What else can I help you with?
How does the operating system help manage resources such as the processor memory storage hardware and peripheral devices?
so as to infom the processor of what it ought to do
Why is microcontroller needed?
A microprocessor cant work as a stand alone unit.to make it work we have to interface memory and input out devices and so the PCB of microprocessor based system will be larger.Microcontroller consists of processor,memory and peripherals on a single chip and so needs no interfacing.Microcontroller can be programmed for any specific task.
What Consists of electronic components that store instructions waiting to be executed by the processor data needed by those instructions and the results of processed data information?
Memory
How does RAM work in electronic devices?
RAM is an acronym for random access memory. RAM acts as a capacitor memory which holds data briefly as it moves through the processor.
Which feature allows devices to bypass the processor and write their information directly to main memory?
The feature that allows devices to bypass the processor and write their information directly to main memory is called Direct Memory Access (DMA). DMA enables peripherals, such as disk drives and network cards, to transfer data to and from memory independently of the CPU, thus freeing up the processor to perform other tasks and improving overall system efficiency. This capability is particularly useful for high-speed data transfers.
What is the case called which houses the processor memory and storage devices in a computer?
It's commonly called the CPU, Central Processing Unit.
Where can you find the processor memory and storage devices on your computer?
If are using Windows XP, find My Computer and right-click on it. Then click on Properties. This will bring up a window that shows all of your processor information.
Why memory management is important?
The speed of processor is very high in comparison to that of user and input/output device.... So if processor is made to wait and work in the speed to user and I/O devices the system becomes very slow... Hence, in order to make full use of processor's speed MEMORY MANAGEMENT is done
What types of transfers must a computers interconnection structure (bus) support?
The Type of transfers that must a computer interconnection structure support thats a bus is the following: (1) Memory to Processor (2) Processor to Memory (3) I/O to Processor (4) Processor to I/O (5) I/O to or from Memory
What is work processor?
processor and main memory
What are different resources managed by O.S?
The different resources of operating system are file system,input/output devices,memory unit,processor....
Differentiate between memory mapped IO and IO mapped IO?
Memory mapped IO is one where the processor and the IO device share the same memory location(memory) while IO mapped IO is one where the processor and the IO device have different memory located to each other.
