When a program on your computer has an error, you may see a message pop up on the screen saying, Illegal Operation. This is a rather tactless way of saying something went wrong with the program that was running. It could also be a fault with the operating system itself. The problem with the phrase Illegal Operation is that it seems to put the blame on you, the user. The fact is, the error was most likely caused by a bug in the program, and is certainly not your fault.
Common errors that produce illegal operation messages are divide by zero errors (no number is divisible by zero), and memory leaks where the program tries to address memory in another programs memory space. If these errors happen while a program is running, the execution comes to an abrupt halt and the program usually quits. Illegal operations can happen on both Windows and Macintosh computers, though the Mac OS X operating system is better at avoiding system-level errors.
A hostname is a label that identifies a hardware device, or host, on a network. Hostnames are used in both local networks (LANs) as well as wide area networks like the Internet.
Local network hostnames dont have a standard format, but they cannot contain spaces and other special characters like commas, periods, and apostrophes. For example, if your name your Mac, Mikes iMac, the hostname will automatically be translated to Mikes-iMac.local. If youre a Mac user, you can customize your computers hostname by modifying the computer name in the Sharing System Preference. If you use a Windows PC, you can modify your hostname by changing the computer name within the System Control Panel.
Internet hostnames are simply domain names, like techterms.com. They are typically fully qualified domain names, such as www.techterms.com or ftp.techterms.com, since each subdomain is a different hostname. However, if a website URL does not include a domain prefix like www, then the domain name itself (e.g. techterms.com) can serve as the hostname.
In both local networks and wide area networks like the Internet, hostnames are translated to IP addresses using DNS. Either a local or remote DNS server maps each hostname to a unique IP address, which is how the device is actually identified on a network. Therefore, hostnames are simply used as human-readable labels, which makes it easy to remember names of devices on a network and websites on the Internet.

A font is a specific typeface of a certain size and style. For example, one font may be Arial 12 pt bold, while another font may be Times New Roman 14 pt italic. Most word processing programs have a Font menu that allows you to choose the typeface, size, and style of the text. In order to use a font, you must have it installed on your computer. Windows provides access to fonts using the Fonts control panel. The Mac OS stores fonts in a Fonts folder and includes a separate Font Book application for managing fonts.
Most people have several thousand files on their computers hard disk, so imagine how hard it would be to find anything if the files were not organized. Fortunately, all hard disks use a file system, which organizes all the files on the disk. The file system is created when you initialize or format your hard disk. It sets up the root directory and subsequent directories beneath it. The file system allows you to create new files and folders, which are added to different parts of the file tree on your hard disk.
For example, your hard disk probably has separate folders for programs, documents, pictures, music, and movie files. Within these folders, there are likely other folders that futher organize your files. All these folders (or directories) are organized by your computers file system. There are also several folders your computers operating system uses to store system files, such as startup data and system preferences. Some of these folders are invisible to the user, but are recognized by the computers file system.
Older Windows machines used a file system called FAT32, while newer Windows computers use NTFS. Macintosh computers used the HFS file system for a long time, but now use an updated version of HFS, called HFS . Though you typically dont need to know all the details of your computers file system, it is nice to know that it is always working to keep your files organized.
The Escape key is located in the upper-left corner of a computer keyboard. It typically resides to the left of the Function keys (F1, F2, F3, etc.) and above the tilde (~) key. Most often, is is labeled with the abbreviation esc.
The Escape key has many purposes, which have evolved over time. Most uses share the common action of exiting or escaping an operation. The Escape key is often used to quit, cancel, or abort a process that is running on a computer.
Some specific examples of Escape key functions include:
While most applications dont require the use of the Escape (esc) key, it can be a handy shortcut for stopping or canceling operations on your computer.

Stands for Error Correction Code. ECC is used to verify data transmissions by locating and correcting transmission errors. It is commonly used by RAM chips that include forward error correction (FEC), which ensures all the data being sent to and from the RAM is transmitted correctly.
ECC RAM or memory is similar to parity RAM, which includes a parity bit that validates the data being sent. The parity bit is a redundant binary value of 1 or 0 that is sent along with the data. If the parity bit does not match the value of the data it represents, it indicates an error in the transmission and the data may need to be resent. ECC works in a similar way, but uses a more advanced error correction system that can correct data transmission errors on the fly.
Since ECC memory requires more processing, it can be slower than non-ECC RAM and basic parity RAM. However, ECC RAM provides more reliable data transfers, which results is greater system stability. Therefore, high-end servers and workstations may use ECC memory to minimize crashes and system downtime.
The Dvorak keyboard is a keyboard layout named after its designer, Dr. August Dvorak. He designed the keyboard as alternative to the standard QWERTY keyboard layout, with the goal of improving typing ergonomics.
Dvorak developed the new keyboard layout after studying common typing patterns. He determined the QWERTY layout, which was designed for telegraph operators and early typewriters, was inefficient. It required awkward motions, didnt use the home row (ASDF) enough, and required many common key patterns to be typed with one hand.
To improve typing efficiency, Dvorak designed his keyboard layout to alternate keystrokes between left and right hands. He also placed the most common letters in the home row. For example, since nearly all words have vowels, the home row on the Dvorak keyboard begins with the letters AOEUI. The vowel keys are placed next to each other since vowels often alternate with consonants.
Dvorak patented his keyboard layout in 1936, claiming layout offered the faster typing speeds, greater accuracy, and less fatigue than the QWERTY keyboard. Despite these benefits, the Dvorak keyboard has never achieved the popularity of the QWERTY layout. Most people still learn to type on a QWERTY keyboard and simply do not want to relearn a new keyboard layout. Therefore, nearly all desktop computers and laptops sold in Western countries come with QWERTY keyboards.
NOTE: The original version of the Dvorak keyboard is also known as the Dvorak Simplified Keyboard (DSK). In 1982, ANSI standardized a slight variation of the Dvorak keyboard layout, called the American Simplified Keyboard (ASK).
