Hard Disk Drive (HDD) vs. Solid State Drive (SSD) | IBM

The speed at which an SSD accesses data is higher than an HDD speed. While an HDD can process 500 MB/s, most SSDs can process at 7000 MB/s. These faster speeds allow for instantaneous startup and less latency when logging in to a device or load times on apps. Also, file transferring and copying are faster on an SSD.

Energy storage

OverviewHistoryMethodsApplicationsUse casesCapacityEconomicsResearch

Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Ene…

Electromagnetic radiation | Spectrum, Examples, & Types

In terms of the modern quantum theory, electromagnetic radiation is the flow of photons (also called light quanta) through space. Photons are packets of energy h ν that always move with the universal speed of light. The symbol h is Planck''s constant, while the value of ν is the same as that of the frequency of the electromagnetic wave of ...
