When you load a program in windows, the pc copies the program from the mass storage device to RAM and then runs it.
RAM is an abbreviation for random access memory. RAM is used to store programs and data that can be read and altered in any order. RAM has the advantage over hard disk drives as it is more convenient and faster to read and write from.
One of the disadvantages of this type of memory is that it cannot store data permanently as the data is lost when the computer is shut off.
RAM is stored in microchips of the pc and can bear only a small amount of data.
Dynamic random access memory and static random access memory are the two main types of RAM that differ in that the static random access memory the data does not need to be constantly refreshed.

How do clustered systems differ from multiprocessor systems? what is required for two machines belonging to a cluster to cooperate to provide a highly available service?
In order to complete a distributed computational task, clustered systems are often built by fusing several computers into a single system.
On the other hand, multiprocessor systems could be a single physical object made up of numerous CPUs.
A multiprocessor system is more strongly coupled than a clustered system. While the processors in a multiprocessor system might be able to interact using shared memory, clustered systems require messages.
The state on the two machines needs to be copied and regularly updated for two machines to deliver a highly available service. If one of the machines breaks down, the other might step in to take over.

Explain the impact of the continuing evolution of computer hardware and the accompanying evolution of operating systems software.
As computer hardware continues to evolve, so too does the software that runs on it. Operating systems are constantly being updated to take advantage of new hardware capabilities and to address security concerns. This continuing evolution has a major impact on the way we use computers.
For example, new hardware developments have led to the creation of new types of devices, such as touchscreen laptops and tablets.
Operating systems have been adapted to make use of these new devices, and the way we interact with computers has changed as a result. Similarly, the way we store and access data has also evolved, thanks to advances in storage devices and networking technology.
The ongoing evolution of computer hardware and software is thus having a major impact on the way we live and work. As new capabilities are introduced, we find new ways to use computers to improve our lives.
