The datajack was invented in the 2491 by a Sivadian by the name of Dylan Phelps to allow hackers and other computer elite to quickly and efficiently interface the humanoid brain with 95% of computer technology, allowing the user to 'jack' themselves into systems via a simple computer cord and run commands using only thoughts. It wasn't until 2512 that the datajack was available to Shohobian races, and in 2526, limited download capability was introduced.
