Slang sometimes used to describe a computer. For example, someone may say "I'm making a gaming rig!", which is another way of saying they're in the process of building or buying a computer meant for computer gaming.

Password manager

Software utility used to store and manage the passwords you use to log into online services such as your banking account. What makes a password manager unique when compared to simply just storing your username and password information in a text file is that these programs will encrypt all login information and will only un-encrypt the data if you know the master password. To the right is an example of the KeePass login page to access all stored passwords.


Software feature found in Image and Paint editors that allows the user to paint on the image they're currently viewing. Using a paintbrush users can make edits to the image or create something new on the image such as giving someone a mustache. To the right is an example of what the paintbrush icon commonly looks like in most paintbrush programs.

Hidden partition

Sometimes referred to as the recovery partition, the hidden partition is a type of partition often found on OEM computers such as Acer, ASUS, Dell, eMachine, and HP (Compaq) computers that allows the user to restore their computer back to how it was when they first received their computer without the need of a CD or DVD. Hidden partitions are accessed either through Windows using a pre-installed application that came with the computer or by pressing a key combination as the computer boots up. Below are some examples of how to access this partition as the computer is booting up. Often it's easiest to simply press the key mentioned below over and over as the computer is booting up or if it's two keys holding down the modifier key and then pressing the other key over and over.

  • Alt + F10 - Access Acer disk-to-disk (D2D) recovery partition. Note: you may need to enable the D2D option in CMOS setup.
  • F9 - Access ASUS EEE PC hidden partition.
  • F11 - Access the Compaq (Hewlett Packard) recovery partition.
  • Ctrl + F11 or F8 - Access Dell computers Dell System Restore (DSR) partition on many different models.
  • F11 - Access eMachine option to restore backup copy.
  • F11 - Access Gateway hidden restore partition
  • F11 - Access Lenovo hidden recovery partition.
  • F10 - Access Sony hidden restore partition.
  • 0 (zero key) or F8 - Access Toshiba hidden partition.

Finally, you may have the option between a Non-Destructive System Restore and Full System Restore. For computers that have the Non-Destructive System Restore option or an option similar, we suggest trying this option first. This can resolve a lot of Windows related issues without erasing of your personal data such as family photos. For more serious issues or if the non-destructive option doesn't work do a Full System Restore. This will delete all files on your computer however will resolve any issue your computer

TipIf your computer did not come with this hidden partition or you've deleted it the only way to restore your computer would be to use a Windows CD and boot from that CD. However, this will only re-install Windows and not any of the other software or drivers that came with your computer.


Short for Function, the Fn key is a keyboard key found on laptop computers that allows you to perform special functions on the laptop such as turning up the brightness or contrast, switching video modes, and/or printing the screen.

Above is an example of the Fn keyboard key found on a laptop. As can be seen in this example the laptop has a color coded Fn key and matching colors on the keys with symbols symbols representing what the keys do. In this example pressing and holding down the Fn key and pressing the up or down arrows would increase or decrease the brightness. Other laptops may have the Fn key with a square around it and similar symbols on other keys such as the F7 and F8 key.

What to do when getting artifacts?

This can depend on where you're encountering the artifacts. Below are some general suggestions in troubleshooting artifact related issues.

  1. Check connections. Disconnect and re-connections to ensure firmly connected.
  2. If your computer monitor is displaying artifacts regardless of what program you're in try a different monitor on the computer. If same issues persist make sure you've got the latest video drivers and that your video card is firmly connected into the computer.
  3. If you're digital camera is generating artifacts in your pictures make sure you quality is set to the highest possible quality. If all settings are set to their highest quality and all pictures you take have artifacts it's likely a digital camera limitation or issue with the camera.
  4. If you're getting artifacts when compressing or changing a video from one format to another try a different format.
  5. If you're getting artifacts on your TV display and have cable or a satellite connection make sure you're getting a strong signal. Often it's best to contact your provider to verify your connection is good and strong.


More commonly known as a digital artifact, when referring to computers and electronics. An artifact is any type of error or glitch that occurs during a signal transmission or interpretation. Some examples of where you may encounter artifacts include: artifacts generated when taking a picture with a digital camera, artifacts that randomly occur during the transmission of a digital image and/or audio, and artifacts created from the compression of a signal or data.

What about a hardware firewall?

If you have a firewall on your router or have another hardware firewall it is ok if the Windows Firewall is left enabled. Because this is not a software program running on your computer it will not cause any conflicts.

Should I disable the Windows Firewall if I install another one?


Should I disable the Windows Firewall if I install another one?


Yes. Just like an anti-virus your computer should only have one software firewall enabled and running. Having more than one firewall can cause conflictions and often will prevent your Internet from working properly.


Sometimes abbreviated as NVRAM, non-volatile memory is any type of memory or storage that will be saved regardless if the power to the computer is on or off. The best example of non-volatile memory and storage is a computer hard disk drive. If data is stored on a hard disk drive it'll remain on that drive regardless if the power is interrupted, which is why it's the best place to store your data.

Hard Drive

Inside a computer hard disk drive

Hard drive

The computer's main storage media device used to permanently store all data on the computer. Also referred to as a hard disk drive or abbreviated as HD or HDD, the hard drive was first introduced on September 13, 1956 and consists of one or more hard disk platters inside of air sealed casing. Most hard drives are permanently stored in an internal drive bay at the front of the computer and are connected with either ATA, SCSI, or a SATA cable and power cable. Below is an illustration of the inside of a hard disk drive.

