Here we'll describe the external ports and connectors on the iMac (Early 2006) computer. You can find them on the bottom right side of the back of the computer, known as the Input/Output (I/O) panel.
Ports and connectors
- Mini-DVI video output port
- Ethernet Port (10/100/1000 Gigabit Base-T)
- Audio line-in port
- Headphone out / optical audio out port
- USB 2.0 ports (three ports)
- FireWire ports (two ports)
Mini-DVI video output port
Using the Mini-DVI video out port, you can use a compatible DVI display, VGA display or projector in extended desktop or video mirroring mode with the appropriate Apple Mini-DVI adapter.
- For DVI displays, use the Apple Mini-DVI to DVI Adapter (M9321G/A).
- For VGA displays or projectors use the Apple Mini-DVI to VGA Display Adapter (M9320G/A).
- For televisions, projectors or VCRs that use S-video or composite video connectors, use the Apple Mini-DVI to Video Adapter (M9319G/A).
Video mirroring allows you to see the same image that is on the iMac (Early 2006) computer's flat-panel display on an external monitor, television or projector.
Extended desktop mode allows you to connect an external display and use that area in addition to the built-in display for your desktop.

Ethernet Port (10/100/1000 Gigabit Base-T)
The iMac (Early 2006) has a built-in 10/100/1000 Gigabit Ethernet port. The iMac (Early 2006) computer can be connected to an Ethernet cable from a cable or DSL modem, hub, switch, or router, or to another Macintosh computer. The connected device can be either a 10Base-T, 100Base-T or a 1000Base-T device; the port automatically detects which type of device is connected. You don't have to use an Ethernet crossover cable to connect to other Ethernet devices.
Audio Line-in Port
Analog audio line input minijack; up to 16-bit stereo and 44.1 kHz sampling rate.
The external sound input jack is a 3.5 mm mini phone jack. The sound input jack accepts line-level stereo signals. It also accepts a stereo miniplug-to-RCA cable adapter for connecting stereo equipment to the computer.
The iMac (Early 2006) also has a built-in microphone near the built-in iSight camera at the top of the computer screen bezel.
Headphone out / optical audio out port
The headphone / line output jack accommodates both digital optical audio output and analog audio output with a 24-bit, 16-96 kHz D/A converter. For analog headphone / line output a standard audio cable with 3.5mm metal plug should be used. For digital audio, a fiber optic cable with 3.5mm plastic or nylon optical plug should be used.
Three USB (Universal Serial Bus) 2.0 Ports
The back of the iMac (Early 2006) has a total of three USB 2.0 compliant ports. You can connect both USB 2.0- and USB 1.1-compliant devices to these ports. The keyboard also contains a USB hub with two USB 1.1-compliant ports.
All the USB ports use USB Type A connectors, which have four pins each.
The USB 2.0 ports support both low-speed, full-speed and high-speed data transfers, at up to 1.5 megabits per second (Mbit/s), 12 Mbit/s, and 480 Mbit/s respectively.
Two FireWire 400 Ports
The iMac (Early 2006) features two 400 Mbit/s FireWire (IEEE 1394) ports. 400 Mbit/s is a theoretical maximum load, and actual rates will vary. This port is used by iPods, as well as third-party devices such as video cameras or external drives.
The iMac (Early 2006) computer supports Target Disk Mode (TDM).
