Q

refers to a TCP/IP protocol that enables the sharing of computer programs and/or data between hosts over a TCP/IP network. It uses TCP to create a virtual connection for control information and then creates a separate TCP connection for data transfer

A

file transfer protocol (FTP)

20
Q

refers to a TCP/IP protocol that enables computers to mount drives on remote and operate them as if they were local drives,

A

network file system (NFS)

21
Q

refers to a TCP/IP protocol that is used on the Internet for translating names of domains and their publicly advertised network nodes into IP addresses

A

domain name system (DNS)

22
Q

refers to a TCP/IP protocol that monitors and controls the exchange of management information between networks and network components; it enables network administrators to manage configurations, statistics collection, network performance, and security

A

simple network management protocol (SNMP)

23
Q

3 components of SNMP

A

managed devices
agent
NMS

24
Q

refers to a TCP/IP protocol that uses the TCP as the transport protocol to establish a connection between server and client,

A

terminal emulation protocol network (telnet)

25
Q

a connection using telnet is called

A

virtual terminal (VTY) session, or connection

26
Q

a UNIX command that allows authorized users to log in to other UNIX machines (hosts) on a network and to interact as if the user were physically at the host computer. Once the user is logged into the host, the user can do anything that the host has permitted, such as read, edit, or delete files

A

remote login application (rlogin)

27
Q

refers to an application-level protocol service and an Internet standard developed by the IETF that supports the exchange of information on the World Wide Web, as networks

A

hypertext transfer protocol (http)

28
Q

is a secure message-oriented communications well as on internal protocol designed for use in conjunction with HTTP

A

hypertext transfer protocol over secure socket layer (https)

29
Q

a security protocol that works at a socket level. This layer exists between the TCP layer and the application layer to encrypt/decode data and authenticate concerned entities.

A

secure sockets layer (SSL)

30
Q

refers to a connection-oriented TCP/IP standard transport layer protocol that provides reliable data delivery, duplicate data suppression, congestion control, and flow control on which many application protocols depend

A

transport control protocol (TCP

31
Q

used to deliver information from one port to another and thereby enable communication between application programs

A

TCP

32
Q

refers to a connectionless TCP/IP standard transport layer protocol that provides unreliable, best-effort service

A

user datagram protocol (UDP)

33
Q

protocol that sends independent packets of data, called datagrams, from one computer to another with no guarantees about arrival

A

UDP

34
Q

identifies the application that sends the segment. This field is 16 bits long

A

source port

35
Q

identifies the application that receives the segment. This field is 16 bits long.

A

destination port

36
Q

refers to every byte of data sent over a TCP connection. The value of this field is equal to the sequence number of the first byte in a sent segment. This field is 32 bits long.

A

sequence number

37
Q

indicates the sequence number of the next segment’s first byte that the receiver is expecting to receive. The value of this field is 1 plus the sequence number of the last byte in the previous segment that is successfully received. This field is 32 bits long

A

acknowledgement number

38
Q

indicates the length of the TCP header. The unit is 32 bits (4 bytes), if there is no option content, the value of this field is 5, indicating that the header contains 20 bytes

A

header length

39
Q

this field is always set to 0 as it is intended for future protocol changes. It is 6 bits long.

A

reserved

40
Q

include FIN, ACK, and SYN flags which indicate the TCP data segments in different states.

A

control bits

41
Q

used for TCP flow control. The value is the maximum number of bytes that are allowed by the receiver

A

window

42
Q

is a mandatory field in which it is calculated and stored by the sender and verified by the receiver

A

checksum

43
Q

specifies the total length of the UDP header and data. The possible minimum length is 8 bytes because the UDP header already occupies 8 bytes

A

length

44
Q

specifies the total length of the UDP header and data. The possible minimum length is 8 bytes because the UDP header already occupies 8 bytes

A

checksum

45
Q

a method, in which the sender and the receiver inform their respective initiated before the actual operating systems that a connection will be data communication begins

A

three-way handshake

46
Q

fields to Implement reliable and ordered data transmission

A

sequence number and acknowledgement number

47
Q

requires the sender to receive an acknowledgment from the receiver after transmitting a certain amount of data.

A

window sliding mechanism
