Computer Science, Master of Science

A focus area or concentration must be chosen for this program.

Admission Requirements

Applicants (degree seeking and special student) must meet the general requirements for admission to graduate study. The applicant's prior education must include the following prerequisites:

1. One year of calculus (2 semesters or 3 quarters);
2. One semester/term of advanced math (discrete math is strongly preferred but linear algebra and differential equations will be accepted);
3. One semester/term of Java (C++ will be accepted but the student must be knowledgeable in Java);
4. One semester/term of data structures;
5. One semester/term of computer organization (e.g., assembly language and machine organization).

Applicants whose prior education does not include the prerequisites listed above may still enroll under provisional status, followed by full admission status once they have completed the missing prerequisites. Missing prerequisites may be completed with Johns Hopkins Engineering (all prerequisites are available) or at another regionally accredited institution. Admitted students typically have earned a grade point average of at least 3.0 on a 4.0 scale (B or above) in the latter half of their undergraduate studies. Applicants may submit a detailed resume if they would like their academic and professional background to be considered.

Program Requirements

Ten courses must be completed within five years. Students are required to choose a focus area to follow. The curriculum consists of three foundation courses and five courses from the Computer Science program, which includes selected courses from other programs as indicated in the course lists below. At least three courses must be from the same focus area, at least three must be at the 700-level, and at least one 700-level course must be in the chosen focus area. Up to two electives may be selected from outside the Computer Science program and require prior advisor approval. Transfer courses will be considered electives. Transfer courses must meet all general Engineering for Professionals requirements for transfer, must be directly applicable to Computer Science, and will be considered on a case-by-case basis. Only one C-range grade (C+, C, or C–) can count toward the master’s degree. All course selections outside of the Computer Science program requirements are subject to advisor approval.

Non-degree students in Computer Science should consult with their advisor to determine which courses must be successfully completed before 600- or 700-level Computer Science courses may be taken.

Concentration: Communications and Networking

Ten courses must be completed within five years. The curriculum consists of three foundation courses from the program and seven concentration courses as listed in the Courses by Concentration section, of which a maximum of three may come from the Elec­trical and Computer Engineering (EN.525.xxx) program. Students are strongly encouraged to take courses from both Computer Science and Electrical and Computer Engineering. Only one C-range grade (C+, C, or C–) can count toward the master’s degree. 

Students lacking an electrical engineering background or equivalent must take EN.525.202 Signals and Systems as an undergraduate prerequisite before taking Electrical and Computer Engineering communications and networking courses.

Concentrations are noted on the student’s transcript.

²

Students working toward a master’s degree in Computer Science are required to take the following three foundation courses before taking any other courses.

³

One or more foundation courses can be waived by the student’s advisor if a student has received an A or B in equivalent graduate courses. In this case, the student may replace the waived foundation courses with the same number of other graduate Computer Science courses and may take these courses after all remaining foundation course requirements have been satisfied.

⁴

Some courses require fulfillment of Artificial Intelligence program prerequisite courses. 

⁵

Some courses require fulfillment of Data Science program prerequisite courses. 

Courses by Focus Area

The focus areas offered represent related groups of courses that are relevant for students with interests in the selected areas. Students are required to choose a focus area to follow and to take at least three courses from the selected focus area, including at least one 700-level course. The focus areas are presented as an aid to students in planning their course selections and are only applicable to students seeking a master’s degree. They do not appear as official designations on a student’s transcript or diploma.
