Implementation Of A New Operating System

Operating Systems are complex pieces of software that are designed for powerful hardware, easily capable of running many programs at once, the prioritize hardware task requests known as ‘system calls’ and allocate them memory space or processing time as needed.

Processor: A computer processer, otherwise known as the CPU (Central Processing Unit) is a part of the computer that receives input and decides that the output will be. Many modern CPUs are capable of processing trillions of calculations per second. The speed of a processor measured by how many operations a CPU can do in one second; this is done in MHz or GHz (Megahertz or Gigahertz). A processer with the speed of 1 MHz does 1,000,000 operations per second, and a 1GHz processer does 1,000,000,000 operations per second. This is known as the clock speed.

Busy waiting is a technique in which a process repeatedly checks to see if a condition is true without getting the processor time. While a process is in its critical section, any other process that tries to enter its critical section must loop continuously to get the critical section. This will make the process eat CPU (usually). That is just busy for waiting the processor time.

Generally processes can be described as I/O bound or CPU bound. I/O bound spends more time in doing I/O operations rather than other computations. CPU bound is contrast to I/O bound, which spends time doing all other

The process needs many resources to complete certain tasks these resources include CPU time, memory, files and I/O devices for its task to be complete. These resources are either allocated to the process when it is running or is given to the process when it is created.

3.8) Short term scheduler or CPU scheduler: selects a process from the processes (that are in memory) that are ready to execute and allocates the CPU to it.

In contrast, the parallelism is a condition that comes when at least two threads are executing at the same time''. It is possible for two threads to make progress, though not at the same

Medium-term scheduler: It selects processes from the ready or blocked queue and removes them from memory. Then it reinstates them later to continue running.

The processor (otherwise known as CPU) is the very soul and performance core of the computer system; it is what allows the operating system and other software applications to-run. Every program demands dedication from the processor to decode commands that are then actionedinside the CPU to make them work.When a program is running, the CPU has to make every command work consistently one after the other. However, modern processors have the power to process commands side by side. This means that the quicker the commands are executed, the quicker the program responds to the user. Central Processing Units (CPUs) play an important role when it comes to maintaining

Asymmetric multiprocessing, since the tasks are divided among the processes, each process runs on different software and roles whereas in symmetric multiprocessing each CPU runs on same OS.

Special hardware can differentiate the multiple processors, or the software can be written to allow only one boss and multiple workers. For instance,

Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed by the user even if the company fails [1]. Moreover, updates for Linux are available every six months [1]. Nowadays, Linux is in constant development by

Concurrent Events: Since it takes time to process an event, other events may stack up. In this case a software stack using push and pop is often used to track events. Alternatively where few events are expected and speed is of essence a hardware stacks using registers could be used to accomplish the same task.
