Terms That you may not know what it refers to !

We Use a lot of terms daily in our life, but have we ever noticed that a lot of these terms we don’t know what it really means or what does it refer to ??


URL: refers to “Uniform Resource Locator“, it is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. URLs occur most commonly to reference web pages (http), but are also used for file transfer (ftp), email (mailto), database access (JDBC), and many other applications.




IP: refers to “Internet Protocol“, and it is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication, An IP address serves two principal functions: host or network interface identification and location addressing.


WWW: refers to “World Wide Web“, and it is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet.



: refers to “Hypertext Transfer Protocol Secure“, is an extension of the Hypertext Transfer Protocol (HTTP) for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted by Transport Layer Security (TLS), or formerly, its predecessor, Secure Sockets Layer (SSL). The protocol is therefore also often referred to as HTTP over TLS, or HTTP over SSL.



HTML: refers to “HyperText Markup Language“, it is the standard markup language for creating web pages and web applications. With Cascading Style Sheets(CSS) and JavaScript, it forms a triad of cornerstone technologies for the World Wide Web.




VPN: refers to “Virtual Private Network“, it extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. VPNs may allow employees to securely access a corporate intranet while located outside the office.



: refers to “Digital Subscribe Line“, it is a family of technologies that are used to transmit digital data over telephone lines. In telecommunications marketing, the term DSL is widely understood to mean “asymmetric digital subscriber line” (ADSL), the most commonly installed DSL technology, for Internet access. DSL service can be delivered simultaneously with wired telephone service on the same telephone line since DSL uses higher frequency bands for data.



GPS: refers to “Global Positioning System“,  a satellite-based radionavigation system. It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.




SMS: refers to “Short Message Service“, is a text messaging service component of most telephone, World Wide Web, and mobile device systems. It uses standardized communication protocols to enable mobile devices to exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines.


: refers to “Graphics Interchange Format“, it is a bitmap image format that supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of up to 256 colors for each frame. These palette limitations make GIF less suitable for reproducing color photographs and other images with color gradients, but it is well-suited for simpler images such as graphics or logos with solid areas of color.

PDF: refers to “Portable Document Format“, it is a file format that presents documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media (including video content) and three dimensional objects.

GPU: refers to “Graphic Processing Unit“, it is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of imagesin a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are very efficient at manipulating computer graphics and image processing, and their highly parallel structure makes them more efficient than general-purpose CPUs for algorithms where the processing of large blocks of data is done in parallel.

: refers to “Digital Video Disc“, it is a digital optical disc storage format invented and developed by Philips and Sony in 1995. The medium can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players. DVDs offer higher storage capacity than compact discs while having the same dimensions.



SD Card: refers to “Secure Digital Card“, it is a non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices. Secure Digital includes four card families available in three different sizes. The four families are the original Standard-Capacity (SDSC), the High-Capacity (SDHC), the eXtended-Capacity (SDXC).


: refers to “Liquid Crystal Display“, it is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images or fixed images with low information content, which can be displayed or hidden, such as preset words, digits.


LED: refers to “Light Emitting Diodes“, it is a two-lead semiconductor light source. When a suitable current is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. LEDs are typically small (less than 1 mm2) and integrated optical components may be used to shape the radiation pattern.
