to keep anyone from obtaining a child's personal information without a parent knowing about it and agreeing to it first.

COPPA requires websites to explain their privacy policies on the site and get parental consent before collecting or using a child's personal information, such as a name, address, phone number, or Social Security number. The law also prohibits a site from requiring a child to provide more personal information than necessary to play a game or participate in a contest.

But even with this law, your kids' best online protection is you. By talking to them about potential online dangers and monitoring their computer use, you'll help them surf the Internet safely.

Uses of Internet

The internet is computer based global information system. It is composed of many interconnected computer networks. Each network may link thousands of computers
enabling them to share information. The internet has brought a transformation in many aspects of life. It is one of the biggest contributors in making the world into a global village. Use of internet has grown tremendously since it was introduced. It is mostly because of its flexibility. Nowadays one can access the internet easily. Most people have computers in their homes but even the ones who don?t they can always go to cyber cafes where this service is provided.
The internet developed from software called the ARPANET which the U.S military had developed. It was only restrict to military personnel and the people who developed it. Only after it was privatized was it allowed to be used commercially.
The internet has developed to give many benefits to mankind. The access to information being one of the most important. Student can now have access to libraries around the world. Some charge a fee but most provide free services. Before students had to spend hours and hours in the libraries but now at the touch of a button students have a huge database in front of them. The Online chatting also has its own hazards. When one is talking to strangers one does not really know who they are. They can be just anybody pretending to be someone else. Many cases have been reported of child abuse happening this way. There is no way of verifying who the other really is. Many industries have also suffered a loss, especially the music and movie industry. Movies and songs are available for free on the internet which has affected the sale levels of artists. People make their own cds and sell them. The phone industry has also suffered because more people are making calls through the internet.

There is also a certain loss of privacy because now most people store all their information on the computer and when you connect online, anybody can hack ones computer and get into it. This had already been done with many e-mail inboxes. Sites also have been hacked leading to major mishaps. Sending a virus on the Web has also been another way that people?s computers have been infected.

The internet has brought new opportunities to government, business and education. Governments use it for various processes such as distribution of information and internal communication. Businesses use it to sell and buy products online and also to interact with other businesses. New business opportunities have sprouted because of the internet. Auctions take place and sites like ?e-bay? provide the opportunity for everyone to put their things on auction. Companies use it

Why Internet Marketing Is Important

There's no more stopping the Internet. You can't deny that it has become a part of many people's lives and many are foregoing other traditional media for the internet. More and more people getting their information and other requirements online so it only makes sense for businesses to use the internet as a marketing tool. The internet can be one of the most efficient and cheapest ways to promote your company and products.

Print advertising is one of the most expensive advertising media available to businesses. Print media includes newspapers, magazines, phone books and journals. Because of the increasing costs of print media production, print advertising fees can be exorbitant. TV and radio advertising can reach a wider audience but just like print advertising broadcast media advertising fees are expensive.

With the Internet, promoting a business can be done for a shoe-string budget. Aside from cost-efficiency, one advantage of online advertising is that there many creative and efficient ways to advertise online. The Internet is much more flexible tool than print or even broadcast media. Aside from static ads, you can create active ads with sounds, motions, etc. You can also have links and create interactive advertising features. There are many creative ways to highlight your products online and they are often much more affordable than creating advertising for TV.

There are also a number of cost-efficient ways to advertise online. One method is to sign up for a cost-per-click scheme which means you only pay for every valid click to your ad or your link. With this scheme, you don't have to pay for the ad placement unless someone actually finds an interest on your ad and clicks on it.

The most important reason why businesses should consider using the internet as a marketing tool is because it is here to stay. In the next few years, millions more will get connected to the internet, it will become an even bigger force and many more people will look and find what they need online. The internet has allowed people to communicate instantaneously to anybody around the world and it has changed the way people got their information. It has even changed the way people shopped. It will continually change the way people lead their lives in the coming years. The internet is continually breaking barriers everyday. In the future, it will become an even more essential part of people's lives so it's only sensible for companies to utilize this modern communication tool to their advantage. With the internet anyone can reach anybody from anywhere practically for free. A small home-based company can reach a potential business partner, a client, a supplier who lives half-way around the world. There are no technologies available yet that has the same reach as the internet. Whereas before it would cost an arm and a leg to communicate with someone from another continent, now it is has become affordable. Aside from the distance, the internet also allows entrepreneurs to reach more people for less money.

What Is Internet

The internet in simple terms is a network of the interlinked computer networking worldwide, which is accessible to the general public. These interconnected computers work by transmitting data through a special type of packet switching which is known as the IP or the internet protocol.

Internet is such a huge network of several different interlinked networks relating to the business, government, academic, and even smaller domestic networks, therefore internet is known as the network of all the other networks. These networks enable the internet to be used for various important functions which include the several means of communications like the file transfer, the online chat and even the sharing of the documents and web sites on the WWW, or the World Wide Web.

It is always mistaken said that the internet and the World Wide Web are both the same terms, or are synonymous. Actually there is a very significant difference between the two which has to be clear to understand both the terms. The internet and World Wide Web are both the networks yet; the internet is the network of the several different computers which are connected through the linkage of the accessories like the copper wires, the fiber optics and even the latest wireless connections. However, the World Wide Web consists of the interlinked collection of the information and documents which are taken as the resource by the general public. These are then linked by the website URLs and the hyperlinks. Therefore World Wide Web is one of the services offered by the whole complicated and huge network of the internet.

The use of IP in the Internet is the integral part of the network, as they provide the services of the internet, through different layers organization through the IP data packets. There are other protocols that are the sub-classes of the IP itself, like the TCP, and the HTTP.
