  2. Software diagnosis - Wikipedia

    en.wikipedia.org/wiki/Software_diagnosis

    Software diagnosis—in contrast to many approaches in software engineering—does not assume that developer capabilities, development methods, programming or modeling languages are right or wrong (or better or worse compared to each other): Software diagnosis aims at giving insight into a given software system and its status regardless of the ...

  3. Troubleshooting - Wikipedia

    en.wikipedia.org/wiki/Troubleshooting

    Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.

  4. Software engineering - Wikipedia

    en.wikipedia.org/wiki/Software_engineering

    Software engineering is a field within computer science focused on designing, developing, testing, and maintaining of software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.

  5. Formal methods - Wikipedia

    en.wikipedia.org/wiki/Formal_methods

    In software development, formal methods are mathematical approaches to solving software (and hardware) problems at the requirements, specification, and design levels. Formal methods are most likely to be applied to safety-critical or security-critical software and systems, such as avionics software.

    The Deep Space Network implemented by NASA is one such system that must cope with these problems. Largely latency driven, the GAO has criticized the current architecture. [3] Several different methods have been proposed to handle the intermittent connectivity and long delays between packets, such as delay-tolerant networking. [4]

  7. Packet Tracer - Wikipedia

    en.wikipedia.org/wiki/Packet_Tracer

    Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.

  8. Network planning and design - Wikipedia

    en.wikipedia.org/wiki/Network_planning_and_design

    Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. [1] The process can be tailored according to each new network or service. [2]

  9. Software maintenance - Wikipedia

    en.wikipedia.org/wiki/Software_maintenance

    In the early 1970s, companies began to separate out software maintenance with its own team of engineers to free up software development teams from support tasks. [1] In 1972, R. G. Canning published "The Maintenance 'Iceberg '", in which he contended that software maintenance was an extension of software development with an additional input: the existing system. [1]
