The department has access to the Lyle School of Engineering academic computing resources, consisting of shared-use computer servers and desktop client systems connected to a network backbone. All of the servers in the Lyle School of Engineering are running some variant of UNIX or Microsoft Windows. There is one primary file server that exports files using FNS or CIFS protocols. Each user, whether faculty, staff or student, has a “home” directory on the central file server. This directory is exported to other servers or desktop computers, regardless of operating systems, as needed. There are more than 40 servers whose purposes include the following: file service, UNIX mail, Exchange mail, firewall, UNIX authentication, NT authentication, printer management, lab image download, classroom-specific software, X windows service, news, domain name service, computational resources, and general use. This primary file server allows a user’s files to be used as a resource in both the UNIX and Microsoft PC environments. Almost all computing equipment within the Lyle School of Engineering is connected to the engineering network at 100 megabits and higher. The network backbone is running at a gigabit per second over fiber. Most servers and all engineering buildings are connected to this gigabit backbone network. The backbone within the Engineering School is connected to both the Internet 2 and the campus network that is then connected to the Internet at large. In addition to servers and shared computational resources, the Lyle School of Engineering maintains a number of individual computing laboratories associated with the departments. Specific department laboratory facilities for instruction and research include the following:

The undergraduate curriculum in electrical and computer engineering provides the student with basic principles through required courses, and specialization through a guided choice of elective courses.
Due to the extensive latitude in course selection and to the wide variety of courses available within both the Department of Electrical and Computer Engineering and the University as a whole, it is possible for the student to concentrate his or her studies in a specific professional area such as biomedical, engineering leadership, or smart wireless and embedded systems.
Each student may select one specialization or may personalize his or her degree by a particular choice of advanced major electives. Students should choose a specialization as soon as possible; however, for many students, this process continues from term to term as the individual becomes better acquainted with the discipline and with the choices available.
Students may pursue a second degree program in math or physics. Students wishing to obtain a second degree in mathematics or physics should contact the respective departments in Dedman College to discuss the requirements.
