Answer:
Topology means arrangement of nodes
Explanation:
In computer science the word topology means the arrangement of nodes and elements in a network. For any topology we do need nodes and cables for maintaining the infrastructure.
In mesh topology the all nodes use to get connected by direct link. While each and every node is directly associated with one another. In this infrastructure we do need lot cabling where every node will be connected with one another. While usage of good quality cable in network is also expensive to manage. Although there are lot of benefits of this topology, where the transmission of data would never stop if node is not working the rest will be working to transfer the data among other nodes ,this is more secure because there is no traffic for data to travel via many nodes to reach the destination. Every node is directly connected and communicate. So, once the node is not working the communication will not be stop but the maintenance and troubleshooting will be difficult in this infrastructure.
It is proved along with lot of benefits and network security ,this infrastructure is having some disadvantages as well. Cabling expense , maintenance cost etc . usually small scale networks do not prefer mesh topology. Small scale and low budget companies can not afford this topology because it is expensive.
Although we do believe that the data security is most important for today's era ,so few companies those wanted to keep their information secure and confidential they must use mesh topology by ignoring the cost incurred for this set up. Data security and integrity would never be compromised by some of the companies.
Mesh topology is more safer, more quick infrastructure which is although very expensive , difficult to mange and maintain. Moreover it is overhead of cabling as well to connect every node but the demand of mesh topology would never be less. It is demanding and appealing topology still.
Answer:
Incremental method.
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
An incremental model refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.
Hence, an incremental method typically involves developing a system through repeated cycles and smaller portions at a time, enhancing and evolving the system over time.
In SDLC, a waterfall model can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.
Also, a spiral model can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.
Answer:
England began expanding its border with exploration in the late 16th century.
Explanation:
During the age of discovery, which is a period of exploracion protracted from 15th century to 16th century, different overseas travels were carried out in order to explore and that resulted in the appropiation of other lands. England, France, and the Netherlands began to establish colonies and trade networks of their own in the Americas and Asia.
Answer:
Check Explanation.
Explanation:
Immediately there is a connection between your laptop and the wireless hotspot, data will be transferred via the Physical layer that will be used for encoding of the network and the modulation of the network and that layer is called the OSI MODEL.
Another Important layer is the APPLICATION LAYER in which its main aim and objectives is for support that is to say it is used in software supporting.
The next layer is the PRESENTATION LAYER which is used during the process of sending the e-mail. This layer is a very important layer because it helps to back up your data and it is also been used to make connections of sessions between servers of different computers
Explanation:
ICT permeates all aspects of life, providing newer, better, and quicker ways for people to interact, network, seek help, gain access to information, and learn. Besides its presence everywhere, Information and Communication Technology has an immense economic significance.
