Worst case of Quicksort algorithm?

The worst case occurs when data is already sorted where the complexity is O(n^2) instead of the well known O(n log n)

What is relational in relational model?

A Relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as introduced by E. F. Codd. Most popular commercial and open source databases currently in use are based on the relational model. A short definition of an RDBMS may be a DBMS in which data is stored in the form of tables and the relationship among the data is also stored in the form of tables.

What is a stock sorting algorithm?

Stock sorting algorithm is a algorithm which is used to sort any kind of stock i.e. any data type containing the primitive values like array ,link list ,stack etc.

What is the main function of an IP address?

Provide a unique logical address for each device on the network. Each networked device has a globally unique physical address, commonly referred to as the MAC-ID.

While the MAC-ID is guaranteed to be globally unique, it refers to a particular hardware, not to a particular device. For example, your PC's Ethernet MAC-ID will change when the LAN card changes, but its logical address (the IP address) may not have to change at the same time. This allows other devices to continue communicating with your PC even after its MAC-ID changed.

IP addresses are also grouped into subnets, which supports routing. It messages were sent using MAC-ID (physical) addressing, the message must be repeated into every subnet because the destination device could be anywhere.

What is shlibsign?

It is a program that has something to do with Mozilla. I got a warning from KDE that it was slowing down my system.

Describe the process of segmentation and reassembly?

Segmentation and

Reassembly refers to the

process used to fragment

and reassemble variable

length packets into fixed

length cells so as to allow

them to be transported

across Asynchronous

Transfer Mode (ATM) networks

or other cell based

infrastructures.

Since ATM's payload is only 48

bytes, nearly every packet

from any other protocol

has to be processed in

this way. Thus, it is an

essential process for any

ATM node. It is usually

handled by a dedicated

chip, called the SAR.

Why does a multiplication algorithm work the way it does?

The answer to this question depends on the multiplication algorithm you are working with. If you are working with an algorithm for multiplying fractions, the answer of why it works the way it does is going to be different than if you are multiplying whole numbers. If you are looking to explain multiplication algorithms to young children (and even to explain algorithms to older children or to better understand them yourself), it is useful to use physical objects and play with multiplication. Once you work out a few of the type of problem you are doing (or a scaled down version if you are working with large numbers) it will likely become clearer to you why it works the way it does.

What is the difference between pure and impure function in computer language?

A pure function is one function that has no side effects or output and doesn't depend on any state beyond its local state's means it can be replaced by any other pure function which returns same result given the same inputs.This property is often referred as referential transparency

Is java an assembly language?

No. Java is a high level language also known as object oriented programming

Applications of device driver?

There is only one application for a device driver: to allow the operating system to interact with a specific piece of hardware.

What is objective in language arts?

I don't know if this is what you are asking, but I'll give it a try.

There are certain forms of 'terms' for use of a better word, in language arts.

Objective is a 'term'. There are two types of objects-Direct and Indirect.

Here are a couple of examples:

He likes his job. He likes what? He likes job. Job is the Direct Object in the sentence.

Jamaica bakes John a cake. Jamaica bakes what? Jamaica bakes cake. Cake is the Direct Object. (DO) In this case, there is an indirect object (IO) also. Jamaica bakes cake to whom? To John. John is the Indirect Object of the sentence.

Hampton needs his pencil case. Hampton needs what? Hampton needs case. Case is the DO. Pencil is an adjective modifying case.

Be careful of Predicate Nominatives and Predicate Adjectives. Examples:

Alex is a carpenter. Alex is what? Alex is carpenter. But, wait a moment: Alex is the carpenter--Carpenter is Alex. Carpenter is the Pred. Nominative.

Holly's fingers were quick on writing the essay. Quick is a Pred. Adjective. Quick fingers. Quick modifies the subject, fingers.

I don't know if this was what you wanted, but anyway, hopefully you got smarter! (in any case) So, again, hope this helped/helps!

Is Programming a language?

No, but of course there is a programmers' slang.

And programming is done with so-called 'programming languages'.

In code what property of a radio button shoud you test to determine whether it is selected?

Radio buttons need to be placed in the appropriate type of frame. A radio button's value is always static, however the frame that you bind the radio button to will have the value of the selected radio button.

When will you use polynomial expressions in the work area?

Lots of places. In engineering, anything that involves approximating behaviors using Taylor expansions, for example. In business, compound interest and rate of return calculations are two areas that require knowledge of polynomials. I assume you are asking this because you are studying them in school and are having trouble seeing why they are relevant. In part, the study of algebra teaches you to think in certain analytical ways that become very valuable even if you don't use all of the specific techniques you've learned. After all, no one pays to hear a musician practice scales, but the skills they learn in doing that practice are part of the foundation for their actual performance. And if you do end up in a business that requires a lot of math, as I did, those skills - and a lot more - come up all the time. So yeah, math matters!

How can you start the program 'read in the lengths of the sides of a triangle and determine whether the triangle is an isosceles triangle two sides are equal an equilateral triangle three sides are'?

This would depend on what programming language you wanted to write it in. For example, in Pascal, the code might look like this:

Program Isosceles;

Var

A, B, C : Real;

Begin

WriteLn('Input side A.');

ReadLn(A);

WriteLn('Input side B.');

ReadLn(B);

WriteLn('Input side C.');

ReadLn(C);

If A = B Then

Begin

If B = C Then

Begin

WriteLn('This triangle is equilateral.');

End

Else

Begin

WriteLn('This triangle is isosceles.');

And so on.
