Fundamentals of Computer Science

Computer science is the study of computational systems and computers. It covers

theory, development, and application of software and systems that solve problems or

perform tasks.

Programming is a core component, with languages such as Python, Java, and C++ used

to write instructions for machines. Algorithms, which are step-by-step procedures for

calculations, are fundamental to computer science.

Data structures such as arrays, linked lists, stacks, queues, and trees organize and

manage data efficiently. Understanding how to use and implement these is essential for

effective programming.

Databases store and manage data in structured formats. SQL is the most commonly

used language for database queries. Data integrity, security, and normalization are key

concerns.

Computer networks allow devices to communicate. Concepts include IP addressing,

protocols (like TCP/IP), and network topologies. The internet is a global network that has

transformed communication and commerce.

Cybersecurity focuses on protecting systems from threats like viruses, malware, and

hackers. Techniques include encryption, firewalls, and multi-factor authentication.

Emerging areas include artificial intelligence, machine learning, cloud computing, and

quantum computing. These technologies are reshaping industries and creating new

opportunities.
