Network and Data
Communication
• Introduction
• Network Connectivity Devices
• Types of Networks
• Internet for teaching learning
• Online Assessment tools
3. Introduction
• A network can either be a small group of two or
more devices linked together or a high-end network
that links hundreds or even millions of devices
• Network can be used
• to share resources (such as printers and CDs)
• exchange files
• allow electronic communications.
• The sharing of data reduces the need for duplication
and helps to reduce the workload of those on the
network.
4. Practice; sharing printer
• In Windows 10, you can take a printer, plug it into
one computer, and then print from another.
• The steps has been shown below;
• Before you can share a printer, it must first be set up,
connected, and powered on.

Devices and Printers link. Right-click your printer,
then click Printer properties.

multiple devices running a mixture of Windows client
architectures – 32 or 64 bit-you should enable the “Render

• End-user devices include computers, printers, scanners,
and other devices that provide services directly to the user.
• Network devices include all the devices that connect the
end-user devices together to allow them to communicate
which includes hubs, bridges, switches, and routers.
11. • Hub - connect multiple networking devices together.
• Bridge - Bridges are used to connect two or more
network segments together.
12. • Switch - have a more intelligent role than hubs in
sending the data by MAC address to the destination
address which improves network efficiency.
13. • Routers is interconnected networking devices using different
network topologies that has also the capabilities of other
connectivity devices.
• Access Point - While an access point (AP) can technically
involve either a wired or wireless connection, it commonly
means a wireless device.

devices connected together over a small area (up to few

instant communication and sharing resources over a large
geographical area.
