Answer:
Security Policies
Explanation:
As computer systems continue to become complex, it makes it hard for co-operates and big businesses to understand the technology that comes with it. Organizations are concerned with how risks are being handled, managed, and reduced. They therefore, expect security policies to reflect how information should be handled. Better security policies shows a company's commitment to protect data and keep the business healthy.

Technician A says that oil for the rod bearings comes from splash off the crankshaft. Technician B says that lubrication to the main bearings is fed through the main oil gallery in the block. Who is correct?
Answer: technician B
Explanation:
The oil is picked up from the oil pump though a pick up tube that is mounted on the oil pump. The end of the pick up tube sits in the oil at the bottom of the oil pan. The oil is then forced through holes that are drilled into the block. Those holes which are called (journals) lead to the main bearings,rod bearings,lifters, camshaft, ect..
Technician B says that lubrication to the main bearings is fed through the main oil gallery in the block is correct.
How are the main bearings lubricated?Lubrication regimes
Engine bearings are lubricated by motor oils constantly supplied in sufficient amounts to the bearings surfaces. Lubricated friction is characterized by the presence of a thin film of the pressurized lubricant (squeeze film) between the surfaces of the bearing and the journal.
Which lubricant is used for bearing?A lithium-based grease, whose base oil is mineral oil, is commonly used as a lubricant for rolling bearings, as it is compatible with the working surface of the bearing. Its operating temperature range is -30˚C to 130˚C.

Which of the following refers to a technology with a three-dimensional computer simulation in which a person actively and physically participates? A. Wireless fidelity*B. Virtual realityC. Augmented realityD. Agile methodology
Answer:
B. Virtual reality
Explanation:
In a virtual reality context, the visual and auditory senses of the user are fed by data (images, sounds) from the computer using a goggle and earphones. That allows the person to be totally cut off her real physical environment and be totally immersed into the world (reality) managed by the computer.
Not to be confused with augmented reality, where the physical reality and perception of it aren't changed... but an additional layer of information is added on top of it. Like pointing your phone camera to a building and getting information about the building displayed on your phone.

