Hey!☺️
____________________________________________
Unix Operating System is an environment which is widely used in different vendor
products. It is an approved OS in terms of performance, utilization and also security.
In Internet environment Unix machines are mostly used and it has started to be
standard as an Operating System and dominant over other systems. Some derivates
are Red Hat Linux, Suse Linux, SUN Solaris, IBM AIX, MAC OS X, Debian Linux,
FreeBSD, OpenBSD, etc.
System has a modular structure in which resources such as memory, CPU and IO are
treated in different layers. This behavior makes Unix more flexible for increasing
necessities of Information Technology.
Os layers:
• user programs
• Input/output management
• Operator-process communication
• Memory management
• CPU scheduling
• Hardware
Unix Operating System is designed according to security concepts to provide better
qualitative service. It is a multithreaded, time-sharing environment which is very
portable for development and enhancements.
Some properties of basic Unix environments are the followings:
•Designed to be a time-sharing system.
•Has a simple standard user interface (shell) that can be replaced.
•File system with multilevel tree-structured directories.
•Files are supported by the kernel as unstructured sequences of bytes.
•Supports multiple processes.
.Hope It helps
