The Modified Modular Jack (MMJ) is a small form-factor serial port connector developed by Digital Equipment Corporation (DEC). It uses a modified version of the 6P6C modular connector with the latch displaced off-center so standard modular connectors found on Ethernet cables or phone jacks cannot accidentally be plugged in. MMJ connections are used on Digital minicomputers, such as the PDP-11, VAX and Alpha systems, and to connect terminals, printers, and serial console servers.

The MMJ connector has six conductors, using a superset of the RS-423 serial communication standard. The six pins are Tx and Rx for the data transmission, their return paths, and DSR and DTR for handshaking. The transmit and receive signals are differential, i.e. each signal is the voltage difference between the line and its associated ground, as opposed to a voltage on a single connector relative to a common reference. The system can also emulate RS-232 signaling by combining the lower voltage sides of each signal to the RS-232 signal ground line.

When connecting two DTE devices such as a computer and a printer, the Digital BC16E crossover cable is used.

Thrustmaster is using the MMJ connector for connecting its line of rudder pedals and racing pedals to either USB via a proprietary Thrustmaster Adapter, or directly to a joystick or racing wheel.

The Lego Mindstorms sets, beginning with the NXT, used similar plugs for motors and sensors to prevent the connection of standard telephone cords.

CEA-909 uses the MMJ connector for control signals to a smart antenna, which can either physically or electrically rotate for maximum signal strength.

A SIM lock, simlock, network lock, carrier lock or (master) subsidy lock is a technical restriction built into GSM and CDMA mobile phones by mobile phone manufacturers for use by service providers to restrict the use of these phones to specific countries and/or networks. This is in contrast to a phone (retrospectively called SIM-free or unlocked) that does not impose any SIM restrictions.

Generally phones can be locked to accept only SIM cards with certain International Mobile Subscriber Identities (IMSIs); IMSIs may be restricted by:

Additionally, some phones, especially Nokia phones, are locked by group IDs (GIDs), restricting them to a single Mobile virtual network operator (MVNO) of a certain operator.

Most mobile phones can be unlocked to work with any GSM network provider, but the phone may still display the original branding and may not support features of the new carrier. Besides the locking, phones may also have firmware installed on them which is specific to the network provider. For example, a Vodafone or Telstra branded phone in Australia will display the relevant logo and may only support features provided by that network (e.g. Vodafone Live!). This firmware is installed by the service provider and is separate from the locking mechanism. Most phones can be unbranded by reflashing a different firmware version, a procedure recommended for advanced users only. The reason many network providers SIM lock their phones is that they offer phones at a discount to customers in exchange for a contract to pay for the use of the network for a specified time period, usually between one and three years. This business model allows the company to recoup the cost of the phone over the life of the contract. Such discounts are worth up to several hundred US dollars. If the phones were not locked, users might sign a contract with one company, get the discounted phone, then stop paying the monthly bill (thus breaking the contract) and start using the phone on another network or even sell the phone for a profit. SIM locking curbs this by prohibiting change of network (using a new SIM).

SIM locking is very common if subsidized phones are sold with prepaid contracts. It is important to note, however, that the technology associated with the phone must be compatible with the technology being used by the network carrier. A GSM cell phone will only work with a GSM carrier and will not work on a CDMA network provider. Likewise, a CDMA cell phone will only work with a CDMA carrier and will not work on a GSM network provider. Note that newer (2013+) high end mobile phones are capable of supporting both CDMA and GSM technologies, allowing customers to use their mobile devices on any network. Examples of these mobile devices are the Apple iPhone 5c, 6 and newer, Motorola's G4, G5, X Pure, Samsung's Galaxy S6, S7, S8 smart phones, mostly phones based on a Qualcomm Snapdragon chipset or radio.

In some jurisdictions, such as Canada, Chile, China, Israel, and Singapore, it is illegal for providers to sell SIM locked devices. In other countries, carriers may not be required to unlock devices or may require the consumer to pay a fee for unlocking.

