Recommendation: Your recommendation should map the technology you have described above to the overall requirements of TSI and their endeavor to implement TSO OS in their back office. Your recommendation should not be a simple regurgitation of the facts above. Imagine you are presenting a summary of your findings and a recommendation to a busy executive. Give a crisp, one-paragraph summary that defines how TSI will move from the current state to a future state that implements an operating system with all of the capabilities necessary to meet its requirements.

Explanation / Answer
Multiprogramming:
Tech Description:
Executing multiple program at a time.
Business Requirement:
to save the cpu time.For efficient use of cpu we will use this multiprogramming
Application Benefit:
Utilization of cpu will be more
Implementation Tasks:
Using browser to listen to music online , using msword to edit text .
Two programs can be used parallel independent of each other
Multiprocessing:
Tech Description:
Using multiple processors to run the task simultaneously.
Business Requirement:
All processors coordinate each other to process a single task with a less time
Application Benefit:
Time taken to complete a task will be very less compared to multiprogramming
Implementation Tasks:
Servicing the jobs in the queue as fast as possible by running parallely on multiple cpu’s(Processors)
Multithreading:
Tech Description:
the ability of a central processing unit (CPU) or a single core in a multi-core processor to execute multiple processes or threads concurrently,
Business Requirement:
Running the tasks parallely
Application Benefit:
We can save time
Implementation Tasks:
Listening to music in browser in one tab and watching videos in another tab
Virtual Memory:
Tech Description:
Illusion of very large memory. But in read world it does not exist
Business Requirement:
to execute the tasks which are larger than the size of main/primary memory
Application Benefit:
No need to have primary memory of equal size to execute a task of large size
Implementation Tasks:
Provide a facility of no need of loading the entire task into the ram to start execution
System Call Interface:
Tech Description:
It is a interface between the processes who requested the service and the kernel
Business Requirement:
a system call is a request to the kernel for a service. The system call interface is the basic interface between a program and the kernel. The programming library, e.g. libc, has APIs on top of the basic system calls, provided by the kernel, which further ease the job of the developer
Application Benefit:
To ease the developer to work on his task without bother about the underlying system architecture and system calls
Implementation Tasks:
When using api the system call interface provide a way for translator between the underlying system call and api function calls
Security:
Tech Description:
A way of controlling the access to specific resources
Business Requirement:
To implement the access level permission to different user when using specific resources
Application Benefit:
Controlling the unauthorized acess to resources
Note:RESOURCES MAY BE ANYTHING LIKE FILES,CPU TIME,MEMORY..ETC
Implementation Tasks:
Provides the things that are eligible by the user
Device Drivers:
Tech Description:
It is a program /software that controls a particular type of device that is attached to your computer
Business Requirement:
To allow the computer to communicate efficiently with the devices attached to it
Application Benefit:
No need worry about the device which we are using.
software interface to hardware devices, enabling operating systems and other computer programs to access hardware functionality without needing to know precise details of the hardware being used.
Implementation Tasks:
Acess as medium for communication between computer program and the devices attached to the computer
Fault Tolerance:
Tech Description:
It is a property/functionality that enables a system to continue operating properly in the event of the failure of one of the components .
Business Requirement:
to make system components independent of each other
Application Benefit:
Abiltity to work even a failure occurred in some part of system
Implementation Tasks:
Even one processor failed in multiple processors the remaining processors continue to work
.the task left by the failed processor will be shared by the remaining processors.
