Cluster

1. When referring to a hard drive, a cluster or file allocation unit is the smallest managed section of a hard drive that holds a file. The size of a hard drive cluster can vary by operating system and size of hard drive.

Because each file and directory takes up one or more clusters depending on their size, earlier versions of FAT had the potential of wasting hard drive space. For example, if the cluster size was 8k and a 2k file is stored on the computer, 6k of that cluster will go to waste.

This issue has been reduced with new versions of FAT have been made available such as FAT32 that help resolve this issue. Additional information about FAT32 can be found on our FAT32 page.

2. A cluster may also be used to define a group of computers or servers that share the work as one. Making one big computer instead of multiple smaller computers. In the picture, is an example of cluster of rack mountable computers at the NCSA/University of Illinois.

Docking station

Alternatively referred to as a universal port replicator, a docking station is a hardware device that allows portable computers to connect with other devices with little or no effort. Docking stations enable users with a laptop computer to convert it into a desktop computer when at the office or at home. For example, a user could use their laptop while on the road and then when at the office connect the laptop to the docking station and use their 19" monitor, speakers, and office printer without having to transfer any of the data they may have been working on while on the road. In the picture to the right, is an example of a Dell docking station, this particular docking station enables the laptop to be directly connected to the docking station without the need of using any additional cables. Keep in mind that all docking stations are different.

Dock -Term used to describe the process of connecting a portable computer to a docking station.

Undock (cold dock) - Term used to describe the process of disconnecting a portable computer from a docking
                                     station after it has been shut down.

E ink

1. Hardware company founded in 1997 with research that started at the MIT Media Lab that develops Electronic Paper Displays (EPD) technologies found in such products as the Amazon Kindle. As can be seen in the picture example, this technology works by positively charging white pigment chips and negatively charging black pigment chips and storing those chips in a clear fluid. When a negative electric field is applied the white pigment chips move to the top and makes the surface appear white, and the opposite eclectic field moves the black pigment chips to the surface.

2. Electronic Paper is also the code name Microsoft used for Multiplan.

Excel

Codenamed Odyssey, Excel is a software program capable of creating and editing spreadsheets that are saved with a .xls file extension. For example, with a spreadsheet you could create your own payroll, balance your check book, organize a large amount of data in an easy to read format, and much more. This is done by adding, subtracting, multiplying, and dividing the values in the spreadsheet to view overall totals and create graphs based on that data.

Unlike a word processor such as Microsoft Word, the Excel documents are created with several hundred columns and rows that break down to several thousand cells. These can be modified by color, number format, size, fonts, layout, and thousands of additional available options. In the below picture, is an example of what Microsoft Excel may look like.

UDP

Short for User Datagram Protocol and defined in RFC 768, UDP is an alternative protocol to the TCP/IP that runs on top of IP and is sometimes referred to as UDP/IP. Unlike TCP/IP, UDP does not divide each transmission into packets, which allows for a faster transmission. However, UDP does not provide error checking.

LOL

1. Shorthand for Laughing out Loud or Laugh out Loud, LOL is the most commonly used chat expressions to illustrate you are laughing during a text conversation or that you found something funny. LOL is also less commonly short for Lots of Laughter and Laughing on Line and is also often substituted by LAL, LAWL (Laughing a Whole Lot), LOLZ, LUL and LULZ. Although already an abbreviation LOL is also sometimes abbreviated even more as LL.

Finally, LAWL is also used as a slang term that phonetically spells out 'lol'. This is often said in the real life or over VoIP by someone who may type in lol a lot in chat.

2. Although not as common as the above definition of LOL, this term can also mean Lots of Love and may be something added at the end of an e-mail, letter, or other correspondence.

3. Short for Lots of Luck, LOL is another way of wishing someone good luck. This term could also be used sarcastically as telling someone they don't have a chance.

GIF

Pronounced jiff and short for Graphic Interchange Format, GIF is a file extension and a bit-mapped graphics file introduced by CompuServe in 1987 and today one of the most commonly used images on the Internet. The original release of the GIF standard is known as the GIF87a version. This standard was later replaced in 1989 when CompuServe released an improved version known as GIF89a. This improved version supported animation and transparent images.

On December 24, 1994 Unisys and CompuServe announced that they expected licensing fees for software that creates and displays GIF images. This caused a lot of hysteria among developers and website owners using GIF images because of potential future GIF taxes, this hysteria lead to the development of the PNG format. The Software Freedom Law Center announced that after October 1, 2006 all significant patent claims interfering with the employment of the GIF format will expire, and all users should have no concerns about using the format.

Digitize

Digitize is the process of converting an image or text into digital data for storing. A good example of digitizing is when a computer scanner converts a non-digital image, such as a picture family picture into a binary image file on the computer.

CD-R

Alternatively referred to asa cd writer, CD-WO (Write once), WORM (Write Once Read Many) drive. CD-R is short for CD-Recordable and is a writable disc and drive that is capable of having information written to the disc once and then having that disc read many times after that. If the data is not written to the disc properly, has errors, or has the incorrect information that disc or portions of that disc cannot be erased and is often jokingly referred to as a coaster.

A CD-R disc is coated with a photosensitive organic dye that allows a user to record information. Once the CD-R disc is placed within the computer, the recording process begins. The laser inside the drive heats the dye to reveal areas that diffuse the light like a traditional CD pit. The CD-R drive does not create pits on the CD; instead the burner creates reflective sections on the CD causing the computer's CD-ROM laser to interpret it as a pit. Once a CD-R disc is finished recording, the CD will be able to be used in any standard CD-ROM, CD-R, CD-RW, or DVD drive. Although, there were issues with the first revision DVD drives reading CD-R discs.

CD-Rs are a low cost solution for backing up software. Each CD-R often only costs a few cents (as of 2010 around 17-cents a disc) and are capable of holding up to 650 MB (74 minutes of music) or 700MB (80 minutes of music). Although these are still a very popular solution for backing up data, more users are turning to USB thumb drives to backup and transfer their data.
