<span>In general you want to use the cheapest storage medium who's speed is compatible with the function it needs to perform. For active storage that's handled while running programs, you need memory whose speed is closely matched to the processor speed. And that would be the rather expensive semiconductor memory which is close to ideal for the task. But semiconductor memory has the disadvantage of being expensive and it loses the values stored when power is lost. So slower, persistent storage is used such as SSD (Solid State Drives) and hard disks. That media is cheaper, but slower, but still fast enough to handle tasks such as loading programs and data into memory for execution, or storing data generated by programs to persistent storage. But as with all man made things, disasters happen. Computers break down, hard disks crash, floods and fires happen, etc., and as a result data is lost. So we make backups. Backups have to have a lot of storage and they have to be cheap. But they don't need rapid access, you can start at the beginning and read (or write) all the way to the end. And for that purpose, magnetic tape is ideal. Magnetic tape is actually quite fast when you're simply streaming a continuous stream of data without any need to randomly access any piece of that data. And it's cheap, so you're willing to make a back up copy of your system and store that backup off site so a single disaster won't destroy both the primary system and the backup.</span>
Answer:
to compose letters and memos
to create charts and graphs from a table of
values
to deliver a sales presentation to clients
Explanation:
I forget what the reasoning behind them but I know this is the answer
Answer:
Option A - They are responsible for writing programming
Option B - They are usually strong problem-solvers
Explanation:
A software engineer needs to be a strong problem solver and he/she must be able to write program/code. He/She is not required to conduct experiments in labs and also it is not essential for them to hold masters degree as even the non computer science or IT background people are working as software engineer.
Hence, both option A and B are correct
Answer:
The answer is "Option A".
Explanation:
In the given question the method toString() is used that converts any value into a string. In this code two print method is used, that can be described as follows:
- In the first method, object1 is created, which is used to print all object values.
- In the second method, object1 uses the toString() method, which converts all values into a string, that's why the answer to this question is "True".
