JA5. Persistence 1

Statement

  1. Discuss the week’s activities and your observations.
    • Describe what you learned.
    • Did anything surprise you?
    • Did you face any challenges in this Unit? If so, how did you overcome them?
    • How were your peers’ assessments and feedback received?
  2. Briefly describe the Apple macOS and Google’s Android operating systems.
    • Provide some important technical features.
    • Where are they used generally?

Answer 1

  • I started this week on Sunday as usual checking the self-quiz.
  • The week was about I/O devices, Hard disks, and RAIDs disks.
  • We learned about the I/O devices and what are they, how they connect to the CPU and the memory, and the position of drivers in the system.
  • The discussion assignment asked about naming an advance in I/O devices, and talking about it; I chose to talk about wearable devices.
  • The written assignment was about Linux commands, exactly the ones that relate to the file system; e.g. lsblk, find, df, du, lspci.
  • I was surprised when I read my peer’s answers on the discussion assignment; there is so much advancement in the I/O devices, and I didn’t know about them.

Answer 2

  • Apple macOS is a proprietary operating system developed by Apple Inc. for its Macintosh computers. It is the primary operating system for Apple’s Mac computers. macOS is based on the UNIX operating system.
  • Android is a mobile operating system developed by Google. It is based on a modified version of the Linux kernel and other open-source software; it is designed primarily for touchscreen mobile devices such as smartphones and tablets.
  • Technical Comparison between macOS and Android:
    • Android is open-source, while macOS is proprietary (closed-source).
    • MacOS is based on UNIX, while Android is based on Linux.
    • MacOS is developed by Apple, while Android is developed by Google.
    • MacOS is used on Mac computers, while Android is used on mobile devices developed by many manufacturers.
    • Android is compatible with a wider range of devices (hardware), while MacOS only works on Apple devices.
    • MacOS is more secure, due to its closed-source nature, while Android is less secure, due to its open-source nature.
    • Android is more customizable, while MacOS is less customizable.
  • As we saw in the technical comparison, macOS has a completely different purpose than Android, so the comparison is not fair. However, we can compare them in terms of the operating system itself, and the technical features.
  • The fact that Android is Linux-based made it more popular and also able to work on smaller devices with fewer resources like watches and phones.
  • Apple has its proprietary system for smaller devices; they called it iOS, and it is based on macOS.
  • Although the comparison between ios and Android makes more sense, we learned some important technical features of MacOS and Android operating systems.
