A satellite navigation or sat nav system is a system of satellites that provide autonomous geo-spatial positioning with global coverage. It allows small electronic receivers to determine their location (longitude, latitude, and altitude) to high precision (within a few metres) using time signals transmitted along a line of sight by radio from satellites.

The use of mobile communications equipment for the purpose of worldwide  newscasting. 

A category of software program for process control used to control equipment and conditions. The hardware gathers and feeds data into a computer with SCADA installed. The computer then processes this data and presents it in a .timely manner.

Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It is purely object-oriented functional language and is interoperable with Java and .NET. Scala is equipped with an expressive type system that enforces statically that abstractions are used in a safe and coherent manner.

A 32- and 64-bit microprocessor architecture from Sun Microsystems that is based on Reduced Instruction Set Computing (RISC). SPARC has become a widely-used architecture for hardware used with UNIX-based operating systems.

Scalable Vector Graphics (SVG) is file extension developed by World Wide Web Consortium. SVG file describes images using mathematical equations that enables these two-dimensional images to be displayed in XML pages on the Web. In contrast to JPG and GIF images, which are bitmapped and always remain a specified size, SVG images are scalable to the size of the viewing window and will adjust in size and resolution according to the window in which it is displayed.

A device that captures images from photographic prints, posters, magazine pages, and similar sources for computer editing and display. Scanners come in hand-held, feed-in, and flatbed types and for scanning black-and-white only, or color.

A scanner is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases.

System Center Configuration Manager (earlier called as Systems Management server), SCCM is a software management suite allowing users to manage a large number of Windows computers. SCCM is designed and provided by Microsoft and allows for remote control, patch management, operating system deployment, network protection and other various services.

A software that is designed to carry out repetitive tasks as defined in a schedule based upon calendar and event conditions.

Scratch is a free programming language and an online community where children can program and share interactive media such as stories, games, and animation with people from all over the world. With Scratch, you can program your own interactive stories, games, and animations — and share your creations with others in the online community. Scratch is developed by the Lifelong Kindergarten Group.

The physical surface on which visual information is presented. This surface is usually made of glass. The screen size is measured from one corner to the opposite corner diagonally. 

Screen Capture refers to an act performed by a user to capture/record the visible items on the monitor/computer desktop. The result of the act is a digital image which can be saved on to the computer. There are many free tools available to capture the screen (both browser based and stand-alone applications)

A mockup is a realistic representation of what the product or a website will look like. The final result can look exactly like the mockup, or be a variation of it after version revisions. While some people prefer to draw the mockups using graphic software, others do it straight in HTML/CSS.

A screen protector is an additional sheet of material that can be attached to a screen of an electronic device and protect it against physical damage. Screen protectors first entered the market after the rise of personal digital assistant (PDA) since PDAs were often operated via a stylus.

A programming that translates between legacy application programs and new user interfaces so that the logic and data associated with the legacy programs can continue to be used.
