What is Maximum data rate of binary signals on a noiseless 3khz channel is?
Nyquist theorem for noiseless channel
C= 2Blog22n.
C= channel capacity in bps
B= bandwidth in KHz
1 KHz= 1000 Hz
C= 2*3*1000*log22.
=6000 * log2 2.
=6000
=6000 bps

What to do if the UDP receives datagrams that are not in sequence?
Since, there is no error checking in UDP. Datagrams will be passed to the next OSI layer without rearranging or in the order by the same which was received and it will not be dropped.
What are the disadvantages and advantages to using cat 3 cable for Ethernet?
advantage: it is really cheap.
disadvantage: the top speed is only 10 Mbps
Network analysis by linear programming and shortest route?
Since you mentioned shortest route, by network analysis I assume that you mean analysing the min and max lengths of a path through a given graph/network. The simplest shortest route algorithm is Dijkstra's algorithm and is as follows:
1. mark all nodes as unvisited, and set total length of each node as infinity, except the initial/starting node which should be marked 0 and current.
2. travel along the current node's shortest adjacent arcto an unvisited node.
3. add the arc's length and the previous node's total length to the current nodes total length, and then mark the current node as current and the previous node as visited.
4. repeat 2 and 3 until you reach your target node.
The algorithm for longest path is the same except in step two you follow the node's longest adjacent arc.
For the linear programming of this visit the related link below this answer.
What is a component switch used for?
A component switch is used with electronics and wiring. You can wire electronics to turn on using a switch with multiple linked to one. A component switch is the overall central one that they all link to and function off of.
You cannot ping specific ports as they are not designed to respond to this type of protocol. Each port can be checked for an open or close state.
How do you make my PRONET wireless router password protected?

Choose password and enter in the same
Close and reboot.
How explain the terms even parity and odd parity Is one method bettrer than the other?
"Parity" refers to the number of 1s in a given binary number. Odd parity means there are an odd number of 1s and even parity means that there are an even number of 1s.
Parity bits are often used as a crude means of error detection as digital data is transmitted and received.
For example,
0b11010100 has 4 1s in it, therefore, it has even parity.
Two devices exchanging data must be set to the same parity. If both are set (strapped) for odd parity, for example, then the sending device must ensure that the number of bits in each word has an odd number of 1s. Likewise, the receiving device must be set to ensure it only receives words with an odd number of 1s.
An odd parity bit is defined as a bit in the word which can be set to ensure odd parity. If the word already has an odd number of 1s, then the parity bit is not set. If the word otherwise has an even number of 1s, the parity bit is set to ensure an odd number of 1s.
The same is true for even parity settings. One way is not necessarily better than the other in theory but, in practice, should observe the convention for the system in question.
Many (if not most) devices provide a connector pin that can be strapped to define either even or odd parity.

What is the purpose of the monitor?
What Is the Purpose of a Monitor? By James Walker, eHow Contributor
It doesn't matter how powerful or how fast your computer is. Without a monitor, it is useless. There are many kinds of monitors out there, and they all have very different functions. Knowing what purposes monitors serve in everyday life can go a long way in helping you decide what kind to look for when it's time to replace the one you're reading this on.
- Basic FunctionWatching Movies
- The basic function of a monitor is, of course, to serve as the visual display to help you navigate your computer. Playing Video Games
- Newer monitors are now built with high-definition imaging. Almost all of these monitors are LCD or plasma screen. Secondary Television Screen
- Because of the high technical and visual demands of computer gaming, many monitor manufacturers now sell gaming-specific monitors. These are designed to keep up with the frantic action of most computer games. Touch-Screen
- Many new high-definition televisions come with basic VGA (Video Graphics Array) adapters built into them. This means that in addition to being a fully functioning high-definition monitor, it can also be used to watch television.
- Touch-screen computers are beginning to see a resurgence in popularity, due in no small part to the monitor. Touch-screen monitors allow users to do away with the keyboard and mouse and interact with every object on the screen directly.
