Is cache memory a removable memory?
No, a cache memory is often used to store data that has been needed recently on grounds that it will be faster to access when/if it is needed again. When data that is requested is contained in the cache you have a cache hit, and when you have to retrieve it from the hard drive (or where ever its original storage was) again it is called a cache miss. Retrieving data from the hard drive is slower than retrieving it from the cache.
What is temporary storage on chips called?
Temporary storage on chips is called memory. Most such solid-state memory is in the form of random-access memory (RAM) chips, usually dynamic RAM (DRAM). The people who write operating systems and the computer architects that design computer systems and CPUs often use many different temporary storage areas, each one with a different name. If you are building a high-speed computer or writing a high-performance operating system, you will learn about the temporary storage areas known as the disk page cache, the stack, the heap, and the virtual memory page table, are (more or less) stored in the main memory DRAM. The CPU has a few temporary locations called registers. Often there is one or more levels of cache (the L1 cache, the L2 cache, etc.) between the CPU and the main memory. High-performance CPUs typically put a cache on the same chip as the CPU; some older personal computers had an "external cache" SRAM chips between the CPU chip and the main memory DRAM chips. Many high-performance computers have several levels of successively larger and slower caches -- an extremely fast I-cache and D-cache and TLB, the L1 cache, the L2 cache, the L3 cache, and main memory.
What is the CPU often referred to as?
CPU is the "commonly known as" name of that component. Either CPU or Processor. The acronym CPU stands for "Central Processing Unit". The previous answer of "mother bored" is completely wrong for 2 reasons: 1) it is "motherboard" or "mother board" 2) the CPU is a required add-on component TO the motherboard, not the motherboard itself.
What additional hardware will be necessary to implement two identical hard drive?
Hardware will be RAID PCIe / PCIx RAID hardware controller but The hardware RAID is often the motherboard RAID controller or a separate RAID card.
Which internal PC component generally uses the most power?
More often than not, also depending on the type of PC lover you are, you will find that it is mostly the Graphics card that will use most power. Unless you have a built in grahpics card, then it will most likely be the motherboard.
What is the definition for the word cache?
A cache is a small hidden store of something, often food or fuel. "I left my spare clothes in a cache in a recess in the cliff wall."
What is level 1 2 and 3 cache?
; L3 Cache (Level 3 Cache) This type of cache is becoming more prevalent as microprocessor manufacturers ship more processors with L1 and L2 cache built into the processor. L3 cache is then the extra cache that sits on the motherboard between the processor and main memory, since the processor already contains L1 and L2 cache. Some processors are starting to ship with L3 cache built-in as well to speed up memory operations further. In those cases the L3 cache often sits on a separate area of the die, not built directly into the chip core.
Which type of CPU cache has the highest latency?
The Level 3 (L3) cache has the highest latency. The CPU cache is memory that is used to decrease the time that it takes the CPU to access data. Because the data is cached, it can be accessed more quickly. The CPU cache is often found directly on the CPU or built into the CPU. The L3 cache is usually larger than the L1 and L2 cache, but it is searched last. The CPU searches for data in the following order: L1 cache, L2 cache, L3 cache, RAM.
Is cache memory a removable memory?
No, a cache memory is often used to store data that has been needed recently on grounds that it will be faster to access when/if it is needed again. When data that is requested is contained in the cache you have a cache hit, and when you have to retrieve it from the hard drive (or where ever its original storage was) again it is called a cache miss. Retrieving data from the hard drive is slower than retrieving it from the cache.
What is the difference between cache vs cold cache vs hot cache vs warm cache vs cache hit vs cache miss?
Firstly, it sounds like you are asking for general definitions, rather than differential definitions, which is problematic when the definitions are differential and context specific. Cache miss: not in cache, must be loaded from the original source Cache hit: was loaded from cache (no implication of what "type" of cache was hit). cold cache: The slowest cache hit possible. The actual loading mechanism depends on the type of cache (CPU cache could refer to an L2 (or L3) hit, disk cache could refer to a RAM hit on the drive, web cache could refer to a drive cache hit) hot cache: The fastest cache hit possible. Depends on mechanism described (CPU could be L1 cache, disk could be OS cache hit, web cache could be RAM hit in cache device) Warm cache: Anything between, like L2 when L1 is hot and L3 is cold. It is a less precise term and often used to imply "hot" when the performance is closer to "cold."
Which motherboard is besty for a Dell Inspirion?
It is often hard to fit an after market motherboard into dell computers, you would have to check the dell website.
What is the main memory located in a mini computer?
"Main" is not a precise term. The memory that is closest to the processor (often integrated on the same chip is the cache memory (there are often different levels of cache), just beyond the processor but still on the motherboard is the significantly larger Random Access Memory (RAM) which is solid state but needs power continuously to refresh itself - this memory is emptied when the computer is powered down. Beyond the motherboard is the memory that is not volatile (does not reset on powering down) it used to be "hard disk drives" (HDD), spinning disks covered with magnetic particles; now you can purchase Solid State Drives (SDD) which have no moving parts at all and that interface with the computer in exactly the same way with the same cables and all as the HDD did.
What does a MotherBoard do exactly?
The Motherboard functions as the main circuit board that connects and communicates to all the devices and components attached in the computer. The motherboard facilitates the communication of devices with each other.
Reasons of why the westerns attacked?
They were usually violent and often historically unsound.
Why do need cache memory?
Cache simply is for speeding up the processes already completed, since it is faster than ram, and easier to access. it basically is just for speeding up applications you use often. cache is volatile meaning that it is erased when you turn off your computer.
What is processor cache memory?
Processor cache is intermediate memory between the processor itself and main memory (RAM). Because processors can read data so much faster than main memory, the speed of a processor would essentially be limited to the speed of RAM if we couldn't find a way to increase the efficiency of accessing data in main memory. Caches, which have a much lower access time than RAM, help to mitigate this problem. Caches work on the principle of spacial locality. That is to say, they use the idea that if you access a location in main memory, then it is highly likely that the next memory location you want to access is very close to where you are. When you access main memory, the cache will actually pull in a "chunk" of data (often called a "cache line") in the hope that the next time you try to access data it will already be in the cache. Typically there are two levels of cache (though with the increasing popularity of multi-core processors, three levels of cache are becoming more and more necessary). The first level of cache (L1 cache) is what is directly accessed by the processor and is therefore the fastest (and most expensive) cache. L1 cache is usually split into two parts: data cache and instruction cache. The instruction cache holds the instructions of running programs that the processor needs to execute. The data cache holds the data being used by current instructions. The second level of cache (L2 cache) is where the L1 cache pulls in information from. L2 cache is slower than L1 cache, but is more affordable and can be much larger than L1. With the exception of L3 caches mentioned above, this is the cache which pulls information in from main memory.
