COMPUTER FUNDAMENTALS

Detailed explanation-1: -A personal digital assistant(PDA) is an example of real-time operating system. Metropolitan area networks cover an area the size of an average to large city.

Detailed explanation-2: -Embedded operating systems are designed to be used in embedded computer systems. They are designed to operate on small machines like PDAs with less autonomy. They are able to operate with a limited number of resources. They are very compact and extremely efficient by design.

Detailed explanation-3: -Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.

Detailed explanation-4: -The transmission protocol between a computer and its peripheral devices is handled by a device driver, or simply driver. An external peripheral device must have a corresponding port and cable that connects it to the computer. The data path between the microprocessor, RAM, and peripherals is the data bus.

Detailed explanation-5: -Embedded operating systems are computer operating systems created specifically for embedded computers. They’re designed to work on machines with limited autonomy (e.g. PDAs). They are designed to be small and efficient, and they can run with a little number of resources.
