1.5 Network Topologies V2
- The majority of computers are connected together through via networks.
- A network is a unit of computers linked together to allow them to
contribute resources they have done to other users.
- Networked computers can share hardware, software and data.
- Networks are all around you; school, at home, in businesses and hospitals.

- Topology
- Mesh
Network
- Where some or all of the workstations or other devices are
connected directly to each other. most are usually connected to
the noode that they exchange the most data with.

- Star
Network
- In a star network, each device is connected by an
individual cable directly to the server. Star networks are
usually the layout of choice in schools and offices
because they tend to be the most reliable of the
topologies.

- Wifi
- Encryption
- Ethernet
- Topology
- Ethernet
- Stable connection, reduction possibility to be hacked, more secure,
faster traffic speed, generally will have a good quality signal
- Stable connection, reduction possibility to be hacked, more secure,
faster traffic speed, generally will have a good quality signal
- Wifi
- Cheap set up costs , more vulnerable to
hacking, the signal quality will reduce
through walls or obstructions, can
connect multiple devices without the
need for extra hardware
- Interference can occur, less disruption to the building due to no wires being installed,
user not tied down to a specific location, may not be able to receive signal, the
connection is not as stable as wired network and can 'drop off'. Tend to have slow
transfer speeds

- IMAP - Used to retrieve emails.
HTTP - Used to retrieve email.
SMTP - Used to send emails.
- Upgrading from a b series to a n series
make faster data transmission due to
the fact of additional bandwidth
carrying more non-overlapping
channels, less interference.
- The encryption process
- 1)Client requests HTTPS session
- 2) Certificate sent to client from
the server
- 3)Client creates session key
- 4) Session encrypted with session key
- 5) The session key is decrypted with the private key
- 6) Session encrypted with session key
