Study Notes
Pythagoras' Theorem
- The equation representing Pythagoras' theorem is a² + b² = c², where a and b are the lengths of the two shorter sides and c is the length of the hypotenuse.
Right-Angled Triangles
- If the lengths of the two shorter sides are 3 and 4, the length of the hypotenuse is √(3² + 4²) = 5.
- If one side of a right-angled triangle is 8 and the hypotenuse is 10, the length of the other side is √(10² - 8²) = 6.
Networking
Packet Structure
- A network packet has a header and a payload.
- The main role of the header in a network packet is to provide information about the packet.
Packet Switching and Circuit Switching
- Packet switching differs from circuit switching in that packet switching breaks data into packets and transmits them independently, while circuit switching dedicates a communication channel between two devices.
Packet Analysis
- Packet sniffing is primarily used to capture and analyze network packets to understand network communication and diagnose issues.
IPv4 and IPv6
- One significant difference between IPv4 and IPv6 packet structures is that IPv6 headers do not include checksums, whereas IPv4 headers do.
