iMac (20-inch, 2.26GHz Core 2 Duo, Mid/Edu 2009)
The iMac (20-inch, 2.26GHz Intel Core 2 Duo, Mid/Edu 2009) introduced in Mid 2009 for educational purposes only has half the RAM capacity, a smaller hard drive and an integrated Nvidia graphics. This is the all-in-one desktop computer in a glass and aluminum one-piece casing behind the 20” screen, mounted on an aluminum stand with a slightly tapered foot and an adjusting hinge. Yet the hardware had been revised. The memory clockspeed was increased up to 1066 MHz, the memory type was also upgraded up to DDR3. The entry-level iMacs of 2009 sports Nvidia Geforce Graphics, while top models – ATI Radeon. The FireWire “400” port was dropped for an extra USB port thus making four of them in total and the Mini-DVI was swapped for Mini DisplayPort. The processor remained the same. The iMac (20-inch, 2.26GHz Intel Core 2 Duo, Mid/Edu 2009) features a 2.26 GHz Intel “Core 2 Duo” processor (P7550), with two independent processor “cores” on a single silicon chip, 1 GB of RAM (2 GB since May 3, 2011), a 160 GB Serial ATA hard drive (7200 RPM), a slot-loading DVD+R DL “Super Drive”, NVIDIA GeForce 9400M graphics with 128 MB of memory shared with the system, a built-in iSight webcam and stereo speakers, as well as a Firewire “800” and 4 USB 2.0 ports. It also has built-in draft and enabled AirPort Extreme (802.11g) and Bluetooth 2.1+EDR, Gigabit Ethernet and Mini DisplayPort capable of supporting a second display. The cooling system is CPU controlled and the in-built speakers are mounted beneath the 20-inch screen for the sound to bounce off the desk or other surface. The speakers’ grills also work as the vent ones. The iMac (20-inch, 2.26GHz Intel Core 2 Duo, Mid/Edu 2009) is shipped with a smaller Apple Keyboard short of the numerical keypad and Mighty Mouse.
