Random-Access Memory (RAM), Cache, Hard Disk, Read-Only Memory (ROM)
(i) The main disadvantages of primary memory are that it has a relatively smaller storage capacity and is volatile which means data stored in the primary memory is temporary and is lost when the computer or laptop is shut down and is no longer powered. Primary memory devices are also relatively more costly to purchase and install in the computer.
(ii) The main disadvantages of secondary memory are that it is located further away from the Central Processing Unit (CPU) and therefore, the speed at which data stored in secondary memory can be accessed is slower.
Combining the two types of memory into one single memory device is not likely to be feasible as the two memory devices (primary and secondary) are designed to form a memory hierarchy in the

Thus, the hierarchical system of accessing data in the primary and secondary memory devices at different speeds will not work. This may result in an overall reduction in the speed at which data in the memory device is accessed by the
CPU, thus decreasing the performance of the CPU.
A single memory device may also result in overheating and a higher energy consumption. Also, a single memory device that incorporates the features of both the primary and secondary memory devices may be costly to manufacture and thus, may not be affordable for all users.

Cloud computing is defined as the use of computing resources - hardware and software that are delivered as a service over a network, typically the
($372 + $135 + 500) / ($2.21 - ($0.83 + .40)) = 1,028 [+/- 31]
Copious amounts of RAM accommodates many applications to run concurrently, or allocation for use as a high speed RAM disk. While smaller computing environments can function with 8GB or less, servers benefit from otherwise excessive volumes. The Xeon line supports ECC RAM to ensure integrity of data and quality of service to clients large and small.
Level 3 or L3 cache is dedicated memory that works hand-in-hand with L1 and L2 cache to increase computer performance. L1, L2 and L3 cache are computer processing unit CPU caches, verses other kinds of caches in the system such as hard disk cache. CPU cache accommodates the needs of the microprocessor by anticipating data requirements so that processing instructions are delivered without interruption. CPU cache is quicker than random access memory (RAM), and is intended to stop bottlenecks in performance.

Random Access Memory (RAM) - the storage of data and instructions inside the primary storage is temporary. It disappears from the RAM as soon as the power to the computer is
The ability of performing logic operation and signal multiplexing in the memory layer will drastically improve the overall system performance, and will also allow better utilization of the underneath CMOS layer (Figure 1 2).

Cache memory is the fastest memory outside of the CPU, runs at 10-30 ns per access.
Most of the I/O processors have its own memory while a DMA module does not have its own memory except for register or a simple buffer area.
Adding numbers in base 3 is quite simple. First of all you identify the problem, for this occasion the problem used will be 2123 +1223 knowing that we will be adding in base three means we are restricted to only using the numbers 0,1,2. Now we are going to start by adding 2 and 2 together which makes four, but you can’t write down four so we must now subtract 3 so that it can give us a number to work with, and we are also subtracting 3 because it’s the base we are working with. Then, you must carry the 1 and write down a 1 down at the bottom too. Secondly, we are going to now add the middle column, which is 1 and 2 also don't forget to add the 1 that we carried earlier.Four would be the answer but we can’t write down 4 so as previously done before we have to subtract 3 and carry a 1 and also write down 1 at the bottom of the problem because that is the answer. Finally we move to the last column which is 2 plus 1 and the other 1 we previously carried. The answer to this is four again so you just repeat the step we took earlier. Since we carried the one from the left over four we must now bring it down to our answer. At the end you should’ve ended up with the number 1,111 if

Specific purpose: to increase my audience's understanding of how memory functions and how it affects them.
It is responsible for reading the instructions and data from the main memory in order to perform calculations and coordinate the other components. It interprets instructions and processes data contained in computer programs. The actual CPU is about 1.5 inches square. Today, some of the more widely used CPU’s are made by Intel and known as Pentium 1 through Pentium 4.
