Memory Architecture and Concepts

Memory Architecture and Concepts

Understanding memory architecture is fundamental to effective analysis:

Memory Organization:

  • Physical Memory: Actual RAM chips and addresses
  • Virtual Memory: Abstract address space for each process
  • Page Tables: Maps virtual to physical addresses
  • Kernel Space: Protected memory for OS operations
  • User Space: Memory allocated to applications

Key Memory Structures:

  • Process Control Blocks: Process metadata and state
  • Thread Information: Execution context and stack
  • Handle Tables: Open files, registry keys, and objects
  • Network Sockets: Active connections and ports
  • Driver Objects: Loaded kernel modules
  • Registry Hives: Cached registry data
