Question

Accepted Answer

Explanation of 8051 architecture, memory, register banks, and RTOS.

8051 architecture consists of CPU, RAM, ROM, Timers, Serial Port, Interrupts, and I/O ports.
Harvard architecture has separate memory for instructions and data, while Von Neumann architecture has a single memory for both.
RISC architecture has simple instructions and fewer addressing modes, while CISC architecture has complex instructions and more addressing modes.
8051 has 128 bytes of RAM and 4 KB of ROM.
8051 has four register banks, each containing eight registers.
RTOS is a real-time operating system that schedules tasks based on priority or time-slicing.
Round robin scheduling assigns equal time slices to each task, while daisy chain scheduling assigns priorities to tasks based on their order in the chain.
