hi there,,,,,,!!! I am ajit yadav please see my ms powerpoint presentation 2007 & comment my ppt 'Microsoft Office 2007 (codenamed Office 12)[4] is a version of Microsoft Office, a family of office suites and productivity software for Windows, developed and published by Microsoft. It was released to volume license customers on November 30, 2006[5] and to retail customers on January 30, 2007, the same respective release dates of Windows Vista. It was preceded by Office 2003 and succeeded by Office 2010. Office 2007 introduced a new graphical user interface called the Fluent User Interface, which uses ribbons and an office start menu instead of menu bars and toolbars.[6] Office 2007 requires at Windows XP with Service Pack 2, Windows Server 2003 with Service Pack 1, or a later OS.[2] Office 2007 is the last version of Microsoft Office to support Windows XP Professional x64 Edition. Office 2007 includes new applications and server-side tools, including Microsoft Groove, a collaboration and communication suite for smaller businesses, which was originally developed by Groove Networks before being acquired by Microsoft in 2005. Also included is Office SharePoint Server 2007, a major revision to the server platform for Office applications, which supports Excel Services, a client-server architecture for supporting Excel workbooks that are shared in real time between multiple machines, and are also viewable and editable through a web page. With Microsoft FrontPage discontinued, Microsoft SharePoint Designer, which is aimed towards development of SharePoint portals, becomes part of the Office 2007 family. Its designer-oriented counterpart, Microsoft Expression Web, is targeted for general web development. However, neither application has been included in Office 2007 software suites.123

2. Computer
• A computer is an electronic device that accepts, stores and
output data high speeds.
Monitor
CD Rom Drive

3. Basic operations of a computer
• A computer is nothings but a combination of several non living physical components . Whenever all those
physical components (called hardware) in combination give an output than it is a computer . Let us take a
look of the above picture of a computer. It is consists of a several Hardware components like keyboard,
mouse, speaker, monitor, CPU, Hard disk, Floppy, CD Rom etc. and the functions of all these parts are
quite different. If you analyze all the physical parts of a computer you will be notice some devices are for
inputting data, some for storing data, some are for processing and some for outputting. Naturally whatever
is your computer system consists of; they just perform the following four basic operations.
• Inputting:- The processes of entering data and instructions into the computer system. Inputting is done
by the Input Devices. Example of some input Devices are:- keyboard, mouse, sound card ,video capture
card, Digital camera , Joystick, Light and pen etc.
• Storing:- Saving data and instructions so that they are available for initial or for additional processing
as when required is known as storing. Computer store all data in to its memory. We will discuss computer
memory in details in later section.

4. Processing
• Performing arithmetic operations or logical operations
(comparisons like equal to less than, grater than etc.) on data in
order to convert them into useful information. Processing is done
by the computer processor. Some processor names are Pentium
III, Pentium IV etc.
• OUTPUTING:- The process of producing useful and processed
information or result for the user, such as a printed report or visual
display. For outputting computer uses several output devices like monitor,
printer, speaker.
• INPUT DEVICES:- Input devices are used to put data and
instructions into the computer. There are many different types of input
devices and here are some of them.

5. KEYBOARD
• Keyboard:- keyboard is found on computers like desktops and note
books. Its layout is very similar to a type writer. It is use for a wide range of
tasks. It is use for typing in data from paper documents such as
applications forms which people have filled in. it is also used for entering
different types of data.

6. MOUSE
• MOUSE:-A mouse is a pointing input device that work upon GUI(Graphic
user interface)platform. Whenever you move mouse arrow pointer also moves
according to the direction you are moving .this pointer is used to perform different tasks
associated with the mouse.

7. TOUCH PAD
• TOUCH PAD:-This device is use on laptop computers . Instead of
moving a mouse , you control the movement an object on the screen the pad. The
pointer moves across the screen in the direction you move your finger . If you tab the
touch pad this has the same effect as clicking the mouse. There are also buttons on a
mouse.

8. JOYSTICK

9. Digital Camera

10. SCANNER
• SCANNER:- A scanner is used to make a copy of what is on paper
and store it in the computer. It does not mater what is on the paper, whether
it is a picture, text even bar codes. An example is the use of a scanner to copy
photographs into desk top publishing software as part a different magazine.

11. STORING DEVICES
The data and instructions that are entered into the computer system through input
units have to be stored inside the computer before the actual processing starts. For
storing computer uses its memory. Computer memory divided in to two parts.
(A)Primary or main memory
(B) Secondary or Backing storage
(A) PRIMARY OR MAIN MEMORY:-Main memory of a computer is a general term for any type
of computer memory other than backing storage(secondary storage devise).

12. (B)Secondary or Backing storage
• Secondary Memory:- Secondary memory is used as permanent
storage for programs and data in a computer system . Backing storage is also called
secondary storage or mass storage.
Main memory consists of a (RAM)Random Access Memory AND (ROM) Read Only Memory

13. • Random access memory is a type of computer memory which holds its data as long as the computer is switched on.
When the computer is switch off, any data held in RAM is lost. RAM is volatile memory.
•Read only memory is a type of computer that hold permanently . Data held in ROM can be
read by the CPU in any order.ROM is there for another type of direct access medium.

14. • Computers use the binary system because it is easy to represent the two states “on”
and “off” inside a computer.
4 Bits= 1 Nibble
8 Bits= 1 Bytes
1024 bytes= 1 Kilobyte (KB)
1024 KBs= 1 Megabyte (MB)
1024 MBs= 1 Gigabyte(GB)
1024 GBs=1 Tera Byte (TB)

15. HARD DISKS
• A hard disk(commonly know as a HDD(hared disk drive)or(HD) and
formerly known as a fixed disk)is a nonvolatile storage devise which store
digitally encoded data on rapidly rotating platters with magnetic surfaces.
• OPTICAL:- Optical storage media includes CD-ROM (compact disk –
Read only memory) CD-R(compact Disk Recordable),CD-RW(compact Disk
Re writable),Together with DVD-ROM(Digital Versatile Disk),DVD-Vide o,
DVD Audio, DVD-R(Digital versatile Disk Recordable)and DVD-RAM.

16. CENTRAL PROCESSING UNIT (CPU)
• The CPU is the brain of a computer and consists of 3 main parts: the control unit the arithmetic and logic unit
(ALU) and the main memory .
• CENTRAL PROCESSING UNIT (CPU)
Control unit coordinates the
whole operation of the computer.
It fetches instruction from main
memory, processes them and
executes the necessary action
Arithmetic and logic unit
Performs the Arithmetic and the
logical operations such as AND and
OR
Main memory Contains data and
instrucations.Also know as the
immediate access store
for primary store
Processor
Since there are no moving parts, the processor Perform its functions at
incredibly high speeds.
