PROTOCOLS AND STANDARDS
In this section, we define two widely used terms: protocols and standards. First, we define protocol, which is synonymous with rule. Then we discuss standards, which are agreed-upon rules. Protocols…
KEY TERMS in Computer Networks
Following are some important terms, which are frequently used in context of Computer Networks. TermsDefinition1. ISOThe OSI model is a product of the Open Systems Interconnection project at the International…
Comparison of OSI and TCP/IP Reference Model
Now it's time to compare both the reference model that we have learned till now. Let's start by addressing the similarities that both of these models have. Following are some similarities between…
The TCP/IP Reference Model
TCP/IP means Transmission Control Protocol and Internet Protocol. It is the network model used in the current Internet architecture as well. Protocols are set of rules which govern every possible communication over…
Application Layer – OSI Model
It is the top most layer of OSI Model. Manipulation of data(information) in various ways is done in this layer which enables user or software to get access to the…
Presentation Layer – OSI Model
The primary goal of this layer is to take care of the syntax and semantics of the information exchanged between two communicating systems. Presentation layer takes care that the data is sent in such…
Session Layer – OSI Model
The Session Layer allows users on different machines to establish active communication sessions between them. It's main aim is to establish, maintain and synchronize the interaction between communicating systems. Session…
Transport Layer – OSI Model
The basic function of the Transport layer is to accept data from the layer above, split it up into smaller units, pass these data units to the Network layer, and…
Network Layer – OSI Model
The network Layer controls the operation of the subnet. The main aim of this layer is to deliver packets from source to destination across multiple links (networks). If two computers…
Data Link Layer – OSI Model
Data link layer performs the most reliable node to node delivery of data. It forms frames from the packets that are received from network layer and gives it to physical…
