Comparison of OSI and TCP/IP Reference Model

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 OSI Reference Model and TCP/IP Reference Model. Both have layered architecture. Layers provide similar functionalities. Both are protocol […]

The TCP/IP Reference Model

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 a network. These protocols describe the movement of data between the source and destination or the internet. They also offer simple […]

Application Layer – OSI Model

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 network. Some services provided by this layer includes: E-Mail, transferring files, distributing the results to user, directory services, network resources, […]

Presentation Layer – OSI Model

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 a way that the receiver will understand the information(data) and will be able to use the data. Languages(syntax) can be […]
