Computer technology refers to the storage capacity for information with its own special units. Each minuscule electrical switch is called a bit and can be off or on. As the information capacity of computers has increased, the industry has developed some much larger units based on the bit: 1 byte 8 bits 1 kilobit 210 bits, or 1024 bits (a kilobit is sometimes abbreviated Kbit) 1 kilobyte 210 bytes, or 1024 bytes (a kilobyte is sometimes abbreviated Kbyte) 1 megabit 220 bits, or 1,048,576 bits 1 megabyte 220 bytes, or 1,048,576 bytes 1 gigabyte 230 bytes, or 1,073,741,824 bytes a. How many kilobytes are there in a megabyte? Express your answer as a power of 2 and in scientific notation. b. How many bits are there in a gigabyte? Express your answer as a power of 2 and in scientific notation. 25.
