Describe the Background and History of Linux 5
?– Utilities Linux includes a wide variety of utilities that you can use to
complete operating system management tasks, such as maintaining the file
system, editing text files, managing running processes, and installing new
software packages.
?– User Interface Of course, you as the end user need some means of
interacting with the operating system. Linux includes both a command-line
interface (CLI) and a graphical user interface (GUI). We??™ll explore both of
these interfaces later in this chapter.
Let??™s next review how Linux came into being.
The Historical Development of Linux
Linux is somewhat of an anomaly in the software development industry. Most
software products, whether they are applications or operating systems, are developed
as a part of a well-organized design and development effort. I??™ve personally worked
SCENARIO & SOLUTION
How does an operating system manage applications? Operating systems manage applications by allocating
each application a memory range it can use.
