PS/2 is a type of port used by older computers for connecting input devices such as keyboards and mice. The port was introduced with IBMs Personal System/2 computer in 1987 (which was abbreviated PS/2). In the following years, the PS/2 port became the standard connection for keyboards and mice in all IBM compatible computers.
The PS/2 port has six pins and is roughly circular in shape. Since each PS/2 port is designed to accept a specific input, the keyboard and mouse connections are typically color-coded. For example, the keyboard port on the back of the computer is often purple, while the mouse port is usually green. Similarly, the connector on the end of the keyboard cord is purple and the mouse cord connector is green. This makes it easy for all users to know where to plug the cables into the computer. The concept is similar to the color-coded composite audio/video connections on the back of a TV, which use red, white, and yellow connectors.
While the PS/2 port enjoyed a good run for almost two decades, now most keyboards and mice use USB connectors. Unlike PS/2 ports, USB devices can be plugged into any USB port or even a USB hub and the computer will automatically determine what the device is. USB is also hot swappable, meaning the connections can be removed while the computer is running. If you remove a PS/2 device while the computer is on, it may potentially cause damage to the hardware. Therefore, if you are using a PS/2 device, it is best to turn off the computer before connecting or unplugging a keyboard or mouse.
NOTE: The term PS2 is also a common abbreviation for Sonys PlayStation 2 game console.

When computers communicate with each other, there needs to be a common set of rules and instructions that each computer follows. A specific set of communication rules is called a protocol. Because of the many ways computers can communicate with each other, there are many different protocols -- too many for the average person to remember. Some examples of these different protocols include PPP, TCP/IP, SLIP, HTTP, and FTP. Can you guess what the last P in each acronym stands for? If you guessed protocol, send yourself a congratulations e-mail.

Stands for Personal Information Manager. A PIM is a software application that serves as a planner, notebook, and address book all in one. It can also include things like a calculator, clock , and photo album. PIMs are especially popular for PDAs (Personal Digital Assistants), since this is why most people have them. However, for those of us who dont have all the latest portable gadgets, PIM programs are also developed for desktop computers.

A mouse pad, or mousing surface, is a surface designed for tracking the motion of a computer mouse. Early mouse pads were literally pads, which had soft surfaces. The slight cushion allowed the mouse ball to roll smoothly in any direction. Modern mouse pads typically have harder surfaces, designed to track the motion of optical mice.
Mouse pads come in many shapes and sizes. Most are rectangular, though are some are circular or oval shaped. While the majority of mouse pads are less than a foot wide or long, graphic artists and CAD designers sometimes use mouse pads that are much larger. These super-sized mousing surfaces allow them to use a slow, precise mouse speed without needing to lift up the mouse very often. Computer gamers also prefer larger mouse pads, because they offer more desktop real estate for making long, fast motions.
Since optical mice track motion by detecting small changes in the surface below the mouse, the mouse pads surface affects how accurately the mouse responds to movement. Lighter colored mouse pads typically produce the best results since they reflect the most light. Some highly reflective mouse pads even claim to have battery saving capabilities for wireless mice. The improvement in battery life most likely comes from how quickly the mouse enters low-power mode when it stops moving.
Since optical mice work on just about any opaque surface, you typically do not even need a mouse pad to use a mouse. However, a good mouse pad can provide smooth, accurate motion, which is beneficial if cursor accuracy is important for your work. When choosing a mouse pad, make sure you get one large enough for your needs, but not so large that it wont fit on your desk. If possible, choose a mouse pad with a built-in wrist rest or buy a separate wrist rest if necessary. This small ergonomic addition will relieve a lot of strain on your wrist no matter what mouse pad you use.

Lag is a slow response from a computer. It can be used to describe any computer that is responding slower than expected. However, the term is most commonly used in online gaming.
Video game lag is generally caused by one of two factors – 1) a slow computer or 2) a slow Internet connection. If you are playing an online multiplayer game and your computer cannot process the incoming data in real-time, it may slow the game down for everyone. If your Internet connection is slow or inconsistent (which is common with a shared wireless connection), your system may not send and receive enough data to keep up with other players. This lag may produce choppy frame rates and cause a delay between your input and what happens on the screen.
In an ideal world, all online gamers would have fast computers and fast Internet connections. The reality, however, is that players have a variety of computer systems and significantly different Internet connection speeds. Therefore, video game developers must account for lag in multiplayer games. The preferred method is to make sure lag only affects the individual with the slow computer or Internet connection. This prevents players with high-quality gaming setups from being negatively affected by users with slow systems.
In some cases, a player with a high amount of lag will be booted from a multiplayer game. For example, in StarCraft 2, if a players system is not responding, a message will appear on the players screen that says, Waiting for Server. Other players in the game will see a message that says Waiting for player: [player name]. If the lag is too high, the player will eventually be booted from the game.
NOTE: Lag can also be used as a verb. For example, a player that is lagging may be slowing down the game.

