Infosys Interview Questions and Answers on Computer Networks and Software Testing
A session is a logical connection established between the source and the destination. A socket is the physical apparatus (an IP address and Port Number) used to implement a session.
UDP is a protocol without connection. TCP is connection-oriented. UDP is much simpler, faster and more efficient than TCP.
An SDLC presents the life cycle of software in the diagrammatic form. It displays the softwares methods for its complete development, maintenance, requirement analysis, etc.Â
A network is a collection of gadgets linked together via a physical transmission.Â
Node is another word for a device that is connected to a network. If two PCs, two machines, and a web server are all linked to a network, we may say there are five nodes within the network.
The following are the three different types of software testing:Â
Black-box Testing is a testing approach that only relies on specifications and requirements. This approach does not call for any understanding of the internal structures, routes, or implementations of the software being examined.Â
White box testing is a testing method that examines the internal code, execution, and integration routes of the software under test. White box testing typically calls for in-depth programming abilities.Â
When using the gray box testing technique to debug software, the tester has little access to the programs internal workings.
Confirmation: It is a statically analytical method. Without running the code, Testing is done in this case. Reviews, inspections, and walkthroughs are a few examples.Â
Testing is performed by running the code in a dynamic analysis process called validation. Techniques used in Testing that are functional and non-functional are examples.Â
The developmental and QA processes are carried out simultaneously under the V model. Testing does not have a separate phase of its own; instead, it begins with the requirement phase. The actions of validation and verification are complementary.
Networks come in four main categories.Â
PAN- The smallest and most basic network form, a personal area network, is frequently used at home. It is a link between a computer and a different gadget, such as a telephone, printer, broadband, iPad, etc.Â
LAN- Local Area Network links a few computers together in office spaces and Coffee shops. They are typically used to play games or transfer files via a network.
MAN- A more robust network type than LAN is the metropolitan area network (MAN). The MAN service area includes a small city, town, etc. A massive server is utilized to cover such a vast area for connection.
WAN- Wide Area Network is more intricate than LAN(Local Area Network) and generally spans a considerable physical distance. The largest WAN that is globally distributed is the Internet. It has a distributed ownership rather than single ownership by an organization.
