Quiz_________________?
Abstraction -
Answer✅
An OS technique that combines simpler operations into more complex ones, hiding
implementation details to simplify interaction between hardware and users. (C191 Section
1)
Quiz_________________?
Access List (AL) -
Answer✅
An implementation of the access matrix associated with each object, specifying which
domains may perform which operations on that object. (C191 Section 16)
Quiz_________________?
Access Matrix -
Answer✅
A conceptual framework representing the access rights of each domain (user or process)
over each object (file, device) in the system, used as the basis for implementing access
control. (C191 Section 16)
Quiz_________________?
Alarm Clock Problem -
2
, Answer✅
A monitor-based synchronization scenario where threads wait for a set amount of time
before proceeding, using priority waits to manage waking order based on alarm settings.
(C191 Section 5)
Quiz_________________?
Amdahl's Law -
Answer✅
A formula that illustrates the potential performance gains from adding additional computing
cores to an application with both serial and parallel components. (C191 Section 3)
Quiz_________________?
API (Application Programming Interface) -
Answer✅
A set of commands and functions that allows programming applications to interact with the
operating system. (C191 Section 2)
Quiz_________________?
Application State -
Answer✅
A construct used in mobile operating systems to save an application's current state so it can
be quickly restored after being terminated due to low-memory conditions, without the user
experiencing a full restart. (C191 Section 9)
Quiz_________________?
Automatic vs. Manual Mounting -
3
, Answer✅
A distinction in how partitions are made available: the root partition is mounted
automatically at boot, while other partitions may be mounted automatically via configuration
files or manually by an administrator at any time. (C191 Section 15)
Quiz_________________?
Back Door (Trapdoor) -
Answer✅
A hidden mechanism bypassing normal user authentication, potentially inserted by a systems
programmer to allow unauthorized access to a system. (C191 Section 16)
Quiz_________________?
Backing Store -
Answer✅
Secondary storage (such as a hard disk or SSD) used to temporarily hold processes or pages
that have been swapped out of main memory. (C191 Section 9)
Quiz_________________?
Basic File System (Block I/O Subsystem) -
Answer✅
The file-system layer responsible for issuing generic read and write commands to device
drivers for specific blocks on the storage device, and for managing memory buffers and
caches. (C191 Section 14)
