Out of so many machines discovered till now the major machine which governs the human totally at the present period is the computer.
Normally based around semiconductor technology, memory is used in any equipment that uses a processor of one form or another. Indeed as processors have become more popular and the number of microprocessor controlled items has increased so has the requirement for semiconductor memory.
An additional driver has been the fact that the software associated with the processors and computers has become more sophisticated and much larger, and this too has greatly increased the requirement for semiconductor memory. In view of the pressure on memory, new and improved semiconductor memory technologies are being researched and development can be very rapid.
Nevertheless, the more mature semiconductor memory technologies are still in widespread use and will remain so for many years to come.
In addition to this new applications such as digital cameras, PDAs and many more applications have given rise to the need to memories.
Accordingly it is not uncommon to see semiconductor memories of 8 Gbyte and much more required for various applications. An example of semiconductor memory technology used in computers With the rapid growth in the requirement for semiconductor memories there have been a number of technologies and types of memory that have emerged.
Each one has its own advantages and area in which it may be used. Types of semiconductor memory Electronic semiconductor memory technology can be split into two main types or categories, according to the way in which the memory operates: As the names suggest, the RAM or random access memory is a form of semiconductor memory technology that is used for reading and writing data in any order as required.
It is used for such applications as the computer or processor memory where variables and other stored and are required on a random basis. Data is stored and read many times to and from this type of memory.
A ROM is a form of semiconductor memory technology used where the data is written once and then not changed. In view of this it is used where data needs to be stored permanently, even when the power is removed - many memory technologies lose the data once the power is removed. As a result, this type of semiconductor memory technology is widely used for storing programs and data that must survive when a computer or processor is powered down.
As the name implies, data cannot be easily written to ROM. Although it is often possible to change the data, this gain requires special hardware to erase the data ready for new data to be written in.
Both of these categories of semiconductor technology are widely used. Each type being used in different areas and applications within microprocessor based electronics systems. These arise from the variety of applications and also the number of technologies available.
This stands for Programmable Read Only Memory. It is a semiconductor memory which can only have data written to it once - the data written to it is permanent.
These memories are bought in a blank format and they are programmed using a special PROM programmer. Typically a PROM will consist of an array of fuseable links some of which are "blown" during the programming process to provide the required data pattern.The data storage capacity of the data center depends on various types of storage devices.
There are three types of storage devices, including three types of hard disks (SSD; HHD; HDD). Solid State Drive. A hard disk made of a solid-state electronic memory chip array is composed of a control unit and a memory unit (FLASH chip, DRAM chip).
Android vs iOS comparison. Google's Android and Apple's iOS are operating systems used primarily in mobile technology, such as smartphones and tablets. most commonly used smartphone platform and is used by many different phone manufacturers.
iOS is only used on Apple devices, Native integration with Google cloud storage. 15GB free, $2. Practical comparison of three principles for the extraction of residual pyrethroids from aqueous matrices: Relative merits and demerits. PRIMARY MEMORY. MALINI MOHAN S1 MBA Memory is a part of computer system that is used for the storage and subsequent retrieval of data and instructions.
The computer has to store the data to be processed, instructions for and results after data processing. A hard disk drive or HDD is a data storage device that uses magnetic recording to store and retrieve digital information SOCIETY AND CULTURE; VERSION SPOTLIGHT; Browse Topics; HDD: Advantages and disadvantages of hard disk drive.
Posted on May 5, May 5 The stark difference between a hard disk drive and a solid-state drive also. Merits And Demerits Of Diff Storage Devices.
