TCP/IP Introduction

Computer Communication Protocol

A computer communication protocol is a description of the rules computers must follow to communicate with each other.

What is TCP/IP?

TCP/IP is the communication protocol for communication between computers on the Internet.
TCP/IP stands for Transmission Control Protocol / Internet Protocol.
TCP/IP defines how electronic devices (like computers) should be connected to the Internet, and how data should be transmitted between them.

Inside TCP/IP

Inside the TCP/IP standard there are several protocols for handling data communication:
  • TCP (Transmission Control Protocol) communication between applications
  • UDP (User Datagram Protocol) simple communication between applications
  • IP (Internet Protocol) communication between computers
  • ICMP (Internet Control Message Protocol) for errors and statistics
  • DHCP (Dynamic Host Configuration Protocol) for dynamic addressing

TCP Uses a Fixed Connection

TCP is for communication between applications.
If one application wants to communicate with another via TCP, it sends a communication request. This request must be sent to an exact address. After a "handshake" between the two applications, TCP will set up a "full-duplex" communication between the two applications.
The "full-duplex" communication will occupy the communication line between the two computers until it is closed by one of the two applications.
UDP is very similar to TCP, but simpler and less reliable.

IP is Connection-Less

IP is for communication between computers.
IP is a "connection-less" communication protocol.
IP does not occupy the communication line between two computers. IP reduces the need for network lines. Each line can be used for communication between many different computers at the same time.
With IP, messages (or other data) are broken up into small independent "packets" and sent between computers via the Internet.
IP is responsible for "routing" each packet to the correct destination.

IP Routers

When an IP packet is sent from a computer, it arrives at an IP router.
The IP router is responsible for "routing" the packet to the correct destination, directly or via another router.
The path the packet will follow might be different from other packets of the same communication. The router is responsible for the right addressing, depending on traffic volume, errors in the network, or other parameters.

Connection-Less Analogy

Communicating via IP is like sending a long letter as a large number of small postcards, each finding its own (often different) way to the receiver.

TCP/IP

TCP/IP is TCP and IP working together.
TCP takes care of the communication between your application software (i.e. your browser) and your network software.
IP takes care of the communication with other computers.
TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive.
IP is responsible for sending the packets to the correct destination.

Conan Edogawa dan Haibara

Conan Edogawa, siapa sih yang tak kenal sosokdetective cilik , lucu, keren, ganteng plus super cerdas ini? Ya, bagaimana mungkin Conan tidak lebih cerdas dari teman-temannya, karena sebenarnya dia adalah Shinichi Kudo yang telah diberi racun berupa obat Apotixin 4869 oleh organisasi hitam yang membuat tubuhnya mengecil. Begitu pula dengan Haibara, yang sebenarnya adalah Shiho Miyano. Shiho Miyano atau Haibara awalnya termasuk anggota dari organisasi hitam, dialah orang yang membuat obat Apotixi 4869 atau APTX 4869. Setelah mengetahui bahwa obat tersebut akan digunakan untuk kejahatan, Shiho berusaha untuk keluar dari organisasi hitam tetapi ia malah di kurung. Satu-satunya jalan keluar adalah meminum obat APTX 4869 buatannya, sehingga ia mengecil, bisa kabur dan menyamar menjadi Haibara. Conan dan Haibara sama-sama mengetahui hal ini. Sementara Conan tinggal bersama dengan Detective Mouri dan kekasihnya selama menjadi Shinichi yaitu Ran putra ...
