Loogikaahelad, also known as logic gates, are fundamental building blocks of digital circuits. They perform basic logical operations on one or more binary inputs to produce a single binary output. These operations are based on Boolean algebra, where inputs and outputs are represented by two states: true (1) or false (0).

The most common logic gates include AND, OR, NOT, NAND, NOR, XOR, and XNOR. An AND gate outputs true only if all its inputs are true. An OR gate outputs true if at least one of its inputs is true. A NOT gate, also known as an inverter, outputs the opposite of its single input. NAND gates perform the inverse of an AND operation, and NOR gates perform the inverse of an OR operation. XOR gates output true if an odd number of inputs are true, and XNOR gates output true if an even number of inputs are true.

These simple gates can be combined in complex arrangements to create more sophisticated circuits, such as adders, multiplexers, decoders, and memory elements. Ultimately, the combination of these logic gates forms the basis of all digital systems, from simple calculators to advanced microprocessors and computers. Understanding logic gates is crucial for anyone studying digital electronics or computer architecture.
