Networking is equally, or more important, would also be a good starting point, will come along soon. But, OS-Operating Systems come earlier in the 'begats', they've been around since the 's and we start with them: An operating system OS is system software that manages computer hardware and software resources and provides common services for computer programs.
All computer programs, excluding firmware, require an operating system to function. This definition acknowledges that some computers only run one program which has been burned into a ROM or the CPU as 'firmware'.
Many computers embedded in appliances and other devices only have one function. It starts when the power is turned on and runs until powered off. Examples of familiar operating systems for personal and mobile computers are Windows and Mac, iOS and Android.

This is commonly called 'the bootup process', as in the adage 'pick yourself up by your bootstraps'. We're used to waiting several seconds or longer while our PCs and notebooks boot up, or our smartphone.
Larger machines like servers, mid-range, and mainframes and even smaller computers embedded in Routers, household appliances, TVs, or DVD Players all 'boot up' when the power's turned on. After the computer's booted, it's ready to run our applications. Prior generation computers' bootup processes were manual, with no bootstrap loader.
They involved flipping switches to set the address of the magnetic or paper tape drive, card reader, or disk holding the 'boot image' necessary to run the application at hand. If the BIOS devices are connected without error, the boot process continues to seek the bootable device configured into the BIOS, which may be a hard disk or solid-state drive, usb, or network interface.
When the OS on the bootable device has been loaded our computer's ready to run applications.
Most computers momentarily flash their BIOS access key on the monitor or command line early in the bootup sequence.
Googling something like 'how to enter bios on my dell xps' often gets a useable response. Please, enter the BIOS on a couple of the notebook and desktop computers at your fingertips and consider what's there. The BIOS provides a simple menu to check and change settings.
This ability to alter the bootup process must be secured and managed carefully! Otherwise, some crook can load their own rogue OS and pillage the machine.
An employee who can reboot a machine and enter the BIOS has a whole 'nother, rich, vector to attack the employer's networks, servers, and co-workers machines.
BootCamp is a Mac product, and the Windows Disk Management Utility are some other options for 'dual booting' a notebook or desktop computer. Dual-booting software provides a 'boot menu' that appears whenever the computer is restarted.
Several differently configured OS may be on the machine and you pick the one to run after power up. It runs one OS at a time, with the only communication being their shared file system. Booting from a 'Live Distro' is a good way to see if a machine will run a Linux flavor like Ubuntu or Fedora.
This circumvents any file security that might be provided by Windows, and all un-encrypted data is available to whoever boots the live distro"It's IBM's goal to be the undisputed leader in enterprise cloud," Willie Tejada, IBM's chief developer evangelist, told ZDNet.

When the laptop market overtook the desktop market, Blue Tech Inc., a leader in desktop technology, was left at a competitive disadvantage. Later, Blue Tech Inc.'s management channeled all of the company's efforts and revenue to develop an efficient laptop from scratch in less than a year.
