Final answer:
Question 1:
- When requesting to view a You Tube video on your mobile phone at home, the video needs to travel through several data communication equipment (DCEs) before you can view it.
- If you are viewing the same video on your portable laptop on the 5th floor of the school building, the journey of the video through DCEs would be slightly different.
- There is no physical connection between the Data Center in Bangladesh and the school building. The connection between these two locations is established through a series of interconnected networks that form the internet.
Question 2:
- 1. No, multiple devices cannot have the same IP address at the same time within a home network. Each device connected to a network must have a unique IP address to ensure proper communication and routing of data. IP addresses serve as unique identifiers for devices within a network.
- 2. No, you and your neighbor cannot have devices with matching IP addresses at the same time, even if you are not sharing the same network. IP addresses are globally unique and are assigned to specific devices or networks.
Step-by-step explanation:
Question 1:
1. First, your phone needs to establish a connection with your home Wi-Fi router. The DCE in this case would be the Wi-Fi router itself. Once connected to the router, the video request is sent over the internet to your internet service provider (ISP). The DCE here is the network infrastructure of your ISP, which may include routers, switches, and other networking equipment.
From your ISP, the video request is routed through various DCEs, such as routers and switches, across the internet backbone. These DCEs are part of the internet infrastructure and are responsible for directing the video request towards the destination.
Eventually, the video request reaches the data center in Bangladesh where the video is stored. The DCEs in the data center, including servers, switches, and routers, handle the request and retrieve the video from storage.
Finally, the video is sent back through the internet, passing through the same DCEs in reverse order, until it reaches your phone. Your phone's DCE, the Wi-Fi router, receives the video data and displays it on your screen, allowing you to view the video.
2. Similar to the mobile phone scenario, your laptop needs to connect to the school's Wi-Fi network. The DCE here is the Wi-Fi router in the school building. Once connected, the video request is sent over the school's network infrastructure, which includes routers and switches, to the ISP responsible for the school's internet connection.
From the ISP, the video request follows the same path as in the previous scenario, traveling through various DCEs across the internet backbone until it reaches the data center in Bangladesh. The DCEs in the data center process the request and retrieve the video.
3. Data travels over the internet using a combination of physical connections (such as fiber optic cables) and virtual connections (such as routers and switches). These connections enable data to be transmitted between different locations worldwide.
In the case of viewing a video from the Data Center in Bangladesh on your laptop at the school building, the data travels through a series of routers, switches, and other networking equipment across the internet. These devices receive and forward data packets along the most efficient path towards the destination
Question 2:
1. Imagine your home network as a neighborhood with houses. Each house has its own address, which allows mail and packages to be delivered to the correct house. Similarly, each device on a network, such as a computer, smartphone, or smart TV, needs a unique IP address to receive data sent to it.
When you connect a device to your home network, it is assigned an IP address by the router. The router acts as a central hub, directing data to the appropriate device based on its IP address. If two devices were to have the same IP address, the router would not be able to distinguish between them, leading to communication issues and data routing problems.
2. Think of IP addresses as phone numbers. Just like no two people can have the same phone number, no two devices can have the same IP address. IP addresses are managed by organizations such as Internet Assigned Numbers Authority (IANA) and are carefully allocated to ensure uniqueness across the internet.
When you and your neighbor connect your devices to your respective home networks, your routers assign IP addresses from a pool of available addresses. These addresses are unique within each network, but they may be similar to IP addresses assigned by other routers in different networks.
