Is there a word starting with the letter j that means strong or helpful?

Answer 1

= JavaScript

A scripting language developed by Netscape Communications and Sun Microsystems that is loosely related to Java. JavaScript, however, is not a true object-oriented language, and it is limited in performance compared with Java because it is not compiled. Basic online applications and functions can be added to Web pages with JavaScript, but the number and complexity of available application programming interface functions are fewer than those available with Java. JavaScript code, which is included in a Web page along with the HTML code, is generally considered easier to write than Java, especially for novice programmers. A JavaScript-compliant Web browser, such as Netscape Navigator or internet Explorer, is necessary to run JavaScript code. = = job queue = = A list of programs or tasks waiting for execution by a computer. Jobs in the queue are often ordered according to some basis of priority. = = Jukebox

Software that is designed to play a list of sound files in a user-specified order reminiscent of jukeboxes used to play vinyl records. = = Jumper (computing) = In electronics and particularly computing, a jumper is two or more connecting points that can be conveniently shorted together to setup or adjust a printed circuit board, such as a computer's motherboard.

Jumpers are arranged in groups called jumper blocks, each group having at least one pair of contact points and often more. In general, each contact in a jumper block terminates in a small metal pin. An appropriately sized conductive sleeve called a shunt is slipped over the pins to complete the circuit. (In everyday usage, shunts are very commonly but incorrectly called "jumpers".) = Jitter = Abrupt and unwanted variations of one or more signal characteristics, such as the interval between successive pulses, the amplitude of successive cycles, or the frequency or phase of successive cycles. (188) Note 1: Jitter must be specified in qualitative terms (e.g., amplitude, phase, pulse width or pulse position) and in quantitative terms (e.g., average, RMS, or peak-to-peak). Note 2: The low-frequency cutoff for jitter is usually specified at 1 Hz. Contrast with drift, wander. = Jerkiness = In a video display, the perception, by human vision faculties, of originally continuous motion as a sequence of distinct "snapshots." Note 1: The perception of continuous motion by human vision faculties is a manifestation of complex functions, i.e., characteristics, of the eyes and brain. When presented with a sequence of fixed, i.e., still, images of sufficient continuity and at a sufficiently frequent update rate, the brain interpolates intermediate images, and the observer subjectively appears to see continuous motion that in reality does not exist. Note 2: For example, the update rate of NTSC television displays is 30 frames (60 fields) per second. = Jam signal = A signal that carries a bit pattern sent by a data station to inform the other stations that they must not transmit. Note 1: In carrier-sense multiple access with collision detection (CSMA/CD) networks, the jam signal indicates that a collision has occurred. Note 2: In carrier-sense multiple access with collision avoidance (CSMA/CA) networks, the jam signal indicates that the sending station intends to transmit. Note 3: "Jam signal" should not be confused with "electronic jamming." = Jajah = Jajah is a proprietary peer-to-peer internet telephony (VoIP) softphone. With Jajah you can speak to other Jajah-, SIP-, IAX- or Skype-users for free. = Jabber = In local area networks, transmission by a data station beyond the time interval allowed by the protocol.
