Module 5 - MBA 703 (Sadhya) UPDATED ACTUAL Questions
and CORRECT Answers
Advanced Research Projects Agency (ARPA) A U.S. Department of Defense agency that created the first global computer
network.
Created in response to Sputnik launch to ensure that the US would not be
surprised again.
ARPANET A computer network developed by the Advanced Research Project Agency (now
the Defense Advance Research Projects Agency) in the 1960s and 1970s as a
means of communication between research laboratories and universities.
ARPANET was the predecessor to the Internet.
Goal was to allow different computers located around the country to be
integrated together into one network
Transmission Control Protocol/Internet Protocol (TCP/IP) Solved the problem of early telecommunications networks (internet precursors)
of not allowing organizations connected to one network communicate with
another network
was designed to allow networks running on different protocols to have an
intermediary protocol that would allow them to communicate
A protocol suite
Internet "an interconnected network of networks"
Created when TCP/IP became a standard protocol allowing networks to
communicate with one another.
, Packet The fundamental unit of data transmitted over the
Internet
Each has the sender's address, the destination address, a sequence number, and a
piece of the overall message to be sent.
Different ones in a single message can take a variety of
routes to the destination and they can arrive at different
times. For this reason, the sequence number is used to
reassemble them in the proper order at the destination.
Switch A network device that connects multiple hosts together
and forwards packets based on their destination within the local network which is
commonly known as a Local Area Network (LAN).
Router A device that receives and analyzes packets and then
routes them towards their destination.
used to connect one network to another network
IP Address Every device on the Internet (personal computer, a
tablet, a smartphone, etc.) is assigned a unique identifying number
Domain Name a human-friendly name, convenient for remembering a website.
generally consist of a descriptive word followed by a dot (period) and the Top-
Level Domain (TLD)
DNS "domain name server or system."
acts as the directory of websites on the Internet.
When a request to access a host with a domain name is given, this server is
queried. It returns the IP address of the host requested, allowing for proper
routing
Packet-switching When a message's packets are sent on the Internet, routers try to find the optimal
route for each packet. This can result in packets being sent on different routes to
their destination. After the packets arrive, they are re- assembled into the original
message for the recipient.
Protocol the set of rules that govern how communications take place on a network
Growth of the internet in the 1980s the early popularity of the Internet was driven by the use of electronic mail
Prior to this is was used primarily from government, academic and research
organizations.
