    • Storage Devices: Hard Drives, Solid State Drives, and other forms of storage are critical for saving data and software.
    At the core of this field is a principle known as Moores Law. This observation by Gordon Moore, co-founder of Intel, notes that the number of transistors (or fundamental on/off switches in a processor) that can fit onto a piece of silicon doubles approximately every two years. This principle can be mathematically represented as: \[ N = N_0 \times 2^{(t/2)} \] where \(N\) represents the number of transistors after a certain time \(t\) years, and \(N_0\) is the initial number of transistors. Physically realised in silicon chips, this principle drives a consistent growth in computing power, enabling ever-more complex tasks to be handled by digital systems.

    A microprocessor that initially has 2 million transistors are designed with more complex and powerful updates. After 4 years, per Moores Law, the number of transistors on these chips can be expected to have doubled twice: \( N = 2,000,000 \times 2^{(4/2)} = 8,000,000 \) transistors.

    An essential part of digital logic is the 'Boolean Algebra'. Boolean Algebra is an algebraic structure defined on a set of binary variables to perform logical operations - usually denoted as \(AND\), \(OR\) and \(NOT\).
    // C++ code to demonstrate AND operation
    bool a = true, b = false; 
    cout<< (a && b) <

    Microprocessor Design: This aspect empowers you to understand, design, and optimise processors or CPUs. Central subjects include microarchitecture, instruction set design, and optimising for power, performance and cost.

    VHDL/Verilog: These are hardware description languages. Learning them will enable you to design and simulate digital systems at a high level, from custom logic circuits to complete CPUs.

    // Sample Verilog code to define a basic digital circuit – an AND gate
