HISTORY: Integrated Circuits

A

AKA microchip. integrates multiple electronic components, like transistors, resistors, and capacitors, onto a single semiconductor chip, typically silicon. Smaller, faster and less expensive than those constructed of discrete components. This allowed computers to have a much larger transistor count.

TREND: Quantum computing

A

Potential to solve problems much faster than classical computing. This can lead to breakthroughs in medicine and science. They are very expensive to develop and maintain. Their speed and power could also lead to modern encryption methods becoming obsolete, posing a significant risk to privacy and security.

Q

TREND: Blockchain

A

Offers decentralized and transparent way to record transactions, enhances trust in finance, supply chains and voting systems since there is no single point of control. Enhanced security because once information is entered on blockchain it is extremely difficult to alter.
Privacy concern for some as all transactions recorded and are able to be traced back to them.
Environmental conerns since they require substantial energy consumption for mining and validating transactions
