Apple iMac 21.5 inch

Apple introduced the first iMac more than a decade ago. And the design philosophy remains the same: an all-in-one computer thats as powerful as it is beautiful.

Big, beautiful displays. 21.5-inch
The new iMac has come a long way from the first 15-inch iMac. Take one look and youll see just how far. A 21.5-inch or 27-inch display with edge-to-edge glass covers nearly the entire front of the enclosure. When all you see is the display, nothing gets between you and whats onscreen. Movies, TV shows, websites, photos? everything looks stunning on the new 16:9 widescreen iMac display.

LED backlighting.
When a display has more pixels, you need to push more light through them to achieve the best picture possible. LED backlighting in the new iMac does exactly that, with remarkable brightness and efficiency. Because the LED backlight doesnt take up much space, the iMac enclosure stays thin? even with all the high-performance components inside

Higher resolution.
The new 21.5-inch iMac features 1920-by-1080 HD resolution. Apple engineers could simply have stretched that resolution up and out for the 27-inch iMac. Instead, they took the display well beyond HD with 2560-by-1440 resolution. Thats 78 percent more pixels than the 21.5-inch iMac.

IPS technology.
The iMac display is designed to look great from almost any angle. A technology called in-plane switching (IPS) makes this possible. Whether youre sitting in front of the display or standing off to the side, youll get a perfect picture with superb color consistency and no loss of detail.

Clutter-free wireless.
iMac embodies simple design that eliminates desktop clutter. So naturally, its the first Mac to come standard with the Apple Wireless Keyboard and the new wireless Magic Mouse.

Multi-Touch technology.
Magic Mouse is designed to do all the things a mouse should do pointing, clicking, and scrolling but with no scroll wheel, no trackball, and no visible button. Magic Mouse uses Multi-Touch technology to let you click, scroll, or swipe anywhere on its perfectly smooth, seamless top shell. But the real magic of Magic Mouse is how it knows what you want to do. A chip inside Magic Mouse acts as a brain, detecting the difference between a resting hand, a scrolling finger, a two-finger swipe, and a simple click. Its the smartest mouse weve ever made

Evolution of iMac.
It was a great idea then, and its a great idea now. The all-in-one design of the first flat-panel iMac cleaned up the desktop. It put everything you need? display, processor, graphics card, hard drive, optical drive, memory, and more? inside one simple enclosure. New technology inside and out makes the new iMac a worthy addition to the all-in-one dynasty.

Seamless enclosure.
While youll find a collection of ports on the back of iMac, you wont find much else. A seamless, precision-forged enclosure makes the back one continuous aluminum surface. And there?s only one cord: the power cord.

Cool, quiet components.
The wider iMac display allows more room to separate the two hottest components, the CPU and the GPU. This keeps things cool inside the iMac enclosure. Apple engineers also implemented an intelligent control system that monitors temperatures and delivers just the right amount of airflow to critical components. And the three fans inside iMac have been tuned to be ultraquiet. The result of all this tinkering with heat and sound A system that operates at 18 decibels when idle so quiet, you hardly know its on.
