The OSI 7 layer model descibes the theoretical levels of networking on a computer Layer 1 Physical Layer - actual network cable and connectors
Layer 2 Data Link Layer - network address (MAC) and packet switching
Layer 3 Network Layer - internet Protocol (IP) - addressing and packet routing
Layer 4 Transport Layer - Transmission Control Protocol (TCP) - packet sequencing & error correction
Layer 5 Session Layer - Connection control for repeated send/receive (a session)
Layer 6 Presentation Layer - presenting information to application in correct format
LAyer 7 Application Layer - actual display/control of information, layout etc. for two computers to communicate -example chat program the following would occur user types into a chat program on computer A (7)
application accepts input and decides what to do with it (6)
a connection is requested to send to computer B (5)
the message is broken into pieces and encpsulated within a packet (which includes the address to send to and the address from which it came) Packets are given a sequence number(4)(3)
Packet sent across the network using the addressing information to determine where to go to(3)(2)(1) on Computer B the revers happens - packet is put back together - addressing information is removed and eventually displayed on the screen.

∙ 14y agoOSI stands for Open Systems Interconnection and was created by ISO, the International Standards Organization.
The OSI "reference model" divides particular networked processes into seven different layers:
Application (Layer 7)
Presentation (Layer 6)
Session (Layer 5)
Transport (Layer 4)
Network (Layer 3)
Data-Link (Layer 2) and
Physical (Layer 1)
There are at least 2 ways (mnemonics) to help you remember the layers:
1. Please Do Not Throw Sausage Pizza Away.
2. All People Seem To Need Data Processing.

∙ 14y agoThe 7 layers are as follows :
1) Layer 1 - physical 2) Layer 2 - data link 3) Layer 3 - network 4) Layer 4 - transport 5) Layer 5 - session 6) Layer 6 - presentation 7) Layer 7 - application

Which layer of the OSI model are layers capabale of functioning?
The OSI Model stands for Open Systems Interconnection. The answer to the question which layer of the OSI model are layers capable of functioning is at all layers.
What term describes the process of adding headers to data as it moves through the layers of the OSI model?
encapsulation
What layer is supdivided into two sub layers in the OSI model?
Layer 2 is divided into the LLC and MAC sublayers.
Which model came first osi model or tcpip?
Offcourse osi..... TCP/IP is an implementation of osi....
How the OSI model layer can effect a network's design and networking in general?
the OSI model prescribes the steps to be used to transfer data over a transmission medium from one networked device to another. A layered model defines each layer separately. [ As long as the interconnections between layers remain constant, protocol designers can specialize in one area (layer) without worrying about how any new implementations affect other layers. ]
How do the layers of the OSI model correlate to the layers of the OSI model?
OSI
How many layer the Internet model consists of?
There are seven layers in OSI model.
Which layer of the OSI model are layers capabale of functioning?
The OSI Model stands for Open Systems Interconnection. The answer to the question which layer of the OSI model are layers capable of functioning is at all layers.
What are the top and bottom osi model layers called?
application -top of osi model physical- bottom of osi model
The OSI model has only five layers?
The OSI Model has 7 layers. Application Presentation Session Transport Network Data Link Physical
Role of osi model?
The OSI model acts as a standard in design of computer networks. It consists of total seven layers.
What layers of the OSI model does the NIC operate?
The NIC operates on Layer 2 (Data Link Layer) of the OSI Model.
How many layers of the osi model does the ping command test?
ping checks the physical -> data -> network layers. It uses ICMP
What types of layers are used in connection of two computers?
The seven layers of the OSI model.
Which one uses the greatest no of layers in the OSI model?
Router
Which uses the greatest number of layers in the osi model?
