ISDS 705 Module 5 exam with complete
solutions
packet - ANSWER-The fundamental unit of data transmitted over the Internet.
When a host (PC, workstation, server, printer, etc.) intends to send a message
to another host (for example, your PC sends a request to YouTube to open a
video), it breaks the message down into smaller pieces, called packets. Each
packet has the sender's address, the destination address, a sequence number,
and a piece of the overall message to be sent. Different packets 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
the packets in the proper order at the destination.
switch - ANSWER-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 - ANSWER-A device that receives and analyzes packets and then routes
them towards their destination. In some cases, a router will send a packet to
another router. In other cases, it will send it directly to its destination. Routers
are used to connect one network to another network
IP address - ANSWER-Every device on the Internet (personal computer, a tablet,
a smartphone, etc.) is assigned a unique identifying number called an IP
(Internet Protocol) address. Originally, the IPv4 (version 4) standard was used.
It had a format of four numbers with values ranging from 0 and 255 separated
by a period.
domain name - ANSWER-a human-friendly name, convenient for remembering
a website. These names generally consist of a descriptive word followed by a
dot (period) and the Top-Level Domain (TLD). For example, Wikipedia's domain
name is wikipedia.org

DNS - ANSWER-"domain name server or system." DNS acts as the directory of
websites on the Internet. When a request to access a host with a domain name
is given, a DNS server is queried. It returns the IP address of the host
requested, allowing for proper routing.
Packet-switching - ANSWER-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 - ANSWER-the set of rules that govern how communications take
place on a network. For example, File Transfer Protocol (FTP) are the
communication rules for transferring files from one host to another. TCP/IP,
discussed earlier, is known as a protocol suite since it contains numerous
protocols.
Web 2.0 - ANSWER-Universal access to Apps
•
Value is found in content, not display software
•
Data can be easily shared
•
Distribution is bottom up, not top down
•
Employees and customers can use access and use tools on their own
•
Informal networking is encouraged since more contributors results in better
content
