To view a long list of all files in the /home directory in Bash, you can use
ls -la /home.
What is included in this list?This will list the contents of the /home directory in a long format, including hidden files.
The -l flag specifies that the output should be in long format, and the -a flag specifies that the output should include hidden files. These flags can be used together, like this.
ls -l -a /home
What will be the output?This will produce the same output as the previous command.
Other commands that could be used to achieve the same result include:
list -a /home
ls -la /home
ls -la
However, the first command (list -a /home) is not a valid Bash command, so it will not work.
The second and third commands (ls -la /home and ls -la) are valid Bash commands and will produce the desired output.

You have decided to implement Gigabit Ethernet on your network. Each switch port is connected to a single device. Following the installation, you will find one device connected to a switch that is only running at 100 Mbps.
The term for "You've decided to upgrade your network to Gigabit Ethernet. Every switch port is linked to a single device. Following installation, you will discover one device linked to a switch that is only capable of 100 Mbps.", is crosstalk.
Crosstalk is unwanted signals in a communication channel (like in a telephone, radio, or computer) created by energy transference from another circuit (as by leakage or coupling): discourse that is unrelated to the main issue being addressed.
Crosstalk creates mistakes or hinders data transfer by causing interference on an afflicted pair of conductors or the entire connection. Have you ever overheard someone else's phone call, for example? Interference between neighbouring telephone cables causes this.
In fact, there are two forms of crosstalk and two potential sources of crosstalk in any system. Crosstalk is classified into two types: near-end crosstalk and far-end crosstalk, both of which cause undesired interference between signals on distinct interconnects.

3. An engineer has planned to use Class B network 172.19.0.0 and a single subnet mask throughout the network. The answers list the masks considered by the engineer. Choose the mask that, among the answers, supplies the largest number of hosts per subnet, while also supplying enough subnet bits to support 1000 subnets.
Answer:
11 bits
Explanation:
A Class B network, such as the one described in the question, has an address range of 172.16.0.0 to 172.31.255.255. In order to use a single subnet mask throughout the network, the engineer must choose a mask that provides enough subnet bits to support 1000 subnets while also allowing for a large number of hosts per subnet.
The largest number of hosts per subnet is provided by a mask with the fewest number of subnet bits. However, this would not be sufficient to support 1000 subnets. Therefore, the engineer must choose a mask that provides a balance between the number of hosts per subnet and the number of subnet bits.
One possible mask that meets these criteria is 255.255.248.0. This mask provides 21 subnet bits, which is enough to support up to 2^21 = 2097152 subnets. It also provides 11 host bits, which allows for up to 2^11 = 2048 hosts per subnet. This is the largest number of hosts per subnet among the masks considered by the engineer, while also providing enough subnet bits to support 1000 subnets.

What is a program?Source code is the name given to a computer program that can be read by humans. Because computers can only run their native machine instructions, source code requires the assistance of another computer program to run.
As a result, the compiler of the language can convert source code into machine instructions. (An assembler is used to translate machine language programs.) An executable is the name given to the finished file. As an alternative, source code could run through the language's interpreter.
The operating system loads the executable into memory and launches a process if it is asked to be executed. In order to fetch, decode, and then execute each machine instruction, the central processing unit will soon switch to this process.

Divide the following string of binary numbers into 8-bit binary numbers and then convert each 8-
bit binary number into equivalent text by using the ASCII code.
0101010101101110011010010111010001111001
Answer:
Unity
Explanation:
ASCII stands for American Standard Code for Information Interchange.
It contains a total of 256 characters.
It is a subset of UTF-8, which includes printable characters( like uppercase letters, lowercase letters, and digits) and control characters.
The ASCII values for digits [0-9] range from [4-57], and for uppercase letters[A-Z] range from[65-90], and for lowercase letters[a-z] range from[97-122].
Dividing the 8-bit binary numbers into each 8-bit binary number:
01010101, which, when added (using binary conversion), will equal 85, i.e., U (in ASCII table).
01101110, which, when added (using binary conversion), will equal 110, i.e., n ( in ASCII table).
01101001, which, when added (using binary conversion), will equal 105, i.e., i ( in ASCII table).
01110100, which, when added (using binary conversion), will equal 116, i.e., t ( in ASCII table).
01111001, which, when added (using binary conversion), will equal 121 i.e., y ( in ASCII table).
So, the 0101010101101110011010010111010001111001 is equivalent to Unity using ASCII code.

