Protocol
- Set of rules for communication so that devices can communicate effectively and reliably
- Developed in layers
- TCP/IP
- Transmission Control Protocol/Internet Protocol
- Layers
- Application
- Where the network applications function (email, websites etc.)
- Email
- POP (Post Office Protocol)
- Sends the only copy of the email to your device
- Only downloads email onto a single computer
- Used for inbound emails
- Sends the only copy of the email to your device
- IMAP (Internet Message Access Protocol)
- Sends a copy of the email to you
- Can be downloaded onto multiple computers
- Used for inbound emails
- Sends a copy of the email to you
- SMTP (Simple Mail Transfer Protocol)
- Used for outbound emails
- Goes from Client to Mail Server to Internet
- Uses domain names
- Used for outbound emails
- FTP (File Transfer Protocol)
- Handles Uploads and downloads
- Usually sends unviewable content
- Can be replaced with HTTP
- Handles Uploads and downloads
- HTTP (HyperText Transfer Protocol)
- Links websites using Hypertext Links
- Is used to access websites on a webpage
- Can be HTTPS for more secure connections
- Links websites using Hypertext Links
- POP (Post Office Protocol)
- Where the network applications function (email, websites etc.)
- Transport
- A connection is set up between 2 hosts, the rules are agreed (Packet size etc)
- TCP (Transmission Control Protocol)
- This splits or assembles the packeted data
- Acknowledges that the data is sent, this is a form of error checking
- This splits or assembles the packeted data
- A connection is set up between 2 hosts, the rules are agreed (Packet size etc)
- Network
- Packets are addressed/put into packets
- Finds the route between nodes to sent the data
- IP (Internet Protocol)
- Addresses the source of the data/the destination of the data
- Once the data is sent, the IP addresses are removed from the packets
- Addresses the source of the data/the destination of the data
- Packets are addressed/put into packets
- Link
- This is the hardware layer
- Hubs/Switches/Device Drivers
- Hubs/Switches/Device Drivers
- Ethernet
- A family of protocols
- Segment, Format, Send
- Packets are formed at the link layer
- An ethernet cable links hardware devices
- A family of protocols
- WiFi
- A family of protocols
- Made up of radio waves which pass through the air
- The data is encrypted using WPA (WiFi Protected Access)
- Split up into channels with a designated frequency
- However different channels can also clash
- Advantages
- A remote connection so is easy to use
- Cheap and easy setup
- Easily Expandable
- A remote connection so is easy to use
- Disadvantages
- Interference can occur between channels
- Often it can be slower
- It has a limited range
- Can be unreliable
- Vulnerable to hacking
- Interference can occur between channels
- A family of protocols
- This is the hardware layer
- Application
- Transmission Control Protocol/Internet Protocol
