A typical computer has 3 types of memory: Cache memory, Random Access Memory (RAM), and virtual memory. Cache is the fastest and most expensive, RAM is slower and less expensive, and virtual memory is the slowest and least expensive type.
What is the fastest type of memory in a computer?
- Fastest memory is cache memory.
- Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.
Which memory is the most expensive?
Cache memory is the fastest and most expensive type of memory in most devices.
What computer is the fastest most powerful and most expensive type of computer?
1. Supercomputer – The fastest, largest, most powerful and most expensive computer.
Is it faster for the CPU to retrieve data from a hard drive or from RAM?
Accessing data from the hard drive to send to the CPU is faster than accessing data from RAM. The heads of a hard disk drive touch the surface of the platter to read or write the data. RAM prices tend to be very stable.

What are the 3 types of memory?
The three main forms of memory storage are sensory memory, short-term memory, and long-term memory. Sensory memory is not consciously controlled; it allows individuals to retain impressions of sensory information after the original stimulus has ceased.
Which memory has shortest access?

Which is lowest in memory hierarchy?
Most modern computer systems use a hard drive made of magnetic or solid state storage as the lowest level in the memory hierarchy (see Figure 8.4). Compared with the ideal large, fast, cheap memory, a hard drive is large and cheap but terribly slow.
What are four types of memory in a computer?
Memory consists of four types of memory chips RAM, ROM, CMOS and flash. RAM stand for random access memory and ROM stand for read only memory. these are also called primary memory of a computer.

What hardware makes a computer run faster?
Having a processor with more cores and a higher clock speed means that you can interact with more applications, more quickly. Good ratings in these fields are what makes your computer faster. For the most rigorous routines, whether it’s gaming or video editing, 4.0 GHz is a good baseline for processor speed.
What makes a computer faster RAM or processor?
Generally, the faster the RAM, the faster the processing speed. With faster RAM, you increase the speed at which memory transfers information to other components. Meaning, your fast processor now has an equally fast way of talking to the other components, making your computer much more efficient.
What makes a computer faster RAM or SSD?
SSDs are much faster than hard drives since they use integrated circuits. … Even though SSDs use memory chips instead of a mechanical platter that has to be read sequentially, they’re still slower than the computer’s RAM.
