Answer:
1. Supercomputers
Supercomputers are very expensive and very fast. They are the most powerful computers we have in the world.
Supercomputers are optimized to execute only a small number of programs. This makes it possible for them to execute these few programs at a very high speed. Due to their inhibiting cost, they are used in high-end places like in scientific research centers. The supercomputer consists of thousands of processors, allowing it to clock in at very high speeds measured by petaflops.
These computer types are also very large in size due to the numerous parts and components involved in their design.
A good example of a supercomputer is Tianhe-2, which is located in the National Supercomputer Center in Guangzhou, China. It features 3.12 million cores, allowing it to run at speeds of 33.86 petaflops.
2. Mainframe Computers
These are large and expensive computers that are capable of supporting thousands of users simultaneously. They are mostly used by governments and large organizations for bulk data processing, critical applications, and transaction processing. They are ranked below supercomputers.
3. Minicomputers
Minicomputers are mid-sized computers. In terms of size and power, they are ranked below mainframes. A minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.
The use of the term minicomputer has diminished since the introduction of microprocessors. These machines are now more commonly called midrange computers.
4. Microcomputers
A microcomputer, also known as a personal computer, is designed to be used by one user at a time. The term microcomputer relates to the microprocessor that is used for the purpose of processing data and instruction codes. These are the most common computer types since they are not very expensive
Inside the case are the components that make up the computer itself, such as the RAM memories, the processor and the hard disk, all of which are directly or indirectly connected to the motherboard. In addition, the case allocates the power suplly, which is responsible for supplying power to the computer.
<h3>What is a computer case?</h3>
The case is the hardware component used to house most parts of a computer. It is inside it that components such as CPU, motherboard, SSD, video card and power supply are placed.
In addition, it is where the outputs for connections to other equipment are found, such as USB and HDMI outputs, plug for sound box and microphone and input for memory card.
The case has the important function of protecting the internal components of a computer from knocks, heat, light, moisture and dust. That's because most of the electronic components inside a computer are very sensitive and need this protection.
It is also used to connect to other hardware components, such as a monitor, keyboard, mouse and headset, through the various outputs provided on its exterior.
