1A LAN is a l[blank_start]ocal[blank_end] a[blank_start]rea[blank_end] n[blank_start]etwork[blank_end] and is o[blank_start]wned[blank_end] by the person or organisation. A WAN is a w[blank_start]ide[blank_end] a[blank_start]rea[blank_end] n[blank_start]etwork[blank_end] which is h[blank_start]ired[blank_end] from another company
- Aocal
- Brea
- Cetwork
- Dwned
- Eide
- Frea
- Getwork
- Hired
2Switches connect d[blank_start]evices[blank_end] in a network, routers connect different n[blank_start]etworks[blank_end]. They both transmit d[blank_start]ata[blank_end]
- Aevices
- Betworks
- Cata
3Wired connections are better because it doesn't rely on s[blank_start]ignal[blank_end] qu[blank_start]ality[blank_end] or any i[blank_start]nterference[blank_end]
- Aignal
- Bality
- Cnterference
4A WAP (W[blank_start]ireless[blank_end] a[blank_start]ccess[blank_end] p[blank_start]oint[blank_end]) is like a s[blank_start]witch[blank_end] but for w[blank_start]ireless[blank_end] connections rather than w[blank_start]ired[blank_end]
- Aireless
- Bccess
- Coint
- Dwitch
- Eireless
- Fired
5Bluetooth has a low b[blank_start]andwidth[blank_end], direct c[blank_start]onnection[blank_end] with the device and often used with m[blank_start]obile[blank_end] d[blank_start]evices[blank_end]
- Aandwidth
- Bonnection
- Cobile
- Devices
6Wi-Fi can be used for multiple d[blank_start]evices[blank_end], longer r[blank_start]ange[blank_end] than Bluetooth and a higher b[blank_start]andwidth[blank_end]
- Aevices
- Bange
- Candwidth
73 factors that affect a network's performance:
1. B[blank_start]andwidth[blank_end] (the amount of d[blank_start]ata[blank_end] transferred in a given time)
2. Amount of d[blank_start]evices[blank_end]
3. Ph[blank_start]ysical[blank_end] o[blank_start]bstructions[blank_end]- Aysical
- Bbstructions
- Cevices
- Dandwidth
- Eata
8In a C[blank_start]lient[blank_end]-s[blank_start]erver[blank_end] network, [blank_start]clients[blank_end] have to request data from the [blank_start]server[blank_end]. Everything has to go through the [blank_start]server[blank_end]
- Aerver
- Blient
- Cclients
- Dserver
- Eserver
9Pros of using a peer-to-peer network: No d[blank_start]ependence[blank_end] on the s[blank_start]erver[blank_end] and easy to m[blank_start]aintain[blank_end]
- Aependence
- Berver
- Caintain
10Cons of using a peer-to-peer: Lose track of f[blank_start]iles[blank_end] and less r[blank_start]eliable[blank_end] with d[blank_start]ata[blank_end]
- Ailes
- Bata
- Celiable
11Pros of a Client-server network: Easy to keep track of f[blank_start]iles[blank_end] and easy to manage s[blank_start]ecurity[blank_end] and u[blank_start]pdates[blank_end]
- Ailes
- Becurity
- Cpdates
12Cons of a client-server network: It's e[blank_start]xpensive[blank_end] and it is d[blank_start]ependant[blank_end] on the s[blank_start]erver[blank_end]
- Axpensive
- Bependant
- Cerver
13Pros of a star topology: If a device f[blank_start]ails[blank_end], the n[blank_start]etwork[blank_end] is fine, and there are few d[blank_start]ata[blank_end] c[blank_start]ollisions[blank_end]
- Aails
- Betwork
- Cata
- Dollisions
14Cons of a star topology: It's e[blank_start]xpensive[blank_end] and if the s[blank_start]erver[blank_end] goes down, the n[blank_start]etwork[blank_end] goes down
- Axpensive
- Berver
- Cetwork
15Standards are important because m[blank_start]anufacturers[blank_end] can c[blank_start]reate[blank_end] programs and products c[blank_start]ompatible[blank_end] with other ones
- Aanufacturers
- Bompatible
- Create
16A protocol is a s[blank_start]et[blank_end] of r[blank_start]ules[blank_end] on how devices c[blank_start]ommunicate[blank_end] and send d[blank_start]ata[blank_end] over n[blank_start]etworks[blank_end]
- Aet
- Bules
- Communicate
- Detworks
- Eata
17MAC addresses are u[blank_start]nique[blank_end] to each computer and are used by s[blank_start]witches[blank_end].
