Answer:
b. Redundant hardware and data backup systems
Explanation:
Data privacy is important where a company collects, processes and stores personal information.In the US-EU have laid down regulations to ensure data privacy is maintained. It is a requirement before collection of personal data, to clearly state why the data is being collected and how it will be used.The individuals whose data is being processed have a right to access their data at no cost during processing . Of great importance is the security of the data so as to maintain its integrity, Companies are required to take steps in protecting the data from unauthorized access, processing and accidental loss.redundant hardware and data backup system are used by companies as a fail-safe mechanism in data protection but they are not a requirement in data privacy, although they enhance it.
Answer:
mkdir homeworks // make a new directory called homeworks.
touch homework_instructions.txt //create a file called homework_instruction
sudo -i // login as root user with password.
chmod u+rwx homework_instructions.txt // allow user access all permissions
chmod go-wx homework_instructions.txt // remove write and execute permissions for group and others if present
chmod go+r homework_instructions.txt // adds read permission to group and others if absent.
grep POINTS homework_instructions.txt | ls -n
Explanation:
The Linux commands above first create a directory and create and save the homework_instructions.txt file in it. The sudo or su command is used to login as a root user to the system to access administrative privileges.
The user permission is configured to read, write and execute the text file while the group and others are only configured to read the file.
Answer:
Maximum Aggregate I/O Transfer Rate = 1630kb/s
Explanation:
Given
Transfer rate of
Disk Drive = 800Kb/s
DVD Drive = 700Kb/s
Printer = 10Kb/s
VDT = 2Kb/s
Units
DVD = 2
Hard Disk = 2
Printers = 2
VDT Channels = 5
Only one device at a time can be serviced on a selector channel
Both cannot be active at a time
So, the device with higher transfer rate will be granted access (Disk Drive, 800Kb/s)
Maximum aggregate I/O transfer rate in this system is calculated by:
Summation of transfer rate of each device
= 800 * 2 + 2 * 10 + 5 * 2
= 1600 + 20 + 10
= 1630kb/s
Both logical AND and logical OR operators evaluate a given condition and return either true or false.
The logical AND operator returns true only when both the given conditions are evaluated to be true. For instance, c<em>ondition (10 > 5 AND 8 > 4) returns true because both the conditions with AND operator are true.</em> Now suppose the given condition is <em>(10 > 12 AND 8 > 4), it returns false because 10 is not greater than 12</em>. The AND operator returns true only when both the conditions are true; if any or both are false, false is returned.
The logical OR operator return true when either of the two conditions is true. For example, <em>the condition is (10 < 5 OR 8 > 4); it returns true because one condition is true which is 8 is greater than false</em>. It means the logical OR operator returns true if both or any of the given conditions are evaluated to be true. In case both the conditions are false in an OR statement then false is returned such as<em> (10 < 5 AND 8 < 4) returns false</em>.

Answer:
Information technology department is related with all the information retrieving, storing ,processing etc through a system .Information security department is responsible for protection of information from unauthorized access.
For maintaining the collaboration and proper functioning of both the department should report to the same head of the department .In this way, they can stay updated, secured, assisted togather and help each other as both departments are working for the information field.
Separate reporting of the both departments to different head can create confusion,risk of security, dysfunctional working,other risks as well.Thus, both departments should report to same head of department .
