Advantages of UNIX
- It is multitasking, therefore, multiple programs can run at one
time.
- It is multiuser, allowing more than a single user to work at any
given time. This is accomplished by sharing processing time between each
user and utilizing distributed computing systems.
- It is safe, preventing one program from accessing memory or storage
space allocated to another, and enables protection, requiring users to
have permission to perform certain functions, i.e. accessing a directory,
file, or disk drive.
