A group of two or more computer systems and their mutual relations. There are many types of computer networks, including:
Local area network (LAN): PC geographically close together (that is, in the same building).
And wide area networks (WAN): PC away from each other and connected by telephone lines or radio waves.
Campus area networks (boxes): computers within a limited geographical area, such as a campus or military base.
Metropolitan Area Networks MANS): data network designed for the city.
Home area networks (Hans): network within the house of a person to link users of digital devices.
In addition to these species, the following attributes are also used for the classification of the different types of networks:
Topology: geometric layout of the computer system. Mixed topologies include bus, star, and the ring. See charts and network quick reference section of Webopedia.
Protocol: Protocol defines a common set of rules and signals that computers use the network. One of the most popular protocols called Ethernet LAN. Another popular protocol LAN PC is the IBM token cordoned off the network.
Structure: networks can be regarded as using a peer or client / server structure.
PCs on the network is sometimes the contract. The computers and devices that funds for the network called servers.

What is Networking?
What is Internet?
What is Internet?
Internet, sometimes just a "net", is a global system of computer networks - a network of networks that enable users at any one computer, if they have permission to get information from another computer (and sometimes speak directly to the computers of other users) . It was developed by the Advanced Research Projects Agency (ARPA) from the Government of the United States in 1969 and was first known as the Arpanet. The original objective of establishing a network that would allow users of computers in university research to be able to "talk" computer search of other universities. One aspect of the benefit is that the Arpanet project, that the letters could be ravaged or roads in more than one direction, can reach the network to continue operating even if parts of it were destroyed in the event of a military attack or other disasters.
Internet today is an open, cooperative and self-sufficiency facility access to hundreds of millions of people all over the world. Physically, the Internet and used part of the total resources of the existing public telecommunications networks. Technically, what is the use of the Internet to a set of protocols called TCP / IP (for TCP / IP). Two recent amendments of Internet technology, Intranet and Extranet, and also take advantage of the TCP / IP protocol.
For many Internet users, electronic mail (e-mail) practically Postal Service for short transactions in writing. E-mail application is the most widely used on the Internet. You can continue to live 'talks' with other computer users, using a carry-over Internet chat (Center). Recently, the Internet telephone equipment and software allows real-time voice of the talks.
The most widely used part of the Internet is the World Wide Web (often abbreviated reflect "WWW" or "Internet"). Outstanding feature is hypertext, a way of immediate cross-referencing. In most locations, and some words or phrases in the text of a different color from other countries, and often emphasized the text. If you have any of these words or phrases, will be relocated to the site or page that is relevant to that word or phrase. Sometimes there are buttons, images or parts of images, "click". If you move the pointer over a spot on a Web site and the index changes on the one hand, this means you can click and transfer to another site.
Using the Internet, you will have access to millions of pages of information. Are surfing the Internet with a Web browser, including the most popular Microsoft Internet Explorer and Netscape Navigator. The emergence of a particular location can vary slightly as the browser you are using. Even in later versions of the browser capable of the most special of the "bells and whistles" such as animation, virtual reality, voice and music files from previous versions.

What is Word?
What is Word?
Using the computer to create, edit and print documents. Of all computer applications, word is the most common. To perform word processing, necessary for the computer, a special program called a word processor, and printer. The word processor you can find a document of the documents, electronically stored on the hard disk, and presented on the screen, by means of an amendment orders and personalities of the keyboard and print to the printer.
The great advantage of word processing using more than a typewriter is that you can change without re-printing the entire document. If you have a mistake, you just support the indicator and correct your mistake. Do you want the paragraph, you simply remove it, without leaving any trace. It is equally easy to add the word, sentence or paragraph in the middle of a document. Word processors also make it easy to move sections of the text from one place to another within a document, or between documents. When you've made all the changes you want, you can file to the printer for the paper.
Word processors vary, but each word processors support the following basic features:
Add the text: You can include text somewhere in the document.
Deleted text: Allows you to delete characters, and the words, lines, or pages that you can easily cross them on a sheet of paper.
Cut and paste: Allows you to remove the (spare) part of the text from one place in a document of the add (paste) elsewhere.
Version: Allows you to duplicate part of the text.
Page size and margins: Allows you to determine the different dimensions and margins of the page and automatically adjust the word of the text so that it fits.
And replacing the search: Allows you to direct the word processor to search for specific word or phrase. You can also direct a word to replace a set with the last letter of each place that the first group is shown.
Final word: the word to the next when you have a line filled with a single text, and that changing the text if you margins.
Print: Allows you to a document to a printer for the newspaper.
Word processors that support these features alone (and maybe a few others) and called text editors. Most word processors, but additional support function that allows you to manipulate and format of documents in more sophisticated ways. These more advanced word processor sometimes very complete word processors. Fully equipped word processors generally support the following characteristics:
File management: many, the word processor file administrative capacity that enables you to delete, transfer, searching for files.
Line Features: Allows you to the lines within a document. For example, you can bold, italic and underlined. Most word processors also allow you to set the font size on the line.
Notes and references: automatic numbering and footnotes, and you can easily cross-reference other sections of the document.
Graphics Graphics: You can also photos and graphics in a document. Some word can change the setting of illustrations in a word processor lets you another example produced by different programs.
Capital, margins and pagination: Allows you to determine the capital-conditioning and margins that the word processor will be at the top and bottom of each page. Word processor automatically tracking page numbers, so that the correct number appears on each page.
Design: Allows you to define different margins within a single document and identifying different methods of indenting paragraphs.
Macro: the holistic nature of the word, which is a series of strikes the keys. The text can be a major strikes or orders. The possibility of macros you can do a lot of time by replacing the common set of keys strikes.
Integrates: Allows you to integrate text, a file to another file. This is especially useful for many of the files that have the same format but different data. Generation of e-cards is a classic example of the use of integrated.
Clarify Examiner: tool that you can check the spelling of words. It will highlight all the words that they do not recognize.
Table of Contents and indexes: Allows you to automatically create table of contents and an index of blogs on the basis that you add in this document.

On the other hand, investing in expertise and marketing must be consistent and raise the level of services in the face of competition that would also be little physical limitations.
What is Software?
Software is a generic term for the various types of software used for computers and related equipment. (The term describes the equipment and material aspects of computers and related devices.)
Software can be seen as part of the change of hardware and constants part. Software is often divided into application software (programs that do the work directly to the user) and system software (including operating systems and any program, supported by application software). Intermediate term is sometimes used to describe the programming that mediates between application and system software or between two different types of application software (for example, sends a request to work after the application of computers in which one type of operating system called for in other computer operating system ).

And the difficulty of additional classification category of software is useful, is a useful little program with a limited capacity. Some tools come with operating systems. As applications, utilities, tend to stabilize and the unit can be used independently of the rest of the operating system.
Applications are small applications that sometimes comes with the operating system "accessories". They can also be created using a separate Java or other programming languages.

Software can be purchased or obtained, as my computer can be copied and distributed (usually destined for sale after the trial period), lite ware (Shareware copied and distributed with a number of opportunities for persons with disabilities), and free (free software , But with copyright restrictions), and public domain software (free with any restrictions), and open source (software whose source code is furnished and users do not agree to limit the distribution of improvements).
Software is often coated on CD-ROMs and diskettes. Today is a big part of the purchase of software, my computer can be copied and distributed, a free download on the Internet. A new trend is the software available for use at another location known to provide services applications.
What is SAP?
