Uses of low-level languages

• It is technically possible for any program to be written in a low-level language, but most programmers choose high-level languages because they are easier to write and debug.

  There are however some tasks that are better suited to a low-level language.
• Embedded system


  A complete computer system that has a dedicated function
• Embedded systems


  • Designed to complete a limited number of specific tasks very efficiently
  • Usually restricted by size and therefore cannot have huge processors that require cooling, or large storage devices that would add weight and heat to a system
• The programs that run on embedded systems need to be efficient and make the best use of the processing power and memory available
• Low-level languages


  Allow a programmer to create optimised programs for embedded systems
• Low-level language programs are extremely efficient at completing their tasks
• Device drivers are programs that allow a computer to interact with a peripheral, like a mouse or a printer. Operating systems install and manage device drivers for every peripheral connected to a computer.
• Low-level languages allow precise control of a piece of hardware and that is why they are used for device drivers. A device driver written in a low-level language allows the CPU to communicate with the peripheral directly, receiving data and issuing commands quickly and efficiently.
