TCP 3-way Handshake Summary Cheatsheet

Cloud Computing

Cloud Computing is an approach to offer IT Services to customers remotely is called Cloud Computing. It is the practice of using IT & Network which are physically hosted in a remote location (mostly on the Internet) to store, manage and process data, rather than a local server or a personal computer. It is the […]

IP Address & its Types

“A unique identity number which is used to identify Network Devices & communication between these devices” IP Address is a logical numeric address that is assigned to every single computer, printer, switch, router or any other device that is part of a TCP/IP-based network. The IP address exists in every network, even only a pair […]

Network Topology Types

“The layout pattern & connectivity scheme between the devices in a network is called network topology”. It is a virtual shape or structure of the network. Devices on the network are called as nodes. The most common nodes are computers and peripheral devices. Network topology is a virtual illustration of these nodes and their connections […]

TCP 3-way Handshake Process

TCP (Transmission Control Protocol) is “a Connection Oriented Transport Layer (Layer4) protocol for reliable communication between network devices” TCPv4 was published in RFC-793 in 1981 and is still the current version. TCP is a connection oriented full-featured transport layer protocol that provides all the functions needed by a typical application for the reliable transportation of data […]

TCP/IP Model

“ TCP/IP Model is a standard reference Model for conceptualising data communications between networks ” The TCP/IP is a practical Model that provides E2E data communication specifying how data should be packetized, addressed, transmitted, routed, and received. It characterizes and standardizes the communication functions of a Network system without regard to its underlying internal structure […]

07. Application Layer of OSI Model (Layer7)

The last layer of OSI Model, the Application Layer is responsible for End user Network Applications. It is the 7th & highest Layer in the 7Layer OSI Model. This is the layer where real traffic data is generated in most of the cases. This could be a web request generated from HTTP protocol, a command […]

06. Presentation Layer of OSI Model (Layer6)

As the name points, Presentation Layer is responsible for representation & formatting of data for session Layer in Encapsulation Process. It is the 6th Layer in the 7Layer OSI Model after Session Layer. It serves like a translator & takes care that the data is sent in such a way that the receiver will understand […]
