What are the major activates of operating systems with regard to file management?
Creating, deleting, manipluation, backing up file and mapping to permanent storage are the major activities of operating systems with regard to file management.
File basically refers to collection of specific information stored in the memory of computers and file management refers to the process of manipulating these files, such as creating, modifying and deleting files.
Following are the five major activities of all operating systems in regard to file management :
Creating and deleting files: This service creates new files and places them at the particular locations. Also it deletes unnecessary files.Creating and deleting directories: This function helps to store the files in separate folders known as directories that support users to search files quickly. Also deleting files from directories is performed by this activate.File manipulation instructions: It provides functionality to manipulate files and directories, such as modifying the data on files and changing file names in the directories.Mapping to permanent storage: It helps in mapping files onto secondary storage so that the files can be located easily and quickly.Backing up files: This service prevents data loss by providing a backup facility of data on stable and secure storage devices.File management is one of the basic and important functions that all operating systems perform.

Size vs capacity the netvidsdatabase class had two methods called size and capacity. what is the difference between size and capacity?
The NetvidsDatabase class is a data structure that stores information about movies. The size of the NetvidsDatabase represents how many movies are currently in the database, while the capacity represents how many movies can be stored in the database before the underlying array needs to be expanded.
When the NetvidsDatabase is first created, its size and capacity are both set to 0. As movies are added to the database, the size is incremented. If the size reaches the capacity, then the capacity is doubled and the underlying array is expanded to accommodate the new movies.
The NetvidsDatabase class is an efficient way to store and manage information about movies. The size and capacity parameters help to ensure that the underlying array does not need to be frequently expanded, which can save time and resources.

Expressed as a power of two, there are 2^20 megabytes in a terabyte. use a ^ to indicate an exponent, like 2^3 is 2 to the 3rd power.
As anyone who has ever dealt with large amounts of data knows, storage is crucial. And when it comes to storage, size matters. A lot.
That's why it's important to know that a terabyte is equal to 2^20 megabytes. In other words, a terabyte is a whopping 1,048,576 megabytes.
For context, a megabyte is equal to 1,000,000 bytes, so a terabyte is equal to 1,048,576,000,000 bytes. That's a lot of data.
In practical terms, this means that a terabyte can store upwards of 2 million high-resolution photos, or 250 hours of high-definition video.

An office uses an application to assign work to its staff members. The application uses a binary sequence to represent each of 100 staff members. What is the minimum number of bits needed to assign a unique bit sequence to each staff member?.
An office uses an application to assign work to its staff members. The application uses a binary sequence to represent each of 100 staff members. The minimum number of bits required to assign a unique bit sequence is 7.
This means that the office can have up to 2^7, or 128, different staff members. This is a pretty small office, and it's likely that they'll never have more than 100 staff members, so they don't need to worry about running out of space.
This means that each staff member can be assigned a unique work assignment with just 7 bits. This is a very efficient way to assign work, and it ensures that each staff member gets a unique assignment.

To represent 9 different colours, what is the minimum
colour depth needed? Give your answer in bits.
Pls help!!
Answer:
4 bits
Explanation:
3 bits gives you 8 combinations, which is not enough.
4 bits gives you 16 combinations.
n bits gives you 2ⁿ combinations in general.
To represent 9 different colors, the minimum color depth needed is 4 bits.
A bit is the smallest unit of digital information, representing either a 0 or a 1 in binary code.
In computing, bits form the foundation of data storage and processing, enabling the representation of complex information through combinations of 0s and 1s.
To represent "n" different colors, there is a need to find the smallest "k" such that [tex]2^k[/tex] is greater than or equal to "n."
For this case, n = 9 (since there are 9 different colors).
Now, we find the smallest "k" such that [tex]2^k \le 9[/tex]:
[tex]2^k = 2^3 \\[/tex]
= 8 (with 3 bits, we can represent 8 different colors)
[tex]2^4[/tex] = 16 (with 4 bits, we can represent 16 different colors)
Since 4 bits ([tex]2^4[/tex]) is the smallest power of 2 that is greater than or equal to 9, the minimum color depth needed to represent 9 different colors is 4 bits.
