The computer environment static and dynamic memory helps to work with a lot of information.The first of them is used for storing small amounts of data.Its principle of operation is similar to a simple switch contacts close when an electric current passes freely conclusions of the memory cell.Computer, meanwhile, sees it as a logical unit.And, accordingly, the reverse reaction occurs when the contact is open.The first memory to a computer containing the special relay switches are used as cells.In our time the cell chips are conventional conductors, a number of which are being destroyed at a special programming devices.Such circuits often act as a permanent storage device.
Dynamic memory based on the ability of two conductors which are at a certain distance from each other, recruit and retain the electric charge.The cell in this case is represented by a tiny capacitor having insulating spacers between the electrodes.When a supply of electricity, one of the electrodes accumulates positive potential and the other - the stock collects negative direction.The computer senses the presence of the charge on the output as one bit.Each cell has a permanent address, by which the controller fails to read information.
However, the time in which microscopic capacitors will be able to maintain the charge is actually very little and makes some milliseconds.In this regard, the dynamic memory requires constant recharging, updating the operating space.It has a total energy dependence, so the blackout cells cease to be updated.There is a discharge of capacitors, and all data is destroyed.A distinctive feature of this type is the high performance that the modern computers is especially prized.Dynamic memory found its application in the computer field as random access memory.
Although it is believed that the success of microelectronics and innovative actions in the development of micro-processors made it possible to present the performance of personal computers, in fact played an important role dynamic memory.It had a direct impact on the programming, creating a visual way.Yet it is worth noting that its cells are susceptible to the radiation background and the quality of supply.Thus, additional trouble deliver alpha particles and cosmic rays.Although in today's world still manages to produce reliable data protection and distortion of information could be counted on the fingers.However, an absolute guarantee against data corruption can not give one.His recognition of the dynamic way of storing information was largely due to the density of the cells.
