Memory Card

                 A Memory Card is commonly known as a multimedia memory card. It is
                 very small in size, usually 1–1.5 inches. These are used in mobile phones
                 and digital cameras. You need to have a card reader to read the stored
                 data on the memory card.

                 Measuring the Computer’s Memory

                 The basic unit for measuring the memory of a computer is the byte. A byte consists of a

                 group of eight bits, for example, 10001011, that is, 1 byte equals 8 bits. A group of 4 bits is
                 known as a nibble (half a byte), for example, 1001, that is, 1 nibble equals 4 bits.
                 Other  units  for  measuring  the  computer’s  memory  are  Kilobyte,  Megabyte,  Gigabyte,

                 Terabyte, and so on.
