An alien from planet Tao has descended onto Earth. The Internet is a massive network of networks, a networking infrastructure. It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the Internet.
Explanation:
- A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network.
- Network packets are small amounts of data passed over TCP/IP networks.
- Latency measures the time it takes between your actions and the response between your computer, the internet, and everything in between.
- An IP address is a label which is used to identify one or more devices on a computer network. It is comparable to a postal address.
- The Domain Name System (DNS) is vital to the Internet, providing a mechanism for resolving host names into Internet Protocol addresses. Insecure underlying protocols and lack of authentication and integrity checking of the information within the DNS threaten the proper functionality of the DNS.
- Transmission Control Protocol is a standard that defines how to establish and maintain a network conversation through which application programs can exchange data. TCP works with the Internet Protocol which defines how computers send packets of data to each other.
Is this a true or fales question
Answer:
The correct answer is C) With respect to PERT and CPM, slack is the amount of time a task may be delayed without changing the overall project completion time.
Explanation:
The CPM (Critical Path Method) method is frequently used in the development and control of projects whose tasks have a fixed duration while the PERT (Program Evaluation and Review Techniques) method is a set of techniques with the same purpose but that allows to work with tasks with estimated probability duration but not deterministic.
Both methods are based on developing a complete scheme that includes all the tasks of a project linked to each other according to their sequence, determining the duration and analyzing different ways of reconfiguring the task planning to optimize the use of the resources of according to the general objectives of the project.
There are tasks that to start performing them must have been completed one or more previous tasks. The overall duration of the project is determined by the Critical Path, which is the sequence of tasks of greater duration. The tasks belonging to the critical path have to be carried out with special care because delays in them would cause delays in the total achievement of the project. That is why these tasks have no slack.
The rest of the tasks have some slack, which is determined by the time that a previous task can be delayed without delaying the total time of completion of the project, that is, not exceeding the duration determined by the critical path.
That is that why we say that the <em>slack</em><em> is the amount of time a task may be delayed without changing the overall project completion time</em>.
