Networking Concepts: IPv4, IPv6, and More

IPv4 vs IPv6

• IPv6 has a larger address space than IPv4.
• IPv4 uses 32 bits for addresses while IPv6 uses 128 bits.
• IPv6 was designed to address the exhaustion of IPv4 addresses.

POST Method

• Sends data to a server.

Port 110

• Used for the Post Office Protocol 3 (POP3) email protocol.

Thermal Paste

• Used to improve heat transfer between the CPU and its heatsink.

Reverse Proxy

• Distributes incoming requests to multiple servers.
• Can be used to improve load balancing and performance.

Latency

• The time it takes for a data packet to travel from its source to its destination.

TCP vs UDP

• TCP is connection-oriented, meaning it establishes a connection before sending data.
• UDP is connectionless, meaning it does not establish a connection before sending data.
• TCP is slower than UDP because it ensures reliable delivery of data.
• UDP is faster because it does not guarantee data delivery.

Class B IP Address

• A Class B IP address starts with the range 172.16 to 172.31.

OSI Model & Logical Addressing

• Logical addressing is handled by the Network layer (Layer 3) of the OSI model.

Disk Cleanup

• Deletes unnecessary files to free up disk space.

Event Viewer Filtering

• Event Viewer allows filtering events by event type, source, and date.

Firewall Types

• Firewalls can be hardware or software-based.
• Software firewalls run on a device and provide network protection.
• Hardware firewalls are dedicated physical devices that provide network security.

Ethernet Cable Color Code Standard

• Uses the TIA/EIA 568A and TIA/EIA 568B standards.

Chart Creation in OpenOffice Calc

• Charts can be created using the "Insert" -> "Chart" menu.

Software Updates

• Software updates improve the security and stability of applications and operating systems.
• They can also add new features or fix bugs.
