Scalar Quantity vs Vector Quantity Math and physics are two subject invented by us to describe various phenomenon around us. This fits perfectly upon quantities that are measured using math and physics. Scalar and vector are classification of quantities in physics. There are some quantities that have only one dimension that is a number assigned […]
Difference Between Propeller and Impeller
Propeller vs Impeller For those who have studied motion, especially that of different types of fans, there is no confusion between the terms propeller and impeller but ask those who think they have heard these two terms but haven’t studied them and you will get all sorts of answers. Part of the confusion is also […]
Difference Between Kinematics and Dynamics
Kinematics vs Dynamics Physics is the study of matter, their energy and their interaction. Physics is also the study of motion of objects. This study is also known as dynamics, a word that is derived from a Greek word dunamis that means power. Now study of motion is not possible without knowing the causes of […]
Difference Between Acceleration and Retardation
Acceleration vs Retardation The concept of acceleration is an important one when it comes to study of moving bodies. Acceleration refers to the rate in change of velocity of a moving body. If a body is moving at a constant velocity, there is no change and hence it has no acceleration. You can understand the […]
Difference Between Absolute Pressure and Gauge Pressure
Absolute Pressure vs Gauge Pressure Pressure is an important concept in physics and finds scores of industrial and daily life. It is defined as force per unit area when it is applied in a direction perpendicular to the surface of the body on which it is applied. But what we measure with devices designed to […]

Difference Between Solaris 10 and Solaris 11
Solaris 10 vs Solaris 11 Solaris is an operating system that belongs to the UNIX family of operating systems. It is now owned by Oracle who bought it from its original developers Sun Microsystems in January 2010. Consequently, it is now known as Oracle Solaris. Solaris was the first operating systems to introduce popular features […]
Difference Between Algorithm and Pseudocode
Algorithm vs Pseudocode An algorithm is simply a solution to a problem. An algorithm presents the solution to a problem as a well defined set of steps or instructions. Pseudo-code is a general way of describing an algorithm. Pseudo-code does not use the syntax of a specific programming language, therefore cannot be executed on a […]
Difference Between Embedded and External Memory Devices
Embedded vs External Memory Devices Embedded memory is a memory that is integrated in to the chip and it is a non stand alone memory. Embedded memory supports the logic core to perform its functions eliminating inter-chip communication. External memory devices refer to memory devices that reside outside of the logic core. Currently, embedded SRAM […]