Stands for Joint Photographic Experts Group. JPEG is a popular image file format. It is commonly used by digital cameras to store photos since it supports 224 or 16,777,216 colors. The format also supports varying levels of compression, which makes it ideal for web graphics.
The 16 million possible colors in a JPEG image are produced by using 8 bits for each color (red, green, and blue) in the RGB color space. This provides 28 or 256 values for each of the three colors, which combined allow for 256 x 256 x 256 or 16,777,216 colors. Three values of 0 produce pure black, while three values of 255 create pure white.
The JPEG compression algorithm may reduce the file size of a bitmap (BMP) image by ten times with almost no degradation in quality. Still, the compression algorithm is lossy, meaning some image quality is lost during the compression process. For this reason, professional digital photographers often choose to capture images in a raw format so they can edit their photos in the highest quality possible. They typically export the pictures as JPEG (.JPG) images when they are shared or published on the web.
Besides image data, JPEG files may also include metadata that describes the contents of the file. This includes the image dimensions, color space, and color profile information, as well as EXIF data. The EXIF data is often stamped on the image by a digital camera and may include the aperture setting, shutter speed, focal length, flash on/off, ISO number, and dozens of other values.
While the JPEG format is great for storing digital photos, it does have some drawbacks. For example, the lossy compression can cause an issue called artifacting, in which parts of the image become noticeably blocky. This typically happens when a high compression setting is used to save the image. For saving small images and images with a lot of text, the GIF format is often a better alternative. JPEG images also dont support transparency. Therefore, the JPEG format is a poor choice for saving non-rectangular images, especially if they will be published on webpages with different background colors. The PNG format, which supports transparent pixels is more ideal for these types of images.
NOTE: The Joint Photographic Experts Group, which the JPEG image format is named after, published the first JPEG specification in 1992. Since then, the organization has developed several variations of the format, including JPEG 2000 and JPEG XR. However, the standard JPEG format remains the most popular.
File extensions: .JPG, .JPEG, .JFIF, .JPX, .JP2

An integrated circuit, or IC, is small chip that can function as an amplifier, oscillator, timer, microprocessor, or even computer memory. An IC is a small wafer, usually made of silicon, that can hold anywhere from hundreds to millions of transistors, resistors, and capacitors. These extremely small electronics can perform calculations and store data using either digital or analog technology.
Digital ICs use logic gates, which work only with values of ones and zeros. A low signal sent to to a component on a digital IC will result in a value of 0, while a high signal creates a value of 1. Digital ICs are the kind you will usually find in computers, networking equipment, and most consumer electronics.
Analog, or linear ICs work with continuous values. This means a component on a linear IC can take a value of any kind and output another value. The term linear is used since the output value is a linear function of the input. For example, a component on a linear IC may multiple an incoming value by a factor of 2.5 and output the result. Linear ICs are typically used in audio and radio frequency amplification.

A hard copy is a printed document. It may be a text file, photograph, drawing, or any other type of printable file. For example, instead of e-mailing a business memo, it may be sent out as a hard copy, or an actual physical paper containing the memo.
When a document is created on a computer, it is typically saved as a file on the the computers hard drive. This is sometimes referred to as a soft copy. While the file can be easily opened and edited on a computer, it can also be easily deleted. Therefore, sometimes printing a hard copy is done to create a physical backup of the document.

Frequency measures the number of times something occurs in a specific amount of time. For example, if someone visits the grocery store twice a week, her shopping frequency is 2 visits per week. While frequency can be used to measure the rate of any action, in technical applications it is typically used to measure wave rates or processing speed. These frequencies often occur multiple times per second and therefore are measured in hertz (Hz) or related units of measurement, such as megahertz or gigahertz.
Frequency can be used to measure the rate of waves, such as sound waves, radio waves, and light waves. Audible sound waves have a frequency of roughly 20 Hz to 20,000 Hz (20 kilohertz). Therefore, the sounds you hear have waves that occur anywhere from 20 to 20,000 times per second. Lower frequencies produce low-pitched sounds and are called bass frequencies. Higher frequencies produce high-pitched sounds and are called treble frequencies.
Sound waves are compression waves, which actually move small amounts of air particles. Other waves, such as radio waves and light waves do not require air particles to travel. These waves are part of the electromagnetic spectrum and generally have much higher frequencies than sound waves. For example, most radio waves are measured in megahertz (1,000,000 hertz) or gigahertz (1,000,000,000 hertz). Visible light has a frequency of about 400 terahertz to 780 terahertz.
In the computer world, frequency is often used to measure processing speed. For example, clock speed, measures how many cycles a processor can complete in one second. If a computer has a 3.2GHz processor, it can can complete 3,200,000,000 cycles per second. FLOPS, which is used to measure floating point performance, is also a frequency-based calculation (operations per second). Finally, computing speed may also be defined in MIPS, which measures instructions per second.

