Technology is increasingly important at today's colleges and universities, and Harvard certainly realizes that. Students have access to a number of computer labs, and every upperclass house has its own computer lab in the basement. Students benefit from a high-speed Ethernet network, as well as the Wi-Fi (wireless) network.
Despite these positive highlights, the majority of students recommends that you provide your own computer. Access to computer labs tends to be a weakness because of overcrowding, and having to print out an assignment at the last minute can be nerve-wracking when you are waiting for a computer to open. The hardware is there, just be patient and factor waiting time into your schedule if you plan on relying on Harvard's computer labs.
