A register stores a fixed number of bits, typically determined by the architecture of the computer system.

• The number of bits in a register can vary depending on the computer architecture.

• Common register sizes include 8 bits, 16 bits, 32 bits, and 64 bits.

• Registers are used to store data temporarily during processing.

• Example: In a 32-bit computer system, a register can store 32 bits of data.

The three types of addressing modes are immediate, direct, and indirect.

• Immediate addressing mode: The operand is directly specified in the instruction itself. Example: ADD #5

• Direct addressing mode: The operand is the address of the data. Example: ADD 500

• Indirect addressing mode: The operand is the address of a memory location that contains the address of the data. Example: ADD @500

Intensity of light can be checked using a lux meter or a photometer.

• Use a lux meter to measure the illuminance of a surface in lux units.
