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>.
Network Interface Card

What is the meaning of network of networks?
This is usually used to describe the Internet.
A few computers connected together is a computer network.
A few computer networks connected together is a network of networks.
1. DHCP was designed to replace the older BOOTP
2. BOOTP can only provide an IP to a computer while it is booting while DHCP can provide an IP when the OS is already loaded
3. DHCP is primarily used to seamlessly provide IP addresses to computers while BOOTP is used to configure and boot diskless computers or thin clients
4. BOOTP has a 30 day lease on the IP address as a default while DHCP only sets 8 as a default
5. DHCP can automatically rebind or renew their leases while BOOTP requires a system restart
Flip Flop
Any computer or electronic device that is used to serve up digital music through a network or over wireless to end devices or "clients" would be considered an Audio Server. In general terms this could be anything from a home stereo to a more complex home theater PC (HTPC), to the system of computers that would power a massive audio distribution company's online website - like the cluster of computers needed for Apple's iTunes store.
What is the difference between RFC 821 and RFC 822?
rfc821 is for SMTP
rfc822 is for mail message format..
The ping utility allows users to test if a host can be reached on an IP network, as well as the round-trip time for messages from a host to a destination. Response times are generally tracked in milliseconds.
What do you do with a Mac address?
The Media Access Control - MAC Address is a number, created by the manufacturer, which identifies your computer on a network. If you have a wireless network, for example, you may want to add the MAC address for each computer you want to connect to the network, and tell the router to only allow these computers to connect, to prevent unknown computers connecting to your network.
Why you are using thick size of feeder cable in tele network?
why we are using thick size of feeder cable in tele network?
Huffman Coding is a method of shortening down messages sent from one computer to another so that it can be sent quicker.
Is network and IP address the same?
its different......basically.network contain hosts can be server or workstation each has unique adddress (thats ip address) to communicate each other
