What is an Algorithm?

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 ... Read more

What is File Compression?

File compression is used to reduce the file size of one or more files. When a file or a group of files is compressed, the resulting "archive" often takes up 50% to 90% less disk space than the original file(s). Common types of file compression include Zip, Gzip, RAR, StuffIt, and 7z compression. Each one of these compression methods uses a unique algorithm to compress the data. So how does a file compression utility actually compress data? While each compression algorithm is different, they all work in a similar fashion. ... Read more

What is Compression?

Compression, or "data compression," is used to reduce the size of one or more files. When a file is compressed, it takes up less disk space than an uncompressed version and can be transferred to other systems more quickly. Therefore, compression is often used to save disk space and reduce the time needed to transfer files over the Internet. There are two primary types of data compression: File CompressionMedia Compression File compression can be used to compress all types of data into a compressed archive. These ... Read more

What is MP3?

Stands for "MPEG Audio Layer-3." MP3 is a compressed audio file format developed by the Moving Picture Experts Group (MPEG). A typical MP3 file sounds similar to the original recording, but requires significantly less disk space. MP3 files are often about one tenth the size of an uncompressed WAVE or AIFF file, which have the same audio quality as a CD. The small file size and high fidelity of MP3 files helped popularize digital music downloads in the late 1990s and early 2000s. Instead of requiring a 40 megabyte download for a single song, the comparable MP3 ... Read more

What is Newsgroup ?

A newsgroup is an online discussion forum accessible through Usenet. Each newsgroup contains discussions about a specific topic, indicated in the newsgroup name. You can browse newsgroups and post or reply to topics using a newsreader program. Access to newsgroups also requires a Usenet subscription. Most Usenet providers offer monthly access for around $10 USD per month. Newsgroups may be either moderated or unmoderated. In a moderated newsgroup, a moderator must approve posts in order for them to become part of the discussion. ... Read more
