inn [45]

Answer:

"Deadlock" is the right solution.

Explanation:

  • A deadlock seems to be a circumstance where certain (two) computer algorithms that share a similar resource essentially prohibit each other during manipulating the asset, leading to both programs withdrawing to operate.
  • This occurs when multiple transfers or transactions block everyone by maintaining locks onto assets that every other activity also needs.

So that the above is the correct answer.

List the five parts of a system.describe them.
dem82 [27]
The five main parts of a system are: 

1. The CPU
The CPU is the brain of the computer. It is the main part that does all th thinking and processing.

2. RAM
which stands for Random Access Memory. As implied in its name, it can be accessed at random times by the CPU. When you open a program, all the scripts and codes that are running need to be run of a separate memory bank. Thus, the RAM takes part.

3. Drives
Hard Drives, SSDs, USB Drives, and SD cards are all forms of main computer memory. That is where the computer stores the OS, your files, and its instructions.

4. Inputs/Outputs
By inputs and outputs i mean hardware, like Speakers (ouput), Monitors (output), Keyboard (input), and Mouse (input).

5. OS
The OS is the Operating System (e.g. Windows, Linux, Mac), which is the main instructions for the computer. It is what makes your computer usable.

wolverine [178]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

Betty is developing a machine learning algorithm that looks at a vast amount of data that is collected over 100 years, and She also wants to check the relationship among variables such as humidity, temperature, and rainfall in the given data.

So, the correct answer to this question is b. She is developing an association machine learning algorithm.

Because the association tells the relationship between variables. She used the association to find the relationship among variables such as humidity, temperature,  and rainfall.

While the other options are not correct because:

Regression is used to find out the cause and effect relationship between dependent and independent variables. Big data is the biggest field of data analysis, so this option does not best suit this context. Classification is used to classify data, or organizing data into their related group. While clustering is the task of dividing the population into a number of groups such that populations in the same groups are more similar to other populations in the same group than those in other groups. so these are all incorrect options to this question except the "b" option i.e association.
