An algorithm is a set of instructions designed to perform a specific task. This can be a simple process, such as multiplying two numbers, or a complex operation, such as playing a compressed video file. Search engines use proprietary algorithms to display the most relevant results from their search index for specific queries.
In computer programming, algorithms are often created as functions. These functions serve as small programs that can be referenced by a larger program. For example, an image viewing application may include a library of functions that each use a custom algorithm to render different image file formats. An image editing program may contain algorithms designed to process image data. Examples of image processing algorithms include cropping, resizing, sharpening, blurring, red-eye reduction, and color enhancement.
Adaptive content is digital content that is optimized for multiple devices. It may include text, images, video, and other types of multimedia. The content may simply adapt to your screen size or may appear differently depending on the device on which it is accessed.
An array is a data structure that contains a group of elements. Typically these elements are all of the same data type, such as an integer or string. Arrays are commonly used in computer programs to organize data so that a related set of values can be easily sorted or searched.
If you're like me, you picture a blob as a enigmatic green object that lacks a defined shape or size. In the computer world, however, blobs are a bit easier to define. The term 'blob' actually stands for 'Binary Large Object' and is used for storing information in databases.
A blob is a data type that can store binary data. This is different than most other data types used in databases, such as integers, floating point numbers, characters, and strings, which store letters and numbers. Since blobs can store binary data, they can be used to store images or other multimedia files. For example, a photo album could be stored in a database using a blob data type for the images, and a string data type for the captions.
Because blobs are used to store objects such as images, audio files, and video clips, they often require significantly more space than other data types. The amount of data a blob can store varies depending on the database type, but some databases allow blob sizes of several gigabytes. Now that is a big blob!
