Virtually all contemporary computer designs are based on
Concepts developed by John von Neumann at the
Institute for Advanced Studies, Princeton. Such a design is referred
to as the von Neumann architecture and is based on three key
concepts:
■ Data and instructions are stored in a single read–write memory.
■ The contents of this memory are addressable by location, without
regard to the type of data contained there.
■ Execution occurs in a sequential fashion (unless explicitly
modified) from one instruction to the next.

What Is Firmware?
Firmware is a form of microcode or program
embedded into hardware devices to help them
operate effectively. Hardware like cameras, mobile
phones, network cards, optical drives, printers,
routers, scanners, and television remotes rely on
firmware built into their memory to function
smoothly.
There
are typically three levels of firmware:
1.Low-level firmware: This firmware is usually stored in non-volatile memory chips like
read-only memory (ROM) and one-time programmable (OTP) memory. These chips
cannot be rewritten or updated, and the firmware is intrinsic to the hardware, such as a
computer.
2.High-level firmware: This firmware is deployed within flash memory chips and comes
with more complex instructions that allow updates to be made.
3.Subsystems: These are semi-independent devices that are part of a more extensive
system. Firmware at this level is embedded within central processing units (CPUs),
flash chips, and liquid crystal display (LCD) units.

What is an instruction cycle?
The instruction cycle (the main instruction cycle) is a fundamental
sequence of steps that a CPU performs. Also known as the "fetchexecute cycle," it is the process whereby a single instruction is
executed. The first half of the cycle transfers the instruction from RAM
to the instruction register (fetch) and decodes it. The second half
executes the instruction.
