Every application a user runs depends on the operating system correctly managing shared hardware resources among competing processes — IT2180 teaches how that management actually works.
Process and memory management
IT2180 covers how operating systems manage multiple running processes simultaneously through scheduling algorithms, and how memory management (virtual memory, paging) allows more processes to run than would fit in physical RAM alone, while preventing one process from corrupting another's memory space.
Storage and hardware infrastructure
The course covers file systems and storage management, and surveys hardware infrastructure considerations relevant to IT professionals — server hardware specifications, RAID storage configurations for redundancy, and basic hardware troubleshooting and maintenance practices used in enterprise IT environments.
Key topics in IT2180
- Process scheduling algorithms and multitasking
- Virtual memory and paging: running more processes than fit in physical RAM
- Memory protection: preventing processes from corrupting each other
- File systems and storage management fundamentals
- RAID configurations for storage redundancy and performance
- Enterprise hardware infrastructure basics and troubleshooting

Worked example: why virtual memory allows more programs to run than fit in RAM
- Physical constraint: A computer has 8GB of physical RAM, but the user has multiple large applications open needing a combined 12GB
- Virtual memory solution: The OS uses paging to move less-actively-used memory pages to disk storage temporarily, freeing physical RAM for actively used data
- Trade-off: Accessing paged-out data from disk is much slower than RAM, which is why excessive paging ("thrashing") causes a noticeably sluggish system
- Lesson: Virtual memory extends effective capacity but at a real performance cost when overused

Frequently asked questions
Physical memory (RAM) is the actual, finite hardware installed in a computer that provides fast, direct access to data actively being used by running processes. Virtual memory is an abstraction the operating system creates that gives each process the illusion of having access to a large, contiguous block of memory, even though the actual data may be spread across physical RAM and temporarily stored on disk when RAM capacity is exceeded. IT2180 teaches this distinction because virtual memory is what allows a computer to run more processes, or larger processes, than its physical RAM alone would support — the operating system uses paging to move data between RAM and disk storage as needed, transparently to the running application, though this comes at a real performance cost since disk access is dramatically slower than RAM access, which is why excessive reliance on virtual memory (thrashing) causes a system to become sluggish.
Without memory protection, one running process could accidentally or maliciously read or overwrite another process's memory space, causing crashes, data corruption, or serious security vulnerabilities — imagine a web browser tab crashing and, without proper isolation, corrupting the memory of an unrelated banking application also running on the same system. IT2180 teaches memory protection as a fundamental operating system responsibility because modern computers routinely run dozens or hundreds of processes simultaneously, many from different, mutually untrusting sources (different applications, different websites in different browser tabs, different users on a shared system) — the operating system's memory management unit enforces boundaries ensuring each process can only access its own allocated memory space, which is essential both for basic system stability and as a foundational security control preventing one compromised or malicious process from directly attacking another.
