The Saudi Telecommunication Group provides integrated mobile, fixed and broadband communications services to over 160 million customers globally. The company is Headquartered in Riyadh, Saudi Arabia. Saudi Telecom Company (STC) is the largest telecommunications company by market capitalization, total revenue and number of employees in the Arab State region. In the last few years, STC has moved beyond its domestic borders into the international markets, forming a network of businesses and investments in a number of GCC countries, Asia and Africa. The company is now present in Kuwait, India, Indonesia, Malaysia, Turkey, South Africa and Bahrain, enabling STC to serve a greater number of customers internationally.[3]
Services
STC services are divided into three broad categories: Jawal Al Amani Al Aaliyah (mobile network), Home (landlinenetwork), and Enterprise services.[4]
Company Services
Landline - A landline telephone (also known as land line, land-line, main line, home phone, landline, fixed-line, and wireline) refers to a phone that uses a metal wire telephone line for transmission as distinguished from a mobile cellular line, which uses radio waves for transmission.
In 2003, the CIA reported approximately 1.263 billion main telephone lines worldwide. China had more than any other country at 350 million and the United States was second with 268 million. The United Kingdom has 23.7 million residential fixed homephones.[1][unreliable source?] The 2013 statistics show that the total number of fixed-telephone subscribers in the world was about 1.16 billion, which is an all time low.[2] The number of landline subscribers continuously decreases due to upgrades in digital technology and the conveniences that come with switching to wireless (cellular) or Internet-based alternatives.
Mobile Mobile computing is human–computer interaction by which a computer is expected to be transported during normal usage. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc and infrastructure networks as well as communication properties, protocols, data formats and concrete technologies. Hardware includesmobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications.
Internet Services The Internet protocol suite is the computer networking model and set of communications protocols used on theInternet and similar computer networks. It is commonly known as TCP/IP, because among many protocols, theTransmission Control Protocol (TCP) and the Internet Protocol (IP) is the accepted and most widely used protocol inInternet. Often also called the Internet model, it was originally also known as the DoD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense.
TCP/IP provides end-to-end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.[1][2] From lowest to highest, the layers are the link layer, containing communication technologies for a single network segment (link); the internet layer, connecting hosts across independent networks, thus establishing internetworking; the transport layer handling host-to-host communication; and the application layer, which provides process-to-process application data exchange.
Television Services A television, commonly referred to as TV, telly or the tube, is a telecommunication medium used for transmitting sound with moving images in monochrome (black-and-white), colour, or in three dimensions. It can refer to a television set, a television program, or the medium of television transmission. Television is a mass medium, for entertainment, educational television, news and advertising .
Television became available in crude experimental forms in the late 1920s. After World War II, an improved form became popular in the United States and Britain, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.[1] In the mid-1960s, color broadcasting was introduced in the US and most other developed countries. The availability of storage media such as VHS tape (1976), DVDs (1997), and high-definition Blu-ray Discs(2006) enabled viewers to watch recorded material such as movies. At the end of the first decade of the 2000s,digital television transmissions greatly increased in popularity. Another development was the move from standard-definition television (SDTV)(576i, with 576 interlaced lines of resolution and 480i) to high-definition television (HDTV), which provides a resolution that is substantially higher. HDTV may be transmitted in various formats: 1080p, 1080i and 720p. Since 2010, with the invention of smart television, Internet television has increased the availability of television programs and movies via the Internet through services such as Netflix, iPlayer, Hulu, Roku and Chromecast.
In 2013, 79% of the world's households owned a television set.[2] The replacement of early bulky, high-voltage cathode ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as plasma displays, LCDs (both fluorescent-backlit and LED), and OLED displays was a hardware revolution that began with computer monitors in the late 1990s. Most TV sets sold in the 2000s were flat-panel, mainly LEDs. Major manufacturers announced the discontinuation of CRT, DLP, plasma, and even fluorescent-backlit LCDs by the mid-2010s.[3][4][5] LEDs are expected to be replaced gradually by OLEDs in the near future.[6] Also, major manufacturers have announced that they will increasingly produce smart TV sets in the mid-2010s.[7][8][9] Smart TVs with integrated Internetand Web 2.0 functions are expected to become the dominant form of television set by the late 2010s.
Television signals were initially distributed only as terrestrial television using high-powered radio-frequency transmitters to broadcast the signal to individual television receivers. Alternatively television signals are distributed by co-axial cable or optical fibre, satellite systems and via the Internet. Until the early 2000s, these were transmitted as analog signals but countries started switching to digital, this transition is expected to be completed worldwide by late 2010s. A standard television set is composed of multiple internal electronic circuits, including a tuner for receiving and decoding broadcast signals. A visual display device which lacks atuner is correctly called a video monitor rather than a television.
