The motherboard since it receives the command to shut off the PC from the Microprocessor
Kernel
An operating system is like Windows, Windows 2000, Windows XP, it's the controlling software of your computer. A microprocessor is the CPU, the brain of the computer. It does all the commands, does all the math, and displays the answers on you monitor. So the CPU is called hardware because it is an actual chip, while the operating system is called software because it is millions of lines of computer code.
The operating frequency of 8085 is 3 mhz to 5 mhz
The main advantage of a 64 bit operating system is that it can make use of all the features and performance of a modern 64 bit microprocessor. If you run a 32 bit operating system on a modern 64 bit microprocessor the operating system will not be able to make use of any 64 bit features of the microprocessor and the performance will not be what the microprocessor is capable of.However a 64 bit operating system WILL NOT run at all on a 32 bit microprocessor (or one with a smaller word size) as the microprocessor does not implement the 64 bit features needed for the operating system to work.Note: in the not too distant future microprocessor manufacturers will release 128 bit microprocessors, which will require 128 bit operating systems to use all the features and performance of these microprocessors.
a microprocessor is hardware, it provides the physical mechanism (electronic circuitry) needed to run any software on a computeran operating system is software, it provides the logical mechanism (algorithms) to coordinate the running of all the software on a computerapplications (or apps) are software, they are coordinated by the operating system and run by the microprocessor to perform tasks useful to a human user of the computer
It isn't an issue of advantages, it is an issue of compatibility with your computer. The 64 bit operating system can take full advantage of the capabilities of a 64 bit microprocessor, if your computer has a 64 bit microprocessor. However a 64 bit operating system will not run at all if your computer has an older 32 bit microprocessor; you will have to use a 32 bit operating system on that computer.
PLATFORM
in main memory
A microprocessor runs and internal program called an operating system. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware.
The user is responsible for interacting the operating ststem with the hardware.
Apple is responsible for developing the Mac operating System.
