In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. [1]: 25 The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.g., Ethernet frame.
The default TCP Maximum Segment Size is for IPv4 is 536. For IPv6 it is 1220. [1]: §3.7.1 Where a host wishes to set the maximum segment size to a value other than the default, the maximum segment size is specified as a TCP option, initially in the TCP SYN packet during the TCP handshake.

z Uses 8b/10b encoding, meaning that 20% of each transfer is used by the interface instead of carrying data from between the hardware components at each end of the interface. For example, a single link PCIe 1.0 has a 2.5 Gbit/s transfer rate, yet its usable bandwidth is only 2 Gbit/s (250 MB/s).
Few systems transfer files and data by simply copying the contents of the file into the 'Data' field of HDLC or PPP frames — another protocol layer is used to format the data inside the 'Data' field of the HDLC or PPP frame. The most commonly used such protocol is Internet Protocol (IP), defined by RFC 791. This imposes its own overheads.
NetServer was a line of x86-based server and workstation computers sold by Hewlett-Packard (HP) from 1993 to 2002. [1] [2] It was Hewlett-Packard's first entry in the commodity local area networking (LAN) market. The NetServer line comprised a wide range of models featuring differing form factors and processor configurations.
Tomiko Itooka, who became the world's oldest living person, died last week at age 116. Brazilian nun Inah Canabarro Lucas is now the new world's oldest person.
In November 2011 HP announced Project Odyssey, a development roadmap to unify server architectures on a single platform. The roadmap includes blades with Intel Xeon processors for the HP Superdome 2 enclosure (code-named DragonHawk ) and the scalable c-Class blade enclosures (code-named HydraLynx ), while supporting Windows and Linux ...
