  Virtual memory is a technique that allows the operating system to make more efficient use of physical memory. It does this by creating a virtual address space for each process, which is much larger than the amount of physical memory available. When a process accesses a virtual address, the operating system translates it to a physical address. This allows processes to use more memory than is physically available, and it also helps to protect processes from each other.

• Page tables
  

  Page tables are a data structure that is used to translate virtual addresses to physical addresses. Page tables are stored in memory, and they are accessed by the operating system when a process accesses a virtual address. Page tables are an essential part of virtual memory, and they help to ensure that the operating system can efficiently and securely translate virtual addresses to physical addresses.

• Slab allocator
  

  The slab allocator is a memory allocator that is used in the Linux kernel. The slab allocator allocates memory in fixed-size blocks, which are called slabs. Slabs are designed to improve the performance of memory allocation and deallocation, and they are particularly useful for allocating memory to objects that are of a similar size.

• Zone allocator
  

  The zone allocator is another memory allocator that is used in the Linux kernel. The zone allocator divides memory into zones, which are based on the physical characteristics of the memory. The zone allocator helps to ensure that memory is allocated efficiently, and it also helps to improve the performance of the kernel.
