Answer:
Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems. The first part of the formatting process that performs basic medium preparation is often referred to as "low-level formatting".[1] Partitioning is the common term for the second part of the process, making the data storage device visible to an operating system.[1] The third part of the process, usually termed "high-level formatting" most often refers to the process of generating a new file system.[1] In some operating systems all or parts of these three processes can be combined or repeated at different levels[3] and the term "format" is understood to mean an operation in which a new disk medium is fully prepared to store files. Some formatting utilities allow distinguishing between a quick format, which does not erase all existing data and a long option that does erase all existing data.
As a general rule,[nb 1] formatting a disk by default leaves most if not all existing data on the disk medium; some or most of which might be recoverable with privileged[nb 2] or special tools.[4] Special tools can remove user data by a single overwrite of all files and free space.[5]

Answer:
d. Internet Protocol
Explanation:
Internet Protocols suite are used to transport packets from the host network across other networks. This task is usually performed by optimizing the size of each available packet, which are then forwarded through the internet protocol (IP) address.
Therefore, Internet Protocol is responsible for packet forwarding.
False. As it is common knowledge, it is unnecessary for it to be documented.
Answer:
C. Lists involve data with multiple themes
Explanation:
<em>First of all, it will be beneficial to explain all the concepts involved.</em>
<em />
A spreadsheet is an electronic ledger in which data is arranged in rows and columns of a grid and can be manipulated and used in calculations.
A database can be defined as a structured set of data held in a computer, especially one that is accessible in various ways.
A theme in data storage refers to the subject matter or topic that categorizes various data sets.
A spreadsheet can be used to store and analyse simple data sets as shown in the options A, B and D. However for option C, a database must be used if it needs to be done accurately.
A data base is more robust than a spreadsheet and can accommodate a lot more diversities in the data sets.
Spreadsheets are built to simplify data analysis, and have their candid limitations - they cannot assure data integrity or consistency when dealing with data of various subject matters.
Lists that involve data with multiple themes can be easily handled with data bases, because data bases specialize in collecting raw data in a tabular form which cannot be formatted. This helps sort out the data into their various themes.
The tables on a database can be programmed to accept a particular theme of data, and nothing else. however, this cannot be done with spreadsheets, as the cells accept the data first before it is formatted to the data type it is. Thus databases help ensure consistency and integrity of the data when dealing with data of multiple themes
