Storage capacity refers to how much disk space one or more storage devices provides. It measures how much data a computer system may contain. For example, a computer with a 500GB hard drive has a storage capacity of 500 gigabytes. A network server with four 1TB drives, has a storage capacity of 4 terabytes. A single byte stores eight bits1 Kilobyte =1 thousand or, 103 bytesTherefore 5KB =5×103 bytesMegabyte= 1 million or 106 Bytes1500 MB=1500×103 bytes=15×105 bytesGigabyte =1 billion, or 108 BytesTerabyte =1 trillion, or 1012 Bytes2 TB=2×1012 Bytes?Hence the correct answer is (B), (C), (A), (D) Additional InformationIn computer systems, a unit of data that is eight binary digits long is known as a byte. A Terabyte (TB) is a measure of computer storage capacity. It equals approximately a trillion bytes. The largest storage capacity is called 'Yottabyte'
