Concept explainers

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

A multithreaded web server wishes to keep track of the number of requests it services (known as hits). Consider the two following strategies to prevent a race condition on the variable hits. The first strategy is to use a basic mutex lock when updating hits: int hits; mutex_lock hit_lock; hit_lock.acquire(); hits++; hit_lock.release(); A second strategy is to use an atomic integer: atomic_t hits; atomic_inc(&hits); Explain which of these two strategies is more efficient and why?

Hey the virtual address 11123456 is incorrect for this question. The virtual address is 0x33C25977E083. Please answer the question below instead of copying the answer from chegg or somewhere else. A computer provides a virtual memory space of 248 bytes. The computer has 16 GiB of physical memory. Virtual memory is implemented by demand paging, and the page size is 4 MiB. A user process generates the virtual address 0x33C25977E083.Explain how the system determines the physical address
Imagine that to save space, the TLB drops the Read/Write and User/Supervisor protection bits. The page table still has the protection bits. However, when moving from user mode to kernel mode (or vice versa), the TLB is flushed. i) Could a process access memory belonging to another process? How? ii) Could a process access memory belonging to the kernel? How? iii) What problem could arise if a process can write memory it is normally supposed to only read?
