The memory system hierarchy refers to the different levels of memory in a computer system, ranging from the smallest and fastest memory to the largest and slowest memory. As we move down the hierarchy, we generally see an increase in storage capacity and a decrease in speed. However, the exact relationship between size and speed depends on the specific technologies used in each level of the hierarchy. At the top of the hierarchy is the CPU cache, which is the smallest and fastest type of memory. The cache is used to store frequently used data and instructions that the CPU can access quickly. The size of the cache is typically measured in kilobytes or megabytes, and it is designed to provide very fast access times, usually measured in nanoseconds. Moving down the hierarchy, we find main memory or RAM (Random Access Memory), which is larger than the cache and slower. RAM is used to store data and instructions that the CPU needs to access frequently but not as frequently as cache data. RAM is typically measured in gigabytes, and access times are typically measured in nanoseconds. Below RAM, we find secondary storage, which includes hard drives, solid-state drives (SSDs), and other types of non-volatile storage. These storage devices are larger than RAM but much slower. They are typically measured in terabytes, and access times are measured in milliseconds. Finally, we have tertiary storage, which includes magnetic tape, optical storage, and other types of very large but very slow storage devices. These devices are typically used for backup and archival purposes, and they have access times measured in seconds or even minutes. In general, as we move down the hierarchy, we see an increase in storage capacity and a decrease in speed. However, the rate of increase in size and decrease in speed varies depending on the specific technologies used in each level of the hierarchy.
There is no limit to the number of times electricity could be measured.
it is measured by using length times width times height
a mudslide is measured by the feet and times it by every 2 feet
Memory access times are measured in nanoseconds. But that is only part of the story. What exactly is the item you wish to access? Are you planning to access more that one item? Do you have control over how and where the items are stored? Are they in the cache when you want to access them. What are the details of the design of the memory you are accessing? For special problems data access can be sped up by using custom designs. What is you budget? Do you have access to a lab? Does this help?
access times from memory is 200,000 times faster than access times from storage devices due to the mechanical movement involved.
An SSD drive works by using a series of flash memory chips to rapidly reduce access times and increase transfer speeds. In contrast to traditional platter hard drives, there are no moving parts to fail.
The amount of memory in your computer does not directly limit the size of your hard drives, but it may slow access times.
in earlier times time was measured by sandclock or waterclock
