• E-services, a business concept developed by Hewlett Packard (HP), is the idea that the
World Wide Web is moving beyond e-business and e-commerce (that is, completing sales
on the Web) into a new phase where many business services can be provided for a
business or consumer using the Web. Some e-services, such as remote bulk printing, may
be done at a Web site; other e-services, such as news updates to subscribers, may be sent
to your computer. Other e-services will be done in the background without the
customer's immediate knowledge. HP defines e-services as "modular, nimble, electronic
services that perform work, achieve tasks, or complete transactions."
• On the Internet, chatting is talking to other people who are
using the Internet at the same time you are. Usually, this
"talking" is the exchange of typed-in messages requiring
one site as the repository for the messages (or "chat site")
and a group of users who take part from anywhere on the
Internet. In some cases, a private chat can be arranged
between two parties who meet initially in a group chat.
Chats can be ongoing or scheduled for a particular time
and duration. Most chats are focused on a particular topic
of interest and some involve guest experts or famous
people who "talk" to anyone joining the chat.
• A videoconference is a live connection between
people in separate locations for the purpose of
communication, usually involving audio and
often text as well as video. At its simplest,
videoconferencing provides transmission of static
images and text between two locations. At its
most sophisticated, it provides transmission of
full-motion video images and high-quality audio
between multiple locations.
• A blog (short for weblog) is a personal online journal that
is frequently updated and intended for general public
consumption. Blogs are defined by their format: a series of
entries posted to a single page in reverse-chronological
order. Blogs generally represent the personality of the
author or reflect the purpose of the Web site that hosts the
blog. Topics sometimes include brief philosophical
musings, commentary on Internet and other social issues,
and links to other sites the author favors, especially those
that support a point being made on a post.
• A newsgroup is a discussion about a particular
subject consisting of notes written to a central
Internet site and redistributed through Usenet, a
worldwide network of news discussion groups.
Usenet uses the Network News Transfer Protocol
• Newsgroups are organized into subject
hierarchies, with the first few letters of the
newsgroup name indicating the major subject
category and sub-categories represented by a
• E-Learning is training that takes place through a network,
usually over the Internet or a company's intranet. It has its
roots in the world of computer-based training that
appeared in the early 1980s and used CD-ROMs to teach
mostly technical skills to mostly technical people. Lately, e-
learning has changed to be a tool widely used in both the
academic and corporate worlds. With today's e-learning,
companies can train salespeople to use a new product, even
if offices are in distributed locations. On the academic
front, e-learning allows people to take online courses from
universities in various subjects.
• The act of purchasing products or services over
the Internet. Online shopping has grown in
popularity over the years, mainly because people
find it convenient and easy to bargain shop from
the comfort of their home or office. One of the
most enticing factor about online shopping,
particularly during a holiday season, is it
alleviates the need to wait
in long lines or search from store to store for a
• Social networking is the practice of expanding
the number of one's business and/or social
contacts by making connections through
individuals. While social networking has gone on
almost as long as societies themselves have
existed, the unparalleled potential of the Internet
to promote such connections is only now being
fully recognized and exploited, through Web-
based groups established for that purpose.
