Sensors and Actuators are essential elements of the embedded systems. These are used in several real-life applications such as flight control system in an aircraft, process control systems in nuclear reactors, power plants that require to be operated on an automated control. Sensors and Actuators mainly differ by the purpose both provide, the sensor is used to monitor the changes in the environment by using measurands while the actuator is used when along with monitoring the control is also … [Read more...]
Difference Between Forward Engineering and Reverse Engineering
Forward engineering and Reverse engineering are part of the re-engineering process and closely related. The crucial difference between the forward engineering and reverse engineering is that forward engineering employs the change in the subject system during restructuring. Conversely, reverse engineering whole sole purpose is to examine the system to obtain its more abstract design. Software re-engineering is nothing but the re-implementation of the legacy system to achieve more … [Read more...]
Difference Between C# and C++
C# and C++ are the programming languages where the C++ is the descendant of the C#. However, C# is derived from C language and it has many features of C and C++, but some features are also dropped in the C#. When it comes to programmer's productivity the C# is miles ahead from C++ and C. The major difference between the C# and C++ lies within its applications where the C# can be used to develop web as well as business applications whereas C++ is useful when the programmer wants to create … [Read more...]
Difference Between Algorithm and Flowchart
In programming, the solution to a problem is first elucidated in the form of the algorithm which contains sequential steps for the solution. For the programmer convenience, the two forms are evolved to express the algorithm that is Flowchart and Pseudocode. A flowchart is constructed with the help of various symbols and provides more understandability to the algorithm. The algorithm and flowchart are the two sides of the same coin and dependent terms. Creating an algorithm is a very crucial … [Read more...]
Difference Between Top-down and bottom-up Integration Testing
The primary difference between the top-down and bottom-up integration testing is that the top-down integration testing utilizes the stubs for calling the submodules subordinated to the main function while in bottom-up integration testing the stubs are not needed instead drivers are used. The related redundancy is more in case of the top-down approach as compared to the bottom-up. These two techniques are the part of the integration testing which provides an organised way to build the program … [Read more...]
Difference Between Smoke and Sanity Testing
The smoke and sanity testing are techniques work as a part of the integration and regression testing respectively. The significant difference between the smoke and sanity testing is that the smoke test is employed in the unstable product while the sanity testing is applied to the more stable products. The smoke testing can be said to be shallow testing as it just tests for the vital requisite, but sanity testing examines each of the modules of the software at the end, for checking whether the … [Read more...]
Difference Between Verification and Validation
The Verification and Validation are the terms usually used in the context of the software. The verification and validation can be distinguished by the fact that software verification is a process of the checking the design outputs and comparing it with the specified software requirements. On the contrary, software validation is the process of examining the software specifications against the user needs. In a broad way, these activities complete each other and are a part of the Software … [Read more...]
Difference Between Unit Testing and System Testing
The unit testing and system testing are the interdependent activities of the software testing. Unit testing is the method of testing various isolated software components separately. But when it comes to system testing, it is the technique in which the entire system is exercised with a series of the different tests. In the software testing process, the unit testing is situated in the innermost part of the spiral, on the other hand, system testing is shown in the outermost part of the … [Read more...]
Difference Between Star and Mesh Topology
Star and mesh topology are the types of the topologies where star topology comes under the peer-to-peer transmission and mesh topology works as a primary-secondary transmission. However, these topologies mainly differ in the physical and logical arrangement of the connected devices. The star topology organises the devices around the central controller known as the hub. On the other hand, the mesh topology connects each device to another device with a point-to-point link. Content: Star Topology … [Read more...]
Difference Between Frame Relay and ATM
When the multimedia is transferred across the network, it needs the variable bandwidth and distinct traffic types which is known as the heterogeneous service. To deliver these services the high transmission rate is required, and different bit rates must be combined. These characteristics are achieved by distinct techniques known as frame relay and ATM (Asynchronous Transfer Mode). The difference between frame relay and ATM lies in the speed of transmission, efficiency, accurate delivery of the … [Read more...]
