What is the difference between ISDN and SS7?
The Integrated Services Digital Network (ISDN) uses Digital Subscriber Signalling System No. 1 (DSS1) protocol interfaces to connect subscribers to the network. These are User-to-Network (UNI) interfaces.
Signalling System No. 7 (SS7) is a suite of signalling protocols used in Network-to-Network (NNI) interfaces. These are connections between network elements within the ISDN.
What are the address ranges of private IP addresses?
10.0.0.0 10.255.255.255
172.16.0.0 172.31.255.255
192.168.0.0 192.168.255.255
An IP address is basically a unique identifier of computers and/or networks linked to the internet.
You can find your ip using the following websites:

POP is Post Office Protocol .This protocol is used in receiving of mails fro mail server.
In a question this general, the only way to answer without pages of nonspecific information about potentially hundreds of issues is to say: Most likely the problem lies with the host or with your use of the host.
Trouble shooting questions to ask to get started:
Can other people access the application?
If yes, then it is on your end.
If no, then it is on the host end.
Well, a shared resource is something that is like a natural resource but it is shared so that makes it a "Shared Resource".

When your computer is connected your whole network become slow?
Check and make sure your not torrenting or doing anything network intensive. You might have a program running that is using up the network or a virus.
Internet Router has a high pitch sound?
quite a number of routers either have this fault straight out the box or develop it after some time. I have seen it in all major brands of warying types and function.
It varies in intensity from barely audible to quite loud in some cases, and is usually ranges from between 8-20khz. It may vary in tone and volume with load or traffic, or it may be constant. Most people believe it is the power supply unit (adaptor) or induction coil that has come lose, but this is actually inaccurate. Most of the time this is a semiconductor problem that cannot be cured.
Your main options are 1.) if it is a new device, return it and get it replaced. 2.) If it is an older device out of warranty you could relocate it to another room, or cupboard under the stairs (or similar) where it won't be such an issue. 3.) you could replace the unit. (expensive yes) but quite often these high pitched noises cause irritation, distress and headaches sometimes without the user even realising the router is the cause. 4.) you could enclose it in a ventilated sound dampened enclosure, though I reiterate it must be ventilated uless you're happy of running the risk of setting your home on fire. 5.) smash it with a sledgehammer for satisfaction, especially if (as in option 3) you have been distressed by the noise.
Most of the components that cause the issue are surface mounted and not easily replacable. I have seen too many people guessing/speculating about the cause of this problem but RARELY is it a power supply or induction coil or any other component that a standard electronic serice engineer would be prepared to fix.
Is Multiplexer acts as not gate?
f = ~s.a + s.b , thus is the function for a multiplexer. let a not gate with input x and output y. set a = 1 and b =0 to get a not gate. y = ~x.1 + x.0
How can you reset Netgear router WGT624v3 at 192.168.1.1 when admin and password won't get in?
If its your home computer you should be able to just unplug the power to the router and wait 15 seconds or so then plug power back in. It will have no choice but to reset itself. If its a company computer make sure its ok to turn off power to the router before you unplug it.(ask the admin)(or you could screw up any up/down-loads going on).
Are symbols and pictures examples of input or output devices?
no but the key board used to type letters is an input device , the mouse used to select symbols and the scanner used to store digital information of pictures are input devices
The purpose of animal breeding is to genetically improve the economic merit of livestock. Usually many traits (5-30), for example milk yield and disease resistance, are grouped under economic merit measure. Selection on these traits is weighted in a selection index rather than on profit directly.

Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
How many UDP packet send in traceroute function?
... as always ... it depends, but when issuing the command from a *nix OE and not specifying the -I option or others manipulating default settings, it will typically send 3 datagramms for each TTL value, where TTL values start with 1 and ends with 30.
Therefore the answer is 90 packets.
You will notice, that every datagramm is send with a unique destination port, typically starting with port 33435.
Why is Synchronization a problem in data communication?
synchronization between the multiplexer and demultiplexer is a major issue in data transmission. if the multiplexer and demultiplexer are out of synchronization a bit belonging to one channel may be received by the wrong channel. for dis reason , one or more synchronization bits are usually added to the beginning of each frame. these bits, called framing bit , follow a pattern, frame to frame, that allow the demultiplexer to syncronize with the incoming steam so that it can separate the time slots accurately. in most cases, this syncronization information consists of one bit
