Answer: b. actuator
Explanation:
We know that a RW head ( or also known as read/write head) is a component of device which is usually appeared on the hard drive which is used to read and write data by the hard drive's disk . When data required to be read or write, the read/write arm is regulated by actuator.
[An actuator is a part of a device that is mainly responsible for moving and controlling a mechanism or system.]
Hence, All the read/write heads a hard disk are controlled by an actuator .
Natural ventilation in a space, such as a room, means that air flows in and out without the use of artificial mechanisms (such as fans and air conditioners) that provide and generate air for respiration, breathing, and cooling purposes by the use of windows and doors for cross-ventilation.
What is Natural Ventilation?
Why do managers encourage people to use Natural Ventilation techniques? According to international estimates from the US Office of Technology Assessment, developing countries have the potential to reduce their electricity generation if energy is used more efficiently.
One of these methods is ventilation, particularly natural ventilation. It is a method of introducing fresh air into a home or office space by utilizing passive forces, typically wind velocity or pressure differences both externally and internally.
Natural ventilation refers to the movement of air between the outside and inside of a structure. Natural ventilation is caused by two natural forces: pressure variations caused by wind blowing around the building (wind-driven ventilation) and temperature variations ('stack effect' ventilation).
Natural ventilation is required when using HVAC products. Natural Ventilation systems are available from a wide range of Suppliers and Companies, as well as manufacturers and distributors, and Linquip has a large selection of Natural Ventilation systems for sale.
