AMCAT Computer Networks Quiz-1

OSPF (Open Shortest Path First) is a link-state routing protocol that uses the Dijkstra algorithm to find the shortest path between two nodes in a network. It is widely used in large enterprise networks because it is highly scalable and can handle complex topologies.

Hypertext transfer protocol is referred to as HTTP.It serves as the basis for data communication on the web.This protocol specifies the message's format, transmission method, and other details.

Real-time session initiation, maintenance, and termination are all functions of the signaling protocol SIP.
Signaling and managing multimedia sessions are done via SIP.

Base64 is frequently used in a variety of applications, such as email via MIME and XML storage of complicated data.
Because bits in regular binary data can be interpreted incorrectly by underlying protocols and result in inaccurate data being sent to a network, we employ this code instead.

The application layer protocol known as SMTP stands for Simple Mail Transfer Protocol.
When a client wants to send an email, the client first establishes a TCP connection to the SMTP server before sending the email via that connection.

The protocols used by email include SMTP, IMAP, and POP.
SMTP is the most often used one at the application layer.

Telnet is used for accessing remote computers. Using telnet a user can access a computer remotely. With Telnet, you can log on as a regular user with whatever privileges you may have been granted to the specific application and data on the computer.

RIP (Routing Information Protocol) is a distance-vector routing protocol that uses the Bellman-Ford algorithm to find the shortest path between two nodes in a network. It is a simple protocol that is widely used in small networks, but it can be slow to converge and may not be suitable for large or complex networks.

CSMA/CD works with collision detection after a collision has already happened, whereas CSMA/CA deals with collision prevention.
Carrier Sensing Multiple Access/Collision Detection is referred to as CSMA/CD.
Carrier Sensing Multiple Access/Collision Avoidance is referred to as CSMA/CA.
The adoption of these protocols enables effective multiple channel access.

The acknowledgment is briefly delayed when using the piggybacking approach in order to be attached to the subsequent outgoing data frame.
The channel bandwidth is greatly reduced because in non-piggybacking systems, some bandwidth is set aside for acknowledgement.
