In the construction process for solid-state flash memory drives (thumb drives), nearly all drives are constructed with a large potential amount of storage space, and are sold base on the actual amount of memory that forms correctly during the process (For example, drives that are designed to store 64 gb but contain a large number of bad sectors will instead be formated and sold as 32 gb). Consider a manufacturing process where every chip has a 21% of having enough bad sectors to be downgraded, and these errors are random and independent.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
