CTOS is full form CenTral Operating System

What is CenTral Operating System?

Operating systems evolved to provide more convenient access to computing resources, and also to provide more efficient use of those resources. For convenience, a standard interface to the virtual machine is provided. For efficiency and convenience, multi-tasking is provided. Multi-tasking provides the programmer with illusion of concurrency on single processor architectures. This illusion greatly simplifies the design of programs handling streams of input and output to and from different devices (sources and sinks). Neither the operating system nor the applications programmer can know in advance which events will occur in what order. It is much more natural to model separate sources and sinks as being handled by separate processes. Thus we can identify a set of base objects that exist in the virtual machine (see figure #fnos1#93>:

Users
Processes [Which may be divided into various levels of threads of control]
Filestore [Usually provided as a uniform view of Input/Output devices, with a base set of methods and some refinements for special case devices]. Communications Channels
Furthermore, we can identify a set of base operations on these objects such as:
Create/Destroy (User/Process/File/Directory/Channel)
Initialise (User/Process/File/Directory/Channel)
Identify/Authenticate a User/Process/File
Change Permissions for User/Process/File/Channel
Send/Receive Data to/from File/Channel
Control Device...
