IT Quotes

"It is not sin that U did not reach at a star but it is a sin that U did not have A star to reach for"

Information technology and business are becoming inextricably interwoven. I don't think anybody can talk meaningfully about one without the talking about the other. 

Bill Gates 

The history of computer

STEPS TOWARD MODERN COMPUTING

Today’s electronic computers are recent inventions, stemming from work that

began during World War II. Yet the most basic idea of computing—the notion

of representing data in a physical object of some kind, and getting a result by

manipulating the object in some way—is very old. In fact, it may be as old as

humanity itself. Throughout the ancient world, people used devices such as

notched bones, knotted twine, and the abacus to represent data and perform

various sorts of calculations

First Steps: Calculators

During the sixteenth and seventeenth centuries, European mathematicians

Developed a series of calculators that used clockwork mechanisms and

cranks  As the ancestors of today’s electromechanical

adding machines, these devices weren’t computers in the modern sense. A

calculator is a machine that can perform arithmetic functions with numbers,

including addition, subtraction, multiplication, and division.

The Technological Edge: Electronics

Today’s computers are automatic, in that they can perform most tasks without

the need for human intervention. They require a type of technology that

was unimaginable in the nineteenth century.

Steps Toward Modern Computing: A

abacus (4000 years ago to 1975)

Used by merchants throughout the ancient world. Beads represent figures

(data); by moving the beadsaccording to rules, the user can add,subtract, multiply, or divide. The abacusre  mained in use until a worldwide deluge of cheap pocket calculators put the abacus out of work, after being used for thousands of years.

Ribbon consists of Tabs .  groups and also commands and are located at the  top  of Window 

Mini toolbar 

                   Mini toolbar purpose is to minimize  the Mouse movement  consists of command related to the changing the appreance of text  in the document 

Quick Access toolbar 

A Quick access toolbar is a customized toolbar that contain a set of commands that are independent or the tab that is currently displayed.

The operating system

Microsoft created the operating system, Windows, in the of the  mid-1980s. . 

Windows is a proprietary software, which means that Microsoft has placed restrictions on how people can use or copy the software. 

Windows comes p reloaded on most of the PCs sold today, and can also be purchased separately

The Window 7  

Windows 7 also saves time by not booting up various devices during Start Up unless they are currently being used. In other words, if you are not using a Bluetooth device at the moment then Windows 7 will not waste time by running that program in the background. It will wait until you have plugged it in.

The latest version of a series of Operating Systems that Microsoft has produced for use on personal computers.

It is the follow-up to the Windows Vista Operating System which was released in 2006. An operating system allows your computer to manage software and perform essential tasks.

It is also a Graphical User Interface (GUI) that allows you to visually interact with your computer’s functions in a logical, fun and easy way.

For example, in Windows 7 you can view two windows side by side by using the Aero Snap feature. This feature automatically sizes or snaps two windows to fit together on the screen thus allowing you the convenience of viewing them next to each other.

the Main element of  the Window 7 are the following 

The main components of the window  7 are the following

§   Aero view

§  Taskbar

§  Search

§  Liabriries

§  Gadgets

Aero

Is the interface that makes  your visual interactions with  the desktop fun and more easy.

Aero peek

Makes  Ur open window transport so U may see your desktop . it also allows the user to peek  at items in your taskbar for thumbnail view.

Aero Snap

Is a quick way to resize your window to make them easier to read , organize and compare.

Aero flip

Allows U to  preview all your open windows for Central window or 3 D view that u can flip through .

Aero Shak

Allows U to take your mouse and shake only the open window you want to focus on and the rest will disappear. 

Taskbar 

In the computing the taskbar is the displayed on the full edge of GUI( graphical user interface ) desktop  that is used to launch the monitor running application . it was 1^st time introduced by Microsoft in 1995  

network

what is network ?

A network is a group of two or more computer system linked together. Computer on the network are sometimes called as Nodes

B

basically 

 Basically there are 3 types of the computer network can be called ass
LAN( Local area network )
WAN ( Wide area network)
MAN ( Metropolitan area network)

LAN (Local area network) 

LAN’s can be either wired or wireless. Twisted pair,coax or fibre optic cable can be used in wired LAN’s.
• Every LAN uses a protocol – a set of rules that governshow packets are configured and transmitted.
• Nodes in a LAN are linked together with a certaintopology. These topologies include:
– Bus
– Ring
– Star
• LANs are capable of very high transmission rates (100sMb/s to G b/s).

MAN ( Metropolitan area network) 

A metropolitan area network (MAN) is a large computer network that usually spans a city or a

large campus

§  A MAN Is optimized for a large geographical area than LAN ranging from several block  of Building to entire cities.

A MAN  might is owned and operated by a single organization . But is usually used by  many individual and organizations 

WAN (wide area network)

 WAN covers a large geographic area such as country, continent or even whole of the world.

• A WAN is two or more LANs connected together
. The LANs can be many miles apart

• To cover great distances, WANs may transmit data over leased high-speed phone lines or

wireless links such as satellites.

. Personal Area Network (PAN)

• A PAN is a network that is used forcommunicating among computers and computer

devices (including telephones) in closeproximity of around a few meters within a room

• It can be used for communicating between thedevices themselves, or for connecting to a larger

network such as the internet.

• PAN’s can be wired or wireless
