What are the network infrastructure that contains three categories of network components?
What is an End Device?
A device that human use and interact with.
What is an Intermediary Device?
Intermediary devices interconnect end devices
Name what types of end devices?
Computers (work stations, laptops, file servers, web servers)
Mobile handheld devices
Name what type of Intermediary devices
Network Access (switches and wireless access points)
What is a network medium?
Metallic wires within cables
Glass or plastic fibers (fiber optic cable)
What are the advantages and disadvantages of Copper cables?
Cheap easy to work with?
Distance is of cable is restricted to 100m, electrical interference affect the data signal.
What are the advantages and disadvantages of fiber cables?
Can transmitted faster data of longer distances
The cost of the cable is expensive
hard to work with
The size of the fiber is smaller than a human hair.
What are the advantages and disadvantages of Wireless?
Easy to setup
Can work a large distance
the cost is not expensive
Transmission is subject to interference
data can be intercepted
requires power to work.
What is a Local Area Network (LAN)
A network infrastructure that provides access to users and end devices in a small geographical area.
What is a Wide Area Network (WAN)
A network infrastructure that provides access to other networks over a wide geographical area.
What is a Metropolitan Area Network (MAN)
A network infrastructure that spans a physical area larger than a LAN but smaller than a WAN (e.g., a city). MANs are typically operated by a single entity such as a large organization.
What is the internet?
The Internet is a worldwide collection of interconnected networks (internetworks or internet for short), cooperating with each other to exchange information using common standards.
What is the intranet?

What is the Extranet?
An organization may use an extranet to provide secure and safe access to individuals who work for a different organizations, but require company data.
What is Fault Tolerance?
Redundant connections allow for alternative paths if a device or link fails?
What is Scalability?
Additional users and whole networks can be connected to the internet without degrading performance
What is Quality of Service (QoS)?
It is managed by the router ensures that priorities are matched with the type of communication and it importance to the organization.
What is Security?
protecting the network with software and hardware.
Preventing psychical access to the devices.
What is Circuit-Switched?
A temporary path, or physical circuit, is created for the duration of the connection
What is a Packet-Switched?
a single message can be broken into multiple message blocks, with each message block containing addressing information to indicate the origination point and final destination.
What is Bring Your Own Device (BYOD)?
means any device, with any ownership, used anywhere
What is Online Collaboration?
