<u>Solution and Explanation:</u>
Unified Extensible Firmware Interface (UEFI) is a software program which connects the computer's firmware to its operating system (OS). UEFI is installed by the manufacturer and the first program to be executed when the computer is not turning on. UEFI or BIOS can be corrupted because of the upgrade error or any other damage.
Launch an automatic BIOS/UEFI recovery of the system so that the previous working best version of UEFI/BIOS is recovered and made available. On successful recovery of the BIOS/UEFI, the computer starts working.
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
When permanent magnets of a motor are replaced with more powerful ones, the motor rotation will increase. This is because there is more electricity being generated.
