Types of Networks

100

This network topology has one cable connecting all the nodes. If this cable goes down then the network shuts down.

What is a bus topology?

200

What is efficiency, effectiveness, management, reach and customer service? (Teacher is allowed to choose acceptable answers)

300

The network is spread over only a small area.

What is a LAN (or Local Area Network)?

400

This topology is a combination of a bus and a star topology.

What is a hybrid/tree topology

500

This type of network enables users with the same networking software and the internet to connect one another's hard disks and exchange files directly.

What is Internet peer-to-peer network?

Communication Devices and Software

100

This machine converts a computers digital signal into an analogue signal before it is transmitted over standard telephone lines.

What is a modem?

200

This is inserted in an expansion slot of a personal computer (or built in to the computer's motherboard) that allows the device network capability so it can communicate with a network.

What is a network interface card (NIC)?

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?

400

This device provides a connecting point for cables in a star, bus or hybrid LAN.

What is a switch?

500

This device is used to connect multiple area networks (e.g. several LANs or a LAN and a WAN).

What is a router?

Communication Channels

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?

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?

300

These waves provide high-speed signal transmission. They can transmit data up to 4500 times faster than a dial-up modem.

What is microwaves?

400

To use this, an IrDA port is included with many mobile computers and devices, such as a printer and a mouse.

What is Infra-red?

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?

Mobile Devices

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?

200

These devices are an Internet-enabled mobile phone with features including an address book, calendar and a calculator.

What is a smart phone?

300

This app was the most popular app in 2009.

What is TomTom?

400

This is a small, lightweight and inexpensive laptop computer suitable for general computing and Internet-based applications.

What is a netbook?

500

This is what PDA stands for.

What is Personal Digital Assistant?

Network Communications Standards

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

This is what Mbps stands for?

What is megabits per second?

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 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

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?
