A LANMeter was a tool for testing Token Ring and Ethernet networks introduced by Fluke Corporation in 1993. It incorporated hardware testing (cable and network interface card) and active network testing in a handheld, battery operated package. It was discontinued in 2003.

A chi-squared test, also written as χ2 test, is a statistical hypothesis test that is valid to perform when the test statistic is chi-squared distributed under the null hypothesis, specifically Pearson's chi-squared test and variants thereof. Pearson's chi-squared test is used to determine whether there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table.
A television pilot is a standalone episode of a television series that is used to sell the show to a television network. At the time of its creation, the pilot is meant to be the testing ground to gauge whether a series will be successful. It is, therefore, a test episode for the intended television series, an early step in the series development, much like pilot studies serve as precursors to the start of larger activity.
Web development is the work involved in developing a Web site for the Internet or an intranet. Web development can range from developing a simple single static page of plain text to complex Web-based Internet applications, electronic businesses, and social network services. A more comprehensive list of tasks to which Web development commonly refers, may include Web engineering, Web design, Web content development, client liaison, client-side/server-side scripting, Web server and network security configuration, and e-commerce development.
An open proxy is a proxy server that is accessible by any Internet user. Generally, a proxy server only allows users within a network group to store and forward Internet services such as DNS or web pages to reduce and control the bandwidth used by the group. With an open proxy, however, any user on the Internet is able to use this forwarding service.
BACnet is a communication protocol for Building Automation and Control (BAC) networks that leverage the ASHRAE, ANSI, and ISO 16484-5 standard protocol.

In machine learning, a common task is the study and construction of algorithms that can learn from and make predictions on data. Such algorithms function by making data-driven predictions or decisions, through building a mathematical model from input data.
The Granger causality test is a statistical hypothesis test for determining whether one time series is useful in forecasting another, first proposed in 1969. Ordinarily, regressions reflect "mere" correlations, but Clive Granger argued that causality in economics could be tested for by measuring the ability to predict the future values of a time series using prior values of another time series. Since the question of "true causality" is deeply philosophical, and because of the post hoc ergo propter hoc fallacy of assuming that one thing preceding another can be used as a proof of causation, econometricians assert that the Granger test finds only "predictive causality". Using the term "causality" alone is a misnomer, as Granger-causality is better described as "precedence", or, as Granger himself later claimed in 1977, "temporally related". Rather than testing whether Ycauses X, the Granger causality tests whether Y forecastsX.
Johnny Test is an American-Canadian animated television series produced by Warner Bros. Animation from Seasons 1 to 2 and by Cookie Jar Entertainment from Seasons 2 to 6. It premiered on Kids' WB on September 17, 2005, which continued to air the series through its second and third seasons. The rest of the series aired on Cartoon Network starting on January 7, 2008, in the United States and internationally. In Canada, the show premiered on Teletoon on September 8, 2006.
The NFL Scouting Combine is a week-long showcase occurring every February at Lucas Oil Stadium in Indianapolis, where college football players perform physical and mental tests in front of National Football League coaches, general managers, and scouts. With increasing interest in the NFL Draft, the scouting combine has grown in scope and significance, allowing personnel directors to evaluate upcoming prospects in a standardized setting. Its origins have evolved from the National, BLESTO, and Quadra Scouting organizations in 1977 to the media event it has become today.
A network analyzer is an instrument that measures the network parameters of electrical networks. Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h-parameters. Network analyzers are often used to characterize two-port networks such as amplifiers and filters, but they can be used on networks with an arbitrary number of ports.

In telecommunications, Long-Term Evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported.
In telecommunications, 5G is the fifth generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones. 5G networks are predicted to have more than 1.7 billion subscribers worldwide by 2025, according to the GSM Association. Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. The main advantage of the new networks is that they will have greater bandwidth, giving higher download speeds, eventually up to 10 gigabits per second (Gbit/s). Due to the increased bandwidth, it is expected the networks will not exclusively serve cellphones like existing cellular networks, but also be used as general internet service providers for laptops and desktop computers, competing with existing ISPs such as cable internet, and also will make possible new applications in internet of things (IoT) and machine to machine areas. 4G cellphones are not able to use the new networks, which require 5G enabled wireless devices.
The Computing Technology Industry Association (CompTIA) is an American non-profit trade association, issuing professional certifications for the information technology (IT) industry. It is considered one of the IT industry's top trade associations. Based in Downers Grove, Illinois, CompTIA issues vendor-neutral professional certifications in over 120 countries. The organization releases over 50 industry studies annually to track industry trends and changes. Over 2.2 million people have earned CompTIA certifications since the association was established.
Starlink is a satellite internet constellation being constructed by SpaceX providing satellite Internet access. The constellation will consist of thousands of mass-produced small satellites in low Earth orbit (LEO), working in combination with ground transceivers. SpaceX plans to sell some of the satellites for military, scientific, or exploratory purposes. The SpaceX satellite development facility in Redmond, Washington houses the Starlink research, development, manufacturing, and orbit control. The cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be about US$10 billion.
The 2020 FIA Formula One World Championship is a motor racing championship for Formula One cars which marks the 70th anniversary of the first Formula One World Drivers' Championship. The championship is recognised by the governing body of international motorsport, the Fédération Internationale de l'Automobile (FIA), as the highest class of competition for open-wheel racing cars. Drivers and teams are scheduled to compete for the titles of World Drivers' Champion and World Constructors' Champion respectively.
