Hi All,

Being a part of computerized world, we all find many basic and sometimes informative computer related terms in our everyday life.This thread is started for collecting all such terms here so that other trades people or even CS/IT people itself can get some benefits from it.

Rules for this thread :

1. Whenever any of the CEan here find time and has some useful term related to computers (anything like related to Hardware, Software, IT, latest technologies, etc..) to share here. Please write it here along with its explanation or definition.

2. Mark the term in BOLD but its explanation or definition should not be in Bold. ok

3. Explanation and definition of the term is must to share ok.

4. If anyone has any images related to it. Please share them also here to make the thread look good. 😉

5. No posts like "Good idea", "Bad idea", "Thanks" ,"Congrats" should be included here ok. If it is so, do add a term also then.😀

6. SMS text as we all know is always banned to use here. 😉

YOTTABYTE

The yottabyte is the largest unit of measurement for computer data.A yottabyte is 2[sup]80[/sup], or 1,208,925,819,614,629,174,706,176 bytes. Its estimated value is 10[sup]24[/sup] or 1,000,000,000,000,000,000,000,000 bytes.

BLU RAY DISC

Blu-ray is an optical disc format such as CD and DVD. It was developed for recording and playing back high-definition (HD) video and for storing large amounts of data. While a CD can hold 700 MB of data and a basic DVD can hold 4.7 GB of data, a single Blu-ray disc can hold up to 25 GB of data.

The name Blu-ray Disc is derived from the blue-violet laser used to read and write this type of disc. Because of its shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. A Blu-ray Disc can store 50 GB,almost six times the capacity of a DVD.

TELEPRESENCE

Telepresence refers to a set of <a href="https://en.wikipedia.org/wiki/Technologies" target="_blank" rel="nofollow noopener noreferrer">Technologies</a> which allow a person to feel as if they
were present, to give the appearance that they were present, or to have an effect, at
a location other than their true location.
It's a new technology by Cisco systems.
Here in this picture, all the people are not in that single room. They are all in different places.

Data Transfer Rate

The speed with which data can be read from a CD ROM drive. 150 kilobytes per second was the original standard rate; 2x = 300 kb/second; 4x = 600kb/s (etc.); 12x = 1.8 mb/s; 16x = 2.4 mb/s.

Animatronics

The art of bringing inanimate objects to life, through use of robotics, puppetry, and aesthetic enhancements. A rare form of robotics; Animatronics began as a dream of Walt Disney in the 50’s, though the idea did not reach fruition until the 1964-65 world fair. The first ride to employ Animatronics was the Pirates of the Caribbean, in 1967. The four main areas connected with Animatronics are: Movies/Television, Theme Parks/ Casinos/ Museums and toys..

Abstract Base Class - A class that does not include an implementation and therefore cannot be directly used. It is used to derive other classes; the derived classes implement the methods.

Active Directory - The database that holds information about component locations, users, groups, passwords, security, and other COM information. Some of this information is currently stored in the Registry, but will eventually (with Windows 2000) be moved to the Active Directory.

ActiveX - An ActiveX component is a COM component that is intended to be portable across more than one platform. Among other things, ActiveX controls can be downloaded from a web server and operate on the client computer outside of the web browser. This is in contrast to a Java applet, which can only operate within the confines of a web browser. ActiveX controls were originally called #-Link-Snipped-# controls before they were modified to work over the internet.

ADO - ActiveX Data Objects. These are COM objects that allow database access.

Apartment - A COM service that provides an execution context for COM objects in such a way as to eliminate the possibility of conflict between #-Link-Snipped-#. There are two kinds of apartments: #-Link-Snipped-#, which contain more than one thread, and #-Link-Snipped-#, which contain only one thread. A process never has more than one MTA, but can have many STAs.

ASP - Active Server Pages. This is an HTML web page that is custom-built in real time. ASP pages can be run as #-Link-Snipped-# objects. You can use VBScript inside ASP pages and IIS will parse the VBScript. An ASP page can load COM-based DLLs. Understanding ASP is the key to designing web-based COM applications. You can use #-Link-Snipped-# to design ASP pages.

Class Factory - Also referred to as a COM class object. It is an object that lives in a server that is responsible for creating the objects registered by that server.

COM - Component Object Model; a specification for writing reusable software components; an infrastructure that allows objects to communicate between processes and computers. All VB objects, including forms and controls, are COM objects. One of the main strengths of COM is that it integrates so many distributed application services in one package.

CORBA - Common Object Request Broker Architecture. This is a distributed object specification that competes with COM.

Deadlock - When two or more transactions conflict in such a way that each is waiting for the other before they proceed. For instance, Transaction A might have a lock on Record 1 while trying to write to Record 2, while Transaction B has a lock on Record 2 while trying to write to Record 1. The two transactions will wait for each other forever unless the deadlock is somehow resolved.

Apache Ivy
It is a powerful dependency manager with transitive dependencies support tool. Mainly used in big and large projects for managing dependencies.

Dependency Manager
Manage the list of a very large no of dependencies in a program without taking tensions of multiple locations stored dependecies. Over all maintain a huge list of dependencies.

Transitive Dependencies
Transitive dependencies are the dependencies of your dependencies in any project.

Grid Computing

Grid Computing (or the use of a computational grid) is applying the resources of many computers in a network to a single problem at the same time - usually to a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data.

Support Vector Machines

A Support Vector Machine (SVM) performs classification by constructing an N-dimensional hyperplane that optimally separates the data into two categories. SVM models are closely related to neural networks. In fact, a SVM model using a sigmoid kernel function is equivalent to a two-layer, perceptron neural network.

The figure below presents an overview of the SVM process.

Adware

Adware is free software that is supported by advertisements. Common adware programs are toolbars that sit on your desktop or work in conjunction with your Web browser. They include features like advanced searching of the Web or your hard drive and better organization of your bookmarks and shortcuts. Adware can also be more advanced programs such as games or utilities. They are free to use, but require you to watch advertisements as long as the programs are open. Since the ads often allow you to click to a Web site, adware typically requires an active Internet connection to run.

Malware

Short for "malicious software," malware refers to software programs designed to damage or do other unwanted actions on a computer system. Common examples of malware include viruses, worms, trojan horses, and spyware.

Mebibyte

A mebibyte is a unit of data storage that equals 2 to the 20th power, or 1,048,576 bytes.

While a megabyte can be estimated as 10^6 or 1,000,000 bytes, a mebibyte is exactly 1,048,576 bytes. This is to avoid the ambiguity associated with the size of megabytes. A mebibyte is 1,024 kibibytes and precedes the gibibyte unit of measurement.

Extending this nice initiative(that was with yottabyte)..

Zettabyte

A zettabyte is 2 to the 70th power, or 1,180,591,620,717,411,303,424 bytes.

It can be estimated as 10 to the 21st power, or 1,000,000,000,000,000,000,000 bytes. A zettabyte is 1,024 exabytes and precedes the yottabyte unit of measurement.

Spoofing in IT :Most common is "email spoofing" i.e making an email mesage appear to have come from one place when really it comes from another. It is generally used by spammers , who do not want their real address to appear on the e-mails they send.
