The term "card" in electronics might conjure images of playing cards or credit cards, but in the world of computing, it refers to something far more powerful: expansion cards. These specialized circuit boards, often referred to as add-in cards or daughter boards, are designed to plug into a main board, known as the motherboard, to enhance a computer's capabilities.
Think of it like adding accessories to your car – you can upgrade the sound system, improve braking, or even install a roof rack for extra storage. Similarly, expansion cards allow you to customize your computer's functionality by adding new features, increasing performance, or simply expanding its memory.
Types of Expansion Cards:
The world of expansion cards is diverse, encompassing various functions:
Evolution of Expansion Cards:
Expansion cards have evolved significantly over the years. Early computers relied on proprietary slots and cards, leading to limited compatibility.
