Interconnection of devices to enable resource sharing.
Network
Set of rules/instructions
Protocol
Protocols that can only be run by the vendor that developed it.
Proprietary Protocol
model is a conceptual model created by the International Organization for Standardization which enables diverse communication systems to communicate using standard protocols.
Open System Interconnection (OSI)
provides a standard for different computer systems to be able to communicate with each other.
Open System Interconnection (OSI)
can be seen as a universal language for computer networking. It’s based on the concept of splitting up a communication system into seven abstract layers, each one stacked upon the last
Open System Interconnection (OSI)
This is the only layer that directly interacts with data from the user.
Application Layer
responsible for translation, encryption, and compression of data.
Presentation Layer
The time between when the communication is opened and closed is known as the session.
Session Layer
is also responsible for flow control and error control.
Transport Layer
performs error control on the receiving end by ensuring that the data received is complete, and requesting a retransmission if it isn’t.
Transport Layer
is a crucial component of the networking stack. Its primary function is to facilitate communication between devices across different networks by providing logical addressing, routing, and forwarding of data packets.
The Network Layer
facilitates data transfer between two devices on the SAME network.
The Data Link Layer
includes the physical equipment involved in the data transfer, such as the cables and switches.
