Hello dear honorable TurkHackTeam followers,
Today i am talked about what is; meaning of OSI , layers and functions to you.
What Is The OSI MODEL?
The OSI Model is network communication standarts which developed by International Organization Standarts. It's formed to Seven Layers.
What Is The Protocol?
Stacks of rules that provides the communicating between of the inter-systems which on the same network
OSI Layers And It's Functions
Physical Layer
Physical layers are transmitting formed datas via various cables like the roads of fibers
These Protocols Which In This Layer
EIA/TIA-232
It connects to two computers to formatted as double to the two computers as display. The voltage regulator and voltaj cutter included itself
EIA/TIA-449
It also known as RS-449. It defines the between of tip points of data devices, interactive communicating devices and the interactive user interface of mechanically side.
RJ45
İt has the 8 pieces of connection ports on it. It assists the device to connecting to local network device
FDDI
It's a speedy computer network. Fiberoptic cables are especially using by which is top speedy computer
V.35
It's a supporter which provides to as 1200 meters upon the packages of 1500 mbps
Ethernet
Processing to the received datas from RJ45
B8ZS
It's a using technique for guarding the connection status.
GBIC/SFP
It's also known as Gigabyte interface converter. It usually using from fiber optic environment
Data Link Layer
Data Link Layer is provides the connection and communication among of physical layer and network layer. In this layer, checking for transmitting of appropriate protocols to the received data layers
These Protocols Which In This Layer
MAC
It also known as Media Access Control. It provides for checking the transmitted datas processing.
802.2
It developed by Electric and Electronic Engineers Institute. It's using for connection detections
Network Layer
This layer is checking the transmitting controls like simplest. This layer also known as datas control center. Processing to on the network layers (router) with network traffic and management works; also IP protocols are working on here.
These Protocols Which In This Layer
IPv4
Could be define as Internet Protocol Of Version 4. It provide the made of internet protocol and IPv6. It's using for 32 bytes adressing
IPv6
Made for better adressing method by thought results of on the IPv4 32 bytes addressing isn't enough.
Transport Layer
Transport layer is attendent by transporting which formed data on the network layer to the upon layers. The service quality of network shown to increasing. The received datas transports with from end to end formatted to upon layers because of that layer is transport layer. The faults of any datas analyzing by this layer.
These Protocols Which In This Layer
TCP
It's provides the data travel from one point to other point.
UDP
It's the sub protocol of the TCP. The data transfers without establishing connection in this protocol.
Session Layer
Could be calling as connection layer; because that layer's mission taking a connection to between of two hosts. If there are more hosts than one; it provides the connection with the correct host.
These Protocols Which In This Layer
NetBIOS
Also known as Network Basic Input/Output System. That protocol which provides to communicating themselves between of the same network connected devices.
RPC
It's remote protocol connection that gain access to connection programs which is without neccesary to any coding.
Named Pipes
It's protocol that provides communicating to between of the UNIX or like that system platforms.
Sockets
It's last data trading to between of the system. It's generally refers to network node.
HTTP & HTTPS
It's protocol that using for communicating; HTTPS is HTTP's sub-protocol which provides secury commmunicating.
TLS
It's protocol of the inter-systems which provides communicating to send with crypto-formatted.
FTP
It's file transfer protocol.
SMTP
It's communicating protocol for sending electronic mails. That provides the connection to between of the host and email sender.
SSH
It's network protocol on non-secured network which provides a secured network service.
PAP
It does PAP identify correcting protocol works of which is known as password correcting protocol. It does identify correction before without access directly to host.
SOCKS
It's network protocol that which provides the changing on another host (proxy host) of network packages in the between of the client and host
Presentation Layer
It's layer that resolving datas of the receiving from remote host. Encrypting, resolving or compressing of the received datas are completing from this layer.
These Protocols Which Here
CSS
Using for helping to HTML. It's pointer language which could formatting
XML
It's pointer language which could be easily reading and writing. It's using for data storing/hiding or its trading.
HTML
It's built from the 1993. It's latestly using the HTML5 version which built from 2014.
It's pointer language which providing to building of the web pages.
Application Layer
It's layer to forming tools which providing be able to network usage of the programs. Could be explain like that:
Network Protocols > Application Layer > Programs
These Protocols Which Here
FTP
It's file transfer protocol.
TFTP
It's simple file transfer protocol although un-upgraded like FTP.
POP3
It's E-Mail transfering protocol.
What's The Differences From IMAP?
IMAP only tracks the headers from received E-Mails; but POP3 tracks the all of the contents of the E-Mails.
SMTP
It's communicating protocol for used to sending E-Mails. It provides the connection between of the host and sender.
IMAP4
It's an E-Mail access protocol. This protocol checking to E-Mails by providing the remote connection to host.
DHCP
DHCP is network protocol that used to for IP adress appointing.
Note:You have seen the same protocols in the some layers; because of that protocols are working in many layers.
