Computer Basics - Accelerators and web slices

Accelerators and web slices are types of add-ons available for Internet Explorer. Accelerators allow you to
translate, search for, or map text you've selected in the browser. Web slices give you real-time updates for
specific websites in your Favorites bar. For example, you could use a web slice to get quick updates on
sports scores or the weather forecast.
In our experience, web slices don't work consistently and aren't available for many websites, so
their usefulness may be limited.

Basics of electronic mail
What is an electronic mail ?
Electronic mail, most commonly referred to as email or e-mail since ca. 1993,[2] is a method of
exchanging digital messages from an author to one or more recipients. Modern email operates across the
Internet or other computer networks. Some early email systems required that the author and the recipient
both be online at the same time, in common with instant messaging. Today's email systems are based on
a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users
nor their computers are required to be online simultaneously; they need connect only briefly, typically to a
mail server, for as long as it takes to send or receive messages.
Email Addressing
A name that identifies an electronic post office box on a network where e-mail can be sent. Different types
    of networks have different formats for e-mail addresses. On the Internet, all e-mail addresses have the
    form:
@<domain name >
 
Mailbox – Inbox and Outbox
An area in memory or on a storage device where e-mail is placed. In e-mail systems, each user has a
private mailbox. When the user receives e-mail, the mail system automatically puts it in the mailbox.
The mail system allows you to scan mail that is in your mailbox, copy it to a file, delete it, print it, or

forward
it to another user. If you want to save mail, it is a good idea to copy it to a file, because files tend to be
more stable than mailboxes.
