A group of computers that share resources on or provided by network nodes is referred to as a computer network.
What is computer network ? In order to communicate with one another, the computers use standard communication protocols through digital networks. These linkages are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency means that may be organized in a number of computer network. Among the nodes of a computer network are laptops, servers, networking equipment, and other specialized or general-purpose hosts. In addition to having hostnames, they are recognized by network addresses. Hostnames act as distinctive designations for the nodes and are hardly ever modified after first assignment. For communication protocols like the Internet Protocol to locate and identify the nodes, network addresses are used.Computer networks can be categorized using a variety of factors, such as the signal-transmission medium, bandwidth, communications protocols used to manage network traffic, network size, topology, traffic-control mechanism, and organizational goals.Internet connectivity, digital video and audio, the shared use of application and storage servers, printers, fax machines, and email and instant messaging software are just a few of the many applications and services supported by computer networks.To Learn more About computer network refer to:

1. Payroll Program with Input Validation Design a payroll program that prompts the user to enter an employee's hourly pay rate and the number of hours worked. Validate the user's input so that only pay rates in the range of $7.50 through $18.25 and hours in the range of 0 through 40 are accepted. The program should display the employee's gross pay.
The payroll program that prompts the user to enter an employee's hourly pay rate and the number of hours worked is made with the help of Do While loop.
What is Program?A sequence or set of instructions written in a programming language for a computer to follow is called a computer program. Software includes documentation and other intangible components in addition to computer programs. Source code is the human-readable version of a computer program. Because computers can only execute their own native machine instructions, source code must be executed by another computer program.
Given to make a payroll program,
Program is made with Do While loop,
A condition and a process symbol make up the do while construct. First, the block's code is executed. After that, the situation is looked at. The block's code is executed once more if the condition is met. This continues until the condition is true.
The program code is,
Do While payRate > 7.5 AND payRate < 18.25
Display "Enter hourly pay rate: "
Input payRate
End While
Do While hoursWorked > 0 AND hoursWorked < 40
Display "Enter number of hours worked: "
Input hoursWorked
End While
grossPay = payRate * hoursWorked
Display "The employee gross pay is " + grossPay

What is the correct syntax for an input() function that asks the user to input a random number and store it in a variable called random_number?
The Python randint () method is used to produce random numbers. In the random module, this function is defined.
Explain about the random numbers?By watching some unpredictable external input, such as mouse movements or fan noise, then synthezising data from it, computers may produce really random numbers. Entropy is the scientific term for this. Other times, they create "pseudorandom" numbers using an algorithm to make the results seem random even when they aren't.
Random number generation is the technique of generating a series of numbers or symbols that cannot be fairly predicted with a higher degree of certainty than by chance alone.
Creating data encryption keys, simulating and modelling complicated processes, and picking random samples from bigger data sets are just a few of the many uses for random numbers.

how do you make a short secret, such as a password, become long enough for use? salting key elongation ephemeral operations key stretching
We can extend the length of a short secret, like a password, by employing a method called (D) key stretching.
What is key stretching?In order to make it more difficult for a brute-force assault, the idea behind key stretching is to add a random string of characters to the password hash: BCRYPT:
Key stretching techniques are used in cryptography to increase the resources (time and sometimes space) required to test each potential key, hence boosting the security of a key that may be weak, usually a password or passphrase, against a brute-force assault.
Human-generated passwords or passphrases are frequently brief or predictable enough to be cracked, but key stretching aims to thwart such assaults by making the straightforward process of trying one password candidate more challenging.
In some real-world applications where the key length has been limited, key stretching enhances security by simulating a greater key length from the viewpoint of a brute-force attacker.
Therefore, we can extend the length of a short secret, like a password, by employing a method called (D) key stretching.

What context switch time, associated with swapping?When the CPU is transferred from one process to another that is in an advanced stage of readiness to run, the kernel swaps contexts, which results in a context switch. When a whole process is transferred to the disk, swapping occurs. To find out if a process is in pause mode, perform a context switch.
The context switch time equals T – (SUM of all processes (waiting time + execution time)) if the sum of all processes' execution times equated T.

A. Client/server networks are cheaper to install.
B. Security is weaker on client/server networks
C. They do not require dedicated servers like P2P networks.
D. They are more scalable than P2P networks.
The central administration of applications and data is a significant benefit of the client-server network. A client-server network speeds up data transfer while also securing the data sent.
Using the network is a wise choice for organizations seeking faster and more secure data transport. Because the files are centralized, it is easier to perform consistent file backups. File duplication is no longer a concern, and the security issues associated with peer-to-peer networks are eliminated because everyone on the network just needs access to the central server. When establishing a P2P network, there is no need to purchase a separate computer to function as a server.
