Question No. 2

Coronavirus disease (COVID-19) pandemic is a big public health challenge, it spreads globally and kills many human lives. Currently there is no vaccine available that protects against this novel virus. Now there is a need, world different communities unite to work together to defeat COVID-19 in the shape of the virtual organization like multiple hospitals and research centers may collaborate in a VO (virtual organization) to find a cure for COVID-19. In this scenario which type of computing will work to collaborate above mentioned virtual organizations globally? Support your answer with solid justification.

Question No. 3

Suppose a Toyota Indus has a computer network in its offices located in different cities all over Pakistan. Each office has a computer network of several devices and connected with every other office. Every office has different floors in the building. You are required to answer the following in the context of the above scenario.

1. On a computer network which device will change the form of data?
2. Which networking device will be used when the user wants to communicate with his/her colleague that is working in a different city’s office?
3. Which specific address will be used when the user wants to communicate through a computer network with the remote user that sits in another city’s office?
4. Which intelligent networking device will be used to connect all computers on the office’s floor?

Best of Luck!
