Hey everyone. Welcome back to Tech Archive. Today we’ll be starting to delve into the large and expansive world of Operating Systems as an Introductory Session to the following topics. To start it all off, we have to ask ourselves this important question. What is an operating system?
After reading a couple of definitions, I have identified the main points and have come up with a standard definition. An Operating System is the system software that manages, allows and regulates communication between the software, hardware, and the user, allowing ease of access for the running of processes and completion of tasks, both foreground and background, that makes computing easier, faster, more reliant and efficient. An Operating System is most commonly known as an OS.
In order to facilitate this process and task management and software to hardware interaction with themselves and the user, the OS must make use of system hardware which includes the use of:
o Storage Devices: consisting of both internal and external drives
o Network Devices: consisting of routers and network cards
o Input Devices: consisting of keyboards and mice/interactive touchpad.
o Output Devices: consisting of Monitors and Printers.
o Internal Components: consisting of CPUs, Video Cards, RAM chips, Sound Cards and Motherboards.
Although all of these are needed for the operation of an OS, the Internal Components and Storage Devices are necessary, as the computing device needs these components in order initiate the start-up sequence the boot the OS. Through this, the Operating System can then manage and allocate the resources provided by the Internal Components and Storage Devices to store and run software and processes. However, since the OS is a special software, any software that one wants to run on it has to be specifically built for the OS binaries.
Examples of Operating Systems include:
(For PCs, Desktops and Laptops)
* Microsoft Windows – 98, XP, 7, 8, 8.1, 10, etc.
*Linux – Debian, Ubuntu, Arch, Fedora, etc.
(For Mobile Devices)
*Microsoft Windows (deprecated)
The world is filled with many interesting and complex Operating Systems and in the following weeks, we will explore these operating systems and look into how they work and impact our lives. What you may find will interest you, this I promise you. However, I encourage those who read this to do their own research, and explore for themselves. A new adventure awaits. As I close, remember, Be Internet Safe!
