Increase of fuel price in Indonesia and model osi

This is a lesson that love, computer networks are sma tertumbuh since I graduated, the academy continue to computers, computer networks led this evening by mr.sumarna as a lecturer, he is quite well and make us understand and grasp the theory that it provides. The theory that he gave was about the "OSI model" on a computer network or "open systems interconnectios"

A little story from me, this is the day that kept me busy, that morning I was asked to join to take my friend to Jakarta with the Jakarta Police to meet with his brother. After returning from there, I was surprised because all along the road near my house has a lot of students in the middle of the street demonstrations to reject the husband of fuel price increases, according to the student with the increase of fuel oil in Indonesia, the government is not concerned with the little people. Therefore they hold demonstarsi from various campuses in central Jakarta, with burning tires, and holding their banners and speeches not only that they were escorted by many police to maintain security at the demonstration site

Anyone who is obliged to pursue the world of computer networks and a must to learn the standard or reference model (OSI) seven-layer model, osi models often used to explain the workings of a computer network logically, the model was introduced in 1984 osi, osi models generally divide various network functions into seven layers, osi model of a reference or a reference for anyone who wants to understand the workings of a computer network j, model osi is not a protocol, protocol is a set of rules used in data communication, eg protocol is TCP / IP, IPX , NetBIOS, PPP and others.

Osi model consists of layers or strata has 7 pieces, namely:
A. Physical
2. Data link
3. Network
4. Transport
5. Session
6. Presentation
7. Application

A. Physical (electrical signals and cabling)
2. Data link (transmirts packets from node to node based on station address)
3. Network (route the data to different LANs and WANs)
4. Transport (ensures delivery of entire file or message)
5. Session (starts, stops the session)
6. Presentation (encryption of data)
7. Application (type of communication: e-mail, ftp, client / server)

A. Media layer> bits> physical> lower layers
2. Media layer> frames> data link> lower layers
3. Media layer> packets> Networks> lower layers
4. Host layer> segments> transport> lower layers
5. Host layer> data> session> upper layer
6. Host layer> data> presentation> upper layer
7. Host layer> data> application> upper layer

On this subject quite a lot of students who pay attention to the explanation of mr.sumarna because our seriousness, we can understand the lessons he gave, at that time we were about to convert binary numbers to decimal and decimal to binary, from so many students are just a few students who can answer it, including me: D

Thus, the upper layers define how the application (on a host) to communicate with each other or a similar application and the user (the host) else. While the lower layers define how data is transported (via the media network) from one host to another host. Hopefully this article useful.

I hope the article Accounting, Administration, Agribusiness, Business, computer, Development, Economy, education, Engineering, Industry, Information, Management, science, Taxation, Technical about Increase of fuel price in Indonesia and model osi this can useful for you
