Files, mass storage, and I/O in a modern computer system

 

The file management system is software used to determine how files are organized and stored. It allows users to browse, move, and sort files according to different criteria such as date of modification, date of creation, file type, etc. In Microsoft Windows, the file management system is Windows Explorer. On a Mac, the system is called Finder. Input devices allow a user to input data into a computer via a keyboard, mouse, touchpad, etc. while output devices provide the final product, such as a computer monitor, printer, or projector. These are all examples of hardware I/O devices because they are the components the user physically interacts with. The kernel's I/O subsystem provides numerous services, such as "I/O scheduling, buffering, caching, spooling, device reservation, and error handling" (Silberschatz et al., 2014).

How main and virtual memory solve memory management issues

Image
  In the memory management diagram, the base and limit registers are used to provide the range of legal addresses the process may access (Silberschatz et al. 2014). The hardware address protection diagram shows how addresses are compared with registers, with a trap to capture any programs attempting to access the operating system in user mode. The multistep processing diagram displays steps a user program may go through before being executed (Silberschatz et al. 2014). Dynamic relocation diagram shows how “the value in the relocation register is added to every address generated by a user process at the time the address is sent to memory” (Silberschatz et al. 2014). Virtual memory can provide many benefits to the system and user by providing larger address space, allowing more programs to be run at the same time, and using less I/O to load or swap user programs into memory (Silberschatz et al. 2014).

How operating systems enable processes to share and exchange information

Image
  A critical section is the part of the process where the code for accessing the shared resources is written. The critical section problem refers to a solution which allows the processes to cooperate when they share common resources. In order for this to happen, a process must take care of three properties: mutual exclusion, progress, and bounded wait.          Mutual Exclusion: Only one process can execute its critical section at a time.           Progress: If a process doesn’t want to enter in its critical section, it should not be permitted to block another process from entering           Bounded Waiting: Bounded time up to which the process has to wait to enter its critical section after making the request. Ensures every process requesting to enter its critical section get the chance within the finite amount of time.   A software-based solution to critical section problem discussed in our te...
