Your Network: Friends and Family

When we talk about our friends and family, we are essentially discussing a network of connections. This network allows us to communicate, share stories, news, and even showcase our beloved pets. The essence of being 'connected' in this context means being linked or joined to people we know well.

• Talking: Communication is key within a network.
• Sharing: Sharing stories and pictures strengthens these connections.
• Telling: Updating others with news helps maintain relationships.
• Showcasing: Displaying our pets or personal moments fosters bonding.

When we count the individuals in our network, we are essentially counting the number of people we are connected to.

Connecting Computers

Similar to our personal networks, computers and digital devices can also form connections with each other. This connection enables them to exchange information, facilitating the sharing of messages, words, pictures, stories, and videos.

• Information Sharing: Connected devices can exchange data and share information seamlessly.
• Communication: Devices can send messages and share various forms of media.

Computer Networks

• When multiple computers and digital devices are linked together, they form what is known as a computer network. 
• This network allows for enhanced communication and data exchange among the connected devices.

How Computers are Connected

• Network Connections
  • School computers are often connected to form a network, allowing them to share information and communicate.
  • For example, in a school setting, multiple computers can be connected to a network, enabling students and teachers to share files and resources easily.
• Sharing Devices
  • Devices within a network can share resources, such as printers, reducing the need for multiple devices.
  • When computers are connected in a network, they can all use a single printer, making printing more efficient and cost-effective.
• Wired Connections
  • Computers and devices can be connected using cables, which are thick wires used to transmit data between devices.
  • For instance, Ethernet cables are commonly used to connect computers to a local network or the internet.
• Wireless Connections
  • Some devices can be connected wirelessly using technology like Wi-Fi, which allows data to be transmitted through the air.
  • Wi-Fi technology enables devices to connect to the internet and communicate with each other without the need for physical cables.
