A desktop environment is a collection of software designed to give functionality and a certain look and feel to an operating system.. This article applies to operating systems which are capable of running the X Window System, mostly Unix and Unix-like operating systems such as Linux, Minix, illumos, Solaris, AIX, FreeBSD and Mac OS X.

MSI Raider 18 HX Gaming Laptop. Now this is a powerhouse gaming laptop. This beast of a computer got the same Intel processor and NVIDIA graphics card as the desktop above.
Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. [10] Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv).

For instance, argon, krypton, and xenon form clathrates with hydroquinone, but helium and neon do not because they are too small or insufficiently polarizable to be retained. [61] Neon, argon, krypton, and xenon also form clathrate hydrates, where the noble gas is trapped in ice. [62] An endohedral fullerene compound containing a noble gas atom
A krypton laser is an ion laser using ions of the noble gas krypton as its gain medium.The laser pumping is done by an electrical discharge.Krypton lasers are widely used in scientific research, and in commercial uses, when the krypton is mixed with argon, it creates a "white-light" lasers, useful for laser light shows.
Krypton is used in some photographic flashes for high speed photography. Krypton gas is also combined with mercury to make luminous signs that glow with a bright greenish-blue light. [39] Krypton is mixed with argon in energy efficient fluorescent lamps, reducing the power consumption, but also reducing the light output and raising the cost. [40]
By the early 1980s, the chaos and incompatibility that was rife in the early microcomputer market had given way to a smaller number of de facto industry standards, including the S-100 bus expansion board, the CP/M operating system, the Apple II home computer, the use of the programming language Microsoft BASIC in read-only memory (ROM), and the 5 + 1 ⁄ 4 inch floppy drive storage medium.
