purposes. Various applications can loaded.
◍ Give examples of general purpose system..
Answer: Desktops, Laptops, Smartphones
◍ Non-Volatile.
Answer: Data is retained in the memory when the power is turned off. ROM
is an example of this type of memory.
◍ Memory Address.
Answer: A number assigned to a storage location in memory where a single
piece of data is kept.
◍ Main Memory.
Answer: The physical memory that can be directly accessed by the CPU
(unlike secondary storage)
◍ What are the advantages of general purpose systems?.
Answer: - Very popular- Cheap- Well tested- Wide support (Easy to use)-
Not specific to a particular user (E.g. Microsoft)- Capable of development
