The two major SAS steps are data and proc.
SAS programming structure is based on two essential steps, Data and Proc.
1. The DATA step:
This involves collecting and uploading the essential data to the program memory. It is used to update, modify and edit the data in case of any errors once it has been added to a dataset. New datasets can be created from existing ones by updating, editing, and/or merging them. at the end of this step, SAS data sets are created.
2. The PROC step:
This step processes and analyses the data collected into datasets in the previous step. it is used to perform specific functions on the data. at the end of the proc step, a result or report is produced.
In a SAS code, each line of code should begin either with a DATA or PROC step.
<u>While the other options are incorrect because: </u>
<u />
- Analysis: analysis is done in the PROC step.
- Content: Data or content is collected in the DATA step.
- Stat: a stat function acquires the status information regarding a specific file. Functions are performed on the datasets in the PROC step.
- Run: This command is used to execute a code.
- Import: Datasets are created by importing data from other datasets and outside.
- Print: the report produced at the end of the PROC step can be printed as a hard copy.

Answer:
Distributed computing
.
Explanation:
Distributed computing is a concept of computing under which many system types become connected together to exchange information and resources.
It should enable the software to utilize processing capacity, storage, or resources on another system on individual machines. In simple words, it is restricted to software with resources exchanged within a specific geographical region between systems.
Several of eap protocols use encryption function, which creates a ciphertext from cleartext.

Answer:
The description of the given points can be described as follows:
Explanation:
A hash table is a specific array, which is used to contain items of key value. It uses a hash to calculate an index of an array, which inserts an item, and the given point can be described as follows:
- In option a, It includes several duplicates, which is a large number of unavailable tanks, although there is a large overflow list for the used tanks.
- In option b, multiple copies are painful to scan because we have to read and understand rather than a single line.
- In option c, It can break frequently, if there are several exact copies.
