Which cloud service model offers fundamental computing, storage, and networking resources on-demand?
💡 Explanation:Infrastructure as a Service (IaaS) is the cloud model that provides the fundamental, virtualized computing resources—servers (compute), storage, and networks—over the internet on an on-demand, pay-as-you-go basis. It gives the user the highest level of control over their operating systems and applications, while the cloud provider manages the physical hardware.

According to Moore’s Law, what characteristic of an integrated circuit doubles approximately every two years?
💡 Explanation:Moore’s Law, an observation by Intel co-founder Gordon Moore, states that the number of transistors on a microchip (Integrated Circuit) roughly doubles every two years. This exponential growth in transistor count has been the driving force behind the corresponding increase in computing power and decrease in cost. The common misconception that performance doubles every 18 months is a *consequence* of this law, but the law itself is specifically about the doubling of the transistor count.

Which phenomenon causes the collapse of a quantum state (qubit) due to interaction with the environment?
💡 Explanation:Quantum Decoherence is the process by which a quantum system, such as a qubit in superposition, loses its coherence (quantum nature) because of uncontrolled interaction with its surrounding environment (e.g., thermal vibrations, stray electromagnetic fields). This is the primary obstacle to developing stable, large-scale quantum computers. Entanglement is a useful quantum property.

What is the defining characteristic of cloud computing services?
💡 Explanation:Cloud computing is defined by the on-demand availability of computer system resources—especially data storage and computing power—delivered over the internet ('the cloud'). This allows users to access resources without direct active management of the underlying infrastructure.

What historical input device originally necessitated the non-alphabetical ‘QWERTY’ key arrangement to prevent mechanical jamming?
💡 Explanation:The QWERTY layout was designed for early mechanical typewriters (specifically by Christopher Latham Sholes) to separate commonly used letter pairings, preventing the physical type bars from colliding and jamming the machine.
