It is important to give the health and safety experience to new or inexperienced workers, including those that have been away fr
Phoenix [80]

Answer:

a. training

Explanation:

"Training" is crucial when it comes to new workers or workers who are coming back after a long vacation or whatever reason. The risk of injuries and making mistakes is high for new workers because they are still adjusting to the company's processes. This is similar to a baby who's learning to walk. The baby makes several slips before mastering the skill. For a worker who has been away from the workforce, training should also be given because that worker needs to freshen up his skills and relearn what he needs to grasp before working.

This situation is especially true to <em>construction workers </em>who work under contractual projects. This means, they always have to be trained every time about their new jobsite before even working.

What is the capacity of a disk with two platters, 10,000 cylinders, an average of 400 sectors per track, and 512 bytes per secto
natita [175]

Answer:

The capacity of the disk is "40 GB".

Explanation:

Given value:

\to \text{cylinder}= 10,000\\\\\to \frac{sector}{track} = 400\\\\\to \frac{bytes}{sector} = 512\\

\text{Calculating the size of track} =  \frac{bytes}{sector} \times  \frac{sector}{track}

                                            = 512 \times  400 \\\\ = 204,800 \ \ Or  \ \ 200 \ K

\text{Calculating the size of surface} = \frac{byte}{track} \times \ cylinder

                                               = 2000 \ K \times  10,000 \\\\ = 20, 000,000 \ K

\text{Calculating the capacity of a disk} = \frac{byte}{surface} \times \frac{surface}{disk}

                                                     = 20, 000,000 \ K \times  2 \\\\ = 40, 000,000 \ K \\\\= 40 \ GB

Cache memory is often used to speed up the runtime. It will enable us to improve performance unless we can store information, that is retrieved constantly in memory space.

  • Hit Cache: when the Processor relates to representing database data, Cache Hit results.
  • Miss Cache: when this Processor responds to a non-present cache data, this will trigger its miss of cache.
  • It doesn't have to retrieve the Main Memory through secondary storage.
