Its fixed packet size.
The optimum size for a mini laptop screen is 7". This is the smallest size for a mini laptop and they range in sizes from there. You can always visit a store to find out about other sizes.
Frame Size
The Ethernet cable may be too big to fit through the wall, depending on the size of the cable and the size of the opening in the wall.
An Ethernet frame typically has a maximum payload size of 1500 bytes, which includes the APR (Address Resolution Protocol) packet. The APR packet itself is relatively small, usually around 28 bytes, allowing the Ethernet frame to accommodate additional headers and trailers, such as the Ethernet header (14 bytes) and the Frame Check Sequence (4 bytes). Therefore, the total size of an Ethernet frame carrying an APR packet would be at least 64 bytes (minimum frame size) up to 1518 bytes (maximum frame size).
Totally depends on the hardware and software and their MTU (Maximum Transmission Unit). Usually MTU is set to 1500 bytes.
28 byte
The minimum size of an Ethernet frame is 64 bytes. Even if the VLAN tag is 4 bytes, the Ethernet frame with VLAN tagging remains 64 bytes.
The best practices for securing Ethernet cables with Ethernet cable clips include ensuring the clips are the right size for the cable, using clips that are designed for Ethernet cables, placing the clips at regular intervals along the cable, and avoiding bending or crimping the cable excessively.
Maybe the ethernet cable is not your problem. Ethernet cables are available everywhere and they all should work for the PS3, PC, router, modem, etc. ethernet ports are one way and are either in or out. The spot on back of the PS3 to connect an ethernet is a standard size and is meant to connect to a modem or a router or it will not work.
cost and oil production value.
The "optimum size" of something is the size that cannot be any higher or larger or bigger or heavier, etc for carryying out a certain task. It depends what sort of stuff and what sort of task we are talking about. "Optimum" means "greatest"
