System Design

The building blocks of modern system design are often referred to as the "three pillars" of computer science: data, algorithms, and software. These three components work together to enable the creation of complex, scalable, and reliable systems that can solve a wide variety of problems and meet a wide range of requirements.

1. Data is the raw information that a system processes and manipulates. This can include structured data such as numbers, texts, or dates, as well as unstructured data such as images, audio, or video. Data is typically stored in a database or data structure, and can be accessed and modified using various data management techniques and tools.

2. Algorithms are the sets of steps or procedures that a system follows to manipulate and analyze data. These can range from simple mathematical operations to complex machine learning models, and can be used to solve a wide range of problems such as sorting, searching, optimization, or prediction. Algorithms are typically implemented in a programming language and can be executed by a computer or other device.

3. Software is the collection of instructions and routines that a system uses to manage its hardware and resources, interact with users, and execute algorithms and other tasks. This can include operating systems, libraries, frameworks, and applications, as well as the interfaces and protocols that enable communication and collaboration between different components and systems. Software is typically developed and maintained by teams of programmers using various software development tools and methodologies.

Together, these three pillars form the foundation of modern system design and enable the creation of complex and powerful systems that can handle large amounts of data, solve complex problems, and meet the evolving needs and requirements of users and stakeholders.
