Download AMCAT OSI, TCP/IP layers and protocols Questions 2021 (AMCAT Computer Science): There are so many candidates who refrain from attempting Computer Science section in AMCAT considering it as non mandatory. But to emphasize, it is that module which attracts the attention of recruiters. So to grace the profile with good scores in Computer Science, always increases the chances of selection and immediate calls. All the big daddies of IT industry like Cognizant, Accenture, Infosys, Wipro, etc. count AMCAT score as a major standard and parameter for hiring. Hence below we bring you AMCAT OSI, TCP/IP layers and protocols Questions for practice in Computer Science.
Download AMCAT OSI, TCP/IP layers and protocols Questions 2021
For the engineering candidates, especially of Computer Science branch, must take up AMCAT Computer Science module. It covers questions from basics of operating system and computer architecture, computer networks and database concepts. It consists of 26 questions to be completed in 25 minutes. From the topic OSI, TCP/IP layers and protocols, mostly 2 to 3 Questions come. The difficulty level ranges from average to tough. It can take about 1 to 1.5 minutes to solve the questions specific to this section.
About OSI, TCP/IP layers and protocols
- Application layer : This layer is the closest to the user. It enables network applications to communicate with other network applications.
- Presentation layer : It defines data formats. Compression and encryption are defined at this layer.
- Session layer : It defines how to establish and terminate a session between two systems.
- Transport layer : It performs segmentation of great chunks of data received from the upper layer protocols. Also, it establishes and terminates connections between two computers. Used for flow control and data recovery.
- Network layer : It works on device addressing, routing, and path determination. Device (logical) addressing is used to identify a host on a network (e.g. by its IP address).
- Data link layer : It encapsulates a packet in a frame. A frame contains a header and a trailer that enable devices to communicate. A header, most commonly, contains a source and a destination MAC address. A trailer contains the Frame Check Sequence field, which is used to detect transmission errors.
- Physical layer : It decides how to move bits from one device to another. Also, it works on how cables, connectors and network interface cards would interact and send and receive bits.
It consists of four layers: Network Access, Internet, Transport, and Application.
|TCP/IP Model||OSI Model|
|Application layer||Application, Presentation and Session layer|
|Transport layer||Transport layer|
|Internet layer||Network layer|
|Network access layer||Data Link and Physical layer|
