Data Storage

Get to know more about computer data storage.


The main purpose of data storage devices in computers is to retain information. Information retained is the core to the functioning of the CPU and other computer parts. CPU functions by manipulating data stored in primary storage media like registers and RAM. Information stored in secondary media like hard disks and optical disks is also required for the proper functioning of the computer.


Generally, storage of data in a computer has an impact on the following:




  • Performance

  • Reliability

  • Power consumption



Performance



With today’s fastest data storage components, computer performance in terms of speed and efficiency has greatly been increased. It takes a mere nanosecond with today’s fastest RAM’s for the CPU to manipulate data stored in the RAM. As for data stored in the hard disks and other disks they can be manipulated in milliseconds.


Ultra fast registers a feature of today’s computers have generally increased performance of computers. The cache memory is also a form of data storing component in a computer. The cache memory boasts the speed by which computer operations are carried out by storing a duplicate of the most used information of main memory.


A computer’s performance is also far more enhanced than that of calculators and other computer like devices because of the processor registers. These registers are responsible for storing data used for calculations and other arithmetic and logic functionalities.



Reliability



Solid-state silicon chips used in the present data storage devices makes them more reliable. With these data can safely be stored without the risk of being damaged or lost. Reliability of data storing components can also be looked at from the perspective of their portability. Hard disks of today are small and light and can easily be carried in a bag. As for optical disks and flash disks, they can be contained in a pocket. Despite the small sizes of these devices, they can still be trusted with storing large volumes of information.



Power consumption


Less power consumption by the data storage devices implies more benefits to the environment. Primary data storing devices would, as a matter of fact, shut down automatically when they are not in active use. This enables conservation of power. Secondary devices require power only when data is being inserted into them or accessed. Otherwise they store and maintain data in them without the use of any power.


The process of data storing in a computer is an energy efficient process in comparison to other operations in a computer. Operations like functioning of the CPU do require hefty amounts of power.


It is accurate to conclude that data storage devices do boast the performance and reliability of computers. When it comes to power consumption, storing of data doesn’t need much power.
