ALREADY GRADED A+
What are the major differences between circuit- switched,
packet-switched, and IP-based communications? -
....ANSWER...Circuit-switched - old POTS lines, support
real-time communications without much delay, full
integrity, no collision, transmit full message. Expensive
due to circuit per conversation until terminated and
network carriers need to charge for that amount even if
the line isnt used
How does IP-based communication work in today's
networks? - ....ANSWER...Devices communicate using
IP addresses, and data is transmitted in packets over
networks, primarily using the TCP/IP protocol suite.
What is the difference between routing and switching in
network technology? -
....ANSWER...Routing: Involves directing data between
1
,different networks. (over IP addresses)
Switching: Involves directing data within the same
network. (over MAC address)
What is the IEEE 802.3 standard, and what are its
specifications? - ....ANSWER...Defines the standards for
ethernet connection data-link layer and physical layer,
MAC address and RJ 45 ethernet cable
What is the difference between IPv4 and IPv6? -
....ANSWER...Ipv4 is 32 bits and its for private, ipv6 is
public ip 128 bits
What is the difference between the Internet and the
World Wide Web? - ....ANSWER...Www is the web/
websites vs the internet is the network that connects ur
device to these webpages
This individual is credited with inventing the World Wide
Web. Who is he? - ....ANSWER...Tim berners lee
What is the difference between connectionless and
connection-oriented communications? -
....ANSWER...TCP is connection oriented and is good
when sending a lot of messages to one person or host but
will take longer to set up
2
,UDP is connectionless and is good when sending
occasional messages to one or multiple hosts
which OSI model transport layer protocol uses
connectionless protocol to sends simple broadcast
messages
A TCP
B UDP
C IP
D PPTP - ....ANSWER...UDP
3
, what is the address size of IPv6 addresses
32 bits
64 bits
128 bits
256 bits - ....ANSWER...128 bits
private IP range - ....ANSWER...10.0.0.0 to
10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255
NDP (Neighbor Discovery Protocol) -
....ANSWER...similar to ARP(address resolution protocol)
for IPv4
TTL (Time to live) - ....ANSWER...one of the IP header
values
Which application architecture is the only architecture in
which all processing functions occur on the client?
4
