Friends can challenge us, confuse us, and sometimes, we might wonder why we bother. But friendship is as important to our wellbeing as eating right and exercising. What’s more, friendships help us grow through each year of our lives.
The friends we meet in school teach us how to be patient, wait our turn, reach out, and try new hobbies. When we move into young adulthood we learn more about taking responsibility, finding a career path, and seeking out people as mentors.
As we continue into our 40s and beyond, we learn to weather the ups and downs in life, and once again friends provide a sounding board and place for us to grow. Friendship is key to our success with all our relationships and it can create a sense of purpose in our lives.
The people we bring into our lives as friends will show us how to forgive, laugh, and make conversation. The basic components of any relationship, from our marriage to our coworkers, are all founded in friendship. We learn how to interact with people because of our friends, even the ones that are opposite from us or share a different worldview.
We don’t just talk with others but learn from them. We understand the process of meeting new acquaintances and finding out what makes them tick. These people help push us out of our comfort zones while still providing a safe emotional space for us to be totally ourselves.
One of the most overlooked benefits of friendship is that it helps keep our minds and bodies strong. In fact, it’s as important to our physical health as eating well and keeping fit. A recent Harvard study concluded that having solid friendships in our life even helps promote brain health.
Answer:
1. PANs uses Star Topology.
2. LAN uses four topology (Bus, Ring, Star and Tree).
3. MAN uses Star Topology.
4. WAN uses Bus topology.
Explanation:
1. PAN is the personnel area network, in which different personnel devices of a person are connect to each other with the help of the central computer with the help of Bluetooth, WiFi or some other medium. The central computer will work like a hub and all the devices are directly connected to the central PC. It is same as the ring topology where all the devices are connected to the central PC. So we can say that, PANs use star topology.
2. LAN is the local area network that has been established with in the premises of the organization. In this type of network, four typologies involve to complete the network connection. First is star topology, that is used to connect all the devices with the switches. Then Bus topology is used to connect all the switches with the single main cable. Ring topology is involved to connect all the switches with each other. Tree topology is used to connect different block if the organization in the form of branch to connect the central router or switch.
3. MAN is the Metropolitan Area Network which is comprise of different LANs. All the LANs are connected to the Router in the form of Star topology.
4. WAN is the wide area network. In WAN different MANs are connected to the network through single cable. This type of network uses Bus topology.
