Explanation:
Two ways an electronic record may be distributed are e-mail or printing and publishing to others.
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.

Group of answer choices.
a. firewalls
b. access controls
c. proxy servers
d. All of the above
Answer:
d. All of the above
Explanation:
Cyber security can be defined as a preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Generally, redundancy to prevent unauthorized access can be implemented at a number of points throughout the security architecture, such as in firewalls, proxy servers and access controls.
A firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.
Generally, a firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access. It is a security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer.
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device.
On single and double overhead cam engines, the cams are driven by the crankshaft, via either a belt or chain called the timing belt or timing chain. These belts and chains need to be replaced or adjusted at regular intervals.
Answer and Explanation:
Pros of cleanroom software
- This helps in confirming the plan detail with the assistance of mathematically based evidence of rightness.
- This uses incremental development processes.
- This uses incremental development processes.
- The realistic expectation is considered as less than 5 failures per KLOC on the first program execution in the project.
- There are short advancement cycles and longer item life.
Cons of cleanroom software
- This exceptionally relies upon the statistical utilization of testing for revealing the high impact mistakes.
- The software is also not compiled or executed during the verification process hence it would become difficult to find the errors.
