what are the commands to lock a computer

Using the knowledge in computational language in python it is possible to write a code that the pseudocode outline of your program;

import sys

import os

def main():

   # Check and retrieve command-line arguments

   if len(sys.argv) != 3:

       print(__doc__)

       sys.exit(1)   # Return a non-zero value to indicate abnormal termination

   fileIn  = sys.argv[1]

   fileOut = sys.argv[2]

   # Verify source file

   if not os.path.isfile(fileIn):

       print("error: {} does not exist".format(fileIn))

       sys.exit(1)

   # Verify destination file

   if os.path.isfile(fileOut):

       print("{} exists. Override (y/n)?".format(fileOut))

       reply = input().strip().lower()

       if reply[0] != 'y':

          sys.exit(1)

   # Process the file line-by-line

   with open(fileIn, 'r') as fpIn, open(fileOut, 'w') as fpOut:

       lineNumber = 0

       for line in fpIn:

           lineNumber += 1

           line = line.rstrip()   # Strip trailing spaces and newline

           fpOut.write("{}: {}\n".format(lineNumber, line))

           # Need \n, which will be translated to platform-dependent newline

       print("Number of lines: {}\n".format(lineNumber))

if __name__ == '__main__':

Create and maintain databases that are appropriate for the needs of their organizations, as database managers or administrators. These IT specialists are in charge of maintaining, storing, protecting, and troubleshooting databases.

What is database management?

Data is stored, retrieved, and analyzed using software called database management systems (DBMS). Users can create, read, update, and delete data in databases using a DBMS, which acts as an interface between them and the databases.

A software program is used to administer databases, or database management systems. As an illustration, popular commercial databases like MySQL, Oracle, etc. are utilised in a variety of applications.

A DBMS provides an interface for carrying out a variety of tasks, including building databases, putting data in them, updating data, creating tables in the databases, and many other things.

It offers database security and safety. Additionally, it preserves data consistency when there are many users.

Hence to conclude dbms has the responsibilty of overseeing the data and operation of databases

Answer:

D!

Explanation:

The term that describes how relatively small units of data called packets are routed through a network based on the destination address contained within each packet is called "Packet Switching"

Packet switching is used to maximize the use of available channel capacity in digital telecommunication networks, such as computer networks, as well as to reduce transmission latency (the time it takes for data to travel across the network) and boost communication resilience.

Packet switching is most frequent on data networks such as LANs, WANs, and the Internet. It is particularly suited to data transmission because it lets networks to swiftly adapt to changing conditions. If one of the network's routers dies, for example, packets can be automatically re-routed to avoid that device.

Since you want to identify all devices on a network along with a list of open ports on those devices. you want the results displayed in a graphical diagram. the tool that you use is Port scanner.

Finding open ports on a network that might be receiving or transferring data is a process called port scanning. In order to find vulnerabilities, it also entails sending packets to particular ports on a host and examining the answers.

Note that Only when used with a residential home network or when specifically approved by the destination host and/or network are network probing or port scanning tools allowed. Any kind of unauthorized port scanning is absolutely forbidden.

It is to be noted that at a basic level, the needs and preferences that must first be understood to determine a product’s functionality or practical use is that of the consumer.

A consumer is a person or group who wants to order or utilizes acquired items, products, or services primarily for personal, social, family, or home purposes and is not actively involved in entrepreneurial or company operations.

The term "functionality" relates to whether a design works and assists people in meeting their goals and requirements. Functionality varies but is present in everything from chairs and tables to books and online interfaces. When a design is extremely functional, it accomplishes its job and does it well.
