The _ routing algorithms change their routing decisions to reflect changes in topology and usually the traffic as well.5. Stability is also an important goal for routing algorithms. The _ routing is also referred to as non-adaptive.3.
Each frame in the HDLC frame begins and ends with a _.14. Sending a packet to all destinations simultaneously is called _.13. The IEEE committee created Ten-Gigabit Ethernet and called it as _ Standard12.
A _ is a subset of the subnet that includes all the routers but contains no loops.19. Data link layer is split into _ and _ sub-layers.18.

Which Component of PPP is used for establishing, configuring, and testing the data-link connection?16.
File transfer applications, including e-mail and video, are delay-sensitive. This situation is called a _.23. When too many packets are present in (a part of) the subnet, performance degrades. Flow control relates to the point-to-point traffic between a given sender and a given receiver. In _ routing, we send messages to well-defined groups that are numerically large in size but small compared to the network as a whole.21.
Networks of nodes that just happen to be near each other are called _.29. Graph of the nodes (routers + hosts)28. At any instant of time, an ad hoc network can be described by a _.Ans.

A subnet mask should have _ for all bits that correspond to the network portion of the address.39. Which class of networks use subnetting?38. An organization cannot have a mixture of large and small networks to achieve higher utilization of address space. _ divides the address into a network prefix and local portion.36. Each Class C network address has a _ network-prefix with the three highest-order bits set to 1-1-0.35.
What is the minimum & maximum Size of the TCP Header?Ans. List the computer network application that uses UDP.50. In UDP protocol post _ through _ are registered posts.49. Symmetric release treats the connection as two separate unidirectional connections and requires each one to be released separately. RARP reply frame also consists of two fields they are _ & _.47. Reverse Address Resolution Protocol (RARP)46.
TCP protocol is a connectionless protocol. Congestion in a network or internetwork occurs because routers and Switches having _, _ that hold packets before and after processing.53. _ happens in any system that involves Waiting.52.

Which service primitive is used to exchanging data in connection-oriented services?61. In telnet what is the decimal code for the echo? _.60. In telnet Commands are always introduced by a character with the decimal code _ known as an Interpret as command (IAC) character.59. In _ way the telephone system works.58. List the ways by which Packet lifetime can be restricted to a known maximum value.56. The network can lose packets, store and duplicate packets these are the problems55.
FTP is a commonly-used protocol for exchanging files over any network that supports the _ protocol.67. Sendmail uses a _ system to manage inbound and outbound mail.66. _ is a command-line tool designed for most UNIX-like operating systems.65. The sender SMTP establishes a TCP connection with the destination SMTP and then waits for the server to send a _ Service ready message.64. The client SMTP uses the _ to determine the IP address of the destination mailbox.63.
PGP encrypts data by using a block cypher called _.Ans. Issues like authentication and non-repudiation can only be handled in the _ layer.72. State true or false: People authenticate other people by faces, voices, and handwriting70. The idea of having one-page point to another is now called _.69.
State true or false: Each page may contain links to other pages anywhere in the world.78. A vast, worldwide collection of documents called Web pages77. Because HTTP is a distributed information-based protocol, _ can improve the performance significantly.Ans. The HTTP communication is initiated by the _ requesting a resource on the origin server.75.
HTTP is a stateless protocol because of _.Ans. _ is responsible for servicing requests for information from Web browsers.80. Hypertext Markup Language (HTML) interpreter and HTTP client79.
