MCQs on OSI Model Questions :-   (Q1). OSI Model consists of _ _ _ _ _ layers. seven two five four (Q2). The physical layer is concerned with the transmission of _ _ _ _ _ over the physical medium. Programs Protocols Bits Dialogs (Q3). The main responsibility of the _ _ _ _ _ layer is to deliver packets from source to destination. Network Application Transport Physical (Q4). Segmentation and reassembly are functions of the _ _ _ _ _ layer. Session Transport Presentation Application (Q5). Trailers to the data are added only at _ _ _ _ _ layer of the OSI model. Presentation Physical Network Data link (Q6). Frames are prepared by _ _ _ _ _ layer. Physical Data link Network Transport Answers :- I will not tell/show the answer's of the above Questions now.

Open system Interconnection  (OSI) Model - 1 Open System Interconnection (OSI) Model  :-            Open System Interconnection (OSI) Model was developed by the International Standards Organization (ISO) describes the flow of information from one computer to another. OSI model is also called ISO OSI Reference Model. It is conceptual model that has seven layers. Physical, Data link, Network, Transport, Session, Presentation and Application are the seven layers of OSI model. Each layer performs distinct functions on the data in accordance with the precious layer functions. The application, presentation and session layers are called as Upper layers.  7 layers of OSI model           All the layers of the OSI reference model use different protocols. Protocol defines the procedure that is to be followed during data transmission. It is the set of specified rules and standards used to transmit data fr...

Internet Protocol Address (IP address) - 2 Summary on What we have studied in last Tutorial ? :- An IP address is a Unique Address assigned to a device in a network. An IP address is a 32 bit address which is divided into various Classes, Class A, Class B, Class C, Class D, and Class E. To make the IP address easier to read and interpret, they are written in decimal format where a point is separated by a  Byte. (2.1) Class A IP Addressing   :-             Class A consists of 8-bit Network ID and 24-bit Host ID, as show in the figure below;          So, each network in class A  will have  2 24  -2 = 16,777,214  number of host (IP) addresses available to assign to the devices except for two reserved host addresses in each network. Class A can be divided into 128 network blocks (  number of Networks ) where the first...
