1. Jelaskan bagaimana cara kerja internet ketika kita mengakses sebuah halaman web sampai ditampilkan ke browser?

Misalkan seorang yang bernama A ingin membuka sebuah blog, kemudian dia akan mengetikkan alamat url dari blog yang dituju pada browser. 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. Namun jika halaman tersebut tidak ada di dalam web server maka respon yang dikirimkan berupa pesan dengan kode 404 yang berarti tidak ditemukan.

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.

Whereas before it would cost an arm and a leg to communicate with someone from another continent, now it is has become affordable.

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.
