Delete is computer terminology for remove or erase. You can delete text from a document of delete entire files or folders from your hard drive. When typing a document, you can remove characters behind the cursor by pressing the delete key. If you want to remove characters in front of the cursor, you can press the smaller delete key near the home and end buttons on the keyboard. You can also remove entire sections of text by selecting the text you wish to delete and pressing either delete button on the keyboard.
Files and folders can be removed from your hard drive by dragging them to the Recycle Bin (Windows) or the Trash (Macintosh) and then emptying the trash. When you delete a file, it is actually not erased, but instead the reference to the file is removed. This means deleted files are still intact until they are written over. Special utilities such as Norton Unerase can recover accidentally deleted files.
CamelCase (also camel case or dromedary case) is a naming convention in which the first letter of each word in a compound word is capitalized. Examples include the video game StarCraft, the band FireHouse, and the company MasterCard. The term CamelCase itself incorporates the CamelCase naming convention. While CamelCase has many applications, in computing, it is most often used in programming languages and website names.
Most programming languages do not allow the use of spaces in the names of functions, variables, or other entities. Therefore, programmers often use CamelCase to define objects within the source code. For example, related variables within a C program might be might have the following lowerCamelCase names: employeeID, employeeFirstName, employeeLastName, and employeeAddress. The capital letters make the names of each variable more readable.
While most programming languages do not require CamelCase, certain programming languages use CamelCase as a standard naming convention. For example, in Java, all classes should be named using UpperCamelCase, while methods and variables should have lowerCamelCase names. The most common alternative to CamelCase is to use underscores (_) to separate lowercase words.
Bootstrap, or bootstrapping, is a verb that comes from the saying, to pull oneself up by his bootstraps. The idiom implies a person is self sufficient, not requiring help from others. Similarly, in the computing world, bootstrapping describes a process that automatically loads and executes commands.
The most fundamental form of bootstrapping is the startup process that takes place when you start up a computer. In fact, the term boot, as in booting up a computer, comes from the word bootstrap. When you turn on or restart a computer, it automatically loads a sequence of commands that initializes the system, checks for hardware, and loads the operating system. This process does not require any user input and is therefore considered a bootstrap process.
While bootstrapping is often associated with the system boot sequence, it can be used by individual applications as well. For example, a program may automatically run a series of commands when opened. These commands may process user settings, check for updates, and load dynamic libraries, such as DLL files. They are considered bootstrap processes because they run automatically as the program is starting up.
Stands for Address Resolution Protocol. ARP is a protocol used for mapping an IP address to a computer connected to a local network LAN. Since each computer has a unique physical address called a MAC address, the ARP converts the IP address to the MAC address. This ensures each computer has a unique network identification.
The Address Resolution Protocol is used when information sent to a network arrives at the gateway, which serves as the entrance point to the network. The gateway uses the ARP to locate the MAC address of the computer based on the IP address the data is being sent to. The ARP typically looks up this information in a table called the ARP cache. If the address is found, the information is relayed to the gateway, which will send the incoming data to the appropriate machine. It may also convert the data to the correct network format if necessary.
If the address is not found, the ARP broadcasts a request packet to other machines on the network to see if the IP address belongs to a machine not listed in the ARP cache. If a valid system is located, the information will be relayed to the gateway and the ARP cache will be updated with the new information. By updating the ARP cache, future requests for that IP address will be much quicker. While this may seem like a complex process, it usually takes only a fraction of a second to complete. If only it was just as easy to find old receipts when you need them.
An animated GIF is a GIF file that includes multiple images or frames. These frames are played back in sequence when the file is opened or displayed in a web browser. The result is an animated clip or a short movie.
The GIF file format includes a Graphics Control Extension (or GCE block), which enables a single GIF file to store multiple frames. This section also specifies the delay between frames, which can be used to set the frame rate or insert pauses at certain points within the animation. Another section, called the Netscape Application Block (NAB), specifies how many times the animation will repeat (a setting of 0 is used for infinite repetitions).
In the early years of the Web, animated GIFs were a popular way to display motion and liven up websites. They were commonly used for advertisements, such as banners and leaderboards. As Flash animations became more popular, animated GIFs became less prominent. However, animated GIFs have recently seen a resurgence on the web since they are supported by all platforms. For example, Apples iOS does not support Flash animations, but can display animated GIFs.
Several image editing programs, such as Adobe Photoshop and GIMP, can be used to create animated GIFs. Other graphics programs can merge multiple image files into a single GIF. Some video utilities can even convert short videos to animated GIFs. While this can be useful for sharing small videos on the web, the GIF format is not as efficient as the MPEG format for storing videos longer than a few seconds.
