A MAN network is a network that covers a large region. It covers areas larger than a LAN, but less than a WAN. MAN stands for metropolitan area network. An example of a MAN is a few buildings or a city. It sometimes connects multiple networks

# data[].attributes.body
A WAN is a network that extends over a large geographical area. An example of this is the internet. WAN stands for wide area network.

A LAN network is a network where devices share common communications. They are usually on a private network and connected to one central server. LAN stands for Local Area Network.

A cellular/mobile network is a network where the last link is wireless. The signal is distributed over areas called cells

# data[].attributes.body
A mesh network is when every single device is interconnected. This means that they can communicate directly. There are two types of networks; full, when every device are connected to each other. Then there is partial, where only certain devices are connected to each other. If one device goes down, others can still communicate.

A star network is where all of the devices on a network connect to one central hub. This is how they all communicate and is the most common form of network. If the central hub goes down, the whole network stops working.

# data[].attributes.body
A bus network is where each device is connected to one main cable called the data link. This is how the devices communicate on the backbone of the network.

# data[].attributes.body
A ring network is where one device connects to exactly two devices. This forms a single continuous pathway of a ring.

# data[].attributes.body
A point to point network topology is for allowing two endpoints or two nodes a way of communicating.

Token passing is allowing people to access certain areas and features of a network. This is by granting them certain 'tokens' to allow them to do so.

Cellular data is a mobile connection, usually for mobile phones, provided by cellular towers. They connect to the cells using radio waves and they will feed back to a hub that is giving them connection. The connection types can consist of 3G, 4G and 5G, beyond 2020

# data[].attributes.body
Bluetooth is a connection used for connecting devices over short distances, usually 5 or 10 meters. the connection type is short wavelength radiowaves.

# data[].attributes.body
A wireless signal is made up of radio waves. This is mainly used for personal networks and cellular data. A router will decode the signal and then send the information to the computer using it's wireless adapter.

A fibre optic cable is a bunch of thin, long strands of glass all bundled together, into something called optical cables. It emits signals using light.

# data[].attributes.body
A coaxial cable is a transmission line used for radio frequency signals.

# data[].attributes.body
Cat5e is similar to Cat5. The main difference is that it supports gigabit speeds and cuts down on cross-talk.

# data[].attributes.body
A Cat5 cable is a twisted cable that is mainly used for Ethernet connections. It can provide speeds of up to 100mbps.

What is the purpose of video conferencing?

# data[].attributes.body
The purpose of video conferencing is to have convenient meetings when it is not possible any other way. A good example is when you are trying to have a conference call with a client in Asia.

What is the purpose of text based messaging systems

# data[].attributes.body
The purpose of text based messaging systems is to communicate when it is not appropriate fort other methods. An example is when you are in a meeting and you can't talk using VOIP.

A web server is a program that uses hypertext transfer protocol. It basically forms web pages for users.

# data[].attributes.body
The purpose of a proxy server is a function used for security. It basically acts as a third party. The device gets the information for you and then you receive it anonymously. The other party does not know it was meant for you

What is the purpose of a network operating system?

# data[].attributes.body
A network operating system allows computers to do things such as collaboration and accessing printers. This is usually done over a LAN or a private network.

A gateway is a way of stopping traffic going in or out of a network. It allows computers withing the local network to send data over the Internet.

# data[].attributes.body
The purpose of a bridge is to pass packets between two separate networks that use the same network protocols. The bridge operates at the link layer, layer 2, in the OSI model. A bridge will filter, flood or forward an incoming frame based on the MAC address.

What is the purpose of a active, passive and intelligent hub?

# data[].attributes.subject
What is the purpose of a active, passive and intelligent hub?

# data[].attributes.body
The point of an active hub is that it repeats the signals on an output stage to keep the signals strong.
The point of a passive hub is that it joins wires from several stations into one central location. It does not process or regenerate any signals.
The point in an intelligent hub is to perform a variety of different networking functions. These can range from bridge management, bridging, switching and routing.

# data[].attributes.body
The purpose of a repeater in a network is that it repeats or strengthens signals that are weakened or have been distorted during transmission. This is mainly for devices that are further away from the router than is recommended.

What is the purpose of a Network Interface Card (NIC)?

# data[].attributes.body
The purpose of a NIC is to provide a wireless or wired connection to a computer. It is sometimes contained on the motherboard or as a separate piece of hardware.

A workstation is a high specification computer that is dedicated to carrying out a certain task. This means that it will offer higher performance than usual than the usual mainstream computers.

# data[].attributes.body
The purpose of a server in a network is to provide a service to another device or piece of software. The server usually runs the task that needs to be done on their end and then broadcasts it to the other device that controls the service.

# data[].attributes.body
A firewall on a network or a computer is a piece of software that is designed to give protection from outside attempts to gain unwarranted access to your network or computer. It does this by scanning the ports to see if any connections are showing an suspicious connections.

# data[].attributes.body
The purpose of a router is to give all devices on a network access to the internet. Either wired or wireless. The router connects directly to a modem which provides the internet connections on the network. It is a layer 3 device and has it's own unique I.P. address.

# data[].attributes.body
The switch is a hub that all of the devices connect to. This is so that it is easier to connect them all to a server or turn them all off. It can also be to easily connect all of the devices to a router and give them an internet connection through a router.
