Définition ANSI ( American National Standart Institute )

Stands for "American National Standards Institute." ANSI is a non-profit organization based in the United States that works to develop and promote standards in the United States and around the world. By standardizing new products and technologies, both ANSI strengthens the US position on the world market and helps ensure the integrity and safety of...

Définition ARP ( Address Resolution Protocol )

Stands for "Address Resolution Protocol". ARP is a protocol used to map an IP address to a computer connected to a LAN. Since each computer has a unique physical address called MAC address, ARP translates IP address to the MAC address. This ensures that each computer has a unique network identification.The Address Resolution Protocol is used when...

Définition ASCII

Stands for "ASCII." ASCII character encoding provides a standard way to represent characters by using numeric codes. These include uppercase English letters and lowercase letters, numbers and punctuation symbols.ASCII uses 7 bits to represent each character. For example, a capital "T" is represented by the number 84 and a lower case "t" is represented...

Définition Biometrics

Biometrics refers to technologies used to detect and recognize human physical characteristics. In the world of computing, biometrics is often synonymous with "biometric authentication", a type of security clearance based on the biometric input.There are several types of biometric authentication. Common examples include the scanning of fingerprints,...

Définition Boot Sector

The boot sector is a dedicated hard drive or other storage device containing the data used to start a computer system section. It includes the Master Boot Record (MBR), which is accessible during the boot sequence.The boot sector is usually located at the beginning of a disc before the first partition. It includes the separation plan, which identifies...

Définition Boot Sequence

Whenever a computer starts up, it goes through a series of processes first. This sequence of events is called a "boot sequence." During the startup sequence, the computer activates the necessary hardware and loads the appropriate software so that the user can interact with the machine.The boot sequence begins with access to the BIOS of the computer...

Definition Cache

Cache, pronounced "cash" (not "catch" or "cashay") stores recently used the information to make it readily available at a later date. Computers integrate several types of caching to run more effectively, thereby improving performance. common types of caches include browser cache, disk cache, cache, and processor cache. 1. Browser Cache - Most data...

Definition CDMA

Stands for "Code Division Multiple Access." CDMA is a wireless transmission technology that was developed during World War II by English allies to avoid having their scrambled transmissions. After the war, Qualcomm patented technology and commercially available as a digital cellular technology. Now CDMA is a popular method of communication used by...

Definition Clean Room

A simple definition of what would be "the opposite of my room." But technically speaking, a clean room is a highly purified and regulated room for the production of sensitive equipment contamination. For example, the production of microprocessors is in a clean room, since smaller amounts of dust can create defects in production. therefore, the air...

Definition Clock Cycle

One clock cycle, or simply a "cycle" is an electronic pulse of a single processor. During each cycle, a processor can perform a basic operation such as retrieving an instruction, access to memory or writing data. Since simple commands can be performed at each cycle, the majority of CPU processes require several clock cycles. In physics, the frequency...

Definition Alpha Software

Alpha software is software that is still in the phase of early detection. It's functional enough to be used, but it is dull and often lack many features that will be included in the final version of the program. The "alpha phase" of software development follows the steps of programming and design at first, but before the "beta" in which the software...

Definition Zebibyte

Zebibyte is a storage unit data which is equal to 2 to the power 70, or 1,180,591,620,717,411,303,424 bytes.While a zettabyte can be estimated as 10 ^ 21 bytes or 1,000,000,000,000,000,000,000 a zebibyte exactly 1,180,591,620,717,411,303,424 bytes. This avoids the ambiguity associated with the size of zettabytes. Is a zebibyte exbibytes 1024 precedes...

Definition Unicode

Unicode is an encoding standard universal character. It defines how individual characters are represented in text files, web pages, and other document types.Unlike ASCII, which was designed to represent only basic English characters, Unicode has been designed to support characters of all languages of the world. The standard ASCII character set supports...

Definition Petaflops

Petaflop is a unit of measurement used to measure the performance of floating point unit, or FPU Processor. It can also be written as "petaFLOPS" or "PFLOPS." Since FLOPS stands for "Floating Point Operations Per Second", the term "petaflops" can be either singular (one petaflop) or multiple (two or more petaflops.) A petaflop is equal to 1,000 teraflops,...

Assembler Definition

An assembler program which is converted into machine code in assembler language. It takes the controls and basic operations of assembly code and converts into a binary code that can be recognized by a specific processor type.Assemblers are similar in that they compilers to produce executable code. However, the most simplistic assemblers because they...

Assembly Language Definition

An assembly language is a language for low-level programming designed for a specific type of processor. It can be produced by compiling the source code of a programming language of high level (such as C / C ++), but can also be written from scratch. Assembly code can be converted to machine code using an assembler.Like most compilers convert source...

Command Line Interface Definition

Line interface (CLI or) is a text-based interface used for entering commands. In the early days of computing, before the mouse, it has been the standard method for interacting with a computer. While the graphical user interface (GUI) has largely replaced CLI, they are still included with many operating systems such as Windows and OS X.There are many...

Bash Definiton

Bash, but generally are not capitalized, is an acronym for "Bourne-Again Shell" and is named after Stephen Bourne, the creator of the Unix shell "sh". It is a command language interpreter derived from sh can execute commands entered on input speed control and process text file.Bash (bash) supports all commands of the original Bourne shell (sh), and...

Root

In the computer world, "root" refers to the top-level directory of a file system. The word is derived from a root of the tree, as it represents the development of a hierarchical tree structure starting. The records of the tree represent the branches, while the actual files are considered the leaves. However, unlike a true tree of life, a tree data...

DMZ "Demilitarized Zone"

Means "demilitarized zone." In computing, a DMZ is a section of a network between the intranet and a public network such as the Internet. It may contain a number of computer systems or single host.The purpose of a DMZ is to protect an intranet from external access. By separating the intranet from hosts that can be accessed outside of a local area...

OLED "Oragnic Light Emitting Diode"

Stands for "Organic Light Emitting Diode" and is pronounced "oh-led." OLED is a type of flat panel display similar to a screen that does not require a backlight. Instead, each LED in a panel OLED lights individually.OLED screen has six layers that work together to produce color images. These layers include the following, from bottom to top: ...
