100

 is a network setup where all devices are connected to a single central cable through which data is transmitted.

 bus topology

100
This machine converts a computers digital signal into an analogue signal before it is transmitted over standard telephone lines.
What is a modem?
100
This single copper wire is surrounded by at least three layers. It can be laid over a long distance but are not used that often.
What is coaxial cable?
100
These devices store programs and data permanently on a special memory inside the system unit or on a flash memory card.
What is a mobile device?
100
This is a standard communications protocol embedded in software and hardware devices that allows computers to operate a LAN.
What is the Ethernet?
200

 is a network protocol used in building automation systems (BAS) to control the data exchange between different devices and components, commonly used to control HVAC and lighting, manage security and access, monitor energy usage, and allow inter-operation with other building management systems.

BACNet

200

a secondary network distribution point that connects the main network hub to end-user devices within a building or campus.

Intermediate Distribution Frame (IDF)

200
The core of the cable consists of dozens or hundred of thin strands of glass or plastic that use light to transmit signals.
What is fibre-optic cable?
200

is a logical subdivision of a larger IP network. It allows administrators to split a single IP address block into smaller, more manageable segments, improving efficiency, security, and performance. 

Subnet

200
This is what Mbps stands for?
What is megabits per second?
300
The network is spread over only a small area.
What is a LAN (or Local Area Network)?
300

This is normally placed near the ceiling and allows computers and devices to transmit data wirelessly among themselves.

What is a wireless access point?

300

is a company or organization that provides users with access to the Internet and related services.

ISP

300

is a unique numerical label assigned to every device on a network, allowing it to be identified and located for communication.

IP Address

300
This standard was developed by IEEE to specify how two wireless computers or devices communicate via radio waves with each other.
What is the 802.11 standard?
400
This topology is a combination of a bus and a star topology.
What is a hybrid/tree topology
400
This device provides a connecting point for cables in a star, bus or hybrid LAN.
What is a switch?
400

 It serves as the central hub where external communication lines connect to the internal network. Is crucial for managing and routing data transmission within a building or campus, acting as the main point for all network cables.

 MDF (Main Distribution Frame)




400
This is a small, lightweight and inexpensive laptop computer suitable for general computing and Internet-based applications.
What is a netbook?
400
This is the name given to messages that need to be communicated over a network and have been broken down into smaller pieces.
What are packets?
500

is a crucial component in building automation systems (BAS) that provides control, monitoring, and management of connected systems.

Supervisor Device

500
This device is used to connect multiple area networks (e.g. several LANs or a LAN and a WAN).
What is a router?
500
This is one of the benefits of using a fibre-optic cable.
What is the capability of carrying significantly more signals than wire cables, faster data transmission, less susceptibility to noise (interference) from other devices, such as a copy machine, better security for signals during transmission as they are less susceptible to noise, their smaller size?
500
This is what PDA stands for.
What is Personal Digital Assistant?
500
This standard (four numbers between 0 and 255 separated by full stops - defines a mechanism to provide a unique address for each computer on the network.
What is the IP addressing standard?
