Processor Pipelining: Hazards, Solutions, and Parallel Architectures
Understanding Pipeline Hazards
There are three main types of pipeline hazards that can occur in a pipelined processor:
1. Structural Hazards
Structural hazards occur when there is a conflict in accessing a shared resource, such as a memory location or a functional unit, by multiple instructions in the pipeline at the same time. This can happen when two instructions require the use of the same resource simultaneously. Structural hazards can lead to pipeline stalls or incorrect results if not properly

Major Applications of Computer Graphics
- Entertainment and Media: Used in movies, animation, video games, and visual effects to create realistic or fantastical scenes.
- Computer-Aided Design (CAD): Employed by architects, engineers, and designers to create precise technical drawings and 3D models of buildings, vehicles, and machinery.
- Medical Imaging: Helps visualize complex structures of the human body through techniques like MRI, CT scans, and 3D reconstructions.
- Scientific Visualization: Used to graphically

Core Concepts in Parallel Computing
This section addresses fundamental questions regarding parallel systems, architectures, and performance metrics.
Parallel System Components and Models
Which component is not typically considered a fundamental component of a parallel computation system?
Answer: A parallel random-access machine (PRAM) model. (PRAM is a theoretical model, not a physical component.)
Which parallel programming model requires message passing for communication between processes?
Answer: Distributed

System Architecture Fundamentals
Load-Store Architecture
The most common approach in processing is the load-store architecture.
Registers
Registers are tiny local memory (often called “scratch space”) on the processor into which instructions and data are copied.
Memory Management Concepts
Key concepts related to efficient memory utilization:
- Caching: Buffering a copy of bytes (instructions and/or data) from a lower level at a higher level to exploit locality.
- Prefetching: Preemptively retrieving bytes (
Essential Data Structures: Trees, Stacks, and Queues Explained
Tree Data Structure and Terminology
A tree in data structures is a non-linear, hierarchical organization of data elements, called nodes, linked by edges. Trees are used to represent relationships where data is organized in levels.
Here are the key terminologies:
- Node: A basic unit storing data and links to children.
- Root: The topmost node; it has no parent.
- Parent: A node with one or more children.
- Child: A node directly connected below a parent.
- Siblings: Nodes sharing the same parent.
- Leaf: A node with
