Is the Nyquist theorem true for optical fiber or only for copper wire? How many end office codes were there pre-1984, when each end office was named by its three-digit area code and the first three digits of the local number? Area codes started with a digit in the range 2-9, had a 0 or 1 as the second digit, and ended with any digit. The first two digits of a local number were always in the range 2-9. The third digit could be any digit. What is the percent overhead on a T1 carrier; that is what percent of the 1.544 Mbps are not delivered to the end user? What is the difference between message switching network and packet switching? Sometimes when a mobile user crosses the boundary from one cell to another the current call is abruptly terminated even though all transmitters and receivers are functioning perfectly Why? A CDMA receiver gets the following chips: (+1 +1 +1 +1 +3 -1 -1 +3). Assuming the chip sequences for four stations as defined below, which stations transmitted, and which bit did each one send?

Please help with the following problem. The sort method, when applied to an array of strings, returns a copy of that array in which the strings appear in alphabetical order. For example, if the variable words stored the array ["foo", "bar", "biz"], then the call words .sort() would return ["bar", "biz", "foo"]. Create a

1) find the kth largest value in an unsorted array of N elements. Estimate the running time. It should be better than quick sort running time. I think O(n + klogn) is an efficient running time (if you can do a better algo, please do so). I don't need the entire program. Just functions that show the timing. This is how I did it.

What are the differences between random hashed files and index files? Compare and contrast both these non-sequential file structure models.
Compare the two non-sequential file structure models: the random (hashed) file and the index file. What advantages does the first one have over the second and what advantages does the second have over the first? What would be your criteria for choosing one over the other for different applications?
There are other design patterns that may be directly applicable to PHP programming, or web programming in general. Find another design pattern which could be used for web based development and write a synopsis on it, pointing out whether it would be applicable for use within a project that handles an upload and download function
Please show me the detailed solutions - see the attached file, thank you. a) Prove the following property for Minimum Spanning Trees: Suppose we are given a graph G with distinct edge weights. Suppose further that G has a cycle C and let c be the maximum weight edge belonging to C. Then c does not belong to any MST. b) Su

Compression algorithms are frequently used in forensics. Assume you are involved in a case and have been asked by the lawyer to explain, in general terms what they are and how they could potentially affect evidence, paying particular attention to algorithms implemented by forensic tools. You need to be clear yet concise.
Here's what Access says about searching for wildcards: When using wildcard characters to search for other wildcard characters such as an asterisk (*), question mark (?), number sign (#), opening bracket ([), or hyphen (-), you must enclose the item you're searching for in brackets.