. Write a function wordscramble that will receive a word in a string as an input argument. It will then randomly scramble the letters and return the result. Here is an example of calling the function: >> wordscramble('fantastic') ans = safntcait
Answer: You can use the function randperm() to generate a random permutation of the indexes. so then you would use the random permutation to reorder the string array
Explanation:
Write a Java program that reads an 8-bit binary number from the keyboard as a string and then converts it into decimal. For example, if the input is “01001101”, the output should be “77”. (Hint: Break the string into substrings and then convert each substring to a value for a single bit (i.e., 0 or 1). If the bits from right to left are b0, b1, …, b7; the decimal equivalent value is b0 + 2b1 + 4b2 + 8b3 + 16b4 + 32b5 +64b6 + 128b7.
Answer:
public class Brainly
{
public static void main(String[] args)
{
BinaryConverter conv = new BinaryConverter();
String binStr = "01001101";
System.out.print(binStr + " in decimal is "+conv.BinToDec(binStr));
}
}
public class BinaryConverter
{
public int BinToDec(String binStr)
{
int d = 0;
while(binStr.length() > 0)
{
d = (d << 1) + ((binStr.charAt(0) == '1') ? 1: 0);
binStr = binStr.substring(1);
}
return d;
}
}
Explanation:
The program "eats" the string from left to right, and builds up the integer representation in variable "d" on the go. While there are digits left, it shifts the previous result to the left and sets the least signficant bit to 1 only if the corresponding string character is a 1.
1. Suppose a process in Host C has a UDP socket with port number 6789. Sup- pose both Host A and Host B each send a UDP segment to Host C with destination port number 6789. Will both of these segments be directed to the same socket at Host C? If so, how will the process at Host C know that these two segments originated from two different hosts?
Yes. Host A and B have the same destination port numbers and thus, their UDP segments will arrive to the socket at host C. In this case, the UDP sockets are represented by the protocol IP and Port. Host C will be able to differentiate between them by doing a check on the source IP and source port from the UDP header.
Both UDP segments sent by Host A and Host B to Host C's port number 6789 will be directed to the same socket. Host C differentiates them based on their source IP addresses and source port numbers.
Explanation:If a process in Host C has a UDP socket with port number 6789, and both Host A and Host B send a UDP segment to Host C with destination port number 6789, both of these segments will indeed be directed to the same socket at Host C. This is because the port number serves as an identifier for incoming data traffic, ensuring that data is sent to the correct receiving application process.
Although both segments are directed to the same socket, the process at Host C can distinguish between the two segments because each UDP segment contains not only the destination port number but also the source IP address and the source port number from which it originated. These details provide enough information for the receiving process to differentiate between segments from Host A and Host B. In the analogy of an apartment building, where the port number would be the apartment number, the source IP address and source port number are analogous to the return address on a piece of mail. The combination of these uniquely identifies each sender.
You are the network administrator for Slimjim, a peripheral device company. The network uses Linux, and you need information on some commands to perform your job. Open the manual pages and find all the commands that have the word "copy" in their name or description. What command did you use to accomplish this task? Are there any commands in this list that only a root user can execute? How are they indicated? Select any two of them and compare their info and manual pages. Access and read the manual pages on three other commands that interest you either by using the command name or searching for them by related keyword (try using apropos).
Step 1 of 4
What command did you use to accomplish this task?
First of all, let us ask ourselves what manual pages or man pages are. Manual pages in Unix/Linux are sometimes referred to as an online form of software documentation. They are a set of pages that try to explain and expound every command available on your system. Further, these pages explain to you the specifics of what each command does and how to run them. And in this case, we can use two commands to search for all the commands that have the word "copy" in their name or description. The commands are “man –k copy” or “apropos copy”
Step 2 of 4
Are there any commands in this list that only a root user can execute? How are they indicated?
Yes. There are several commands in this list that only a root user can execute. If you would want to find out what these commands are, the best way to do that is to look at those manual pages that are indicated by the manual page section number. If it has a number 8, then a root user can execute this command
Let’s compare the cp command and the cpio command
If you do an apropos or a man page on the commands above, you will spot a few differences. The cp command is used to copy files and directories from source to target location while the cpio command copies files to and from archives. The available options are –a –b –d –f –i –l –L –p and several others. On the other hand, the available options for cpio are –0 –a –A –b –B –C –c –d –E and more.
Access and read the manual pages on three other commands that interest you either by using the command name or searching for them by related keyword (try using apropos)

