Which type of memory is the main memory installed as DIMMs on a motherboard?
DRAM
The main difference between sdram and dram is that dram is?
The main difference between Synchronous random access memory, SDRAM and Dynamic Random Access Memory, DRAM is that SDRAM is synchronous while DRAM is asynchronous. As such, SDRAM is efficient in retrieving and storing data than DRAM.
What are the two main types of ram memory sram and dram?
DDR and DDR2
State the two major categories of RAM?
The two major categories of RAM are dynamic RAM (DRAM) and static RAM (SRAM). DRAM is cheaper and used for main memory in computers, while SRAM is faster but more expensive and is used in caches or for smaller, high-speed memory.
Draw the block diagram of ram and explain its operation?
Memory is technically any form of electronic storage. Personal computer system have a hierarchical memory structure consisting of auxiliary memory (disks), main memory (DRAM) and cache memory (SRAM). A design objective of computer system architects is to have the memory hierarchy work as through it were entirely comprised of the fastest memory type in the system.
What is your computer's main memory that holds programs data and instructions currently in use for quick access by the processor?
The computer's main memory is called Random Access memory(RAM). RAM is where the currently running programs reside.However, let's clear up one thing. There is an even faster type of RAM which is in the CPU itself, and that is cache memory. While modern dynamic RAM (DRAM) is fast, it still isn't as fast as the fastest static RAM. DRAM constantly has to be refreshed, while SRAM doesn't. However, SRAM is more expensive and uses more power. So as a compromise, there are special high-speed memory areas known as cache memory that stores the most used instructions and data as to reduce the amount of system RAM access. Since it is inside the CPU and is static memory, it is quite faster than the system DRAM memory.So while the system DRAM memory contains all the operating programs, the SRAM caches in the CPU contains things that are more immediate or are used more often.
What is the Difference of sram and dram in term of application?
both are semiconductor memory. semiconductor means that both need continuous voltage or charge to sustain their data. SRAM used for cache , and store data in the flip flop, no need for refreshing , fast access but more expensive. DRAM used for main memory , and store data in capacitor, need for refreshing , slow access but less expensive.
Most systems don't use SRAM for main memory because?
SRAM is static RAM. It does not need to be refreshed like DRAM. Although it is faster than DRAM it is also very expensive. So it is not used computer prices would triple. Don't get that confused with SDRAM...that's a whole different story.
What is the need of cache in computer?
Definition from webopedia: portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because most programs access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM. So basically, to have a faster form of RAM for data to be stored in to so the CPU doesn't have to constantly write and re-write into DRAM. Also distance plays a factor in the speed to the access times. Cache is either on or in between the the slower DRAM. The shorter the distance the faster the access times.
What is the use of virtual memory?
Virtual memory is used to increase the size of working memory in the system main memory by using the locations in secondary storage such as harddisk.
Can you use capacitor as a memory device?
Yes you can, in fact I almost guaruntee you did to write the question - the RAM in your computer is likely DRAM, or dynamic random access memory, which uses capacitors to store bits. The problem with using capacitors is there is always some leakage current flow, which results in slowly draining the capacitor's voltage. To prevent the loss of data, DRAM continuously "refreshes" itself by measuring whether the capacitor is charge or not, and fully charging it if it is considered a logical '1'. The capacitor's voltage will again slowly drain off until the next refresh cycle. The main benefit of this type of memory over more static, gate based memory is it is very cheap, and easy to manufacture.
What are the disadvantages of using wind turbine to generate electricity?
Lack of wind is the main disadvantage.
