Semiconductor memory
Memory device operating speed is measured in cycle time which is the amount of time required for memory to perform read and write operation and return to its original state ready for next operaiton. Access time is another measure of memory speed which is only the time required for read operation or it is the time between data receiving (read operation) and the data becoming available at the memory output.
DDR2 memory with a speed of 667 MHz can be purchased online through Amazon, Newegg, and other companies that sell and ship computer accessories and electronics. One can also find it at local technology and electronics retail stores like Best Buy and Micro Center.
it adds power ( ability to process faster) which in turn adds over all speed
The slab allocator in operating systems manages memory allocation by dividing memory into fixed-size blocks called slabs. Each slab is dedicated to a specific type of data structure, such as a certain size of objects. When a request for memory allocation is made, the slab allocator assigns memory from the appropriate slab, reducing fragmentation and improving efficiency. This method helps to speed up memory allocation and deallocation processes in the operating system.
Ram, free memory, if it is compressed, if it is defregmeted lately, what operating of system, what battery settings you have, your internet connection, the temp. of CPU and the processors.
No the amount of memory (256mb) is too small to run most operating systems. The processor speed is ok and you could get external disk drive to store your data. 10gb is just enough for an operating system and maybe Office.
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
Speed(memory), or S(m)
the main memory is usually known as RAM.it stores the data & instructions currently needed by CPU but it operates at a very high speed.therefore, the memory should be fast otherwise there will be a speed mismatch between the two& it may led to the wastage of processing time of CPU.to overcome this a very fast memory CACHE MEMORY is placed between the two. so CACHE MEMORY is used to operate at the speed of CPU.it also increases the operating speed.
The most important thing to watch is that the mhz speed of the Ram matches the cpu operating freqeuncy. Not matching them can cause erratic behaviour of the CPU
Speed and quality (brand). PS: memory parameters are not directly connected to overclocking capabilities of CPU. Usually CPU itself is the major factor. Meaning that even if you have the best memory on the market but your CPU is not capable of overclocking you do get good results. And opposite if you have average quality memory but good CPU you can get very good results. There is one exception. When you overclock both CPU and memory both should be with a right speed and good brand.
Paging in an operating system is part of the operation of virtual memory. Physical pages of memory are being swapped back and forth for virtual pages of memory in a file on the hard disk. This swapping allows all programs to see the same memory structure (e.g. program loads at the same fixed virtual address in memory) and allows the machine to run as if it had more memory than it really does (but at a small speed penalty). Programs and utilities that are idle may stay loaded and ready to run, but paged out of physical memory until actually needed.
