Describe three general methods for passing parameters to the operating system?
1) Pass parameters using registers(directly). 2) Store the parameters in a table in memory and the table address is passed in a register to the OS. 3) Push(store) the parameters onto a stack(by the program) and "pop" off by the Operating System.

Concurrent process uses of operating system?
processes are concurrent if they exist at the same time.concurrent process can function completely indepently to one another. two process are concurrent if their execution can overlap in time; that is, the execution of the secon process starts before the first process completes. concurrent processes generally interact through the following mechanisms: Shared variables Message passing
How do user programs and system services interact in a microkernel?

Why the operating system important to the computer?
The operating system provides several important services:It creates and maintains file systems on disks and other media, and provides a device-independent interface for programs to create, read and modify files and directories.It creates and manages processes and threads, including time-sharing among them.It manages virtual memory and allocates separate address spaces for each process.It loads programs into process address spaces and starts their execution, and cleans up after them when they are finished.It catches attempts by programs to access memory outside the address space that has been allocated to them.It provides message-passing services for interprocess communication.It provides network I/O services to programs.

Why is string type array used in the parameter of the main method?
A user can run a program from the operating system command line, passing parameters. For example, in the case of a Java program: Java MyClass John Doe 1 2 3 In this example, the program "Java.exe" receives all the parameters starting with "MyClass" - a total of 6 parameters in this example. Then, the JVM runs the class "MyClass", and this class receives the remaining five parameters - as an array of strings. You can pass any information to a program this way; for example, a program that processes files might receive the file name, or a directory (folder) name as a parameter.
Does passing static strings as parameters to a method create a copy of the String or passes its reference?
Java always follows a pass by value approach.

What is the purpose of passing parameters by pointers?
There are two ways to pass parameters to a method. 1) Pass by value 2) Pass by reference.(i.e. pass by pointers). For here, I would say, whenever you required to change the properties/value of the parameter by the method you called you should the approach (2). ie. pass by pointers.
