Memory And Memory Of Computers - 868 Words

Memory Have you ever wanted to know how certain files, documents and so on are being saved and what led this to occur? The memory of computers is quite fascinating and there is so much that goes into saving something on a computer. There are different types of memory that is found on computers that is needed to make things work and that would be acceptable to the user. The main two that is quite known in the computer world would be Primary and Secondary memory. There are 2 types that make up the Primary memory and that would be Random Access Memory (RAM) and Read only memory (ROM). The secondary memory consists of a hard disk drive, flash drive and zip drive. There are also optical discs that are included. One thing that is special in terms of computers would be the Primary memory. Primary memory is divided into 2 types. The first type would be random access memory. RAM is in charge of keeping data in a stored area so that it can be reached by the processor when necessary. RAM does a really good job at laying away data in such a random basis. An article from the PC World have shown that in this generation RAM has increased tremendously; it is said that â€Å" A review of systems that the PC World test center has grown from a little over 90 MB to about 2 GB, spiking whenever Microsoft releases a new version of Windows† (Stafford pg. 84). RAM has 2 forms, they are Static RAM and Dynamic RAM.

If your computers CPU had to constantly access the hard drive to retrieve every piece of data it needs, it would operate very slowly. When the information is kept in memory, the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily. As you can see in the diagram above, the CPU accesses memory accordingRead MoreComputer Memory2193 Words   |  9 PagesA. VOLATILE MEMORY Volatile memory, also known as volatile storage, is computer memory that requires power to maintain the stored information, unlike non-volatile memory which does not require a maintained power supply. It has been less popularly known as term Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitorRead MoreComputer Memory3238 Words   |  13 PagesComputer Memory 1.Introduction: Just like humans, computers rely a lot on memory. They need to process and store data, just like we do. However, computers store data in digital format, which means the information can always be called up exactly the way it was stored. computer memory - an electronic memory device; a memory and the CPU form the central part of a computer to which peripherals are attached 1.1History of memory: In the early 1940s, memory technology mostly permitted a capacityRead MoreComputer Science : Memory Management1149 Words   |  5 Pages Memory Management Navid Salehvaziri Virginia International University â€Æ' Abstract Memory management is a field of computer science that involves the act of managing computer memory to use it more efficient. That means how the computer allocate portion of memory to programs at different levels of priority to make faster program execution regard to memory space limitation. There are many techniques that are developed to reach this goal at many levels. This article try to introduce memory managementRead MoreComputer Memory Hacking Essay908 Words   |  4 PagesComputer Memory Hacking NAME Professor CIS 106 November 20, 2014 Technology continues to evolve exponentially. However these technological advancements continue to pose a threat to both individuals and information resources of companies and governments. There is therefore the need to protect one’s data and information due to the emerging threats and risks. Hacking is where third parties create a backdoor version of a hardware and software so as to manipulate or unlockRead MoreComputer Memory Hacking Essay835 Words   |  4 PagesComputer  Memory  Hacking                      Computer  Memory  Hacking   Rebecca  M.  Shepherd   CIS  106  Intoduction  to  Information  Technology   Professor  Dima  Salman   Stayer  University  Ã‚   November  23,  2014                                 Computer  Memory  Hacking    Hacking  of  memory  or  hacking  of  RAM  describes  when  a  person  or  person(s)  gains   unauthorized  access  to  the  RAM  (random  access  memory)  of  a  computer  system.  There  a  couple   of  reasons  that  one  might  participate  in  hacking  the  memory  of  a  computer  system.  One  reason  Read MoreThe Computer Memory Interference Test Essay1356 Words   |  6 PagesIntroduction The Computer Memory Interference Test (CMIT) is a test that is designed to evaluate how memory is affected by a myriad of different variables. With results from this test, scientists are able to determine if an individual has a serious memory disorder such as Alzheimer’s, or other cognitive disorders such as Autism. This test can also determine how memory is affected by different cultures and lifestyles. This study will concentrate on lifestyle; more specifically, it will focus on theRead MoreAn Array Is Stored In A Continuous Sequential Memory Computers762 Words   |  4 Pagesrepresented in a larger format requires more complex circuitry and more time for executing the codes.

This takes place when a process or programme writes or attempts to write data onto a static sized memory block than it was initially allocated. By taking advantage of the buffer overflow attacker are always aiming to completely take control of the whole system by elevating their privileges to the Admin rights. To successfully attain this they identify a function pointer in memory that theyRead MoreEffects Of Computers On Memory : Cognitive Consequences Of Having Information At Our Fingertips1045 Words   |  5 PagesEffects on Memory: Cognitive Consequences of Having Information at Our Fingertips†, was written by Betsy Sparrow, Jenny Liu, and Daniel M.
