In formal language theory and computational complexity decidable languages play a crucial role in understanding the limits of computation. A language is decidable if there exists a Turing machine that can determine in finite time whether a given string belongs to the language or not. One fundamental property of decidable languages is that their union …

Functional dependency is a fundamental concept in Database Management Systems (DBMS) that plays a crucial role in database design and normalization. Understanding functional dependency helps in structuring relational databases efficiently to reduce redundancy and maintain data integrity. This topic answers the most commonly asked questions about functional dependency in DBMS explaining its importance types and …

The fetch-decode-execute cycle is the fundamental process that a Central Processing Unit (CPU) follows to execute instructions. Every operation that a computer performs—whether running software browsing the internet or playing a game—depends on this cycle. In this topic we will break down the fetch decode and execute steps explain their role in processing instructions and …

Computers are designed to process data efficiently and one of their essential functions is performing calculations and comparisons. Whether solving complex equations executing commands or making logical decisions computers rely on specific components to handle these operations. The part of the computer responsible for calculating and comparing is primarily the Arithmetic Logic Unit (ALU) a …
