Browser


Alternatively referred to as a web browser or Internet browser, a browser is a software program created as a simplified means to present and explore content on the World Wide Web. These pieces of content, including pictures, videos, and web pages, are connected using hyperlinks and classified with URIs (Uniform Resource Identifiers).
There have been many different web browsers that have come and gone over the years. The first, named WorldWideWeb (later changed to Nexus), was invented by Tim Berners-Lee in 1990. However, the first graphical browser and widely used browser that help bring popularity to the Internet was NCSA Mosaic.

What is needed for a browser to work?
A browser needs a computer, smartphone, or tablet that meets the system requirements and that has a working Internet or intranet connection that allows it to connect to other computers.
Getting around in a browser
Each browser has a navigation toolbar that helps you find your way around the Internet. As seen in the images below, the navigation toolbar has undergone significant changes to streamline its appearance and functionality. However, the toolbar is likely never going to lose the navigation arrows and address bar.


Overview of browser bar buttons, menus, and functions
As we mentioned in the previous section, over time, many Internet browser buttons and options have either been moved or done away with completely. Consequently, some of the options mentioned below may not be immediately visible on your browser.
Tip
In certain browsers, pressing the Alt key on your keyboard shows hidden options.
Settings (menu)
Nearly all modern browsers today have moved advanced options and features in the upper-right or left corner of the browser window. Each browser's menu button is different:
For example, Internet Explorer uses , Chrome uses , Firefox uses , and Opera uses .
How to access Internet browser settings.
Back
The back button visits the previous page that referred you to the page you are currently viewing. This button often resembles an arrow pointing to the left.
Why does my Internet back button sometimes not work?
Creating an HTML back button.
Forward
The forward button moves you forward a page. It only works if you have previously used the back button. If you have not gone back, and your browser shows a forward button, it will be grayed out.
Stop
The stop button no longer exists in the majority of modern web browsers. However, its function (to stop a web page from loading) may still be executed by pressing the Esc key.
Refresh (reload)
As you browse the Internet the browser cache's data it downloads, meaning they store some or all parts of each page you visit on your computer. This feature is useful as it allows users to not have to download the full page each time they visit the same site. On some sites, you may want to refresh the page to get the latest version (e.g., on a news site). The Refresh button can also be used to reload a page that has failed to load because of an error.
Tip
Press the F5 key or Ctrl+R to refresh the page from the keyboard. If the F5 key is not working, you can also do a force reload by pressing Ctrl+F5 in Windows or on an Apple computer press command+R.
Home
The Home button is used to return users to their default web page; the same page that loads when the browser is first opened.

SearchIn the past, the Search button was used to open a user's default search page or execute a search on the text found in the address or URL text field. Today's browsers have what is called an omnibox, which is a search function built into the address bar.
 

FullscreenThis function is used to make the browser window a fullscreen; temporarily removing the toolbar, buttons, and address bar. Often, this view mode may be toggled on and off by pressing the F11 key on your keyboard.
 

HistoryThis feature allows users to view the pages that have been visited since the browser history was last cleared or created. All your saved pages are stored in your Internet cache.
 

How do I clear my Internet browser history?
 

Tip
The shortcut key for history for most browsers is Ctrl+H.
 

Favorites (bookmarks)This folder stores websites or pages chosen by the user. The term "Favorites" is used with Microsoft Internet Explorer; in other browsers this may be known as bookmarks or a hotlist.
 

How do I create an Internet favorite or bookmark? 
PrintThis feature, although no longer a button and may be accessed through the main settings menu or pressing Ctrl+P on the keyboard.
 

How to print a web page. 
Font (size)This button no longer exists but was used to increase or decrease the size of a font; an option now covered by the zoom feature.
 

ZoomOn modern browsers, holding down the Ctrl key and pressing either the "+" (plus key) or "-" (minus key) zooms in or out, increasing and decreasing the size of font and images. To reset the zoom function to its default size, press Ctrl+0 (zero) at the same time.
 

MailUsed to open a user's preferred e-mail program. Today, this option is no longer found in browsers.
 

EditUsed to open and edit the web page you are currently viewing in an HTML editor. Today, no longer found in browsers.

Excel Microsoft Office Excel spreadsheet Microsoft Excel

Excel

Code-named Odyssey, Excel is a software program from Microsoft that is part of the Microsoft Office suite of productivity software developed by Microsoft. Released on September 30, 1985, Excel is capable of creating and editing spreadsheets that are saved with a .xls or .xlsx file extension. General uses of Excel include cell-based calculation, pivot tables, and various graphing tools. For instance, with an Excel spreadsheet, you could create a monthly budget, track business expenses, or sort and organize large amounts of data.
Unlike a word processor, such as Microsoft Word, the Excel documents consist of columns and rows of data, made up of individual cells. Each of these cells can contain either text or numerical values that can be calculated using formulas.

Excel overview
Below is an example of Microsoft Excel with each of its major sections highlighted. See the formula bar, cell, column, row, or sheet tab links for further information about each of these sections.











How can Excel be formatted?
Each of the rows, columns, and cells can be modified in many ways, including the background color, number or date format, size, text font, layout, etc. In our above example, you can see that the first row (row 1) has a blue background, bold text, and each cell has its text centered. 


Download an example of a spreadsheet file

 
We've created a Microsoft Excel spreadsheet that can be downloaded and opened in any spreadsheet program including Microsoft Excel. This spreadsheet helps illustrate some of the capabilities of a spreadsheet, formulas, and functions used in a spreadsheet and allows you to experiment more with a spreadsheet.





 





Why do people use Excel?
There are many reasons people may use Excel (a spreadsheet program). For example, someone might use Excel to keep track of their expenses. For a full list of reason and examples of how people use a spreadsheet, see our spreadsheet definition.


Why would someone use Excel over a different spreadsheet program?
Today, there are many different free spreadsheet options that someon
e could use instead of Excel. However, even with the available free options, Excel remains the most used spreadsheet because of all its available options, features, and because many businesses still use the program.


Tip
Even with all Excel's options for most people a free spreadsheet program like Google Sheets is often all most users need.
Note
If you want to get Excel because it is a job requirement, it is still ok to learn all the basics in a free spreadsheet program. However, there are still many differences between Excel and a free spreadsheet program.

Use the Windows Magnifier to zoom in on parts of your screen.

Use the Windows Magnifier to zoom in on parts of your screen.

The Windows Magnifier is a great accessibility tool that allows you to zoom into any portion of your screen you find hard to read. This feature can be found in the Control Panel in the Ease of Access Center. It can also be quickly accessed by holding down the Windows key and pressing the + (plus) key to zoom in or - (minus) key to zoom out. When enabled, the Magnifier box and the current magnification will be shown, as seen in the picture.



Zoom

Zoom may refer to any of the following:

1. When referring to an image or graphic, zoom describes the function of focusing on a section of an image and increasing its overall size to manipulate or view in greater detail. The image at right is zoomed in 1600% of its original size.
As can be seen in the image, as you zoom into an image each of the pixels that make up the image grow and make the image appear pixelated or jaggy. Unfortunately, unlike in the movies, you cannot "enhance" the image to make a zoomed image clearer.
Tip
Many graphics programs and Internet browsers support the keyboard shortcut key "Ctrl+minus key" to zoom out and "Ctrl+plus key" to zoom in on a picture or web page. Also, "Ctrl+0" (the number zero) will reset the zoom to the default zoom level.
