Memory: Your memory does not store everything forever. The computer memory refers to computer components, devices and recording media that retain digital information. The computer data storage provides one of the core functions of a computer that of information retention. How a Computer Remembers: A computer has two memories, called RAM and ROM. ROM stands for Read Only Memory. It carries the information. The computer needs to carry out, it’s task, and it cannot be altered. It stays there even when the computer switch off. RAM stands for Random Access Memory or Read and Write Memory. This contains the information the computer needs to carry out the particular task you want. When you switch off the computer, RAM empties itself. You can save your work on CD-ROM, DVD ROM Disk, Floppy Disk, Flash Drives, etc. Storing Information: Each memory cells stores binary digits. It is easy to see that the size of computers RAM is important because the computer can only do the amount of work that it has room for. Computer Memory Memory Imagine that you are going to the park to play with your friends. You know the way because you have been there before. The route is stored in your memory. On the way, you meet someone and stop for a chat. If it’s not about anything important, you will probably soon forget. Your memory does not store everything forever. The computer memory refers to computer components, devices and recording media that retain digital information used for computing for some interval of time. The computer data storage provides one of the core functions of a computer, that of information retention. How a Computer Remembers A computer’s memory works in similar way. There are some pieces of information that need to be stored away. Others can be forgotten once the computer has worked on them. To separate the two types of information, a computer has two memories called ROM and RAM. ROM stands for Read Only Memory. ROM carries the information the computer needs to carry out its task. This information is built into the computer and cannot be altered. It stays there even when the computer is switched off, just as your memory of how to get to the park stays with you until you need it again. RAM stands for Random Access Memory, or read and write memory. This contains the information the computer needs to carry out the particular task you want it to do now. When you switch off the computer, RAM empties itself. You can save your work on CD-ROM. DVD ROM disks, floppy disks, flash drives, etc. Storing Information ROM and RAM are both made up of memory cells, Each memory cell stores binary digits. A chip may be able to store millions of bits. It is easy to see that the size of the computer’s RAM is important because RAM has room for it. With some computers, it is possible to add extra memory chips to increase the RAM.
