Study Notes

Computer Components and Operating Systems

Modern computers include processors, memory, storage (disks/flash), input/output devices (printers, keyboard, mouse, display, network), and more.
Managing these components directly is complex for application programmers.
Operating systems (OS) provide a simplified interface to the computer hardware and manage resources.
Smartphones and tablets (like iPad) are miniaturized computers with OS (e.g., iOS).
iOS is similar to macOS.
Android devices use Linux as their OS; the "Android" layer sits on top.
UNIX is the most popular OS, with variants like macOS and Linux.
Experiences with Windows, Linux, FreeBSD, or macOS are common.
This book focuses on UNIX/Linux, with in-depth discussion of Linux in Chapter 10.
UNIX (FreeBSD, macOS) had evolutionary development and Linux has a new codebase, similar to UNIX.
Google adopted Linux to develop the Android OS due to the high development cost of a new, secure OS.

Operating System History and Types

The book covers operating systems’ history, types, basic concepts and structure.
Subsequent chapters will have more detail.
