Q1

Consider a computer with a $4 \mathrm{MHz}$ processor. Its $\text{DMA}$ controller can transfer $8$ bytes in $1$ cycle from a device to main memory through cycle stealing at regular intervals. Which one of the following is the data transfer rate (in bits per second) of the $\text{DMA}$ controller if $1 \%$ of the processor cycles are used for $\text{DMA}$?
