Question | Answer |
network | system that permits different applications on different host to work together |
network application | app's that are based on networking-ie Obama's email app on Black berry |
Web 2.0 | users provide content-Wikipedia |
Social Media App's | designed to facilitate group relationships.-facebook |
Host | any device(computer, printer, toaster) connected to a network |
network core | central part of network |
access links | what users use to connect to network, may be copper wire, fiber optic cables or radio transmissions |
Dumb terminal | network that could only connect with central host and show ntwks on the screen. not interactive |
Server/Client processing | server program, on server host, provides services to a client program, on a client host, very interactive |
request-response cycle | online shopping- when client server sends a request of server host and receives a response from a webserver, not the direct host |
P2P | peer to peer networking where client and host work directly with host |
cloud computing | servers for internal company are being managed by outside company |
bps | bits per second measures speed of network |
BPS | Big B= bytes per second |
kbps | kilo 1000 |
Mbps | Mega 1000 kbps |
Gbps | Giga 1000 Mbps |
Tbps | Tera 1000 giga |
Dial up | Way to connect terminals and host over llong distances, circuit is terminated after you hang up |
circuit switching | gives you a reservered opacity between you and other party; circuit remains even after done connecting- no matter how many people on other lines service will not be bad because you have a reserved amount of data already |
bursty | connection/data transmission during dail up durst of good and followed by long silence when ple are on the phone |
leased line circuit | relays mainly on dial up and if phone is being used then leases time on circuit switching (which is 24 hour line available line) |
analog signal | rises and flows in intensity, like human voice |
binary transaction | only 1 states in this type of connection 1 and 0- type of digital transmission |
modems | translate digital to analog sytems |
modulation | digital to analog |
demod | talk talk talk to 011 011 |
amplitude modulation | one represented by a LOUD signal LLSL =1101 |
Clock cycle | to differenate amplitude modulation i.e. two soft sounds in a row |
Packet Switching | saves money by multiplexing(mixing in data with phone convos) over expensive circuits |
forwarding decision | packet switch decides to send the message along based on it's address |
physical links | in packet switch network, these are between host, switchs and there routers |
data links | name for switches path that packets take |
IMPS | intereface message processors, packet switch network in ARPA net, fragmented network |
NCP | Network Control Program, for IMPS's in ARPA net, to deliver and rebuild packets |
NWG | networking working group standarized IMP connections, |
RFCs | Request for Comments made by NWG, i.e. need for sender and receiver address |
IETF | internet Engineering Task Force the new NWG |
PRnet and SATnet | using packet transmiting through radio packets and sateilight packets |
routers/gateways | Kahn and Cerf made these. ways to connect different networks into a router |
internet layers | higher layer of networking over different kinds of network technology |
dotted decimal notation | human reading of ipv address like 123.235.343.92 |
frames | packets at the data link layer |
packects | packets on the internet(2 layer with ipv4 passcodes) |
switches | the packet switch that frame goes through in a network |
routers | the packet switch that a packet goes through in the internet "route" |
transport layer | 4th layer in internetworking right above internet only cares about what happens from host server to destination server |
IP | internet protcool these standards deal with your IP address purpose: to move packets around internet |
TCP | transport control protocol with high functionality, this fragments application message |
UDP/Datagrams | User Datagram Protocol- not high functionality, no fragments or error correction VoIP(voice over techonology uses this) |
TCP/IP | family of standards including IP TCP and UDP |
What 3 networks first tried internet | PRNET-stany, ARPANET AND SATNET-bayshore |
AUP | Acceptable Use Policy, NSNET bought this regulatory company to keep internet as strictly research, no bullying, ads |
NAPs | Networking Access Points different routers that allow ISP to exchange packets |
supervisory standards | now TCP/IP standards are more geared towards user application like Web and email standards |
static IP address | unchanging ip addresses that servers must have, so users can always find them. |
DHCP | dynamic Host Configuration Protcol gives users/Client PC ip address to surf the web |
Dynamic IP address | changing IP address, used by client PC's like me ;) |
DNS | Given by NIC (network info center) this is the human friendly name for ipaddress. like gap.com is 234.543.234.56 |
LANS | local area network conststite inside a corporation; cheaper and can choose techolongy self inplementation speed: 100 Mbps to 10 Gbps |
WANs | Wide area networks, connects different networking sites within and organization speed: 256 kbps to 50 Mbps- Gov regulates this and more expensive |
Carries/Right of way | gov issues to WAN permission where to lay wires |
wireless access router in home | connects networks(i.e. mobile and regular) has an eternet switch |
NAT (inhome) | network Address translation; translate internal versus single IP add. given to household |
