1Data is sent between networks by splitting it into equal sized packets
- AVerdadero
- BFalso
2The header has the control information such as [blank_start]destination[blank_end] address, [blank_start]source[blank_end] address and packet [blank_start]number[blank_end]
- Adestination
- Bsource
- Cnumber
3The payload is the content such as part of emails documents webpages et cetera
- AVerdadero
- BFalso
4A checksum number is a form of [blank_start]validation[blank_end] use to check the [blank_start]payload[blank_end] hasn't been corrupted during [blank_start]transit[blank_end]. The checksum total is calculated and [blank_start]matched[blank_end] to data received correctly.
- Avalidation
- Bpayload
- Ctransit
- Dmatched
5Routers use packet switches to direct data packets on the Internet and other IPnetworks
- AVerdadero
- BFalso
6The router reads the [blank_start]header[blank_end] and decide which [blank_start]way[blank_end] to send the packed the packet according to the IP [blank_start]rules[blank_end]
- Aheader
- Bway
- Crules
7Data transfer does not depend on network traffic packet do not take different routes to many packets at once don't matter
- AVerdadero
- BFalso
8When packets are received in the wrong order the receiving device uses the pocket numbers to reassemble them into the right order
- AVerdadero
- BFalso
9If packets have not been [blank_start]received[blank_end] within a certain time the network sends out a [blank_start]timeout[blank_end] message back to the [blank_start]sending[blank_end] device
- Asending
- Breceived
- Ctimeout
10When all date is received receipt confirmation of sent out of the sending device
- AVerdadero
- BFalso
11TCP/IP is the protocol that dictates the way data is sent between networks
- AVerdadero
- BFalso
12TCP set the rules for how devices connect on the network. In charge of collecting data into packets and reassembling the packets back to the original data on the receiving device
- AVerdadero
- BFalso
13internet protocol (IP) is responsible for packet switching
- AVerdadero
- BFalso
14Hypertext transfer protocol is used by web browser to access websites
- AVerdadero
- BFalso
15HTTPS is a more secure version of HTTP
- AVerdadero
- BFalso
16POP3 is a [blank_start]protocol[blank_end] that receives [blank_start]emails[blank_end] from the server. The server holds the email until you [blank_start]download[blank_end] it then delete it
- Aprotocol
- Bemails
- Cdownload
17[blank_start]IMAP[blank_end] retrieves emails from a server; the server [blank_start]holds[blank_end] them until you actually delete it, you only download a [blank_start]copy[blank_end]
- AIMAP
- Bholds
- Ccopy
18Simple mail transfer protocol is used to send emails between severs
- AVerdadero
- BFalso
19Network protocols are divided into layers
- AVerdadero
- BFalso
20Network layers are self contained this means the [blank_start]individual[blank_end] layers do their job without needing to know what is [blank_start]happening[blank_end] in the all the layers
- Aindividual
- Bhappening
21Each layer serves the layer above it. 1 servers 2, 2 servers 3 etc
- AVerdadero
- BFalso
22Layer 4 = [blank_start]application[blank_end] layer, layer [blank_start]3[blank_end]= transport layer, layer 2 = [blank_start]network[blank_end] layer, layer 1 = data [blank_start]link[blank_end] layer
- Aapplication
- B3
- Cnetwork
- Dlink
23The application layers turns data into websites and other applications etc
- AVerdadero
- BFalso
24The transport layer controls data [blank_start]flow[blank_end] for example splitting data into packets and checking [blank_start]packets[blank_end] are correctly [blank_start]received[blank_end] or [blank_start]sent[blank_end]
- Aflow
- Bpackets
- Creceived
- Dsent
25The network layer makes connections between networks, directing data packets and handling data traffic
- AVerdadero
- BFalso
26Data link layer is passing data over the physical netowkr
- AVerdadero
- BFalso
27The advantage of using liars is that it breaks down [blank_start]communication[blank_end] into manageable pieces, layers can be changed without [blank_start]affecting[blank_end] all the layers, set rules for each layer makes it [blank_start]compatible[blank_end] for any device
- Acommunication
- Baffecting
- Ccompatible
