Explanation / Answer

Linux: Linux (i/'l?n?ks/ lin-?ks[5][6] or /'l?n?ks/ lin-uuks)[7][8][9] is a Unix-like computer operating system assembled under the model of free and open source software development and distribution. The defining component of any Linux system is the Linux kernel, an operating system kernel first released October 5, 1991 by Linus Torvalds.[10][11] Linux system distributions may vary in many details of system operation, configuration, and software package selections. Linux runs on a wide variety of computer hardware, including mobile phones, tablet computers, network routers, televisions[12][13], video game consoles, desktop computers, mainframes and supercomputers.[14][15][16][17] Linux is a leading server operating system, and runs the 10 fastest supercomputers in the world.[18] In addition, more than 90% of today's supercomputers run some variant of Linux.[19] The development of Linux is one of the most prominent examples of free and open source software collaboration: the underlying source code may be used, modified, and distributed—commercially or non-commercially—by anyone under licenses such as the GNU General Public License. Typically Linux is packaged in a format known as a Linux distribution for desktop and server use. Some popular mainstream Linux distributions include Debian (and its derivatives such as Ubuntu), Fedora and openSUSE. Linux distributions include the Linux kernel, supporting utilities and libraries and usually a large amount of application software to fulfill the distribution's intended use. A distribution oriented toward desktop use may include the X Window System and an accompanying desktop environment such as GNOME or KDE Plasma. Other distributions may include a less resource intensive desktop such as LXDE or Xfce for use on older or less powerful computers. A distribution intended to run as a server may omit all graphical environments from the standard install and instead include other software such as the Apache HTTP Server and an SSH server such as OpenSSH. Because Linux is freely redistributable, anyone can create a distribution for any intended use. Applications commonly used with desktop Linux systems include the Mozilla Firefox web browser, the OpenOffice.org and LibreOffice office application suites, and the GIMP image editor. Because the main supporting user space system tools and libraries orginated in the GNU Project, initiated in 1983 by Richard Stallman, the Free Software Foundation prefers the name GNU/Linux.[20][21] Mobile digital Devices & Cloud-connected computers: A personal digital assistant (PDA), also known as a palmtop computer, or personal data assistant,[1][2][3] is a mobile device that functions as a personal information manager. Current PDAs often have the ability to connect to the Internet. A PDA has an electronic visual display, enabling it to include a web browser, but some newer models also have audio capabilities, enabling them to be used as mobile phones or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless Wide Area Networks. Many PDAs employ touchscreen technology. The first PDA was released in 1986 by Psion, the Organizer II. Followed by Psion's Series 3, in 1991, which began to resemble the more familiar PDA style. It also had a full keyboard. [4][5] The term PDA was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton. In 1996, Nokia introduced the first mobile phone with full PDA functionality, the 9000 Communicator, which grew to become the world's best-selling PDA. The Communicator spawned a new category of mobile phones: the "PDA phone", now called "smartphone". Another early entrant in this market was Palm, with a line of PDA products which began with the March 1996 Pilot 1000. Today, almost all PDAs are smartphones. Over 150 million smartphones are sold each year, while "stand-alone" PDAs without phone functionality sell only about 3 million units per year
