2A [blank_start]network[blank_end] is created when more than one [blank_start]device[blank_end] is connected together.
A network can be a small collection of computers connected within a [blank_start]building[blank_end] (eg a school, business or home) or it can be a wide collection of [blank_start]computers[blank_end] connected around the world.- Adevice

4In a [blank_start]star[blank_end] network, each device on the network has its own cable that connects to a switch or hub.
This is the most popular way of setting up a [blank_start]LAN[blank_end].
You may find a star network in a small network of five or six computers where speed is a priority.
Advantages
very reliable – if one cable or device fails, then all the others will [blank_start]continue[blank_end] to work
high performing as no data collisions can occur
Disadvantages
[blank_start]expensive[blank_end] to install as this type of network uses the most cable, and network cable is expensive
extra hardware is required - hubs or [blank_start]switches[blank_end] - which add to the cost
if a hub or switch fails, all the devices connected to it will have no [blank_start]network[blank_end] connection- Astar

5In a [blank_start]bus[blank_end] network all the workstations, servers and printers are joined to one cable - 'the bus'.
At each end of the cable a terminator is fitted to stop signals reflecting back down the bus.
Advantages
easy to [blank_start]install[blank_end]
cheap to install - it does not require much [blank_start]cabling[blank_end]
[blank_start]Disadvantages[blank_end]
if the main cable fails or gets damaged, the whole network will fail
as more [blank_start]workstations[blank_end] are connected, the performance of the network will become slower because of data collisions
every workstation on the network 'sees' all of the [blank_start]data[blank_end] on the network, which can be a [blank_start]security[blank_end] risk- Abus

7[blank_start]Wireless[blank_end] connection
Computers can make a wireless connection if they have a wireless NIC. A wireless router provides a [blank_start]connection[blank_end] with the physical network. A computer device needs to be within range of the [blank_start]router[blank_end] to get access. A wireless connection uses [blank_start]radio[blank_end] signals to send data across networks. The wireless [blank_start]adapter[blank_end] converts the data into a radio signal and the wireless receiver [blank_start]decodes[blank_end] it so that the computer can understand it.
Wireless [blank_start]transmissions[blank_end] can be intercepted by anyone within range of the router. Access can also be restricted to specific [blank_start]MAC[blank_end] addresses, and transmissions are usually [blank_start]encrypted[blank_end] using a key that works with WPA (wi-fi protected access).- AWireless
