Jini network technology or simply "Jini" is a network architecture that helps in building distributed systems and owes its inception to "Sun Microsystems." According to Sun Microsystems, "Jini network technology, which includes JavaSpaces Technology and Jini extensible remote invocation (Jini ERI), is an open architecture that enables developers to create network-centric services -- whether implemented in hardware or software -- that are highly adaptive to change. Jini technology can be used to build adaptive networks that are scalable, evolvable and flexible as typically required in dynamic computing environments."

Jini helps in dealing with some of the flaws of Distributed Computing as assumed by the programming world such as: zero latency, infinite bandwidth, network is secure, reliable and homogeneous, etc. Jini helped in dealing with the system evolution issues, security and dynamic assembly of service components. Jini also helped in enhancing the ability of the network to maintain an adequate level of service while undergoing various faults. Jini actively helps in “Code Mobility” which is an important concept pf the platform, and also provides many benefits that include non-protocol dependence.

Jini provides its users with great and consistent access to various hardware and software resources within a dynamic, distributed Jini system called "djinn.”  This networked accessibility of software and hardware entities is termed by Jini as “federation.”
