How is memory allocation and structure organized in a computer?

Memory in a computer is organized and structured for efficient storage and access to data. Key aspects of memory allocation and structure:

• Main types of memory:

  • Random Access Memory (RAM) — for temporary storage of data and instructions during program execution.
  • Persistent memory (ROM, SSD, HDD) — for long-term storage.

• Address space: Memory is divided into addresses, each pointing to a specific byte.

• Process memory structure:

  • Code (text segment) — contains executable machine code.
  • Data — static and global variables.
  • Heap — dynamically allocated memory during runtime.
  • Stack — stores local variables and function call information.

• Memory management: In languages like Go, there is a garbage collector that automatically frees unused memory, simplifying development.

Example: When a Go program starts, a stack is created for each goroutine, where local variables are stored, and dynamic objects are allocated on the heap and managed by the garbage collector.
