  Types of network adapters in VirtualBox In VirtualBox there’s multiple types of network adapters that can be used to configure virtual machines for different networking needs. Down below will give you a brief overview of each type. NAT (network address translation) The VM is placed behind a VirtualBox-managed router. This allows the VM to access the external network via the networks host’s IP, but the VM itself remains invisible to the outside. Its most suitable for simple internet access with minimal configuration NAT network This is like NAT, but it allows multiple VM’s to communicate with each other in the same NAT network all while sharing the host’s internet connection. Its commonly used when you want to simulate a small, isolated network of VM’s that can also access the internet. Bridged adapter This VM is connected directly to the physical network as if it is a separate device, it also receives its own IP address from the same network as the host. This is ide...

  CAT cables Theres many types of CAT cables, and they are commonly used for Ethernet and other networking purposes.   Types Theres 5 main types of CAT cables: ·           CAT5e (Category 5e): This is an enhanced version of the CAT5 cable, offering improved performance and support for higher data transfer rates. It is suitable for most home and small business networking needs. ·           CAT6 (Category 6): CAT6 cables provide even higher data transfer rates and reduced crosstalk compared to CAT5e. They are commonly used in professional installations and are suitable for gigabit Ethernet and some 10-gigabit applications. ·           CAT6a (Category 6a): The "a" stands for "augmented." CAT6a cables are an enhanced version of CAT6, offering even higher data transfer rates and better performance, especially in terms of crosstalk and signal quality...

  VLAN This is our set up, the two computers on the side are part of the Preminger VLAN. theses computers can interact with each other but not with the other 2 computers on the Jafar VLAN. Below is the step by step process of how these two VLAN's were created. I manually added the VLAN's to the data base as seen below.  Network table Device name IP address Subnet mask Default gateway PC 0 198.162.10.1 255.255.255.0 N/A PC 1 198.162.10.2 255.255.255.0 N/A PC 2 198.162.10.3 255.255.255.0 N/A PC 3 198.162.10.4 255.255.255.0 N/A

  Algorithms Objective: Write a python script to automate the daily sending of email messages. The script should generate a daily message and send it via email. import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText import schedule import time # Function to send email def send_email ( subject , body , to_email ):     # email credentials     sender_email = "#for security reasons this will be hidden"     sender_password = " #for security reasons this will be hidden "       # Create message     message = MIMEMultipart()     message[ "From" ] = sender_email     message[ "To" ] = to_email     message[ "Subject" ] = subject     message.attach(MIMEText(body, "plain" ))     # Connect to the SMTP server (Gmail in this case)     with smtplib.SMTP( "smtp.gmail.com" , 587 ) as server:         server....

  Data breach What's the impact of a data breach on clients and customers?   Online retailers gather a vast array of data about their customers to enhance user experience, personalize marketing, and optimize operations. This data typically includes personal information like names, addresses, and payment details, as well as transaction history, browsing behaviour, and preferences.
