What is validation of an algorithm?
Once an algorithm has been devised it become necessary to show that it works it computer the correct to all possible, legal input. One simply way is to code into a program. However converting the algorithm into program is a time consuming process. Hence,it is essential to be reasonably sure about the effectiveness of the algorithm beforeit is coded. This process, at the algorithm level,is called"validation". Several mathematical and other empirical method of validation are available. Providing the validation of an algorithm is a fairly complex process and most often a complete theoritical validation though desirable, mey not be provided. Alternately, algorithm segment,which have been proved elsewhere may be used and the overall working algorithm may be empirically validated for several test cases.Such method,although suffice in most cases,may often lead to the presence of unidentified bugs or side effect later on.
And
The process of measuring the effectiveness of an algorithm before it is coded to know the algorithm is correct for every possible input.This process is called validation. Example :-
This article describes the algorithms for validating bank routing numbers and credit card numbers using the checksum built into the number. While they differ in how they are generated, the technique used for both is similar.

In computer science, a linker or link editor is a program that takes one or more objects generated by a compiler and combines them into a single executable program.
http://en.wikipedia.org/wiki/Linker
This is a response to the question, "What is object linker?". The appropriate question would have been, "What is a linker or link editor in the field of Computer Science and Software Engineering?". Note that a linker is called a loader when it refers to a run-time process. Linkers refer to compile-time processes.
The importance of the computer?
Computer training takes a computer from a common household item to a powerful tool for work, school, and personal tasks. Enrolling in a computer training program can teach you how to use common software programs and also maintain your computer's hardware. Specialized training for computers is also available to focus on a specific type of program, such as word processing, or a specific type of task, such as managing finances.
What tag will make words FLASH on and off repeatedly?
You can use the <blink> tag, but the best you can do is do this: <span id="blah">Some Text here</span> and put this code in a script tag:
function go() {
if (document.getElementById("blah").style.visibility == "visible") {
document.getElementById("blah").style.visibility = "hidden";
}
else {
document.getElementById("blah").style.visibility = "visible";
}
}
window.onload = function() {var x = window.setInterval("go()", 200);};
Change blah to whatever you need it to be, and the document.getElementBy("blah") to the id attribute. change 200 to how fast it blinks in milliseconds
The BTB stands for:
Bromothymol Blue
Mostly used for testing the water if there is acid or not.
Difference between super and mini computer?
The difference between a super computer and a mini computer is in their computing power. A super computer has infinitely more computing power than a mini computer.

What does restricted access major mean?
It means you must meet the requirements for entrance to the major. Its not open to all students but only those who qualify. You will usually find this in the health related majors.

What are the disadvantages of low level language?
There are several disadvantages in low level programming languages
I guess it would be the LSB, the bit that represent value 20=1
What is the Difference between coarse grained and fine grained parallelism?
Granularity refers to the ratio of actual computation to the amount of communication required by a parallel system.
A fine-grained system will do a small amount of computation before transferring data/results. A coarse-grained system will do a relatively large amount of computation before reporting back.
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.
How many bits would be needed to represent a 45 character set?
45 in binary is 101101, so you need at least 6 bits to represent 45 characters.
