- Associativity: Caches can have different associativity levels ranging from direct-mapped (each block maps to only one location in cache) to fully associative (any block can map anywhere in cache).
- Replacement Policies: When new data needs to be loaded into cache while it’s full, replacement policies determine which existing entry should be evicted. Common policies include Least Recently Used (LRU), First-In-First-Out (FIFO), and Random Replacement.
|Capacity||Limited capacity relative to main memory|
|Hierarchy||Multi-level structure with varying speeds and capacities|
|Associativity||Range of associations determining how blocks map onto locations in cache|

Imagine that Company X is facing challenges with their current computing system, which often experiences bottlenecks and delays during complex tasks. In an effort to mitigate these issues, they decide to implement instruction pipelining—a technique that aims to improve overall performance by allowing multiple instructions to be executed simultaneously in different stages of processing. Through this approach, each stage can focus on a specific operation (such as fetching, decoding, executing, and storing), enabling parallel execution and reducing idle time.
To better understand how Instruction Pipelining optimizes performance, consider the following benefits:

Imagine a scenario where a computer system is running multiple programs simultaneously, each requiring a significant amount of memory. Without an efficient memory management technique, the system would quickly run out of physical memory, resulting in slow performance and potential program crashes. This is where virtual memory comes into play, providing a solution to effectively manage limited physical memory resources.
Virtual memory is a technique that allows the operating system to use disk space as an extension of physical memory. By using virtual addresses instead of physical addresses, it enables the illusion of having more available memory than what is physically present. The concept can be better understood by considering how it works in practice.
Firstly, when a process executes, its instructions and data are loaded into physical memory pages from secondary storage (e.g., hard drive).
