                 Word Processing

 You can use a word processing program, such as
 Microsoft Word, to create memos, letters, term papers, novels,
textbooks, or Word Wide Web page ‫ـــــ‬just about any kind of
text-based document.

 In the PC world, a document is a file created by an application.

 You can type and edit a word processing document using standard
PC techniques and tools.
  Word processing program, contain text editing tools for changing
and rearranging the words on the screen.
  Most computer users are familiar with the Clipboard, which can
temporarily store chunks of text and other data, making it possible to
cut or copy words from one part of a document and paste them into
another part of the same document or a different document.
  Text formatting commands enable you to control the format of the
document .for Example, you can change the way the words will look
on the page. Most modern word processors include commands for
controlling the formats of individual characters and paragraphs as well
as complete document.

  What is desktop publishing?
The process of producing a book, magazine, or other
  publication includes several steps:
  Writing text.
  Editing text.
  Producing drawing, photographs, and other graphics to
  accompany the text.
  Designing a basic format for the publication.
  Typesetting text.
  Arranging text and graphics on pages.
  Typesetting and printing pages.
  Binding pages into a finished publication.

With Desktop-Publishing (DTP) technology, the bulk of
  the production process can be accomplished with
  tools that are small, affordable, and easy to use.

 Why Desktop Publishing?
                  Desktop publishing
                  offers several
                  advantages for
                  Desktop publishing
                  saves money also
                  saves time.
                  Finally, desktop
                  publishing can reduce
                  the quantity of
                  publication errors.

 What is The Spreadsheet ??
The spreadsheet has changed the way people do
Spreadsheet software enables the user to take
control of number, manipulating them in ways
that would be difficult or impossible otherwise.
A Spreadsheet program can make short work of
tasks that involve repetitive calculations:
budgeting, investment management, business
projections, grade books, scientific simulations,
checkbooks, and so on.
A spreadsheet can also reveal hidden
relationships between numbers, taking much of
the guesswork of financial planning and

        You can creating worksheet with           Microsoft Excel
    Microsoft Excel is a spreadsheet program that lets you organize
 your data into lists and then summarize, compare, and present your
data graphically. For example,you can have Excel find the sum,
average, or maximum value for sales on a given day; creat graph
showing what percentage of sales were in particular range; and
show how the total sales compared with the total sales of other days
in the same week.
 In short, Excel saves you from having to create these summaries by

         Network and Internet Basics
PC Network Basics:
The internet is an elaborate network of
  interconnected networks ‫ـــــ‬a network that
  is dramatically change the way people
  work, play, and communicate.
Internet Basics:
 A PC can be a window into the global
  system of interconnected networks known
  as the internet, or just the Net .

   The Internet Revolution
The Emergence of Networks
Local-Area Networks (LANs):
computers are physically close to each
  other, usually in the same building, so
  they could share resources, such as
  storage, printers.
Wide-Area Networks (WANs) extends
  over a long distance.
     a remote computer could connect to
  a network through standard telephone
  lines by using a modem, or using
  wireless connections.
   a modem is an electronic device that
  could translate computer data into
  signals compatible with the telephone

artificial intelligence
The branch of computer science concerned with making computers
   behave like humans.

Artificial intelligence includes
games playing: programming computers to play games such as
  chess and checkers
expert systems : programming computers to make decisions in real-
  life situations (for example, some expert systems help doctors
  diagnose diseases based on symptoms)
natural language : programming computers to understand natural
  human languages
neural networks : Systems that simulate intelligence by attempting
  to reproduce the types of physical connections that occur in animal
robotics : programming computers to see and hear and react to other
  sensory stimuli

database management system
A collection of programs that enables you to
  store, modify, and extract information
  from a database. There are many
  different types of DBMSs, ranging from
  small systems that run on personal
  computers to huge systems that run on
  mainframes. The following are examples
  of database applications:
  computerized library systems
  automated teller machines
  flight reservation systems
  computerized parts inventory systems

               database management system (DBMS).
    You can think of a database as an electronic filing system.
      This is a collection of programs that enables you to enter,
               organize, and select data in a database.
   Traditional databases are organized by fields, records, and files. A field is
    a single piece of information; a record is one complete set of fields; and a
    file is a collection of records. For example, a telephone book is analogous
    to a file. It contains a list of records, each of which consists of three fields:
    name, address, and telephone number.
    (2) Increasingly, the term database is used as shorthand for
                  database management system.
   An alternative concept in database design is known as Hypertext. In a
    Hypertext database, any object, whether it be a piece of text, a picture, or a
    film, can be linked to any other object. Hypertext databases are
    particularly useful for organizing large amounts of disparate information,
    but they are not designed for numerical analysis.

Graphics Software Terminology
     Graphics jargon can be confusing, especially for
       those who are just learning how to edit digital
       photographs or work with images for printing
       or Web pages.

         There are countless graphics software
       packages available, each with its own options
       and even different names for the basic
       functions you can use to manipulate images
       (also called image enhancement).

         To help you better grasp graphics software,
       we take a look at the genre and define some
       the common terminology to help you better
       maneuver your way through the basics of
       working with your digital images.

1. Image Effects
Many graphics programs
  come with predefined
  algorithms that enable
  you to add special
  effects to your images.
  The actual effects will     Original Image         Artistic Effect: Neon Glow

   In computer graphics, color depth is
   how you describe the range of colors
   that can be used in an image. The more
