The chief ethical concern is "Privacy".
A negative aspect of an enormous number of sources available on internet is the concerns about privacy. Web privacy includes the privilege or command of individual protection concerning the sorting, re-purposing, arrangement to outsiders, and showing of data relating to someone through the Internet.Internet security is a subset of data privacy. Privacy concerns have been enunciated from the beginnings of substantial scale PC sharing.
Answer:
RFID scanning or Barcode reader
Explanation
Smart refrigerators have inbuilt RFID scanning technology that help monitor the stock that is inside your fridge. Once you pass your items through the inbuilt RFID scanner in the fridge, the barcode of your items is cross-referenced with a database and given a unique tag for identification. This technology helps detect and track the stock that is inside your fridge and when you start running low, the RFID can be triggered to send a reminder as a notification on your email or a text message.

Answer:
ICT is the abbreviated form of Information and Communication. It included different technologies like mobile phones, computers, USBs etc.
Following are two precautionary measures which should be observed when using any kind of ICT:
- Use of Antivirus: It can used to protect anything placed inside the technology especially from hacking and viruses which can create many issues.
- Backup Data: Creating a backup of the data stored in the device is important as it can be recalled when the device malfunctions. Backup of the data can be created through using USBs, CDs etc or through cloud storage
Answer:
Advantages of both circuit switched networks and TDM are given below:
Explanation:
Advantages of circuit switched network over packet switched network:
- Circuit switched network has the advantage of being physically connected and having a dedicated channel for communication between the sender and the receiver which also makes it more reliable. Packet switched networks do not have a dedicated channel hence, they are not that reliable.
- Circuit switched networks are used for voice calls because there is no timing jitter or delay in these types of networks while packet switched networks do not offer this advantage.
Advantages of TDM over FDM in a circuit switched network:
- TDM is time division multiplexing i.e. multiple information is sent in different time intervals but on the same frequency. While FDM sends information using different frequencies. So, the advantage of using TDM is that the information will be sent from the sender to the receiver using only a single frequency.
- Using TDM, bandwidth is saved because it only sends information on a single frequency unlike FDM.
- In TDM, there is low chance of interference between signals since they are sent in different time intervals from the sender to the receiver. While FDM has a higher chance of interference.
