The difference between multilevel tdm multislot tdm and pulse-stuffed tdm?
they are all techniques used to handle a disparity/inequality in the i/p lines data rates.
1-Multilevel TDM.
it's used when the i/p lines data rates are multiple of each other.
for example if u have two i/p lines with data rate of 100kbps each
and another (third) i/p line with data rate of 200kbps
we multiplex the 1st two together (100k + 100k) to produce a data rate of 200kbps
2-Multislot TDM.
it's used to give a single i/p line two slots in the o/p frame, to do this we use a serial to parallel converter
for example if u have one i/p line with data rate of 200kbps
and another (second) i/p line with data rate of 100kbps
we apply serial to parallel converter on the 1st one to change into two i/p lines with data rate of 100kbps each
3-Pulse-Stuffed TDM
it's used when the i/p lines data rates are NOT multiple integers of each other
we make the i/p line with largest data rate the dominant one and add dummy bits to the other i/p lines data rates to be equal to it
for example if u have one i/p line with data rate of 100kbps
and another (second) i/p line with data rate of 99kbps
we make the 1st one the dominant one and add 1kbps of dummy bits to the second one (99k + 1k) to be equal the first one
What is the header format for FTP?
FTP does not have headers. The only response that the client gets from the server is: <code> <message>.
What is the meaning of network of networks?
This is usually used to describe the Internet.

I've been looking for the answer to the very same question myself, the best I've arrived at is that it isn't a question of "how do I become dedicated to ______", but "why do I want to be dedicated to ______". Don't look without but within. If what you're trying to dedicate yourself to is that important to you, by virtue of it being important to you, one ought to be at least emotionally dedicated to it, right? But maybe we're both just real lazy, or in my case lazy but at least smart enough to find some semi-philosophical reason to back away from that nasty 'D' word. Just keep digging, you're on the right track. Either way, I hope you figure it out. Oh, and if you do, let the world know about it-- I'll be listening. Hope this helps.
Network Interface Card
Its a card that you attach to your computer to interface( or access) network resources and the internet
What do you do if the are code manager says access denied when use the software upgrade?
There are a number of things to do if the area code manager says access denied when you use the software upgrade. You can start by confirming that you have the right code and then ensure that the upgrade is compatible with the system.
What is network communication?
communication network is a network of connecting the people to communicate with each other.

these r the aras on which it has made an impact.
Which combination is required to establish a connection to initially configure the Linksys WRT300N wireless access device?
a computer configured in the same IP subnet as the WRT300N and a direct cable connection to it
The Ping Of Death (shortened to POD) is when you ping someone with over 65,535 bytes of data. This causes the computer to experience a buffer overflow, thus crashing the computer. See also a ping flood
On the Internet, ping of death is a denial of service (DoS) attack caused by an attacker deliberately sending an IP packet larger than the 65,536 bytes allowed by the IP protocol. One of the features of TCP/IP is fragmentation; it allows a single IP packet to be broken down into smaller segments. In 1996, attackers began to take advantage of that feature when they found that a packet broken down into fragments could add up to more than the allowed 65,536 bytes. Many operating systems didn't know what to do when they received an over-sized packet, so they froze, crashed, or rebooted.
Which command is used by 65536 tcp port?
Ports are described by 16 bits. 2^16 is 65536 so the highest number is 65535 and port 65536 does not exist.
Servers
What is the wep key for bt home hub?
