Investigation 1: Host Installation
Install CentOS directly on your drive following the guidelines below:
Networking should be on.
Set the hostname of the machine to be host..ops. Check blackboard for your assigned domain name.
Set the timezone to Americas/Toronto
Select Server with GUI as the installation type.
The partition setup will be similar to what you had in previous OPS courses.Delete any old partitions on the drive.
Provide a separate mount point for ‘/var/lib/libvirt/images with at least 100GB.
Set a good root password. No, not ‘P@ssw0rd’.
Create a non-privileged user account using your MySeneca ID.If your MySeneca ID is long enough that typing it would be irritating to do on a regular basis you may use an alternate name, but you must clear it with me first.
On First Boot
Make sure your machine meets the following conditions:
Your NIC is set to automatically turn on when the machine does.
SELinux is set to enforcing.
The machine must be fully updated.
Use firewalld as your firewall.
Install libvirt and virt-manager. Set the virtualization service to start automatically when the machine boots.
Reboot your machine
Investigation 2: Basic Service Installation
Configure the postfix service on your host to send and receive email for your domain.
Install bind and configure your host as the master DNS server for your domain.It must provide forward and reverse lookups of the machines in your domain.
As the course goes on, you will add entries to your zone for the machines you create.
Create an MX record to direct all mail sent to users @.ops to your host.
It must allow machines in your virtual network to access the outside world (e.g. to get updates).
Ensure both services (postfix and named) start automatically when the machine boots, and allow the traffic for both through your firewall.
Investigation 3: Virtual Network & Machine Installation
Remove the default virtual network.
Create a new virtual network called opsnet.Address: 192.168.[x].0/24, where x is the network number on blackboard. E.g. if your network number is 29, your opsnet network will be 192.168.29.0/24.
Disable DHCP, and allow forwarding to any physical device using NAT.
Install a new vm using the same CentOS release as the host machine.You may wish to provide the VM access to more than 1 CPU and 1 GiB of RAM so it installs and updates faster.
During the installation process:Set the hostname to blank..ops, using the same domain name as the host machine.
Provide your machine with a static address of your choice, using the host’s address for the primary DNS server and the gateway.
Set the timezone to Americas/Toronto.
Use a minimal installation (no GUI).
Set your root password, and create a non-privileged user account using your MySeneca ID.
If your MySeneca ID is long enough that typing it would be irritating to do on a regular basis you may use an alternate name, but you must clear it with me first.
Once the machine is installed, ensure it is fully updated.
Shut down your VM, make sure the resource settings are reduced back to 1 CPU and 1 GiB of RAM.
When you need a new VM, clone this one.

A majority gate is a logical gate used in circuit complexity and other applications of
Boolean circuits. The output of the majority function is 1 if the majority of its inputs (i.e., two or
three of the three inputs) are 1 and 0 otherwise. In other words, a majority gate returns true if and
only if more than 50% of its inputs are true.
(a) Using Digital/Logisim, draw the full circuit of a three (3) input majority “gate” using basic
logic gates. (Hint: Begin by drawing the truth table that satisfies the conditions a majority
gate).
(b) Derive the equation representative of the circuit.

Hi, I have attached below the instructions for this assignment so please take a look at that to see what needs to be done for this assignment. The instructions are in html format so I had to make a zip file to upload them here. Please make sure to follow the instructions/guidelines provided to complete the assignment! This is very important! I have also attached the zip file of the target. It is supposed to be a tar file, but it didn’t let me submit as a tar file on Studypool so I had to convert it to zip file, but please convert it back to a tar file as that may be more useful in completing this assignment. This is for a Introduction to Computer Organization course. The language we are using is C and we are using the linux server. Let me know if you have any questions or if there’s something that you find confusing about the instructions that you would like me to clear up with you!

Linux is a free and open-source operating system kernel that serves as the foundation for various Linux distributions, commonly referred to as “Linux distros.” Developed by Linus Torvalds and released in 1991, Linux has since become one of the most popular operating systems for a wide range of devices, including servers, desktop computers, smartphones, embedded systems, and more.
One of the key features of Linux is its open-source nature, which means that the source code is freely available for anyone to view, modify, and distribute. This has led to a large and active community of developers and enthusiasts who contribute to the development and improvement of the operating system.
Linux distributions combine the Linux kernel with additional software, including system utilities, libraries, desktop environments, and applications, to create complete operating systems. Some well-known Linux distributions include Ubuntu, Debian, Fedora, CentOS, Arch Linux, and Linux Mint, among others. Each distribution may have its own specific focus, target audience, and package management system, but they all share the common Linux kernel.
Linux offers numerous benefits, including stability, security, flexibility, and a vast array of software options. It is highly customizable and can be tailored to meet specific needs. Linux is known for its robust command-line interface, which provides powerful control and flexibility over the operating system. Additionally, Linux supports a wide range of software and hardware, making it a popular choice for both personal and enterprise use.
Linux has been widely adopted in server environments due to its reliability, scalability, and the availability of server-oriented distributions. It also powers many internet services, including web servers, databases, and cloud computing platforms. Linux-based distributions have gained popularity in the desktop market as well, offering user-friendly interfaces and a wide range of applications.
Overall, Linux has had a significant impact on the technology industry, promoting open-source software and providing an alternative to proprietary operating systems. Its flexibility, security, and community-driven development model continue to make it a popular choice for a variety of applications.
