Android Architecture Google entered the mobile phone market in a style that only multibillion-dollar companies can afford: it bought a company. In 2005, Google, Inc. purchased Android, Inc. At the time, Android was relatively unknown, despite having four very successful people as its creators. Founded by Andy Rubin, Rich Miner, Chris White, and Nick Sears in 2003, Android flew under the radar, developing an operating system for mobile phones. With a quest to develop a smarter mobile phone that was more aware of its owner’s preferences, the team behind the Android operating system toiled away in secrecy. Admitting only that they were developing software for mobile phones, the team remained quiet about the true nature of the Android operating system until the acquisition in 2005. With the full might of Google’s resources behind it, Android development increased at a rapid pace. By the second quarter of 2011, Android had already captured nearly a 50% market share in mobi...

What is SEO?  SEO is the process of improving web pages so they rank high in search engines for   a   specific   keyword   phrase.   SEO   is   divided   in   two   categories:   on-page optimization   and   off-page   optimization.   On-page   optimization   it   refers   to   every method   you   use   that   change   the   page   code;   off-page   optimization   equals   link popularity (more on this later) Choosing the right keywords  The center of optimization are the keyword phrase(s) for which you want a high ranking in search engines result pages (SERP’s). When you choose you keyword phrase  you  must take in consideration primarily your  market (they must reflect what   you   sell)   ,   the   number   of   searches   for   it   and ...

C # is similar to Java in terms of syntax; it is an object-oriented language from Microsoft that started around 1997. C# also known as C sharp is available to run on multiple platforms, such as Windows, UNIX, Linux and Solaris. C# uses the Microsoft .NET framework and the Mono framework to be interpreted and translated into a language that is capable of running fast on any computer. C sharp is the third most popular language to be use with these frameworks and it is the most popular .NET language used today by .NET programmers. Anders Hejlsberg was the lead architect and principal designer of C#, he was involved with the design of Turbo Pascal, Embarcadero Delphi and Visual J++ before the creation of C sharp. The design of C# was driven by flaws in most major programming languages such as C++, Java, Delphi and Smalltalk, according to Anders Hejlsberg. C# however, was called an imitation of Java, by James Gosling, the creator of Java programming language and the co-founder of ...

 Java, having been developed in 1991, is a relatively new programming language.   At that time, James Gosling from Sun Micro systems and his team began designing the first version of Java aimed at programming home appliances which are controlled by a wide variety of computer processors.      Gosling's new language needed to be accessible by a variety of computer processors.  In 1994, he realized that such a language would be ideal for use with web browsers and Java's connection to the internet began.  In 1995, Netscape Incorporated released its latest version of the Netscape browser which was capable of running Java programs. Www.ITExpertTeam.Blogspo.Com Why is it called Java?  It is customary for the creator of a programming language to name the language anything he/she chooses.  The original name of this language was Oak, until it was discovered that a programming language already existed that was named Oak.  As t...

In the early 1970s, Dennis Ritchie of Bell Laboratories was engaged in a project to develop a new operating system.  Ritchie discovered that in order to accomplish his task he needed the use of a programming language that was concise and that produced compact and speedy programs. This need led Ritchie to develop the programming language called C. a      In the early 1980's, also at Bell Laboratories, another programming language was created which was based upon the C language.  This new language was developed by Bjarne Stroustrup and was called C++.  Stroustrup states that the purpose of C++ is to make writing good programs easier and more pleasant for the individual programmer.  When he designed C++, he added OOP (Object Oriented Programming) features to C without significantly changing the C component.  Thus C++ is a "relative" (called a superset) of C, meaning that any valid C program is also a valid C++ program.

A network is a group of two or more computer systems linked together. There are many types of computer networks, including: local-area networks (LANs) : The computers are geographically close together (that is, in the same building). wide-area networks (WANs) : The computers are farther apart and are connected by telephone lines or radio waves. campus-area networks (CANs): The computers are within a limited geographic area, such as a campus or military base. metropolitan-area networks MANs): A data network designed for a town or city. home-area networks (HANs): A network contained within a user's home that connects a person's digital devices. computer network diagram In addition to these types, the following characteristics are also used to categorize different types of networks: Www.ITExpertTeam.Blogspo.Com topology : The geometric arrangement of a computer system. Common topologies include a bus, star, and ring. See the Network topology diagrams in the Quick Re...

Difference between CUI and GUI? • CUI and GUI are user interface used in connection with computers • CUI is the precursor of GUI and stands for character user interface where user has to type on keyboard to proceed. On the other hand GUI stands for Graphical User Interface which makes it possible to use a mouse instead of keyboard • GUI is much easier to navigate than CUI • There is only text in case of CUI whereas there are graphics and other visual clues in case of  GUI • Most modern computers use GUI and not CUI • DOS is an example of CUI whereas Windows is an example of GUI.

ACCOUNTING EQUATION For every business enterprise, the sum of the rights to the properties is equal to the sum of the properties owned.  The properties owned by a business are called assets.  The rights to the properties are called equities. Assets and equities are the basic elements of accounting.  We can express these elements by an equation known as “Accounting Equation”. Assets = Equities Or Assets = Liabilities + Owner Equity. CASH BOOK A book in which we record all the transactions relating to cash is called cashbook.  Cash received from sales of goods, services or from any other source is recorded on the debit side of the cash book while payments made for the goods / assets purchased and expenses are recorded on the credit side. Generally there are three kinds of cashbook. ·          Simple Cash Book / One Column Cash Book ·          Cash Book With Discoun...

 Study Guide Demo The following topics are covered in this chapter: 1 1 Understanding the Functions of Networking ■ ■ What Is a Network? ■ ■ Common Physical Components of a Network ■ ■ Interpreting a Network Diagram ■ ■ Resource-Sharing Functions and Benefits ■ ■ Network User Applications ■ ■ Impact of User Applications on the Network ■ ■ Characteristics of a Network ■ ■ Physical Topologies ■ ■ Connection to the InternetYou’d have to work pretty hard these days to find someone who would argue that our computers have not become invaluable to us personally and professionally. Our society has become highly dependent on these resources and on sharing them. The ability to communicate with those we need to—whether they’re in the same building or in some faraway land—completely hinges on our capacity to create and maintain solid, dependable networks. And those vitally important networks come in all shapes and sizes—ranging from small and simple to humongous and ...

Books Demo  C Language Overview This chapter describes the basic details about C programming language, how it emerged, what are strengths of C and why we should use C. T he C programming language is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972. In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard. The UNIX operating system, the C compiler, and essentially all UNIX applications programs have been written in C. The C has now become a widely used professional language for various reasons.  Easy to learn  Structured language  It produces efficient programs.  It can handle low-level activities.  It can be compiled on a variety of computer platforms.
