1. In wireless networking, the wireless central point is called: c. Access Point
2. To connect computers on a wired network, we use: b. Switch
3. A computer network that is spread larger than LAN and smaller than WAN called: d. MAN

Answer in one word: -

1. Which computer network can be used only within an organization? LAN
2. Which part of the palette helps to add a Proximity sensor to MIT Inventor Apps? Sensor
3. In which topology, all the nodes are connected to a single common path? Bus
4. What was developed by MIT and helped to create Apps? App Inventor
5. Which protocol is used to send email over the internet? SMTP

Write the full forms of the following: -

1. SMTP – Simple Mail Transfer Protocol
2. NIC – Network Interface Card
3. ISP – Internet Service Provider
4. HTTP – Hypertext Transfer Protocol
5. FTP – File Transfer Protocol

Answer the Questions: -

1. What are the differences between a peer-to-peer network and a Client-server network?

   • In a peer-to-peer network, all computers are equal and can share resources directly with each other. In a client-server network, one or more computers act as servers, and the other computers are clients that request services from the servers.

2. Differentiate between LAN and WAN.

   • LAN (Local Area Network) is a network that connects computers in a small area like a home, office, or school. WAN (Wide Area Network) is a network that covers a large geographical area, connecting multiple LANs.

3. Write the different components of the MIT App Inventor window.

   • The MIT App Inventor window consists of the Designer and the Blocks Editor. The Designer is used to create the user interface of the app. The Blocks Editor is used to create the app's behavior.

4. What are Sensors? Name three different types of sensors available in App Inventor with their uses.

   • Sensors are components that can detect changes in the environment. In App Inventor, there are various types of sensors, including the Accelerometer Sensor (detects shaking and orientation), the Location Sensor (detects geographical location), and the Proximity Sensor (detects the presence of an object without any physical contact).

5. Write any two advantages of networking.

   • Networking allows for the sharing of resources, such as printers and files, and it enables communication and collaboration between users.

6. Write the steps to connect the mobile phone with App Inventor.

   • To connect a mobile phone with App Inventor, you need to install the MIT AI2 Companion app on your phone. Then, in the App Inventor window, click on "Connect" and select "AI Companion". A QR code will appear on the screen. Scan this code with the AI2 Companion app on your phone to establish the connection.