IP addresses are a[blank_start]ssigned[blank_end] to a device when they join a n[blank_start]etwork[blank_end].- Anique
- Bwitches
- Cssigned
- Detwork
18IPv6 has 2 to the power of [blank_start]128[blank_end] different addresses
- A128
19TCP prepares the data to be sent. It splits it into p[blank_start]ackets[blank_end] and r[blank_start]eassembles[blank_end] it afterwards.
IP directs the p[blank_start]ackages[blank_end] to their d[blank_start]estination[blank_end]
HTTP used to access w[blank_start]ebsites[blank_end] and c[blank_start]ommunicate[blank_end] with servers
FTP accesses, moves and edit f[blank_start]iles[blank_end] between d[blank_start]evices[blank_end]
POP3 [blank_start]retrieves[blank_end] emails then deletes the original.
IMAP [blank_start]retrieves[blank_end] emails
SMTP [blank_start]sends[blank_end] emails- Aackets
- Beassembles

20The DNS t[blank_start]ranslates[blank_end] the d[blank_start]omain[blank_end] name into an IP a[blank_start]ddress[blank_end] so you don't have to. It has a network of D[blank_start]omain[blank_end] Name Servers which have a list of IP a[blank_start]ddresses[blank_end] and d[blank_start]omain[blank_end] names
- Address
- Bomain
- Comain
- Dddresses
- Eomain
- Franslates
21The Cloud uses the I[blank_start]nternet[blank_end] to store f[blank_start]iles[blank_end] and a[blank_start]pplications[blank_end]
- Anternet
- Biles
- Cpplications
22Pros of using the Cloud:
Access files on any c[blank_start]onnected[blank_end] device
Easy to increase s[blank_start]torage[blank_end]
Don't have to buy expensive h[blank_start]ardware[blank_end]
Provides s[blank_start]ecurity[blank_end] and b[blank_start]ack-ups[blank_end]
U[blank_start]pdated[blank_end] automatically- Aonnected
- Btorage
- Cardware
- Decurity
- Eack-ups
- Fpdated
23Cons of using the Cloud:
Need c[blank_start]onnection[blank_end] to the Internet
D[blank_start]ependant[blank_end] on host
V[blank_start]ulnerable[blank_end] to hackers
Unclear who has o[blank_start]wnership[blank_end]
Subscription fees could be e[blank_start]xpensive[blank_end]- Aonnection
- Bependant
- Culnerable
- Dwnership
- Expensive
245 prevention methods for attacks:
T[blank_start]est[blank_end] the network to find w[blank_start]eaknesses[blank_end]
Use strong p[blank_start]asswords[blank_end]
Enforce u[blank_start]ser[blank_end] a[blank_start]ccesses[blank_end] l[blank_start]evels[blank_end]
Install a[blank_start]nti-malware[blank_end] and a f[blank_start]irewall[blank_end]
E[blank_start]ncryption[blank_end]- Ancryption
- Bnti-malware
- Cirewall
- Dccess
- Eevels
- Fser
- Gasswords
- Heaknesses

25Passwords need to be m[blank_start]any[blank_end] characters, be changed r[blank_start]egularly[blank_end] and have a combination and l[blank_start]etters[blank_end], n[blank_start]umbers[blank_end] and s[blank_start]ymbols[blank_end].
- Aymbols
- Bumbers
- Cetters
- Degularly
- Eany
26Firewalls block u[blank_start]nauthorised[blank_end] access by examining all data e[blank_start]ntering[blank_end] and l[blank_start]eaving[blank_end], and stopping p[blank_start]otential[blank_end] t[blank_start]hreats[blank_end]
- Aotential
- Bnauthorised
