Networking
A computer network, or simply a network, is a collection of computers and other hardware components interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network. Simply, more than one computer interconnected through a communication medium for information interchange is called a computer network.
Networks may be classified according to a wide variety of characteristics, such as the medium used to transport the data, communications protocol used, scale, topology, benefit, and organizational scope.
Communications protocols define the rules and data formats for exchanging information in a computer network, and provide the basis for network programming. Well-known communications protocols include two Ethernet, a hardware and link layer standard that is ubiquitous in local area networks, and the Internet protocol suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.
Computer networking is sometimes considered a sub-discipline of electrical engineering, telecommunications, computer science, information technology or computer engineering, since it relies upon the theoretical and practical application of these disciplines.
Web Design
Web design is a broad term covering many different skills and disciplines that are used in the production and maintenance of websites. The different areas of web design include; web graphic design, interface design, authoring; including standardised code and proprietary software, user experience design and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. The term web design is normally used to describe the design process relating to the front-end (client side) design of a website including writing mark up, but this is a grey area as this is also covered by web development. Web designers are expected to have an awareness of usability and if their role involves creating mark up then they are also expected to be up to date with web accessibility guidelines.
Graphic Design
Graphic design is a creative process—most often involving a client and a designer and usually completed in conjunction with producers of form (i.e., printers, signmakers, etc.)—undertaken in order to convey a specific message (or messages) to a targeted audience. The term "graphic design" can also refer to a number of artistic and professional disciplines that focus on visual communication and presentation. The field as a whole is also often referred to as Visual Communication or Communication Design. Various methods are used to create and combine words, symbols, and images to create a visual representation of ideas and messages. A graphic designer may use a combination of typography, visual arts and page layout techniques to produce the final result. Graphic design often refers to both the process (designing) by which the communication is created and the products (designs) which are generated.

Home Theatre
A home theater or home theatre is a theater built in a home, designed to mimic (or exceed) commercial theater performance and feeling, more commonly known as a home cinema. Today, home cinema implies a real "cinema experience" at a private home. At Global Technology we use home automation with our theatre to bring that whole, rich vibe to your theatre. Home cinema, commonly referred to as home theater or home theatre, are home entertainment set-ups that seek to reproduce movie theater video and audio feeling in a private home. And guess what! Best of all now we have complete wireless optical wiring so you can watch tv with none of those tabgles in your tv wall/base.
Telecommunication
Telecommunication is the science and practice of transmitting information by electromagnetic means.
Communication is talking to someone or thing not necessarily through technological means. Telecommunication, however, is talking through technology meaning phones, Internet, radio etc...
In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages such as coded drumbeats, lung-blown horns, and loud whistles.
In modern times, telecommunications involves the use of electrical devices such as the telegraph, telephone, and teleprinter, as well as the use of radio and microwave communications, as well as fiber optics and their associated electronics, plus the use of the orbiting satellites and the Internet.
Digital Cabling
Digital cable is a generic term for any type of cable television distribution using digital video compression or distribution. The technology was originally developed by Motorola.[1] Cable companies converted to digital systems during the last decade, when television signals were converted to the digital HDTV format, which was not compatible with earlier analog cable systems. In addition to providing higher resolution HD video, digital cable systems provide expanded services such as pay-per-view programming, cable internet access and cable telephone services. Digital cable signals are encrypted, which reduced the high incidence of cable theft which occurred in analog systems.
CCTV Cameras Systems
Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. Videotelephony is seldom called "CCTV" but the use of video in distance education, where it is an important tool, is often so called. And using these as systems brings a whole new topic.
Home Automation
Home automation (also called domotics) is the residential extension of "building automation". It is automation of the home, housework or household activity. Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, and other systems, to provide improved convenience, comfort, energy efficiency and security. Home automation for the elderly and disabled can provide increased quality of life for persons who might otherwise require caregivers or institutional care.
The popularity of home automation has been increasing greatly in recent years due to much higher affordability and simplicity though smartphone and tablet connectivity. The concept of the "Internet of Things" has tied in closely with the popularization of home automation.
Photography
Photography is the art, science and practice of creating durable images by recording light or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of an image sensor.[1] Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. The result in an electronic image sensor is an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing.
Broadband
The term broadband refers to the wide bandwidth characteristics of a transmission medium and its ability to transport multiple signals and traffic types simultaneously. The medium can be coax, optical fiber, twisted pair or wireless. In contrast, baseband, describes a communication system in which information is transported across a single channel.
Prior to the invention of home broadband, dial-up Internet access was the only means by which one could access the Internet and download files such as songs, movies, e-mails, etc. It would take anywhere from 10–30 minutes to download one song (3.5 MB) and over 28 hours to download a movie (700 MB). Dial-up Internet was also considered very inconvenient as it would impair the use of the home telephone line, and users would contemplate whether or not to get a second line, and if doing so was worth the cost.
In 1997, the cable modem was introduced, although the common use of broadband didn't begin rising until 2001. Having a broadband connection enabled one to download significantly faster than on dial-up. As with many new technologies, most consumers were unable to afford the cost of faster Internet service. However, high costs weren't a factor for long as by 2004, most average American households considered home broadband service to be affordable. Since its inception, broadband has continually strengthened and available connection speeds continue to rise.
Telephone Installation
The telephone, colloquially referred to as a phone, is a telecommunications device that transmits and receives sounds, usually the human voice. Telephones are a point-to-point communication system whose most basic function is to allow two people separated by large distances to talk to each other. Developed in the mid-1870s by Alexander Graham Bell and others, the telephone has long been considered indispensable to businesses, households and governments, is now one of the most common appliances in the developed world. The word "telephone" has been adapted to many languages and is now recognized around the world. Referring to actual service, telephone installation is the process of installing the telephone or telephone internet.
Computer Services and Maintenance
A computer is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU) and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved. Again, referring to the actual service we provide repairs and maintenance fro these computers or computerized systems.
Project Management
Project management is the discipline of planning, organizing, securing, managing, leading, and controlling resources to achieve specific goals. A project is a temporary endeavor with a defined beginning and end (usually time-constrained, and often constrained by funding or deliverables), undertaken to meet unique goals and objectives, typically to bring about beneficial change or added value. The temporary nature of projects stands in contrast with business as usual (or operations), which are repetitive, permanent, or semi-permanent functional activities to produce products or services. In practice, the management of these two systems is often quite different, and as such requires the development of distinct technical skills and management strategies.
Communications Cabling
A cable is most often two or more wires running side by side and bonded, twisted or braided together to form a single assembly, but can also refer to a heavy strong rope. In mechanics cables, otherwise known as wire ropes, are used for lifting, hauling and towing or conveying force through tension. In electrical engineering cables are used to carry electric currents. An optical cable contains one or more optical fibers in a protective jacket that supports the fibers. With communications cabling, this can be the data, information, anything transferring from one to another.
Security Systems
Security is the degree of protection to safeguard a nation, union of nations, persons or person against danger, damage, loss, and crime. Security as a form of protection are structures and processes that provide or improve security as a condition. The Institute for Security and Open Methodologies (ISECOM) in the OSSTMM 3 defines security as "a form of protection where a separation is created between the assets and the threat". This includes but is not limited to the elimination of either the asset or the threat. Security systems can also involve CCTV Ccamera systems.
Wireless Systems
NWireless telecommunications refers to the transfer of information between two or more points that are not physically connected. Distances can be short, such as a few metres for television remote control, or as far as thousands or even millions of kilometres for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones.
