What Is Semaphore? Semaphore is a variable or abstract data type used to control access to a common resource by multiple processes in a concurrent system such as multitasking operating system. Semaphore concept was invented by Dutch computer scientist, Edsger Dijkstra in 1962. Semaphore is typically a variable used to solve critical section problems and … Read more
What Is Battery Ignition System? Battery Ignition system is used in automobiles to produce spark in the spark plug for the combustion of the fuel in the engine. This battery is rechargeable and drives energy for its recharging from an alternator. This alternator is connected from the crankshaft of the engine and converts its mechanical … Read more
What Is Lamina Flow? In fluid dynamics, laminar flow also referred to as streamline fluid flow, is a type of fluid flow in which the fluid travels smoothly or in regular paths. In laminar flow, the velocity, pressure and other flow properties at each point in the fluid remain constant. The motion of particles of … Read more
What Is BOOTP? BOOTP stands for Bootstrap Protocol. BOOTP was originally defined as specification RFC 951 and was configured to replace the Reverse Address Resolution Protocol (RARP), also referred to as RFC 903. BOOTP can be defined as a networking protocol used by a client for obtaining an IP address from a server. When … Read more
Scalar and vector quantities used to be a thorough subject of debate among physicists for many years. It took a lot of studies and papers for a clear difference between the two quantities to emerge. These days it is quite easy to make a distinction between a scalar and a vector quantity. Scalar Quantity … Read more
A clutch is a mechanical device which engages and disengages power transmission especially from driving shaft to driven shaft. The clutch connects the two shafts so that they may be locked together and spin at the same speed (engaged), locked together but spinning at different speeds (slipping) or unlocked and spinning at different speeds (disengaged). … Read more
Polymerization describes the formation of large molecules (Polymers) with repeating structure from small molecules (monomers). There are two types of polymerization reactions, additional and condensation. Additional Polymerization Additional polymerization is a polymerization in which the growth of polymer chains proceeds by addition reactions between molecules of any size. It involves the linking of monomers with … Read more
Client-Server Network A client server network is a specific type of online network comprised of a single central computer acting as a server that directs multiple other computers, which are referred to as the clients. By accessing the server, clients are then able to reach shared files and information saved on the serving computer. Examples … Read more
Uniform Memory Access (UMA) Uniform memory access (UMA) is a shared memory architecture used in parallel computers. All the processors in the UMA model share the physical memory uniformly. In UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data. There … Read more
Twisted pair cable, fiber optic cable and coaxial cable are three major types of network cables used in modern communication systems. These cables mainly differ from one another in terms of latency, speed of data transfer and overall security. What Is Twisted Pair Cable? Twisted pair cable is a type of cable in which two … Read more