A hard disk drive

a non-volatile storage device for digital data. It features one or more rotating rigid platters on a motor-driven spindle within a metal case. Data is encoded magnetically by read/write heads that float on a cushion of air above the platters.

Hard disk manufacturers quote disk capacity in SI-standard powers of 1000, wherein a terabyte is 1000 gigabytes and a gigabyte is 1000 megabytes. With file systems that measure capacity in powers of 1024, available space appears somewhat less than advertised capacity.

Understanding the Field of Communication

The field of communication is typically broken into three distinct camps: human communication, mass communications, and communication disorders.

Visual communication

Visual communication is communication through visual aid. It is the conveyance of ideas and information in forms that can be read or looked upon. Primarily associated with two dimensionalimages, it includes: signs, typography, drawing, graphic design, illustration, colour and electronic resources. It solely relies on vision. It is form of communication with visual effect. It explores the idea that a visual message with text has a greater power to inform, educate or persuade a person. It is communication by presenting information through visual form.


A major feature of social communication is eye contact. It can convey emotion, signal when to talk or finish, or aversion. The frequency of contact may suggest either interest or boredom.


One of the most frequently observed, but least understood, cues is a hand movement. Most people use hand movements regularly when talking. While some gestures (e.g., a clenched fist) have universal meanings, most of the others are individually learned and idiosyncratic.

Facial Expressions

A smile, frown, raised eyebrow, yawn, and sneer all convey information. Facial expressions continually change during interaction and are monitored constantly by the recipient. There is evidence that the meaning of these expressions may be similar across cultures.

Physical Contact

Shaking hands, touching, holding, embracing, pushing, or patting on the back all convey messages. They reflect an element of intimacy or a feeling of (or lack of) attraction.


Obviously one can be lying down, seated, or standing. These are not the elements of posture that convey messages. Are we slouched or erect ? Are our legs crossed or our arms folded ? Such postures convey a degree of formality and the degree of relaxation in the communication exchange.


People may present themselves in various ways: face-to-face, side-to-side, or even back-to-back. For example, cooperating people are likely to sit side-by-side while competitors frequently face one another.


The distance one stands from another frequently conveys a non-verbal message. In some cultures it is a sign of attraction, while in others it may reflect status or the intensity of the exchange.


This is the type of communication that makes use of religious, status, or ego-building symbols.


This is the mechanical type of communication, which includes the use of signal flags, the 21-gun salute, horns, and sirens.


This is the type of communication that takes place through creative expressions: playing instrumental music, dancing, painting and sculpturing.


This is the personal type of communication. It includes facial expressions, tone of voice, sense of touch, sense of smell, and body motions.

Nonverbal communication

Nonverbal communication is the process of communicating through sending and receiving wordlessmessages. Such messages can be communicated through gesture, body language or posture; facial expression and eye contact, object communication such as clothing, hairstyles or even architecture, or symbols and infographics, as well as through an aggregate of the above, such as behavioral communication. Nonverbal communication plays a key role in every person's day to day life, from employment to romantic engagements.

Human communication

Human spoken and written languages can be described as a system of symbols (sometimes known as lexemes) and the grammars (rules) by which the symbols are manipulated. The word "language" is also used to refer to common properties of languages. Language learning is normal in human childhood. Most human languages use patterns of sound or gesture for symbols which enable communication with others around them. There are thousands of human languages, and these seem to share certain properties, even though many shared properties have exceptions.

There is no defined line between a language and a dialect, but the linguist Max Weinreich is credited as saying that "a language is a dialect with an army and a navy". Constructed languages such asEsperanto, programming languages, and various mathematical formalisms are not necessarily restricted to the properties shared by human languages.

Information communication revolutions

Over time, technology has progressed and has created new forms of and ideas about communication. The newer advances include media and communications psychology. Media psychology is an emerging field of study. These technological advances revolutionized the processes of communication. Researchers have divided how communication was transformed into three revolutionary stages:

In the 1st Information Communication Revolution, the first written communication began, with pictographs. These writings were made on stone, which were too heavy to transfer. During this era, written communication was not mobile, but nonetheless existed.


process of transferring information from one entity to another. Communication processes are sign-mediated interactions between at least two agents which share a repertoire of signs and semiotic rules. Communication is commonly defined as "the imparting or interchange of thoughts, opinions, or information by speech, writing, or signs"[by whom?].

Communication is a process whereby information is enclosed in a package and is channeled and imparted by a sender to a receiver via some medium. The receiver then decodes the message and gives the sender a feedback. All forms of communication require a sender, a message, and an intended recipient, however the receiver need not be present or aware of the sender's intent to communicate at the time of communication in order for the act of communication to occur.

CSC Positioned in 'Leaders'

FALLS CHURCH, Va., Jul 13, 2010 (BUSINESS WIRE) -- CSC (CSC 46.96, +1.09, +2.38%)announced today that it has been positioned in the "leaders" quadrant of the Gartner report, Magic Quadrant for Communications Outsourcing and Professional Services (COPS), North America. The report published on June 30, 2010, reviewed 16 vendors of information technology (IT) services for business communications systems in North America.


Digital technologists concern themselves with data - conventional representations of facts or ideas - and with machines for storing, transforming, and transmitting it. Although computing professionals also concern themselves with digital technology, they focus primarily on people and information-the meaning that people give to data. The use of data to convey information is vitally important to our social systems. This is underlined by recent research showing that dogs are much more able to get meaning from data than chimpanzees,
