Jabber 

These are packets that are greater than the maximum octets (specified for the system by the configuration software) long and with either CRC or alignment error(s).

 

Jack Type

Different types of jacks (RJ-11, RJ45 or RJ-48) can be used for an ISDN line. The RJ-11 is the most common in the world and is most often used for analog phones, modems and fax machines. RJ-48 and RJ-45 are essentially the same, as they both have the same 8-pin configuration. An RJ-11 jack can fit into an RJ-45/RJ-48 connector, however, an RJ-45/RJ-48 cannot fit into an RJ-11 connector.

 

Jam Signal

In Ethernet networks, when a transmitting station detects a collision, it stops transmitting and sends a 32-bit jam sequence to inform other stations to (momentarily) stop transmitting so that it can transmit.

 

Java Permissions

Java is a computer language often used in software that is accessed via your web browser. In order for some software to operate properly you need to allow Java to execute.

 

JavaScript Permissions

JavaScript is a scripting language for the Internet. It is used in software that is accessed via your web browser. In order for some software to operate properly you need to allow JavaScripts to execute.

 

JBOD

JBOD, meaning "Just a Bunch Of Disks" or "Just a Bunch Of Drives", allows you to combine multiple physical disk drives into a single virtual one, so they appear as a single large disk. JBOD can be used to turn several different-sized drives into one big disk drive. See also RAID.

 

Jumbo Frames

Jumbo frames are used to forward non-standard packet sizes on your network. Jumbo frames can support delivery of up to 9216 bytes instead of standard Ethernet frames of 1522 bytes. The bigger the frame, the better the network performance. Fewer packets are required for large data transfer, improving traffic throughput on the port.
