A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion chamber of the engine. It gives each intake cycle of the engine more oxygen, allowing it burn more fuel and do more work, thus increasing power. The power for the supercharger can be provided mechanically by … Read more
A turbine is a rotatory mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator. There are two types of turbine Impulse and reaction turbine. A reaction turbine is a turbine with … Read more
Orthogonal cutting also referred to as 2D cutting is a type of metal cutting in which the cutting tool approaches the workpiece with its cutting edge parallel to the uncut surface and at right angles to the direction of cutting. Thus, tool approach angle and cutting edge inclination are zero. In orthogonal cutting, only two … Read more
According to Bohr’s atomic model, an orbit is a fixed circular path along which electrons revolve around the nucleus of the atom. Thus, all atoms particularly revolve in an orbit. According to Bohr model, the first shell holds 2 electrons. However, Bohr’s atomic model has been rejected. The generally accepted model is the one that … Read more
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or many more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. These boilers include … Read more

An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. Internal Combustion Engines can be classified into: Internal combustion engines can further be described as 2-stroke or 4-stroke in nature. They are called “2-stroke” and “4-stroke” based on the number of … Read more
What Is Internal And External Fragmentation? Internal fragmentation is when a process is allocated more memory than required, and therefore, few space is left unused. For example: When process 1 with the size of 10KB is allocated a block of 12KB, 2KB space is left unused. Now, when process 2, with size 10 KB is … Read more
Go-Back-N Protocol And Selective Repeat Protocol Go-Back-N protocol also referred to as Go-Back-N Automatic Repeat reQuest, is a data link layer protocol that uses a sliding window method for reliable and sequential delivery of data frames. It is a case of sliding window protocol having to send window size of N and receiving window size … Read more
Paging And Segmentation Paging in operating systems, is a memory management scheme whereby a computer stores and retrieves data from secondary storage for use in main memory. In this scheme, operating system retrieves data from secondary storage in same-size blocks referred to as pages. The main idea behind the paging is to divide each process … Read more