WPA and AES
Explain WAP and AESWPA served as a temporary WEP security upgrade during the development of the 802.11i wireless security standard. WPA was adopted formally one year before WEP was formally discontinued. Pre-shared keys (PSKs), most frequently referred to as WPA Personal, and the Temporal Key Integrity Protocol (TKIP; /tikp/) are used by the majority of current WPA apps. For the production of keys and certificates, WPA Enterprise uses an authentication server.WPA was a substantial improvement over WEP, but because its fundamental components could be installed via firmware updates on WEP-compatible devices, they still depended on vulnerable components.Lower compatibility standards are often no longer justified. Ten years ago, WPA2 certification became accessible. Any device produced after 2006 with a "Wi-Fi" label must support WPA2 encryption as WPA2 certification became mandated in 2006. It's been eight years since then! You should be good with merely selecting WPA2-PSK because your wifi-enabled gadgets are probably less than 8 to 10 years old (AES).To learn more about WAP refer https://brainly.com/question/26601084

In C, write a recursive function int Palindrome(char mystr[], int len) that checks whether the string char mystr[]="....." is a palindrome or not. If it is then print "Palindrome" and if not print "Not palindrome" to the console. A string being a palindrome has 2 cases:(i)if the string has an even length, then the first half is a mirroring of the second half; e.g., abccba is a palindrome, whereas abccab is not. (ii) if the string has an odd length, then disregard of the letter in the middle, the first half is a mirroring of the second half; e.g., abcvcba is a palindrome, whereas abccvba is not.
#include <stdio.h>
#include <string.h>
int Palindrome(char mystr[], int len)
{
// base case: if the length of the string is 0 or 1, it is a palindrome
if (len <= 1)
return 1;
// check if the first and last characters are the same
if (mystr[0] != mystr[len - 1])
return 0;
// if the first and last characters are the same, check the substring that
// lies between them (excluding the first and last characters)
return Palindrome(mystr + 1, len - 2);
}
int main()
{
char mystr[] = "abcba";
int len = strlen(mystr);
if (Palindrome(mystr, len))
printf("Palindrome\n");
else
printf("Not palindrome\n");
return 0;
}
This function works by checking the first and last characters of the string. If they match, it calls itself with a substring that excludes the first and last characters. This process continues until the length of the string is 0 or 1, at which point it returns 1 (indicating that the string is a palindrome). If any of the characters do not match, the function returns 0 immediately.

ADVANTAGES OF JAVASun Microsystems first introduced Java, a general-purpose, high-level programming language, in 1995. It is free to use, cross-platform, and intended to have as minimal implementation requirements as possible. It is class-based, object-oriented, and concurrent. Java is, in a nutshell, a computing platform on which users can create programs.Similar to C++, Java has been reduced to remove language features that frequently result in programming errors. The source code files, or files with a.java extension, are converted into bytecode, or files with a.class extension, in a process called as compilation. An interpreter for Java can then run this. A just-in-time compiler can translate bytecode straight into machine language instructionsIt's simple to learn Java. There is no prerequisite knowledge of fundamental programming languages needed to use the language. Java is not compiled into a platform-specific machine when it is compiled, unlike other programming languages like C++. This implies that a program can be simply performed on any other machine without requiring any changes after being compiled on one.Due to Java's multithreading capabilities, users may create interactive apps that function without a hitch. Systems free of viruses and tampering can be created using its security features. Public-key encryption serves as the foundation for authentication methods.

False. The non-linearity of the logistic regression is obtained NOT because of the use of a non-linear activation function.
What is the reason for non-linearity of the logistic regression?
The most commonly utilised activation functions are non-linear functions. It makes it simple for a neural network model to adapt to diverse types of data and distinguish between distinct outputs.
When the classes can be distinguished in the feature space by linear bounds, logistic regression is typically utilised as a linear classifier. However, if we happen to have a better understanding of the form of the decision border, that can be fixed. As a linear classifier, logistic regression is well recognised and utilised. In order to distinguish between observations that belong to a class and all other observations that do not, it is utilised to create a hyperplane in feature space. As a result, the decision boundary is linear. It is simple to use logistic regression as a linear classifier because there are many reliable and effective implementations available (such as scikit-learn).
