Elaborate the difference between Unix and Windows . 

Unix arose from a failed attempt by several employees of AT&T Bell Labs in the early 1960s to develop a reliable time-sharing operating system. Despite the failed attempt, Ken Thompson and Dennis Ritchie of Bell Labs didn't give up. They created an integrated development environment described as being "of unusual simplicity, power, and elegance." The operating system took off, and today it runs many of the world's web sites and cloud computing platforms.

In the 1980s, an up-and-coming competitor to Unix called Windows began gaining popularity, in part because of the increasing power of microcomputers with Intel processors. At the time, Windows was the only major operating system designed for this type of proce7ssor, and Unix was used manly on servers. Today, there are distributions of Unix and Unix-like operating systems such as Linux that run on a PC.

There are two types of operating systems:

• CLI-based operating system: You type a text command in a terminal, and the computer carries out that command. The computer's response is in plain-text format.
• GUI-based operating system: You interact with the computer by selecting objects such as buttons, icons, and menus on the desktop or in applications using a mouse, keyboard, or touch screen.

Windows is designed for use with a GUI. It has a Command Prompt window, but only those with more advanced Windows knowledge should use it. Unix natively runs from a CLI, but you can install a desktop or windows manager such as GNOME to make it more user-friendly.

Unix is flexible, and you can install it on all types of computers, including mainframes, supercomputers, and microcomputers. Unix also inspires novel approaches to software design, such as solving problems by interconnecting simpler tools instead of creating large, monolithic applications.

The Windows operating system is more limited than Unix in terms of what it can do, but it's relatively easy for anyone to use.

Unix is more stable and doesn't crash as often as Windows, so it requires less administration and maintenance. Unix has greater security and permissions features than Windows out of the box and is more efficient than Windows. Unix also has a massive online community that you can draw on for troubleshooting or learning new command-line skills. Operating system upgrades from Microsoft often require you to purchase new hardware; this isn't the case with Unix.

Microsoft maintains a massive knowledge base for its operating system. That knowledge base, coupled with a vibrant user community, can help resolve technical issues relatively easily. Windows supports a large library of software, utilities, and games, as well as extensive plug-and-play support. You can configure Windows to install updates automatically to improve security, as well as add or improve features. With Unix, you must install such updates manually.
