What is the difference between network layer and network layer protocol?
A network layer refers to one of the actual 7 layers. The network layer protocol is actually the system it uses, possibly the order that the layers are done by?
Which layers in the Internet protocol stack does a router process?
from 1 through 3
What three layers of the OSI model are used by the X25 protocol?
Session, transport and network
The process of combining multiple outgoing protocol streams at the Transport and Network layers in TCPIP is called?
Multiplexing
When connectionless protocols are implemented at the lower layers of the OSI model?
an upper-layer, connection-oriented protocol or service
What is the difference between GMLAN and CAN 500K protocol used in ford vehicles?
CAN protocol comprises only of PHYSICAL and DATA LINK LAYER when mapped with the ISO/OSI standards. Higher layers specific to the application can be built over this basic layer. But this is not mandated unless required. GMLAN on the other hand uses CAN protocol. But it also mandates the use of TRANSPORT layer, NODE MANAGEMENT layer, NETWORK MANAGEMENT layer and INTERACTION layer on top of CAN protocol. It can be mapped to the ISO/OSI model completely. 500k CAN used in Ford vehicles will definitely have higher layers equivalent to those of GMLAN. Only the structure of higher layers might differ in the two protocol. Rest the same.
Why is data protocol used?
data protocol is used to route the data from the source to destination, and it is also used for congestion control, flow control & error control in the data that is being transmitted........... data protocol is responsible for the end to end delivery of the data, which may be in the form of messages, frames, packets across the different layers of the protocol architecture....
What is the protocol originally designed for IBM to provide transport and session layers services for applications running on small homogenous networks?
NetBIOS
Why does OSI model has exact seven layers?
Because it was developed that way. Nowadays, layer 2 is sometimes divided into 2 "sub-layers", and the MPLS protocol is considered to be between the layers 2 and 3, and is therefore sometimes called "layer 2.5", but the traditional 7 layers are usually maintained as the "official" layers. We might say this is for historical reasons.
What application layer protocol is required when website appears on computer screen?
Application protocol layers that are specific to certain applications such as the World Wide Web (WWW), email, and FTP causes websites to appear on the computer screen.
What is the CANopen communication protocol used for?
CANopen is a communication protocol and device profile specification. It is used for embedded systems in automation. CAN stands for Controller Area Network and is the lower level protocol implementing the data link and physical layers. Profiles for more specialized devices can be built on top of this basic profile.
Why is the ping test also called testing the protocol stack?
Because it tests connectivity at Layers 3, 2, and 1 of the OSI model.
