Study Notes
Memory Management Techniques
- Match memory management techniques with their descriptions: • Paging: divides physical memory into fixed-size blocks called pages • Segmentation: divides a program into logical units called segments • Swapping: transfers pages or segments between main memory and secondary storage • Virtual Memory: uses both hardware and software to enable a computer to use more memory than physically installed
Hardware Components
- Match hardware components with their functions: • MMU (Memory Management Unit): translates logical addresses to physical addresses • Cache Memory: acts as a fast buffer between main memory and CPU • Registers: stores data temporarily while it is being processed
Address Translation
- Match address translation components with their purposes: • Page Table: stores the mapping between virtual and physical addresses • Page Frame Number (PFN): the physical address of a page • Page Offset: the displacement of a word within a page
Memory Management Concepts
- Match examples with correct memory management concepts: • A process using more memory than physically available: Virtual Memory • Dividing a program into logical units: Segmentation • Transferring pages between main memory and secondary storage: Paging
Memory Management Schemes
- Match memory management schemes with their descriptions: • Contiguous Allocation: assigns contiguous blocks of memory to a process • Non-Contiguous Allocation: assigns non-contiguous blocks of memory to a process • Dynamic Memory Allocation: allocates memory at runtime
Addressing Schemes
- Match addressing scheme requirements with their components: • Absolute Addressing: requires the physical address • Relative Addressing: requires the base address and relative offset • Indirect Addressing: requires the address of a memory location that contains the required address
Memory Management Advantages
- Match advantages with the memory management scheme they apply to: • Efficient use of memory: Virtual Memory • Fast access to memory: Cache Memory • Protection from memory conflicts: Paging
Studying That Suits You

Description
Test your knowledge of non-contiguous memory allocation, which involves partitioning a program into small units that can reside in different parts of the memory, requiring hardware support and utilizing various methods such as segmentation. This quiz covers topics related to memory management schemes, program segmentation, and logical units within a program.
