Required preparation
At the start of the course, students should have the ability to
- Use basic algebra, calculus, and probability (for performance analysis).
- Write simple imperative programs using lists, iteration, and array indexing for both read and write (mutable memory model).
- Describe data representations used by computer hardware at the bit level, operate on these representations, and compute their values.
- Explain the basic build process for computer software.
- Compare basic memory and I/O architectures, and how they can impact performance.
- Exemplify basic functionality and components of an operating system.
Learning objectives
At the end of the course, students should have the ability to:
- Recall, explain, and compare transmission media and access control schemes.
- Recall, explain, and compare addressing and message forwarding paradigms, including path computation.
- Recall, summarize, and exemplify connection management and reliable message transmission.
- Recall, explain, and compare naming and name resolution techniques, including mobility.
- Recall, summarize, and exemplify contemporary network protocols and techniques.
- Recall, summarize, and explain security/privacy concepts in network protocols and distributed systems
- Recall, explain, and compare high-level communication services and distribution services.
- Compare how existing distributed applications utilize services.
