Chapter 5

1. Computer memory can be described as a single concept – the Dynamic RAM (DRAM), or as a combination of all the memory units that the computer contains, starting with the registers and cache memory, and ending with the hard drive. From the programmers' perspective, DRAM is of the most interest because it holds the instructions and data of the program running in the computer.
2. Virtual memory is an approach to efficiently manage the physical memory of the computer. Typically, the operating system incorporates virtual memory to handle memory accesses from programs and to efficiently allocate chunks of memory to particular programs.
3. In C++, we use the new and delete operators to allocate and deallocate memory space.
4. delete deallocates the space allocated for a single object, while delete[] is used for dynamic arrays and frees all the elements of the array on the...
