Wi-Fi Hotspots

A Wi-Fi hotspot is a wireless access point that provides Internet access to network devices in public locations such as downtown centers, cafes, airports and hotels. Businesses and schools are increasingly using Wi-Fi hotspots for their internal (intranet) networks. Home wireless networks also use similar Wi-Fi technology.

Create Your Own Little Windows Start Menu

Displaying a folder's contents on the taskbar is an old but good function of Windows.
It is almost as useful as the quick launch part of the taskbar which is hidden by default, therefore many users simply ignore its existence.
Quickly locating some frequently accessed shortcuts or documents and executing them, is a critical task for any operating system. From my experience, most casual users are usually creating shortcuts on their desktops. While this is a quick and easy solution, it just clutters their desktops making it impossible to locate something after some time of use.

There are many reasons why Mozilla Firefox is considered by many to be the best browser in the market today mainly because of the wide customization options available to the users.
One of them is the ability to control the location of the whole application data using profiles.
Why is this important and useful?
All of user's local settings, plug-ins, browsing history, saved passwords and bookmarks are stored in a specific folder.
This folder is stored in Firefox's application data directory by default under a default user folder.
Changing this, gives user the flexibility of using different versions of the browser using different plug-ins and passwords.
If you are concerned about security of your passwords for example, you have the ability to create a new non default profile running only by you using a special shortcut. The default profile will remain unchanged, so if you're using a public computer no one without access to your shortcut will be able to run Firefox with your private profile data.
How to do it
* First of all you need to run the Firefox profile manager. So create a new Firefox shortcut on your desktop, or copy and paste an existing one.
* Right click on the shortcut and select properties.
* In the target box add " -profilemanager" (without the quotes) to the end of the existing contents and press OK.
* Now run the newly created shortcut and the profile manager will appear with the default user's profile selected.
* Click the Create profile button. In the next screen enter a name for your new profile and press the choose folder button to select the location of your data.
* Press Finish. The new profile will appear in the profiles list. If you want to use the new profile as the default, select it, check the don't ask at startup checkbox below and click start Firefox.
* If you want to run your Firefox new profile using a shortcut, create a new shortcut for Firefox or copy/paste an existing one and add " -P yourProfileName" at the end of the existing target text box. (eg. "C:Program FilesMozilla Firefoxfirefox.exe" -P myOwnProfile)
Advantages
Using this method you can have all your Firefox specific profile data in a folder of your choice, meaning that you can manage it and get backups easily. You can also create profile specific shortcuts and run lighter profiles with no plug-ins for faster browsing or private profiles if you protect your shortcut.
Please note: Firefox cannot run multiple profiles simultaneously. To run under a different user profile you have first to close all open windows.

Computers Basics

Computers are showing up everywhere you look, and even in places you can't see. Computers check out your groceries, pump your gas, dispense money at the ATM, turn the heat on and off, control the way your car runs. They're everywhere! They're everywhere!
In fact, the computer is rapidly becoming, if it hasn't already gotten there, as tightly woven into the fabric of our lives as the automobile. The analogy runs quite deep.
When automobiles were new, many people said "Those smelly, loud, complicated things will never replace the horse!" And "Those things break down in just a few miles, while my faithful horse goes on and on and repairs itself!" Nowadays it's hard to imagine the world without all the variety of four-wheeled, internal combustion vehicles. How many can you name? Sedans, pickup trucks, fire engines, front-end loaders, 4-wheelers, golf carts, bulldozers, cranes, vans, dump trucks... We have an "automobile" for every purpose under heaven - and in different models and colors, too.

What is a computer?

A computer is an electronic device that executes the instructions in a program.
A computer has four functions:

a. accepts data	Input	The Information Processing Cycle
b. processes data	Processing
c. produces output	Output
d. stores results	Storage
In the lessons that follow we will study the parts of the computer and each of the four parts of the Information Processing Cycle.

History Of Computer #2

Prehistoric man did not have the Internet, but it appears that he needed a way to compute and make calculations. The limitations of the human body’s ten fingers and ten toes apparently caused early man to construct a tool to help with those calculations. Scientists now know that humankind invented an early form of computers. Their clue was a bone carved with prime numbers found in 8,500 BC.
The abacus was the next leap forward in computing between 1000 BC and 500 BD. This apparatus used a series of moveable beads or rocks. The positions changed to enter a number and again to perform mathematical operations. Leonardo DaVinci was credited with the invention of the world’s first mechanical calculator in 1500. In 1642, Blaise Pascal’s adding machine upstaged DaVinci’s marvel and moved computing forward again.
In 19^th century England, Charles Babbage, a mathematician, proposed the construction of a machine that he called the Babbage Difference Engine. It would not only calculate numbers, it would also be capable of printing mathematical tables. The Computer History Museum in Mountain View, CA (near San Diego) built a working replica from the original drawings. Visitors can see in the device in operation there. Unable to construct the actual device, he earned quite a few detractors among England’s literate citizens. However, Babbage made a place for himself in history as the father of computing. Not satisfied with the machines limitations, he drafted plans for the Babbage Analytical Engine. He intended for this computing device to use punch cards as the control mechanism for calculations. This feature would make it possible for his computer to use previously performed calculations in new ones.

History of Computers

The development of the modern day computer was the result of advances in technologies and man's need to quantify. Papyrus helped early man to record language and numbers. The abacus was one of the first computing machines..
Some of the earlier mechanical computing machines lacked the technology to make the design work. For instance, some had parts made of wood prior to metal manipulation and manufacturing. Imagine the wear on wooden gears. This history of computers site includes the names of early pioneers of math and computing and links to related sites about the History of Computers, for further study. This site would be a good Web adjunct to accompany any book on the History of Computers or Introduction to Computers. The "H" Section includes a link to the History of the Web Beginning at CERN which includes Bibliography and Related Links.