SYNOPSIS
cifsdd [OPERAND]...
cifsdd OPTION
DESCRIPTION
This tool is part of the samba(7) suite.
Copy a file, converting and formatting according to the operands.
bs=BYTES
read and write up to BYTES bytes at a time (default: 4096)
ibs=BYTES
read up to BYTES bytes at a time (default: 4096)
obs=BYTES
write BYTES bytes at a time (default: 4096)
To find all the commands that have the word "copy" in their name or description, I would use the `man` command with the `-k` option, which is a synonym for `apropos`. The command would be:
man -k copy
This command will search the manual pages for any commands that match the keyword "copy" in their name or description.
Regarding commands that only a root user can execute, they are typically indicated by the presence of "(8)" at the beginning of their manual page descriptions. For example, if a command is only executable by the root user, its manual page description might start with "(8) -". The number 8 indicates that it is a system administration command.
As for comparing the info and manual pages of two commands, let's consider the `cp` and `scp` commands:
1. cp (1):
Info Page: Provides detailed information on how to use the `cp` command, including its syntax, options, and examples.Manual Page: Offers a concise summary of the `cp` command, its usage, and available options.2. scp (1):
Info Page: Gives an overview of the `scp` command, its usage, and options, along with examples and related concepts.Manual Page: Provides detailed information on the `scp` command, including its syntax, options, and usage scenarios.For the remaining three commands, I will choose `rsync`, `mv`, and `tar`. Let's access and read their manual pages:
man rsync
man mv
man tar
These commands are often used for file and directory manipulation, backups, and archiving, which are essential tasks for a network administrator.
. True or false: Customers who conduct online banking on their laptops or personal computers must use Hypertext Transfer Protocol Secure (HTTPS), the secure and encrypted version of Hypertext Transfer Protocol (HTTP) browser communications. HTTPS encrypts Web page data inputs and data through the public Internet and decrypts that Web page and data on the user’s PC or device.
Answer:
True
Explanation:
The Hypertext Transfer Protocol Secure (HTTPS) encrypts the data exchanged between computers.
In this case, between a user's computer and their bank.
The data is encrypted so if anyone is "listening" on the data stream, they'll be able to intercept some the exchange, but it will all be encrypted so they're won't be able to read the information exchanged.
HTTPS has become the standard protocol for all secure transactions, not only with banks but with online stores as well.
The statement is true. HTTPS is required for online banking to secure the communication between a user's device and the bank's servers, ensuring that sensitive data is encrypted during transmission.
Customers who engage in online banking on their laptops or personal computers must use Hypertext Transfer Protocol Secure (HTTPS), which is the encrypted version of Hypertext Transfer Protocol (HTTP). HTTPS ensures that data, such as passwords and other identifiers, transmitted between a user's device and the banking server is encrypted during the transfer. This encryption protects the content of your communications from being intercepted or read by unintended actors.
While HTTP transmits information unencrypted, HTTPS, indicated by the presence of an appended 's' in the web address, uses encryption protocols like the Diffie-Hellman key exchange to secure communications. Therefore, only the user's device and the banking website's servers can decrypt and access the transmitted web page data and inputs.
A blue compressor clutch indicates that it's been slipping due to too
Final answer:
A blue compressor clutch indicates that it's been slipping due to too much friction. To address this issue, one might need to replace the clutch and ensure proper belt tension and lubrication.
Explanation:
A blue compressor clutch indicates that it's been slipping due to too much friction. The compressor clutch is a component in a car's air conditioning system that engages and disengages the compressor to control the cooling process. When the clutch slips, it means it is not properly engaging with the compressor, which can result in reduced cooling performance and potential damage to the clutch itself.
To address a slipping compressor clutch, you might need to replace it with a new one. Additionally, checking the belt tension and lubricating it properly can also help prevent clutch slipping. It's always best to consult a professional mechanic for an accurate diagnosis and appropriate solution to the issue.
You will create two classes, one for a box and one for a triangle. Each of the figures, the box and the triangle, will have an offset telling how far they are indented from the edge of the screen. Each figure will also have a size, although the size will be determined differently for a box and a triangle. For a box, the size is given as the width and the height, expressed in the number of characters. Because characters are taller than they are wide, a box will look taller than you might expect when it is written on the screen. For a triangle, the size will be given by its base. The triangle will point up, and the base will be at the bottom. The slope of a side of the triangle is limited to what you get by indenting one character per line. So once the base is chose, you have no choice regarding what the sides of the triangle will be. We also assume that the base size of a triangle must be odd. The following shows a sample of a 5-by-5 box and a triangle with base of size 15. Assuming that the offset 10. The

One common method of converting symbols into binary digits for computer processing is called ASCII (American Standard Code of Information Interchange). The uppercase letters A through Z are assigned the numbers 65 through 90, so A has binary code 1000001 and Z has code 1011010. Lowercase letters a through z have codes 97 through 122 (that is, 1100001 through 1111010). ASCII codes, as well as other numerical computer output, normally appear without commas. Write the binary code for the letter k.
Binary code, code used in digital computers, based on a binary number system in which there are only two possible states, off and on, usually symbolized by 0 and 1.
