Memory Card

                 Memory card  commonly known as a  multimedia memory
                 card, this storage device is quite small, typically ranging from
                 1 to 1.5 inches in size. It is frequently used in mobile phones
                 and digital cameras. To access the data stored on the memory
                                                                                                    Memory Card
                 card, you need a card reader.


                 Solid State Drive (SSD)
                 An  SSD is a  type  of  storage  device  that  holds information,
                 like  your pictures, games, and documents. An SSD  uses  the
                 technique of flash memory to store data. It is much faster than

                 a hard disk. SSDs are more durable and reliable than hard disks.                        SSD
                 They come in various capacities, typically 128 GB to several
                 TBs.  Nowadays,  desktop  computers  and  laptops  come with
                 SSD instead of traditional hard disk.

                  The pen drive was invented in 1998 by IBM.




                    MEASURING THE COMPUTER’S MEMORY

                 The fundamental unit for measuring computer memory is the byte. A byte consists
                 of eight bits and represents a single character of data. A group of four bits is called

                 a nibble, which is half a byte. Larger units used to measure computer memory
                 include Kilobyte (KB), Megabyte (MB), Gigabyte (GB), and Terabyte (TB).

                    1 Kilobyte (KB) equals 1024 bytes.
                    1 Megabyte (MB) equals 1024 KB.


                    1 Gigabyte (GB) equals 1024 MB.
                                                                         The human brain can hold about
                    1 Terabyte (TB) equals 1024 GB.                        2.5 Petabytes of information,
                                                                          equivalent to a TV show being
                    1 Petabyte (PB) equals 1024 TB.
                                                                           played for approximately 342
                    1 Exabyte (EB) equals 1024 PB.                                  years non stop.

                    1 Zettabyte (ZB) equals 1024 EB.

                    1 Yottabyte (YB) equals 1024 ZB.
