Answer:

a. True

Explanation:

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

In Linux, users are internally represented using a unique number called user ID or UID. Thus, this unique number serves as an internal identifier in the Linux Kernel and as such determines what system resources may be accessible to each user. Oftentimes, these unique numbers are not put into use but rather a name is linked with the number and are used instead.

Also, users can be organized logically into a group and are represented uniquely with a group ID or GID, which serves as a global identifier for the users.

A majority of the people whose information was compromised are homeless; therefore there is no easy way to contact them in order

Incomplete question. Here's the full question:

Data-Time Inc. is a company that manages databases for a large city in Colorado. Included in these databases is information collected from the city’s homeless shelters and free clinics. Specifically, the databases contain personal information of the users of these services over the past 10 years; this includes people’s Social Security numbers and health records.

This data is highly secure and only accessible to the employees of Data-Time Inc. Employees are given a laptop when they are hired which allows them to access the database remotely. Unfortunately, one of these laptops is stolen and the security of the database is compromised.

A majority of the people whose information was compromised are homeless; therefore there is no easy way to contact them in order to alert them of the security breach. How should Data-Time Inc. manage this breach in security?

<u>Explanation:</u>

Since the emphasis is not on reversing the breach that has occurred, but on managing the level of security damage that could occur, it is important measures are directed towards preventing unauthorized access to sensitive information.

For example, the Media Access Control Address (MAC address) of the laptop if known could be greylisted from accessing the server that contains the sensitive information.
