Case Project 1-1
Networking Gadgets, Inc. requirements are secured centralized access network for 18 people that is easy to manage and back up. They need server-based network because peer-to-peer network model has no centralized authority or control over resources. On the other hand, server-based network provides centralized control over network resources and will have secure access to project files and will fulfill company’s need for centralized management and back up requirement. So, all of these factors are the key reasons for using server-based network.
Case Project 1-4
For my GPS to upload data to my PDA wirelessly, I would use a short-range networking technology which is WPAN ( wireless personal area network ). The WPAN is a short-range networking technology designed to connect personal devices to exchange information. Bluetooth technology is a very good example of WPAN short-range technology which can exchange information between my GPS and PDA.
Case Project 2-1
To upgrade this network of 50 computers connected with hubs, I would do two improvements to this network. First of all, I would use switches instead of hubs because hubs are the main reason for poor network response time caused by collisions. Hubs have many drawbacks. They share bandwidth which slows the process of transferring large files and accessing network applications, where as switches have dedicated bandwidth. The other improvement would be to use the switches with 100mbps bandwidth instead of 10mbps. This upgraded network will allow the company to expand its network as its future requirements grow.

I found this article to be very interesting. In this article author is telling us about a bug called Heartbleed Bug, which can affect our network devices such as routers, network attached storage devices and access point. These devices use open SSL for software encryption, so these devices
