Q

what are the pros and cons of having one centralized computer connected to all other computers in the network

A

Con: if a side computer wants to to get to another side computer, it must first go through central computer.
if something happens to central computer… network is screwed
Pro: simple layout and you only have to keep all info on one machine
if one of the side computers goes down, it doesn’t affect all other machines in the network

Q

what are the pros and cons of having a peer to peer connected network (where each computer is connected to two other computers, kind of forming a circle)
everyone is on the same level

A

Pros: if one computer goes down, there is a secondary path for the other computers, just going the other way around in the circle
Cons: if two computers go down, then you can’t access all computers - not the most reliable system

Q

what does the internet use

A

uses TCP/IP
TCP/IP has no direct line at the outset of the message! If a communication line is broken, another line is tried.
A standard protocol (way of communicating),
Opposite of your home telephone where you get a direct line that only you and the person you are talking to can use.

Q

how does the internet work using TCP IP

describe process

A
  1. it breaks things down into packets
    tcp takes the info (eg email) and breaks it down into packets (all of equal size)
    each packet has a header (where theyre coming and where are they going - IP address of source and destination) and a body containing the information transferred.
  2. tcp then sends it out to the internet, sending the packet to the first IP Address on the route… were each packet can take various routes but the all end up at the same location
    TCP DOESNT PREPLAN ROUTE
  3. tcp reassembles the info as it arrives at the destination

Q

What does TCP do at the receiving end

A

Detects lost packets, packets with errors because of network congestion, traffic load balancing, or other unpredictable network behaviour, and requests the packet to be resent from the source
Rearranges and reassembles the packets back into the webpage, email message, etc on the receivers machine

Q

describe packet switching

A

TCP breaks webpage into packets of bytes
TCP figures out IP address of where it wants to send the packets (destination)
TCP figures out IP address of where the packet is coming from (source)
Sends off each packet to first machine (IP Address) on the route (DOES NOT PREPLAN ROUTE!)
Packet stops at first machine, likely a router, then the router sends it to the next machine on the journey (IP Address) and so on until it gets to the final IP Address (destination)

Q

what is IP and what does it do

A

the way to identify each computer - Address
Each machine has its own address, called an IP Address
Like a GPS
Picks a route for a packet, stopping at routers which pick the next best machine/network to send the package to.
If a communication line is down or broken, sends the package back to TCP and TCP sends it again to try a different route.

Q

how does a domain name work

A 
Every machine on the internet gets an IP Address
A DNS (Domain Name System) maps the domain name to the correct IP address.
In most cases there is a one to one mapping between an IP Address and a Domain Name

Continual Connection: The server needs a 24/7 high speed connection to the internet, which is relatively costly.
Technical: Setting up all the configurations including mail server, FTP server and DNS server can be complicated.
Support: Server maintenance requires 24 hour support, special skills and knowledge.

84

Rogers
Bell
Execulink
Western (at least while you are a student here)

87
Q

what to look for in an ISP

A

Disk Space  Always get more, Standard 5 GB – 10 GB
Bandwidth  bandwidth is the amount of traffic that is allowed to occur between your web site and the rest of the internet in a given time period (static pages go with low; need for downloads go with high)
Web Site Speed  Web site speed is a given… slow.. Poor service (ask for some websites and try it out yourself)
Database/Programming Language Support  Needs for dynamic website – interact with customers. Perl, Java, PHP etc…
Technical Support  Test by sending them an e-mail and see response time, Contact names, e-mails, phone numbers, hotlines
UpTime  Look for 99% plus guaranteed
FTP Access  Unlimited and unrestricted FTP access for easy maintenance
Web Statistics Summary:  Traffic on your website- Easy access to your information… control
Scripts availability  counters, forms support.
Web Provider  Reliability? How long? Popular?

88
