7 Layer OSI

OSI is a protocol which is used by international networking standard. This protocol is more reliable than TCP/IP. But if learn the theory it's more complicated. 7 layer OSI could be known as "Please Do Not Throw Sausage Pizza Away" or " All People Seems To Need Data Process". It's easy to remind right? Now, i'll give you some explanation and it's function. Check this!

Layer	Function	Example
Application	as interface application within network functionality and manage how could the application access the network then makes error message	NNTP, SIP, DHCP, FTP, Gopher, HTTP, NFS, SNMP, Telnet, POP3
Presentation	translating, data encryption, and data compress	ASCII, Midi, MPEG
Session	Define how the connection established, running or disconnected	SQL, x-Window, ZIP, NetBIOS, ASP, RPC, NFS
Transport	do arrangement, divided big data into small packet and authorize connection from several network	TCP, SPx, UDP, IPx
Network	route the data from source to destination through transmission exact LAN MAN WAN	IPx, IP, ICMP, ARP, RARP, IGRP,BGP, OSPK
Data Link	the bridge between network media and protocol layer. authorize the last binary data packet which is derived from highest level into a discrite packet before going to physical layer	802.3 [ethernet], 802.11 a/b/g/n, Mac, FDDI, Frame relay, SDLC, PPP, Token ring
Physical	define communication media, voltage, flexible so that it can integrate several different network and physical media	RS 232, 10 Base T, 100 Base Tx, DSL
