Multiprocessors can be divided into three shared-memory model categories- UMA (Uniform Memory Access), NUMA (Non-uniform Memory Access) and COMA (Cache-only Memory Access). The models are differentiated based on how the memory and hardware resources are distributed. In the UMA model, the physical memory is evenly shared among the processors which also have equal latency for every memory word while NUMA provides variable accessing time for the processors to access the memory. The bandwidth … [Read more...]
Difference Between PLA and PAL
PLA and PAL are types of Programmable Logic Devices (PLD) which are used to design combination logic together with sequential logic. The significant difference between the PLA and PAL is that the PLA consists of the programmable array of AND and OR gates while PAL has the programmable array of AND but a fixed array of OR gate. PLD's provides a more simple and flexible way of designing the logic circuits where the number of functions can also be increased. These are also implemented in … [Read more...]
Difference Between Microprocessor and Microcontroller
Microprocessor and Microcontroller are the typical programmable electronic chips used for distinct purposes. The significant difference between them is that a microprocessor is a programmable computation engine consist of ALU, CU and registers, commonly used as a processing unit (such as CPU in computers) which can perform computations and make decisions. On the other hand, a microcontroller is a specialised microprocessor considered as "computer on a chip" as it integrates components like … [Read more...]
Difference Between Sensors and Actuators
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...]
