Deck 4: Internet History and Architecture

Question 1

The problems of using IP numbers for addressing hosts in the Internet are resolved using

A)the concept of domains and the use of domain names.
B)the use of Telnet applications.
C)the use of email servers.
D)splitting IP addresses into four octets.
E)using fixed routing paths through the network.

Answer 1

A

Question 2

When using circuit switching,a dedicated path of transmission facilities is established between the communicating parties.

Answer 2

True

Question 3

The Domain Name System (DNS)is comprised of four elements.Which of the following is NOT one of these elements?

A)The domain name space
B)IP addresses
C)DNS database
D)Name servers
E)Resolvers

Answer 3

B

Question 4

The first "killer application" for the ARPANET was

A)Telnet.
B)FTP.
C)Email.
D)World-wide-web.
E)Remote login.

Question 5

In the Internet,individual hosts and/or local area networks are connected to an Internet services provider through a point-of-presence.

Question 6

A paradigm for electronic communications where a dedicated path is opened and maintained during the exchange is called

A)message switching.
B)circuit switching.
C)packet switching.
D)data switching.
E)analog switching.

Question 7

The National Science Foundation was responsible for many of the policy decisions that led to the modern Internet.

Question 8

The key features of the DNS database are

A)variable-depth hierarchy for names,distributed databases,and name servers.
B)Resolvers,distributed databases,and name servers.
C)Distribution controlled by the database,resolvers,and distributed databases.
D)Domain name spaces,name servers,and variable-depth hierarchies.
E)Variable-depth hierarchy for names,distributed databases,and distribution controlled by the database.

Question 9

Hosts connected to the Internet are identified by a unique 24-bit number that identifies a network and specific host within that network.

Question 10

When using message switching instead of packet switching,a dedicated path must be established between the parties for all messages that are sent.

Question 11

The Internet grew out of a Department of Education project.

Question 12

A paradigm for electronic communications where messages are split into blocks of data with limited size,which are then transmitted one-by-one across the network is called

A)message switching.
B)circuit switching.
C)packet switching.
D)data switching.
E)analog switching.

Question 13

Commercial use of the Internet was discouraged until approximately 1988.

Question 14

Packet switching is like message switching except that the unit of data sent at one time is limited in size,thus requiring larger messages to be broken into pieces.

Question 15

The first two important applications developed for the ARPANET where

A)Telnet and FTP.
B)Telnet and email.
C)Telnet and world-wide-web.
D)FTP and email.
E)Email and world-wide-web.

Question 16

A computer connected to the Internet is called a host.

Question 17

The development of a internationally distributed collection of multimedia files addressed using universal resource locators led to the

A)Telnet package.
B)Email system.
C)World-wide-web.
D)FTP package.
E)Domain resource locator.

Question 18

ARPANet was the first message-switching network .
