Introducing memory management concepts

There are several concepts related to the organization and management of random-access memory (RAM). Understanding these concepts will allow you to make the memory investigation process more conscious and effective. Let's start with the address space.

Address space

RAM is an array of memory cells, each with its own physical address used to access that cell. However, processes do not have direct access to physical memory. This is because processes can easily harm the operating system and even cause it to crash completely when interacting with physical memory. Moreover, the use of physical addresses by processes makes it difficult to organize the simultaneous execution of programs. To solve these problems, an abstraction known as address space was created.

An address space is a set of addresses that can be used to access memory. Each process has its own isolated address space, which solves the problem of security and isolation of...
