Specifications of the Kitkat Operating System

As a result, manufacturers have installed Gingerbread on low-end devices with low memory. As a result, the Android operating system (OS) has become big fragmented. However, as Google recently reduced memory requirements, manufacturers are now able to produce more low-cost devices that can be sold in emerging markets. KitKat may ultimately help to reduce the market share of Gingerbread and reduce operating system fragmentation. KitKat includes a new platform support for NFC-based secure transactions via Host Card Emulation (HCE).

Many operating systems also support one or more vendor-specific or open network protocols such as SNA on IBM systems, DECnet on Digital Equipment Corporation's system, and Microsoft specific protocol (SMB) on Windows. It can also support specific protocols for specific tasks such as NFS for file access. Protocols such as ESound and esd can be easily extended over the network to provide local application sound to the sound hardware of the remote system. The operating system must be able to distinguish between requests that should be allowed to process and other requests that should not be processed. Some systems can easily distinguish between "privilege" and "non-privilege", but usually take the form of a requester ID such as a user name. There may be an authentication process to establish identity. User names usually need to be referenced, and each user name can have a password

A program is a strategy and method to follow when using, operating, and maintaining an information system. Specifications for use, operation and maintenance of information systems are usually provided in electronic form of help function, user manual, operator manual, and similar documents.
