On the sides of the system you'll find a gigabit Ethernet port, an HDMI port, a SD card reader, two USB 2.0 ports, one USB 3.0 port, and a VGA port. Wireless network connections are handled by the systems 802.11b/g/n Wi-Fi, but there's no Bluetooth for other wireless devices like keyboards and mice. The DVD burner is a throwback, one that might be necessary in your family for watching old DVDs or if you need to access archived pictures on optical discs. The Toshiba Satellite C55D-B5244 is a competent desktop replacement laptop for a nice price, but drawbacks, like a non removable battery and a somewhat flimsy keyboard, keep it in the middle of the pack. Even features like 6GB of system memory and a 750GB hard drive can't elevate the system much higher.
