Primary memory: The primary memory or the main memory is part of the main computer system. The processor or the CPU directly stores and retrieves information from it. This memory is accessed by CPU, in random fashion. That means any location of this memory can be accessed by the CPU to either read information from it, or to store information in it. Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and floppy disks. The hard disk has enormous storage capacity compared to main memory. The hard disk is usually contained in the systems unit of a computer. The hard disk is used for long-term storage of programs and data. Data and programs on the hard disk are organized into files--named sections of the disk. A hard disk might have a storage capacity of 40 gigabytes. This is about 300 times the amount of storage in main memory (assuming 128 megabytes of main memory.) However, a hard disk is very slow compared to main memory. The reason for having two types of storage is this contrast: Primary memory : 1) Fast 2) Expensive 3) Low capacity 4) Connects directly to the processor Secondary Memory : 1) Slow 2) Cheap 3) Large capacity 4) Not connected directly to the processor *Floppy disks are mostly used for transferring software between computer systems and for casual backup of software. They have low capacity, and are very, very slow compared to other storage devices. Primary memory is much faster and also it is more cost effective. But the secondary memory is much slower and also less costly. It stores the data permanently unless it is erased. The secondary memory is usually available in the form of floppy disk storage media, hard disk, CD, DVD, Pen drive (i.e. Mass storage devices), memory chips. A 5 and1/4 inch floppy disk typically stores 1.44 mb of data. The data on the floppy disk is organized in terms of tracks and sectors. Hard disk can have large capacity something like 80-300 GB's or higher. Hard disk itself is made up of, large number of platters. Hard disk is usually much faster compared to floppy disk. CD can store up to 750 mb of data. Information on CD ROM is organized in terms of a spiral track. A DVD is digital Versatile Disk and can store 4.6 Gigabyte of information. All these CD disk are usually write ones and read many times (if the disk is not multisession and re writable). So are the DVDs.

why??
mathslover
  • mathslover
videos in power point presentation .. :( Power point should be explained by you ! ..why to explain by any one else ..
AravindG
  • AravindG
i jst need video of hard disk running ,data storage etc i will explain!!!
mathslover
  • mathslover
you will just have a picture and then u will communicate... You can not teach through videos but u can learn oh ! i got it now !! you mean some practicals of these machines or devices ?
AravindG
  • AravindG
yep!!!
AravindG
  • AravindG
yep why dont my audience see these devices working animation etc that would make working much clearer!!

This memory is accessed by CPU, in random fashion. That means any location of this memory can be accessed by the CPU to either read information from it, or to store information in it. o The primary memory itself is implemented by two types of memory technologies. The first is called Random Access Memory (RAM) and the other is read only memory (ROM). A more appropriate name for RAM is RWM (Read Write Memory), the CPU can write and read information from any primary memory location implemented using RAM. The other part of primary memory is implemented using ROM which stands for Read Only Memory. Primary memory is much faster and also it is more cost effective. But the secondary memory is much slower and also less costly. It stores the data permanently unless it is erased. The secondary memory is usually available in the form of floppy disk storage media, hard disk, CD, DVD, Pen drive (i.e. Mass storage devices), memory chips.
