Answer:
The features that required to protect the privacy should be:
- Protection of User name and Password
- Protection of Finger print and other bio metric information if collected from user.
- Protection of Personnel Information such as contact information, Identity information if collected.
- Protection of data shared such as pictures and videos.
Explanation:
Privacy protection is required to different websites that are involved in collection of different information from users such as user name, password, contact information, account information and messengers. These websites could be website of some bank, online mailing platforms, online shopping platform and social media platforms. These all are used to share and gather our personnel information for different purposes. To ensure the protection of user data they signed a document with users at the time of making account.
The above mentioned are the features that should be included in privacy protection of the website. As all mentioned features are personnel for every user and should be protected from hackers.
First, rpm is RedHat Package Manager. Compilation is done with gcc, the GNU C Compiler.
To add that kernel to grub2's menu, as root you'd need to run:
grub2-mkconfig > /boot/grub2/grub.cfg #redirection is favored by Red Hat
Check out the man page @ man grub2-mkconfig
Answer:
Implicit type casting means the type casting done by the compiler during compilation of program whereas Explicit type casting means the programmer explicitly type casts the variables. This is the difference implicit and explicit type casting.
Explanation:
Type casting means the conversion of one data type into another data type. There are two types of type casting. They are Implicit type casting and Explicit type casting.
<u>Implicit type casting:</u> The type casting which is done by the compiler during the compilation of a program. This occurs when we assigning smaller data type to larger data type and also both the data type are compatible. Below example clears the above concepts.
Ex:

In the above example " i " is " int " data type whereas " l " is long data type but as we assigned the value of " i " to " l ". Here " int " and " long " are compatible data types and we assigned smaller data type ( int - i ) to larger data type ( long - l ) implicit type casting occurs.
<u>Explicit type casting:</u> The type casting which is done by the programmer explicitly to convert one data type into other data type. If we want to assign a value of larger data type to smaller data type explicit type casting is required. Below example clears the above concepts.
Ex: 

In the above example " d " is " double " data type whereas " l " is " long " data type. Here we are explicitly type casting to change larger data value ( double - d ) to smaller data value ( long - l ).
You would want to check for any programs running in the background, as well as run a virus scan.
