The department makes use of a mix of computing platforms, with about three-quarters of our research and instructional computing taking place on Microsoft's Windows operating systems and Intel Architecture processors and the remaining quarter on Red Hat Linux desktop and Red Hat Linux and Sun Solaris back-end servers. The department has more than1,200 computers ranging from desktops to high-end parallel processing servers, more than 15 terabytes of online disk storage, and a backbone network based on switched Gigabit Ethernet.
The university provides extensive campus-wide networking, including RedRover, an 802.11b wireless campus network. National and international access is provided by three OC3 connections to the global Internet. High-speed community access is available through Time-Warner's RoadRunner cable modem system and several DSL providers. Finally, through the Cornell Theory Center and the Program in Computer Graphics, computer science researchers have access to a wide range of advanced parallel processing and supercomputer systems, as well as advanced graphics and visualization systems.
Each university in the Unites States of America sets its own admission standards so there isn't the same criteria for all the students and the university can decide which applicants meet those standards. The fee for each application is between $35 to $100.
After the selections of the universities you want to attend, the best of all would be to contact each university for an application form and more admission information for the international students. Moreover, for a graduate or postgraduate program it's necessary to verify the admission requirements. Some programs require that you send your application directly to their department.
Admissions decisions are based on students's academic record and different test scores, such as TOEFL, the SAT or ACT (for undergraduate programs) and GRE or GMAT (for graduate programs). Admission decision is based on your academic results and motivation.
