Modular connector

A modular connector is an electrical connector that was originally designed for use in telephone wiring, but has since been used for many other purposes. Many applications that originally used a bulkier, more expensive connector have converted to modular connectors. Probably the most well known applications of modular connectors are for telephone jacks and for Ethernet jacks, both of which are nearly always modular connectors.

Modular connectors were originally used in the Registration Interface system, mandated by the Federal Communications Commission (FCC) in 1976 in which they became known as registered jacks. The registered jack specifications define the wiring patterns of the jacks, not the physical dimensions or geometry of the connectors of either gender. Instead, these latter aspects are covered by ISO standard 8877, first used in ISDN systems. TIA/EIA-568 is a standard for data circuits wired on modular connectors.

Other systems exist for assigning signals to modular connectors; physical interchangeability of plugs and jacks does not ensure interoperation, nor protection from electrical damage to circuits. For example, modular cables and connectors have been used to supply low-voltage AC or DC power and no clear standard exists for this application.

P5 (microarchitecture)

The first Pentium microprocessor was introduced by Intel on March 22, 1993. Dubbed P5, its microarchitecture was the fifth generation for Intel, and the first superscalar IA-32 microarchitecture. As a direct extension of the 80486 architecture, it included dual integer pipelines, a faster floating-point unit, wider data bus, separate code and data caches and features for further reduced address calculation latency. In 1996, the Pentium with MMX Technology (often simply referred to as Pentium MMX) was introduced with the same basic microarchitecture complemented with an MMX instruction set, larger caches, and some other enhancements.

The P5 Pentium competitors included the Motorola 68060 and the PowerPC 601 as well as the SPARC, MIPS, and Alpha microprocessor families, most of which also used a superscalar in-order dual instruction pipeline configuration at some time.

Intel's Larrabee multicore architecture project uses a processor core derived from a P5 core (P54C), augmented by multithreading, 64-bit instructions, and a 16-wide vector processing unit. Intel's low-powered Bonnell microarchitecture employed in Atom processor cores also uses an in-order dual pipeline similar to P5.

2C2P

2C2P is a Singapore-headquartered pan-ASEAN payment services company. It was founded in 2003 by Aung Kyaw Moe, an entrepreneur from Myanmar who is based in Singapore and Thailand. In addition to establishing 2C2P, Aung has also co-founded Paysbuy, a Thai payments company, in 2004.

2C2P works with financial institutions, e-commerce and m-commerce merchants. It is headquartered in Singapore and has offices across Southeast Asia, including in Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines and Thailand, as well as in Hong Kong.

The company processed over $2.2 billion in transactions in FY2014. 2C2P has received financial backing from venture capitalists Amun Capital, GMO Venture Partners and Digital Media Partners. 2C2P was listed by Deloitte as one of only three Singaporean businesses, and among the fastest growing regional technology companies in the 2013 Deloitte Technology Fast 500 Awards. In 2015, it was named among the Top 25 payment startups by CB Insights, alongside Square Inc., Stripe (company), Adyen.

C2P

C2P was a Polish artillery tractor. Designed in the 1930s, it was the basic tractor of Polish anti-aircraft artillery during the 1939 Nazi and Soviet invasion of Poland. There are only two surviving vehicles, both in private hands in Poland.

Development

The origins of the design can be traced to the Carden Loyd tankette of the 1920s. In 1929 Poland bought 10 or 11 Mark VI tankettes with a licence for their production, and used them for development of their own TK tankette series. In October 1931 Polish General Staff expressed interest in a small, highly mobile artillery tractor intended for 75 mm field guns in Polish service at the time. In 1932 Janusz Łapuszewski and A. Schmidt of the BBTBP institute ("Armoured Forces Technical Study Bureau") designed a small, fully tracked artillery tractor based on TK-3 tankette. It was designed to tow the 40 mm Bofors and 75 mm wz. 36 anti-aircraft guns, but it could also tow other light and medium artillery used by the Polish Army, including modernised 75 mm Schneider guns and 100 mm Skoda howitzers. For heavier guns it was to be eventually replaced in Polish service with the PZInż 343 wheeled tractor, but only a couple of these were completed before the war.

C4P

Samochód półgąsienicowy wz. 34 (literally "Half-track car, Mark 1934") was a Polish halftrack lorry. It was produced in a variety of variants, the best-known of them being the C4P artillery tractor used by the Polish Army in the period before World War II.

The vehicle was based on a 2.5 tonne Fiat 621 truck, licence-built by Polski Fiat in Poland at the time. In 1934 Edward Habich of the Bureau for Technical Studies of the Armoured Arms (BBT BP) designed a half-track version of the Fiat 621 lorry, initially dubbed the Mark 1934 halftrack cargo lorry (Polish: Półgąsienicowy samochód ciężarowy wz. 34).

Both Fiat 621 and wz. 34 shared the majority of parts, notably the slightly modified frame, the engine and the crew compartment. There were many notable differences as well though. The front axle was reinforced, a reduction drive was added and the gearbox was modified to better suit the new vehicle. Most notably, the rear axles were replaced with a continuous track system modelled after the Vickers E tank and French Citroën-Kegresse half-tracks.
