Study Notes
Network Components
- A host or end device is any computer on a network.
- Servers provide information to end devices, including:
- Email servers that run email server software and are accessed by clients using client software.
- Web servers that run web server software and are accessed by clients using browser software.
- File servers that store corporate and user files, accessible by client devices.
- Clients are computers that send requests to servers to retrieve information.
Peer-to-Peer Network
- A device can be both a client and a server in a peer-to-peer network, which is only recommended for very small networks.
- Advantages of peer-to-peer networks include:
- Easy to set up
- Less complex
- Lower cost
- Disadvantages of peer-to-peer networks include:
- No centralized administration
- Not as secure
- Not scalable
- Slower performance
End Devices
- An end device is where a message originates from or where it is received.
- Data originates with an end device, flows through the network, and arrives at an end device.
Intermediary Network Devices
- Intermediary devices interconnect end devices, including:
- Switches
- Wireless access points
- Routers
- Firewalls
- Intermediary devices manage data as it flows through the network, including:
- Regenerating and retransmitting data signals
- Maintaining information about pathways in the network
- Notifying other devices of errors and communication failures
Network Media
- Network media carries communication across a network, including:
- Metal wires within cables (using electrical impulses)
- Glass or plastic fibers within cables (fiber-optic cable, using pulses of light)
- Wireless transmission (using modulation of specific frequencies of electromagnetic waves)
Network Trends
- The role of the network must adjust to new technologies and end user devices.
- Recent trends include:
- Bring Your Own Device (BYOD)
- Online collaboration
- Video communications
- Cloud computing
Bring Your Own Device (BYOD)
- BYOD allows users to use their own devices, giving them more opportunities and flexibility.
- BYOD includes devices such as:
- Laptops
- Netbooks
- Tablets
- Smartphones
- E-readers
- BYOD means any device, with any ownership, used anywhere.
Online Collaboration
- Online collaboration allows users to work with others over the network on joint projects.
- Collaboration tools include Cisco WebEx, which provides a way to instantly connect and interact.
- Collaboration is a high priority for businesses and education.
- Cisco Webex Teams is a multifunctional collaboration tool that allows users to:
- Send instant messages
- Post images
- Post videos and links
Learn about the advantages and disadvantages of peer-to-peer networks, including easy setup, lack of centralized administration, lower complexity, less security, lower cost, non-scalability, and usage for simple tasks such as file transfer and printer sharing. Understand the concept of end devices in network communication.
