Firmware, Flat-File CMS, Flat Rate
In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware can either provide a standardized operating environment for more complex device software (allowing more hardware-independence), or, for less complex devices, act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems, consumer appliances, computers, computer peripherals, and others. Almost all electronic devices beyond the simplest contain some firmware.
Firmware is held in non-volatile memory devices such as ROM, EPROM, or flash memory. Changing the firmware of a device was rarely or never done during its lifetime in the past but is nowadays a common procedure; some firmware memory devices are permanently installed and cannot be changed after manufacture. Common reasons for updating firmware include fixing bugs or adding features to the device. This requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Firmware such as the ROM BIOS of a personal computer may contain only elementary basic functions of a device and may only provide services to higher-level software. Firmware such as the program of an embedded system may be the only program that will run on the system and provide all of its functions.
Before the inclusion of integrated circuits, other firmware devices included a discrete semiconductor diode matrix. The Apollo guidance computer had firmware consisting of a specially manufactured core memory plane, called "core rope memory", where data was stored by physically threading wires through (1) or around (0) the core storing each data bit.
A Flat-File Content Management System (in short Flat-File CMS) is a content management system in which the text contents are stored exclusively in files, which means that no relational database is required for its operation. By dispensing with a database, flat-file CMSs are not only suitable for inexpensive web hosting without a database, but also for web server performance that is not too high. In addition, compared to a content management system with a database, the maintenance effort is much smaller and the relocation of a website is easier. Templates (design templates) are available for the design, plugins are available for the functional extension. Most flat-file CMS are open source and therefore free of charge. BTW: such a Flat-File CMS with almost thousand web pages can be faster than a database-based CMS. You are surfing just now on such a website and the site building is fast enough if you are not sitting on the other side of the world, right?
A flat fee, also referred to as a flat rate or a linear rate refers to a pricing structure that charges a single fixed fee for a service, regardless of usage. Less commonly, the term may refer to a rate that does not vary with usage or time of use.
