<u>Software modelling:</u>
Software modelling can be defined as the ways of expressing the design of the software.
Software modelling tools have great significance in developing and representing the design of the software.
The software modelling tools can be used to estimate the work needed to done per task by determining the work to be done on each task that constitutes the build of the software and then the individual amount of work done per task can be added for all the tasks and the total amount of work to be done is obtained as a result.
Answer:
True
Explanation:
OOP or object oriented programming is a structured programming process that relates or classify data into fields. It is based on creating objects with available data.
OOP deals with classes and objects. Classes are containers or a defined collection of objects. Objects are collections of data that identifies that object.
An example of class and object is man and John, where man is the class and John, the object.
There can only be one version of the class "man" in the program.
In OSPF configuration mode, an engineer would use the no network network-id and area area-id subcommands to remove the network commands.
Information About OSPF:
OSPF is an Interior Gateway Protocol (IGP) designed specifically for IP networks, and it supports IP subnetting as well as tagging of externally derived routing information.
OSPF also supports packet authentication and sends and receives packets using IP multicast. RFC 1253 and the OSPF management information base are supported by the Cisco implementation.
The Cisco implementation adheres to the OSPF Version 2 specifications by including the following key features:
- Definition of stub areas is supported.
- Routes learned through one IP routing protocol can be redistributed into another. This means that OSPF can import routes learned through EIGRP and RIP at the intradomain level. Routes from OSPF can also be exported to RIP.
- Plain text and MD5 authentication are supported between neighboring routers within an area.
- Interface output cost, retransmission interval, interface transmit delay, router priority, router dead and hello intervals, and authentication key are all configurable routing interface parameters.
- Virtual links are supported.
- Not-so-stubby-areas (NSSAs) per RFC 1587are supported.
