IT 342 EXAM 1 GMU 2025 QUESTIONS
AND ANSWERS
What is Abstraction? - ANS Handle very complex problems and systems while also hiding the
details from the user.
What is a batch? - ANS A batch is a set of similar processes that are group together and
processed one after another to maximize system performance.
What is a batch OS? When is this OS best used? - ANS An operating system that uses some
sort of batch processing.
Best for systems that do not require human interaction. They have humans send jobs and the
OS does the rest.
What is bootstrapping? - ANS This occurs when the computer boots up and the OS is loaded
to the main memory of the system

,What is cache? - ANS Cache is very fast memory stored close to the CPU to reduce time for
functions that are used often.
What is Character user interface? (CUI) - ANS All commands need to be typed by the user to
make the OS function. Different than a GUI, which uses graphical interface.
What is a CPU? - ANS Central Processing Unit; the brain of the computer.
What is CPU-bound? - ANS These a programs bound to the CPU that require a lot of
processing power to complete.
What is a distributed OS? - ANS This is when several physical processors are connected to
allow large computational applications to be split up and processed by different processors,
making the task much faster to complete.
After each processor has finished his part of the work, they send it back to the main processor
to have it put back together

, What is an operating system? - ANS collection of software that manages computer hardware
resources to provide services.
What are the goals of an operating system? (3) - ANS 1. Efficient use of computer hardware
2. Provide the user with user friendliness
3. Hide complexity of computer hardware
What is an OS interface? - ANS The way the user interacts with or uses the operating system.
Usually CUI or GUI
What are the step of a booting process? - ANS Power button on computer
CPU pins are reset
registers in cpu change value
control unit of cpu jumps to BIOS
BIOS and POST are run
