Windows being 32 or 64 bit has to do with the width of the address bus not the data bus. This is a very good video none the less.

@uttamkumarsingh2465 3 ай бұрын

Is it 65536 bits or bytes ?? I guess it shall be 65536 bits.

@uttamkumarsingh2465 3 ай бұрын

You are confused. Address bus is of 16 bits. Hence it can access 65536 memory location in the storage or memory device. Each location of the memory can store 1 byte of data, which means 65536 memory location can store 65536 bytes of data.

@TheGrezly 3 ай бұрын

Byte

@muhammedguveloglu2084 2 ай бұрын

Answer is "bytes". In the video , example has 16 bits wide adress bus and 8 bits wide data bus system. 65536 x 8 bits (1 byte ) memory at one memory module.

Depends on data bus. If it's an 8bit bus, then 1 byte can be read at a time.
