It's an output device, think about it, it's outputting something - aka your image onto paper.

Input is the opposite, it inputs something onto into the computer, for example a scanner would be an input device.

Answer:

Check the explanation

Explanation:

CPU utilization and response time: CPU utilization is amplified if the overheads that are connected with context switching or alternating are minimized. The context switching outlay can be reduced by performing context switches occasionally. This could on the other hand lead to increasing the response time for processes.
The Average turnaround time and maximum waiting time: Average turnaround time is reduced by implementing the shortest or simple tasks first. Such a scheduling and arrangement strategy could nevertheless starve long-running tasks and in so doing boost their overall waiting time.
I/O device utilization and CPU utilization: CPU utilization is maximized by executing a list of long-running CPU-bound tasks not including the performing context switches. This is maximized by setting up I/O-bound tasks as early as they become ready to run, thus sustaining the overheads of context switches.

Answer:

An online company wants to conduct real-time sentiment analysis about its products from its social media channels using SQL. The solution which has lowest cost and operational burden is as follow:

B. Configure the input stream using Amazon Kinesis Data Streams. Use Amazon Kinesis Data Analytics to write SQL queries against the stream.

Explanation:

The option A is not correct as this solution doesn't have lowest cost and operational burden as set up a streaming data ingestion application on Amazon EC2 and connect it to a Hadoop cluster for data processing will have more cost and operational burden.
The lowest cost and operational burden solution is that we configure input stream using Amazon Kinesis Data Streams. We can use Amazon Kinesis Data Analytics to write SQL queries against the stream.
The option c and d are also more pricey in terms of cost and operational burden as compared to Amazon Kinesis Data stream and analytics.
