What is FreeBSD?

FreeBSD is a free Unix-like operating system. It comes from Research Unix via the Berkeley Software Distribution (BSD), It is also known as “Berkeley Unix. ”FreeBSD is used everywhere. In fact, there’s a chance you’re using at least some code from FreeBSD in your everyday life. If you stream movies via Netflix, or play PlayStation 4 game sensation. Also some companies and applications use FreeBSD like Apple, Cisco, Dell/Compellent, EMC/Isilon, Intel/McAfee, Juniper, Microsoft Azure, NetApp, Netgate, NYI, Quest KACE, Sony, Stormshield, Verisign, VMware Yahoo!, and more.

What Are Open Sources from FreeBSD?

FreeBSD is an open-source operating system that uses various open-source software and technologies. Some of the open-source components used in FreeBSD include:

1. Kernel - The core of the operating system, written in C and ASM.
2. Binutils - A set of tools for creating, linking, and manipulating binary files.
3. GCC - The Gnu Compiler Collection, a popular open-source compiler used to build software on FreeBSD.
4. Clang - An open-source C, C++, and Objective-C compiler that is widely used on FreeBSD.
5. BSDLibc - The BSD implementation of the C standard library, used in FreeBSD and other BSD-based operating systems.
6. X Window System - A graphical windowing system used to run graphical user interfaces on FreeBSD.
7. Gnome - A popular desktop environment used on FreeBSD.
8. KDE - A desktop environment used on FreeBSD.
9. Apache - A widely-used web server that is included in the FreeBSD distribution.
10. PHP - A popular server-side scripting language used for building dynamic web pages.

FreeBSD Features

FreeBSD provides users with special features:

• Modules [kernel] loadable dynamically. It allows new System Files, Network Protocols, and Binary Emulators to load into system without creating a new kernel.
• The FreeBSD base system (with FreeBSD 10) includes a new BSD-licensed, legacy-free hypervisor, which can run all supported versions of FreeBSD, as well as OpenBSD and Linux through the grub-bhyve port.
• Multi-users can access, That means a different user can perform their task simultaneously and use all peripherals as shared.
• FreeBSD can communicate with other systems according to the Full TCP / IP connection. It can act as a Primary server and also performs critical duties such as FTP ,Firewall, email services, and Network File System.
• The Ports Collection is a collection of over 23,000 third-party programs that can be installed and operated on FreeBSD with ease.
• If you require access to a large number of third-party programs, FreeBSD has more than four times the number of apps in the ports and packages system as OpenBSD.FreeBSD also offers a wealth of tuneable options for the kernel, filesystem, and network that OpenBSD does not.
• Light-weight jails alternative to virtualization.
• FreeBSD Firewalls: IPFW and IPFilter are included in the basic system, it has also a modified version of the popular pf with better SMP performance. IPFW also contains the dummynet function, which allows network managers to mimic undesirable network circumstances such as latency, jitter, packet loss, and bandwidth limitations.
• It has memory protection which allows applications (or users) to avoid interfering with each other's tasks.
• The industry standard X Window (X11R6) system provides a graphical user interface (GUI) for the most common VGA cards and monitors, including all source code.
• DTrace, a sophisticated event-based performance analysis and troubleshooting tool is heavily ported to FreeBSD.
• Up-to-date online documentation is available.
• FreeBSD is supported by Ultra-DMA peripherals in ISA Bus.

How To Install FreeBSD?

As a language model AI, I don't have personal experiences but I can provide you with the steps to install FreeBSD:

1. Download the ISO image of the latest version of FreeBSD from the official website.

2. Burn the ISO image to a DVD or create a bootable USB drive.

3. Insert the DVD or USB drive into your computer and restart it.

4. Boot from the installation media and select the appropriate language and keyboard layout.

5. Select the option to install FreeBSD and follow the on-screen instructions.

6. Select the disk partitioning method and configure your network settings.

7. Choose the packages you want to install and configure the root password.

8. Wait for the installation process to complete, then restart the computer.

9. Log in to your newly installed FreeBSD system using the root password.

10. Update the system and configure it according to your needs.

What are FreeBSD​ benefits?

FreeBSD is an open-source Unix-like operating system that provides users with a multitude of benefits:

• Easy to Install​ and use: The operating system is designed with a user-friendly interface that makes it easy to navigate and perform common tasks. This makes it an ideal choice for individuals and organizations that need to manage complex systems without spending a lot of time on training or support.

• Free​: FreeBSD is an open-source operating system, which means that it is free to use and available to anyone. This makes it an ideal choice for organizations that are looking for a cost-effective solution for their computing needs. With a large community of developers and users, there is always someone available to help with any questions or issues that may arise.

• Performance: The operating system is optimized for speed, which allows it to handle demanding workloads with ease. This makes it an ideal choice for high-performance computing and large-scale data centers.

• Secure: Security is highly important to FreeBSD, and its developers are continuously trying to make the operating system as safe as possible.BSD and Unix have a well-deserved industry reputation for rock-solid (though not flawless, as misconfiguration can lead to vulnerabilities) security and stability. When we look at the perspective of a number of vulnerabilities that Linux and FreeBSD systems faced.FreeBSD is 7 times lower than Linux in the last 20 years (Of course, Linux is more widely used and is the target of bad actors. Another factor that makes BSD safe is that it is built on a monolithic kernel.

• Stable​: In addition to its Security advantage over other OS, FreeBSD provides a stability edge.FreeBSD servers have been known to run for years without issue. These are sufficient reasons for us to prefer FreeBSD over other OS.

Disadvantages of FreeBSD

FreeBSD is a popular open-source operating system that is based on the Unix-like operating system. Although it has many advantages, there are also some disadvantages that users should be aware of.

1. Limited hardware support: FreeBSD does not have as extensive hardware support as other operating systems like Windows or Linux. This means that users may encounter compatibility issues when attempting to install FreeBSD on certain hardware.

2. Lack of commercial support: As an open-source project, FreeBSD does not have the backing of a commercial entity. This means that users who encounter problems or need assistance may struggle to find reliable support.

3. Smaller software repository: Compared to other operating systems, the repository of software available for FreeBSD is relatively small. This can make it difficult for users to find the specific applications or tools they need.

4. Steep learning curve: For new users, the command line interface and advanced configuration options in FreeBSD can be overwhelming and difficult to navigate. This can make the learning curve steeper than other operating systems.

5. Performance issues: In some cases, FreeBSD may experience performance issues on older or low-end hardware. This is because it has a heavier memory footprint compared to other operating systems, which can cause performance issues.

In conclusion, while FreeBSD has many advantages, its disadvantages should also be taken into consideration when deciding if it is the right operating system for a particular use.
