Time Complexity Factor Big O of Sorting Algorithms

Sorting algorithms used in computer science are often classified by:

Computational complexity (worst, average and best behaviour) of element comparisons in terms of the size of the list (n). For typical sorting algorithms good behavior is O(nlogn) and bad behavior is .  Ideal behavior for a sort is , but this is not possible in the average case.Comparison-based sorting algorithms, which evaluate the elements of the list via an abstract key comparison operation, need at least comparisons for most inputs.
Computational complexity of swaps (for "in place" algorithms).

Memory usage (and use of other computer resources). In particular, some sorting algorithms are "in place". This means that they need only or memory beyond the items being sorted and they don't need to create auxiliary locations for data to be temporarily stored, as in other sorting algorithms.

Recursion. Some algorithms are either recursive or non-recursive, while others may be both (e.g., merge sort).

Stability: stable sorting algorithms maintain the relative order of records with equal keys (i.e., values). See below for more information.

Whether or not they are a comparison sort. A comparison sort examines the data only by comparing two elements with a comparison operator.

General method: insertion, exchange, selection, merging, etc.. Exchange sorts include bubble sort and quicksort. Selection sorts include shaker sort and heapsort.

Adaptability: Whether or not the pre sortedness of the input affects the running time. Algorithms that take this into account are known to be adaptive.

Mobile Operating systems

A mobile operating system, is a a mobile platform, or a handheld operating system, is the operating system that controls a mobile device or information appliance—similar in principle to an operating system such as Windows, Mac OS X, or Linux that controls a desktop computer or laptop. However, they are currently somewhat simpler, and deal more with the wireless versions of broadband and local connectivity, mobile multimedia formats, and different input methods.


Android
Android is a mobile operating system for mobile devices such as mobile phones and tablet computers developed by the Open Handset Alliance led by Google.Android consists of a kernel based on the Linux kernel, with middleware, libraries and APIs written in C and application software running on an application framework which includes Java-compatible libraries based on Apache Harmony.Android uses the Dalvik virtual machine withjust-in-time compilation to run compiled Java code. ( Source :wikipedia )

Some other mobile operating systems are Symbian , iOS , BlackBerry OS , Windows CE etc.

Terms associated with Web Technology

What is a favicon ?
Favicons : Favourites icons are tiny logos that appear at the far left of a browser’s address bar. They can be static or animated, depending on your browser, and give websites that use them a little extra personality.

What is https?
Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext TransferProtocol (HTTP) with SSL/TLS protocol.

What is LYNX?
Lynx is one of the most popular web browsers for command-line interfaces.

What is SEO?
SEO: Search Engine Optimization is a technique which helps search engines find and rank your site higher than the millions of other sites in response to a search query.

What is captcha?
A CAPTCHA or Captcha is a type of challenge-response test used in computing to ensure that the response is not generated by a computer.

What is Trap Door?
Trap doors, also referred to as backdoors, are bits of code embedded in programs by the programmer(s) to quickly gain access at a later time, often during the testing or debugging phase. If an unscrupulous programmer purposely leaves this code in or simply forgets to remove it, a potential security hole is introduced. Hackers often plant a backdoor on previously compromised systems to gain later access. Trap doors can be almost impossible to remove in a reliable manner. Often, reformatting the system is the only sure way.

What is Deadlock in Operating System ?


Deadlocks
In a multiprogramming environment, several processes may compete for a finite no.of resources. A process requests resources, if the resources are not available at that time, the process enters a wait state. it my happen that waiting process will never again change state, because the resources have requested are held up by other waiting processes. this situation is called Deadlock.
A deadlock state occurs when two or more processes are waiting indefinitely for an event that can be caused only by one of the waiting process.
A Deadlock situation may occur if and if four necessary conditions hold simultaneously in the system. namely mutual exclusion, hold and wait, no preemption and circular wait. 

Prevention of Deadlock.
To prevent deadlock we ensure that at lease of the necessary condition (namely mutual exclusion, hold and wait, no preemption and circular wait ) never holds.

Deadlock Avoidance 
Deadlock avoidance is less stringent than the prevention algorithm is to have priori information on how each process will be utilizing the resources.

Banker’s Algorithm
It is a Deadlock avoidance algorithm . This algorithm needs to know the maximum no.of each resource class that may be requested by each process.

Q. What is a System software ?
System software is computer software designed to operate the computer hardware and to provide a platform for running application software. eg: Operating System


Q. What is an assembler ?
Assembler converts each assembly language statement into the corresponding machine-language statement.
There are two types of assemblers.
One-pass assemblers go through the source code once and assume that all symbols will be defined before any instruction that references them.

Two-pass assemblers create a table with all symbols and their values in the first pass, then use the table in a second pass to generate code.



Q.What are various steps to design an assembler?

1. Statement of problem:

2. Data structure:

3. Format of data bases:

Here we specify the format and content of each of the data bases task that must be undertaken even before describing the specific algorithm underlying the assembly design.

4 Algorithm: There are two passes in this


Q.Define Lexical Analysis
lexical analysis is the process of converting a sequence of characters into a sequence of tokens. A program or function which performs lexical analysis is called a lexical analyzer.


Q.What is YACC ?
YAAC is a computer program used as a parser generator developed by Stephen C. Johnson at AT&T for the Unix operating system. The name is an acronym for "Yet Another Compiler Compiler." It generates a parser (the part of a compiler that tries to make syntactic sense of the source code) based on an analytic grammar written in a notation similar to BNF.
