Data communications in the context of Flow control (data)

PT Telekomunikasi Indonesia (Persero) Tbk (lit. 'Telecommunications Indonesia State-owned Public Limited Company') officially shortened into PT Telkom Indonesia (Persero) Tbk, also simply known as Telkom, is an Indonesian multinational telecommunications conglomerate with its corporate headquarters in Bandung and its operational headquarters in the Telkom Landmark Complex in Jakarta. Telkom is listed on the Indonesia Stock Exchange and has a secondary listing on the New York Stock Exchange—the only Indonesian company, currently listed there (but not the first—the first was Indosat, which delisted from the exchange in 2013). The government of Indonesia owns over half of the Telkom's outstanding shares.

Telkom has major business lines in fixed line telephony, internet, and data communications. It is operated as the parent company of the Telkom Group, which is engaged in a broad range of businesses which consist of telecommunication, multimedia, property, and financial services. Since 2008, Telkom Indonesia began changing its business, focusing on infrastructure, systems, organization and human resources, and the corporate culture, in order to face the rising competition.

Physical media refers to the physical materials that are used to store or transmit information in data communications. These physical media are generally physical objects made of materials such as copper or glass. They can be touched and felt, and have physical properties such as weight and color. For a number of years, copper and glass were the only media used in computer networking.

The term physical media can also be used to describe data storage media like records, cassettes, VHS, LaserDiscs, CDs, DVDs, and Blu-ray discs, especially when compared with modern streaming media or content that has been downloaded from the Internet onto a hard drive or other storage device as files.