scape Noun. A scape is someone who is very stingy and ungenerous with their weed but will be more than happy to pack the fattest bowl or roll the fattest joint of someone elses weed. can be used for people who are stingy with anything. e.g. money, food, cigarettes, ect. They are also very sneaky will try to steal anything, even from their friends.

Stands for Digital Versatile Disc Recordable. A DVD-R looks the same as a regular DVD, but like a CD-R, it can be used to record data. Once a DVD-R has been burned, or written to, it cannot be written to again. A basic single-sided, single-layer DVD-R disc can store 4.7GB of data. Double-layer discs can store 8.5GB, while double-sided DVD-Rs can store 9.4GB.
DVD-R is the most common format of writable DVDs (compared to the DVD R and DVD-RAM formats). Most DVD players and DVD-ROM drives can read DVD-R discs. That means you can use a DVD-R disc to back up several gigabytes of data on your computer or make your own video DVD. The Apple SuperDrive used in many Macintosh computers supports the DVD-R format.

Stands for Digital Video. Unlike traditional analog video, which is captured frame by frame on a tape, digital video is recorded digitally, as ones and zeros. Since it is stored in a digital format, digital video can be recognized and edited by a computer, which is also a digital device.
DV camcorders, including Mini DV and HDV, record digital video and therefore can export the footage to a computer using a Firewire (IEEE 1394) cable. Analog camcorders such as SVHS and Hi-8 devices must be run through a analog to digital converter (DAC) in order to be transferred to a computer.

A docking station, or dock, is a device that connects a laptop to multiple peripherals. It provides a single connection point that allows a laptop to use a connected monitor, printer, keyboard, and mouse. This allows a laptop to function like a desktop computer.
Laptop manufacturers often build custom docking stations for their laptops. These docks usually have a proprietary input port that connects to a matching port on specific laptop models. Early docks, such as those built in the 1990s, included serial ports for connecting input devices, parallel ports for connecting printers and scanners, and VGA ports for connecting monitors. In recent years, laptop docking stations have become more standardized, with USB ports for connecting most peripherals and DVI ports for connecting displays.
While modern docks provide standardized I/O ports, many docking stations still use a proprietary dock connector, which means when you buy a new laptop, you may need to buy a new dock. Fortunately, the Thunderbolt connector, first used in Apples MacBook laptops, eliminates the need for a docking station. A single Thunderbolt connection can support USB, FireWire, Ethernet, and DisplayPort connections. Therefore, a Thunderbolt hub serves the same purpose as a laptop dock and is compatible with any computer that has a standard Thunderbolt connection.
NOTE: Docking stations may also refer to hardware used to connect tablets, smartphones, and other portable devices to one or more peripherals. However, these devices are generally called docks and typically have fewer I/O connections than a laptop dock.

Hoggy, basically meaning a hogger, hoarder, stealer, theif, nasty person or generally quite a bit more selfcentred than the average selfcentred person.
Have the ability to hog/steal your closest friends and family, snaking their way in and then making every attempt at blackening your name so a rift appears and your friends and family do not want to associate with you...untill, indeed the hoggy loses interest or the people she has hogged are no longer uselfull and then she turns on them and makes them feel very uncomfortable by spreading roumers, destroying private property and generally being an asshole.
A hoggy also likes to keep their partner on a tight rope and doesnt like them to do or say anything without prior agreement from them. They vet what they wear and how they have their hair cut and even the music they listen to. The partner of the hoggy may even only be alowed in social situations if accompanied by another member of the hoggies family.
Trieds regularly to sleep with other peoples partners just to get to them.
Thinks theyare a lot hotter than they really are
Generally a not very nice person.

A column is a vertical group of values within a table. It contains values from a single field in multiple rows.

In databases, columns may be defined as individual fields within a table. Each field has a name, such as Name, Address, or Phone Number. Therefore, when multiple values from a column are selected, they will all have similar information, such as a list of phone numbers. When defining columns in databases and spreadsheets, it is often possible to specify the type of data, such as a string, number, or date. This helps ensure all the data within a given column has a similar format.

NOTE: While it is easy to get rows and columns confused, just remember that columns are vertical (like the columns used in architecture), while rows are horizontal, like rows of text.
