Hubs are very simple devices that connect network components, sending a packet of data to all other connected devices.
Hubs are relatively basic network connectors that send a packet of data to every other connected device. Compared to a hub, a switch is more intelligent and has the ability to filter and forward data to a specific location. Within various networks, switches are utilized. Nodes of the network are any computers or printers connected to it. A network workstation is a personal computer that is linked to a network (note that this is different form the usage of the term workstation as a high-end microcomputer). Nodes of the network are any computers or printers connected to it. A network workstation is a personal computer that is linked to a network.

Answer:
B. GRID COMPUTING , ON - DEMAND COMPUTING AND REAL TIME COMPUTING
Explanation:
Grid computing, on-demand computing and real time computing are currently the most impactful information technology processes. The Grid computing from example entails distributed computing whereby computing resources are distributed across different systems for a computing task. This is seen in server systems where a super virtual computer composed of a network of computers are connected to share resources and perform large tasks. This form of computing has majorly affected and improved complex computing tasks today.
On demand and real time computing are also other notable trends in IT with real time computing bringing the power of live and direct coverage of information to our screens and on demand making it possible for the average user to access computing resources as needed such as in the services of cloud computing providers
Answer:
a. 0.01
b. 0.001
c. The identification field of the packet fragment can be used to uniquely identify and collate the fragments lost in transmission.
Explanation:
The probability of losing a packet is 10% or 0.1, so the probability of losing the packet twice during transmission;
= 0.1 x 0.1 = 0.01
When any fragments have been part of the transmission, the probability of the packet is dependent on the fragments;
= 0.01 x 0.1 = 0.001
The identification field is a unique 16-bit value assigned to an IPv4 packet, when a packet is fragmented for transmission, its field is used to collate the unique fragments in the packet.
Answer:
D. integrated development environment
Explanation:
Given that an integrated development environment is a form of computer software App that allows the users or programmers to develop a software App in a way the enables them to carry out different operations including source code development, build and test automation, and debugging activities.
For example NetBeans, Eclipse, IntelliJ, and Visual Studio.
Hence, in this case, the correct answer is "integrated development environment."
