Klasifikasi Sistem Operasi
Multiuser
Multitasking
Multiprocessing
Multithreading
• when two or more users can work with
programs and share peripheral devices
(printer, scanner, fax)
• multiple applications operated at the
same time
• more than one CPUs that can be
shared
• smaller parts of a program are loaded
when needed by OS

Mainframes
 Mainframes run multiple operating
systems and operate not as a single
computer but as a number of virtual
machines.
 They are typically manufactured by
large companies for large-scale
computing purposes

 z/OS from IBM
While IBM System z™ servers are
supported by a number of different
operating systems, their most
advanced features are powered by
z/OS

P'HE PROPERTIES
Embedded Systems
 Embedded systems are special-purpose
systems in which the computer is
completely encapsulated by the device it
controls.
 Embedded systems perform pre-defined
tasks that have very specific requirements.
 Real-time operating systems are embedded
systems with certain time requirements

Unix-like OS
 The operating system Unix was
developed in 1960 by a group of AT&T
employees.
 Free Unix-like operating systems can be
used, studied, modified and
redistributed by anyone with no
restrictions.
P'HE PROPERTIES
Unix-like OS
 It's a diverse group of operating
systems with several major subcategories including BSD, and Linux.
 Unix like operating systems run on a
variety of computers but more
frequently on server systems and in
academic and engineering environments
due to high stability for any kind of
processing

P'HE PROPERTIES
WebOS
 The WebOS (Web Operating System) represent
a new form of virtual operating system that
runs directly in your browser.
 The main advantages of a web operating
system is that you can access it from anywhere
but it's very arguable if it's really an operating
system or not because it runs over a browser
window and have no relation whatsoever with
the hardware and its drivers.
 You will still need an operating system to run a
WebOS.
