ENCRYPTION

Encryption is the conversion of data into a form, called a cipher text, that cannot be easily understood by unauthorized people. Simple ciphers include the substitution of letters for numbers, the rotation of letters in the alphabet, and the “scrambling” of voice signals by inverting the sideband  frequencies. More complex ciphers work according to sophisticated computer algorithms that rearrange the data bits in digital signals.Decryption is the process of converting encrypted data back into its original form, so it can be understood.

EMAIL

An application or program that runs on a personal computer or workstation and enables you to send, receive and organise electronic mail. Email systems are based on a client-server architecture. Mail is sent from many clients to a central server, which re-routes the mail to its intended destination. Microsft’s Outlook is one example.  Send me an email. lynwebster@optusnet.com.au

The two most important forms of editable text are rich text and global text.

ENCODING

To format (electronic data) according to a standard format.

FACEBOOK

Facebook is a social networking wesite. Mark  Zuckenberg first launched Facebook  in February 2004. The site was initially built only for the students of Harvard who where genuinely interested in keeping track of their friends and sharing their photos, views and news with them.
Though initially the site was for Harvard people only, within a month, more than half of the Harvard was a member of Facebook. Then Zuckenberg was joined by Dustin and Moscovitz and Chris Hughes and the site expanded to Stanford, Columbia and Yale Universities too. Gradually more universities and schools started coming under its umbrella. It started accepting all users who have a university e-mail id.
Finally, the overwhelming response to Facebook forced its founders to open up the forum to all. And from September 2006, Facebook opened registration to everyone with a valid e-mail address.

In May 2007, Facebook allowed free posting of classified ads by its users. This feature is known as Facebook marketplace, users can post ads on lease, rent, vehicles, property etc. in ‘Available’ or ‘Wanted’ format. In the year 2007, Facebook has already added certain other features, that of Facebook platform being a unique one. Here users are encouraged to develop applications to be used on Facebook.

FIXED WIRELESS

Fixed wireless refers to the operation of wireless devices or systems in fixed locations such as homes and offices. Fixed wireless devices usually derive their electrical power from the utility mains, unlike mobile wireless or portable wireless which tend to be battery-powered.

FORMS

FTP APPLICATIONS

Acroynm for File Transfer Protocol. This is a standard way of transferring files from one computer to another on the Internet.  It is also used for uploading pages to a web site.

FTP ANONYMOUS SERVER

Using the Internet’s File Transfer Protocol (FTP), anonymous FTP is a method for giving users access to files so that they don’t need to identify themselves to the server. Using an FTP program or the FTP command interface, the user enters “anonymous” as a user ID. Usually, the password is defaulted or furnished by the FTP server. Anonymous FTP is a common way to get access to a server in order to view or download files that are publicly available.

FILE SIZE

The digital size of an image, measured in kilobytes (K), megabytes (MB), or gigabytes (GB). File size is proportional to the pixel dimensions of the image. Images with more pixels may produce more detail at a given printed size, but they require more disk space to store and may be slower to edit and print. For instance, a 1-by-1-inch, 200-ppi image contains four times as many pixels as a 1-by-1-inch, 100-ppi image and so has four times the file size. Image resolution thus becomes a compromise between image quality (capturing all the data you need) and file size.

FREEZE

What one does when my excellent teacher enquires if my blog is completed?

An unexpected halt of a computer while running an application program. A frozen or “hung” machine is characterised by a total lack of response from the mouse and keyboard. The user can almost never effect a recovery except by turning the computer off and restarting it.

FILE EXTENSION

A file extension is the set of characters following the right-most period in a filename. It is  used to determine a file’s format which in turn assists the operating system in determining which application to use to open file.

FIREWALL

A firewall prevents unauthorised access to or from a private network.  A firewall can be installed either via hardware or software or a combination of both and it is designed to prevent and filter unauthorised access via the internet to a private network.

FORMAT

The structure that defines how data is organized in a software file used to store information about a particular file. A standardized file format makes it possible for different software programs to share the same information
