  •        Operating systems usually come  preloaded  on any computer you buy. Most people use the operating system that comes with their computer, but it's possible to upgrade or even change operating systems. •        The three most common operating systems for personal computers are  Microsoft Windows ,  Apple Mac OS X , and Linux .

Computer architectures

  1. Von Neumann Architecture: This is the most common and widely used architecture in modern computers.   It features a single memory space for both instructions and data, accessed through a shared bus.   The CPU fetches instructions and data from this shared memory, processes them, and stores the results back in the same memory.   Example: Desktops, laptops, and smartphones.   2. Harvard Architecture: This architecture uses separate memory spaces for instructions and data.   This separation allows for faster instruction fetching and execution, especially beneficial for applications requiring high performance.   Example: Microcontrollers and embedded systems.   3. RISC (Reduced Instruction Set Computer): RISC architectures have a smaller set of simpler instructions, leading to faster execution times.   They rely more on hardware for instruction execution, making them more complex to design but also more efficient.   Example: Modern high...
