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
In computer graphics, the art of transforming three-dimensional objects into a two-dimensional representation is essential. This process, known as projection, allows us to portray complex 3D scenes on a flat screen, enabling us to comprehend and interact with the digital environment effectively. Two popular projection methods, parallel and perspective projection, serve as the backbone of … Read more
Now, what is a diesel engine and a petrol engine? Petrol and diesel engines are the main engines in the automobile industry today and both are internal combustion engines. The diesel engine is an internal combustion engine in which air is compressed to sufficiently high temperature to ignite diesel fuel injected into the cylinder, where … Read more