Unlocking the phone, however, is almost universally legal. Additionally, it is often legal for carriers to force SIM locks for certain amounts of time, varying by region.

The New York University Tisch School of the Arts (commonly referred to as Tisch) is the performing, cinematic and media arts school of New York University.

Founded on August 17, 1965, Tisch is a training ground for artists, scholars of the arts, and filmmakers. The school is divided into three Institutes: Performing Arts, Emerging Media, and Film & Television. Many undergraduate and graduate disciplines are available for students, including: acting, dance, drama, performance studies, design for stage and film, musical theatre writing, photography, record producing, game design and development, and film and television studies.

The school also offers an inter-disciplinary "collaborative arts" program, high school programs, continuing education in the arts for the general public, as well as the Clive Davis Institute of Recorded Music, which teaches entrepreneurial strategies in the music recording industry. A dual MFA/MBA graduate program is also offered, allowing students to take coursework at both Tisch and NYU's Stern School of Business. It is located at 721 Broadway (the intersection of Broadway St. and Waverly Place), adjacent to the university's Department of Philosophy building and the Gallatin School of Individualized Study, in the Greenwich Village neighborhood of Lower Manhattan, New York City. In 2013, NYU opened a new technology hub on its Brooklyn campus called the Media and Games Network (MAGNET). Located at 2 MetroTech Center and, beginning in 2019, 370 Jay Street, MAGNET houses three Tisch programs: the Clive Davis Institute of Recorded Music, the Interactive Telecommunications/Interactive Media Arts programs (ITP & IMA), and the Game Center; these programs work in collaboration with departments in media technology from NYU's Tandon School of Engineering and Steinhardt School of Culture, Education, and Human Development.

As of 2019, 22 Academy Award winners, 17 Emmy Award winners, 12 Tony Award winners, and four Grammy Award winners have been affiliated with Tisch alumni and faculty. As of 2017, the school had more than 25,000 alumni working in the arts and related professions, and has more alumni in Broadway theatre than any other school for theater in the United States.

In computing, LBX, or Low Bandwidth X, was a protocol to use the X Window System over network links with low bandwidth and high latency. It was introduced in X11R6.3 ("Broadway") in 1996, but never achieved wide use. It was disabled by default as of X.Org Server 7.1, and was removed for version 7.2.

X was originally implemented for use with the server and client on the same machine or the same local area network. By 1996, the Internet was becoming popular, and X's performance over narrow, slow links was problematic.

LBX ran as a proxy server (lbxproxy). It cached commonly used information — connection setup, large window properties, font metrics, keymaps and so on — and compressed data transmission over the network link.

LBX was never widely deployed as it did not offer significant speed improvements. The slow links it was introduced to help were typically insecure, and RFB (VNC) over a secure shell connection — which includes compression — proved faster than LBX, and also provided session resumption.

Finally, it was shown that greater speed improvements to X could be obtained for all networked environments with replacement of X's antiquated font system as part of the new composited graphics system, along with care and attention to application and widget toolkit design, particularly care to avoid network round trips and hence latency.

A Stargate is an Einstein–Rosen bridge portal device within the Stargate fictional universe that allows practical, rapid travel between two distant locations. The devices first appear in the 1994 Roland Emmerich film Stargate, and thereafter in the television series Stargate SG-1, Stargate Atlantis, and Stargate Universe. In these productions, the Stargate functions as a plot device, allowing the main characters to visit alien planets without the need for spaceships or any other type of technology. The device allows for near-instantaneous travel across both interstellar and extragalactic distances.

Local usage details (LUD) are a detailed record of local calls made and received from a particular phone number. These records are regularly available to police in the United States with a court order, and were traditionally subject to the same restrictions as telephone tapping.

LUDs may be legally used by the police without first obtaining a warrant, as determined by Smith v. Maryland (1979).

Other terms for call records include CDR (call detail records) or SMDR (station message detail recordings). These terms normally apply to "raw call records" before they have been processed to apply locations and rates.
