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...]
Difference Between Stop-and-Wait Protocol and Sliding Window Protocol
Stop-and-wait protocol and Sliding window protocol are the methods evolved for handling the flow control of the network data transfers. These methods mainly differentiated by the techniques they follow such as stop-and-wait uses the concept of the acknowledging each data unit before sending another data unit. Conversely, sliding window protocol allows the transition of the several data units before sending an acknowledgement. Among the two protocols, the sliding window protocol is more … [Read more...]
Difference Between HDLC and PPP
The major difference between HDLC and PPP is that HDLC is the bit oriented protocol, while PPP is the character-oriented protocol. The HDLC and PPP are the crucial data link layer protocols used in WAN (wide area network) where the HDLC can also be implemented with PPP for the efficient results. HDLC describes the encapsulation technique employed on the data in the synchronous serial data link. On the other hand, the PPP protocol deals with the encapsulation of the data transported in the … [Read more...]
Difference Between SIP and VoIP
The SIP and VoIP are the technologies work for enabling any type of communication over the internet. However, the VoIP is separately used for IP telephony, but SIP is the protocol which handles the overall exchange of multimedia. More specifically, the SIP signalling protocol is the way to standardise the VoIP or IP telephony. The SIP (Session Initiation Protocol) is used to set up the internet telephone calls, video conferencing and other multimedia connections. On the other hand, the Voice … [Read more...]
