weaknesses/general Flashcards
List three key features of Von Neumann archicture.
- Memory is organized into addressable read/write storage locations.
- Memory contains both data and instructions
- Programs are executed sequentially using the Fetch-Execute cycle
What is “computer architecture”?
The conceptual design and functional behavior of a computer system.
What two key points best characterize an operating system?
- Manages hardware resources and provides an interface for applications.
- Achieves resource sharing through time and space multiplexing.
Which approach polling or interrupts, is more efficents for real-time systems and high I/O devices?
Interrupts are more efficient for real-time systems and high-speed I/O devices because they allow the CPU to perform other tasks and respond to events only when an I/O device requires attention, minimizing wasted CPU cycles and enabling better multitasking
What is the range of digits in a base 14 number system?
0, 1, 2, . . . , 9, A, B, C, D
we will always have one less than our base (which is why E is not included)
note: for any base above 10, we use the convention: A = 10, B = 11, C = 12, …
What is the usage of Base 2 (binary) numbers?
Core of computing (bits, logic circuits)
What is the usage of Base 8 (octal)
Older computing systems, shorthand for binary
what is the usage of Base 10 (Decimal)
Human everyday use
What is the usage of Base 16 (Hexadecimal)
Memory addresses, colors, networking
