Explain the 'clock' component of CPU. How many bytes of data can be stored in a 16 GB pen drive ?

One of the important components of a CPU is the "clock." The clock produces a signal that acts to synchronize the logic units within the CPU as they execute the instructions given in a program. The CPU Clock speed refers to the number of times that a CPU's clock cycles per second. A "cycle" is technically a pulse synchronized by an internal oscillator, but in common language they're a basic unit that helps understand a CPU's speed. Typical computers have a clock speed around 2.8 GHz (Gigahertz), which means that the clock cycles 2.8 billion times a second, and execute an equivalent number of instructions. A computer memory consists of several electronic cells. Each cell is capable of storing a byte. The smallest unit of data that can be stored is a binary digit 'bit', 8 bits come together to create a 'byte'. 1KB = 1024 Byte 1 MB = 1024 KB 1 GB = 1024 MB Hence, the bytes of data that can be stored in a 16 GB pen drive is calculated as under: 16 GB = 16 x 1024 MB = 16 x 1024 x 1024 KB = 16 x 1024 x 1024 x 1024 bytes = 17,17,98,69,184 bytes However practically in devices available in market the entire 16 GB storage is not entirely available, the space available is around 14.8 GB in a 16 GB pendrive.
