System File

A file critical to the proper function of an operating system which, if deleted or modified, may cause it to no longer work. Often these files are hidden and cannot be deleted because they are in use by the operating system. A system file is also an attribute that can be added to any file in Widows or DOS using the .sys file extension. Although this process allows the operating system to know the file is important, it does not make the file a system file.

Tip: If you are looking for help about a system file and know its name, try using the search function.

Explode

1. Alternatively referred to as decompress, uncompress, or unpack, explode is the process of taking a compressed file and restoring it back to its original form.

2. Linux command, see the uncompress command page for additional information about this command.

Silicon chip

A silicon chip is an integrated circuit made primarily of silicon; silicon is one of the most common substances used to develop computer chips. The picture shows an example of a silicon wafer with dozens of individual silicon chips.

Steps on how Silicon is formed into chips

1.Silicon is formed into pure silicon crystals using the Czochralski method, which involves using electric arc furnaces to transform raw materials (mostly quartz rock) into metallurgical-grade silicon.

2.To help reduce any impurities the silicon is converted into a liquid, distilled, and then formed back into rods.

3.The rods or poly silicon is then broken up into chunks and placed into a special oven that is purged with Argon gas to eliminate any air. The oven melts the chunks when heated to over 2,500° Fahrenheit.

4.After the chunks have been melted, the molten silicon is spun in a crucible while a small seed crystal is inserted into the molten silicon.

5.While continuing to spin and cool the seed is slowly pulled out of the molten silicon resulting in one large crystal. Often weighing more than several hundred pounds.

6.The large silicon crystal is then tested and x-rayed to make sure it is pure.

7.If the crystal is found to be pure it is cut into thin slices called wafers, like the one shown on this page.

8.After being cut each wafer is buffered to remove any impurities that may have been caused when it was sliced.

9.Once all buffering has been completed the wafer is inserted into a machine that etches the silicon with the circuit design. These designs are etched using a process called photolithography.

10.Photolithography works by first coating the wafer using a photo sensitive chemicals that harden when exposed to UV light and then exposing the wafer to the chip design layer using a UV light.

11.After being exposed the remaining photo sensitive chemicals are washed away leaving only the chip design. Depending on the requirements of that layer after the chemicals are washed away it may be cooked, blasted with ionized plasma, or bathed in metals. Each chip design has multiple layers, so the photolithography steps are repeated several times for each layer until complete.

12.Finally, each silicon chip is sliced from the wafer.

Ink cartridge

Disposable container that contains ink for an inkjet printer. An inkjet printer may only have one ink cartridge that contains only black or each of the primary colors including black. In the image above, is an example of ink cartridges. As can be seen there are four different cartridges, each containing their own color, in this example cyan, magenta, yellow, and black (CMYK).

Jump List

Jump List is a feature introduced in Windows 7. This feature allows you to view recent documents in a program that is pinned to your taskbar. To do this, right-click on any program that has an icon in the taskbar, and it will bring up a list of recently modified documents within that program. The picture is an example of a Jump List in Windows 7.

Emoji

An emoji is an electronic pictograph (picture conveying a message) originally used in Japan, and now all over the world. The word emoji (絵文字) literally translates to "picture character." It is similar to an ASCII emoticon and is frequently a variation on a smiley face; although other forms exist.
Emoji are now part of the Unicode character set, and can be used in e-mails and text messages on iOS or Android devices.

Navigation Pane

Introduced in Microsoft Windows Vista, the Navigation Pane has taken the place of the Places bar. Found on the left side of the Open or Save in Windows, the Navigation Pane lists all of the drives, history, Desktop, and Downloads that used to be on the Places bar. Below is an example of the Windows Navigation Pane.

Pen tablet
A graphics tablet (also digitizer, digital drawing tablet, pen tablet, digital art board) is a computer input device that enables a user to hand-draw images, animations and graphics, with a special pen-like stylus, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. It can also be used to trace an image from a piece of paper which is taped or otherwise secured to the tablet surface. Capturing data in this way, by tracing or entering the corners of linear poly-lines or shapes, is called digitizing.
