• 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????? just 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.

What is The Spreadsheet ??

• The spreadsheet has changed the way people do
  business.
• 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 speculation.

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 hand.
11
PowerPoint
PowerPoint is a complete presentation graphics
package. It gives you everything you need to
produce a professional-looking presentation.
PowerPoint offers word processing, outlining,
drawing, graphing, and presentation management
tools- all designed to be easy to use and learn.

Network and Internet Basics

• PC Network Basics
• The internet is an elaborate network of
  interconnected networks ?????a 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 .

13
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 system.

14
The Internet Explosion

• Some examples about Internet Explosion
• Electronic mail
• E-mail software made it easy to send messages
  across the office or around the world
• World Wide Web
• Led the Internets transformation from a
  text-only environment into a multimedia landscape
  incorporating pictures, animation, sounds, and
  video
• people connect to the web each day through Web
  browsers
• Programs that, in effect, serve as navigable
  windows into the Web

15
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
  brains
• robotics programming computers to see and hear
  and react to other sensory stimuli

16
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

17
database
To access information from a database, you need
a database management system (DBMS). This is a
collection of programs that enables you to
enter, organize, and select data in a database.
(2) Increasingly, the term database is used
as shorthand for database management system.

• 1) Often abbreviated DB. A collection of
  information organized in such a way that a
  computer program can quickly select desired
  pieces of data. You can think of a database as an
  electronic filing system.
• 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.
• 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.

19
some the common terminology

• Image Effects
• Many graphics programs come with predefined
  algorithms that enable you to add special effects
  to your images. The actual effects will depend on
  the software you use. However, there are some
  standard ones that you can expect to find in a
  good program

2. Color DepthIn computer graphics, color depth
is how you describe the range of colors that can
be used in an image. The more colors used in an
image, the more realistic it will look 3.
EraserEraser tools allow you to erase areas
within your image to leave behind transparency or
a background color. There is also a Background
Eraser which provides more control in removing a
background to transparent
