Networks

?
How big is a LAN
Small geo area
1 of 16
How big is a PAN
Very short geo area
2 of 16
Benefits of networks(5)
Sharing files, Share hardware, Update all software at once, Communicate easily/cheaply using emails, Login from any device
3 of 16
Drawbacks of networks(4)
Expensive to setup, Vulnerable to hacking, If servers go down the whole network is disrupted, Employ specialists
4 of 16
What is a NIC
A Network Interface Card is a piece of hardware inside a device that allows it to connect to a network.
5 of 16
what is a switch
They are used to connect devices on a LAN
6 of 16
What is a fibre optic cable
They are cables that transmit data as light and travel long distance without interference and a high bandwidth
7 of 16
What are CAT5e and CAT6 cables
CAT5e and CAT6 cables are types of Ethernet cables That contain pairs of twisted copper wires
8 of 16
What are coaxial cables
They are made of a single copper wire surrounded by a plastic layer for interference and a metallic mesh to provide shielding form outside interference
9 of 16
How do wireless networks transmit data
Radiowaves
10 of 16
Benefits of wireless networks(3)
Convenient since you can move around, They are cheaper, It is easy to add more users
11 of 16
Drawbacks of wireless networks(3)
Less secure, Distance from WAP-interference, Lower bandwith
12 of 16
Pros of Star topology(4)
If a device fails-the rest of the network is unaffected, Easy to add more users, Better performance, Very few data collisions
13 of 16
Cons of Star topology(4)
Expensive since every device needs a wire, The switch is expensive, If the switch fails-the whole network is affected, Limited devices based on the switch
14 of 16
Pros of Bus topology(3)
Unaffected if a device fails, Does not depend on a central switch, Cheaper
15 of 16
Cons of Bus topology(4)
More data collisions, unsuitable for large networks, slower, If the bus cable breaks-the whole network fails
