Answer:

C. ATA Secure Erase

D. Smash the USB drive

Explanation:

Zero fill utility is a specialized way of formatting a storage device particularly secondary storage such as hard disk, flash drive e.t.c. In this process, the disk contents are overwritten with zeros. Once this has been done, undoing is essentially hard but possible. In most cases, this might just mean that the data content is corrupt and as such might still be recovered, maybe not in its pure entirety.

Formatting the drive on another hand does not essentially mean cleaning the drive and wiping off data. It just means that operating systems cannot see those data contents anymore. They are still present in the drive and can be recovered.

ATA Secure Erase is actually a way of completely and permanently erasing the content in a drive. Once the function has been done, undoing is not possible. Both the data content and even the data management table will be completely gone.

Smashing the USB drive is the surest way of cleaning data as that will permanently destroy the working components of the drive such as the memory chip. And once that happens then there's no drive let alone its contents.

However, its essential to understand the difference between the RDBMS and the DBMS. The main difference between the two is certainly that in the RDBMS the application stores the data in tabular manner, and DBMS the data is stored as files. In the RDBMS the tables comes with identifier known as primary key, and the data values are being saved in the form of tables.

Charra [1.4K]

Answer:

The delimiter use is "::".

Explanation:

The Java inbuilt String.split( ) function is use to split a String into an array of String.

The split( ) takes delimiter as arguments/parameter which determines at which point the string is to be broken down into different part/token.

From the above code snippet;

Each line in the file a.txt that is not null is splitted using the statement below:

String[ ] v = line.split("::");

The line is splitted using "::" as delimiter and the resulting array is then assigned to the variable 'v'.

For instance, a line in the file could take the form:

John::Smith::Music

When it is splitted,

String lname = John;

because lname make reference to index 0 of the array.

String fname = Smith;

because fname make reference to index 1 of the array.

String dept = Music;

and dept make reference to index 2 of the array.
