1. B
2. D
3. C
4. A
5. B
Explanation:
1. To check the integrity of your hard disk and fix various file system errors, the Windows utility which should be implemented is Check disk (Chkdsk). This utility is always used with the command line interface (CLI) with the command "chkdsk."
2. An event or action took place and it caused damage to data, hardware, software and processing capability of the computer. From the statement given, security risks are being described. Any event or action that is capable of causing a problem to a computer system is considered to be a security risk and should be prevented through the use of an appropriate utility software.
3. Virus is a software program that can infect, damage and disrupts the whole computer system.
4. To protect the whole computer system, the software utility which is needed is an Anti-virus.
5. To avoid losing valuable data to your computer, the most important thing to do is to regularly back-up your files.
Public int setLimit(parameter) {
if (parameter > 10) {
return 10;
} else {
return parameter;
}
}
A data structure called a binary search tree makes it simple to keep track of a sorted list of numbers.
<h3>What is a binary search tree?</h3>
A binary search tree, also known as an ordered binary tree or a sorted binary tree in computer science, is a rooted binary tree data structure where each internal node's key is higher than all the keys in its left subtree and less than all the keys in its right subtree.
A data structure called a binary search tree makes it simple to keep track of a sorted list of numbers. Because each tree node has a maximum of two offspring, it is known as a binary tree. It can be used to search for the presence of a number in O(log(n)) time.
A binary search tree (BST) is a specific type of binary tree in which every node has a comparable key and a connected or associated value.

Answer:
B. Symmetric key encryption
Explanation:
Symmetric key encryption is one in which a single encryption key is sent to the receiver so both sender and receiver share the same key. In this type of encryption, the sender uses a particular key to encrypt the data and sends the encrypted data (cipher data) to the receiver and then the receiver uses the same key to decrypt the data.
Public key encryption, or asymmetric encryption uses two keys - a private key and a public key. The public key is know to everyone while the private key is known only to those for whom the message is intended. An application of this type of encryption is in SSL (Secure Sockets Layer) - a protocol for transmitting data privately on the internet.
Private key encryption is not exactly one of the encryption methods but rather, a private key and a public key are used in encryption.
The best option is therefore <em>symmetric key encryption</em>.
