* LLC sublayer(802.2): responsible for identifying different protocol logically & encapsulate them.
Which layer of the OSI reference model is responsible for signal encoding?

What are the limitations of distributed control system?
Loading this system can sometimes take a while because of all the information. If you can deal with it being a little bit slow, you have a great program.
Compare and contrast the advertisements by RIP and OSPF?
RIP is an Interior Gateway Protocol and the most widely accepted routing protocol. It is also known by the name of the Unix daemon program routed. RIP is straightforward: it arranges to have routers to broadcast their entire current routing database periodically
OSPF is a link-state algorithm. OSPF specifies a class of messages called link-state advertisements (LSAs) that allow routers to update each other about the LAN and WAN links to which they are connected. When a change is made to the network, LSAs flow between routers.
OSPF routers receive link-state updates and store them in a topology database in memory.
OSPF networks as an end-station-to-router protocol. OSPF addresses all the deficiencies of RIP, without affecting connectivity to RIP based networks.

How long should a 2wire modem last?
A good general rule is that any electronic is only *designed* to last for the duration of it's warranty, and not much longer.

Which IPv4 to IPv6 transition methods allows an IPv4 only host to communicate with a IPv6 only host?
I guess NAT64
What is the bandwidth of a signal that ranges from 40KHz to 4 MHz?
Solution
Let fh is the highest frequency and fl is the lowest frequency.
Bandwidth = fh - fl = 4000 - 40 KHz = 3960 KHz = 3.96 MHz
In future if everyone has home network connected to a computer terminal what is the disadvantage?
The only disadvantage will be internet speed.

Why dots are used to separate ip addresss?
Up until about five years ago, when there were enough Internet addresses for all those who needed them, Internet Addresses were written - 123.456.89. The people realised that the available range of addresses would run out very quickly when mobile phones, cars, refrigerators, etc all had their own Internet Addresses. So a new more expandable system was devised that had Internet Addresses now written as AA:12:BC:17:NM:01:JJ:89.
What happens when part of a message using tcp is not delivered to the destination host?
The part of the message that is missing is retransmitted.
What is the default password on shaw routers?
