    The word yo probably comes from the Ilocano term yóyo, or a cognate word from the Philippines. A Greek vase painting from 440 BC shows a boy playing with a yo-yo (see right). Greek records from the period describe toys made out of wood, metal, or painted terra cotta (fired clay).The terra cotta disks were used to ceremonially offer the toys of youth to certain gods when a child came of age—discs of other materials were used for actual play.

    Sleeping

    The sleeper is one of the most common yo-yo throws and is the basis for nearly all yo-yo throws other than looping. Keeping a yo-yo spinning while remaining at the end of its uncoiled string is known as sleeping. While the yo-yo is in the "sleeping" state at the end of the string, one can then execute tricks like "walk the dog", "around the world", or the more complex "rock the baby". The essence of the throw is that one throws the yo-yo with a very pronounced wrist action so that when the yo...

    Unresponsive

    Eventually, wider string gaps and silicone response systems led to the innovation of unresponsive yoyoing, otherwise known as 1A. Traditional yoyos (responsive) would return to the hand when one would tug on the string, but unresponsive yoyos behave a little differently. Instead of returning to the hand when you tug on the string, you have to perform a trick called a "bind" where the string is doubled over inside the string gap to increase friction on the response system. This has brought abo...

    Looping

    Looping is a yo-yo technique which emphasizes keeping the body of two yo-yos, one on each hand, in constant motion, with or without sleeping. Yo-yos optimized for looping have weight concentrated in their centers so they may easily rotate about the string's axis without their mass contributing to resistance due to a gyroscopic effect. In yo-yo competitions, looping both to the inside and outside of the hand with the yo-yo plays a strong role in the 2A division. Sometimes the yoyos would wrap...

    When the yo-yo is first released, the gravity (and the throw) give it translational kinetic energy and necessarily, since the string must unwind, much of this energy is converted into rotational kinetic energy establishing the free movement of the yo-yo, and causing it to spin rapidly. As the yo-yo unwinds downward, it also converts potential energy from gravityto both translational agh energy in its rotation to overcome gravity all the way back up to the hand. Because the sense of spinning does not change during the whole move, the string winds up in the opposite direction upon the return of the yo-yo. If the shaft of the yo-yo is connected to the string with a loop, there may not be enough frictional force to overcome the weight of the yo-yo, which is necessary to begin winding up the string. In this case, the yo-yo will continue to spin in the loop at the end of the string (or sleep), just being slightly braked by the small dynamic friction, instead of returning. However, if the...

Customers in certain locations can obtain a Skrill Card linked to their account. The card lets customers use their account balance to pay in stores or online where Skrill is not listed as a payment option. The Skrill Card can also be used to withdraw cash at ATMs. Customers who meet certain spending thresholds are offered Skrill VIP membership which includes lower fees, higher transaction limits and dedicated support, among others. Skri...

    Skrill was named Best Digital Wallet in 2019 by Juniper Research at their Future Digital Awards. Paysafe, Skrill's parent company, received the Payments Processor of the Year award at the 2019 American Gambling Awards for the Skrill digital wallet and sister product Paysafecard. In 2019 Paysafe won the ‘Best Online Payments Solution – Consumer’ at the Payments Awards. The accolade recognised Paysafe's suite of online consumer payment methods, including its digital wallets Skrill and Neteller.

    In August 2010, Skrill blocked the account operated by WikiLeaksas a donation collection account, citing the organisation's addition to Australian blacklists and American watchlists.

    Each port implements a bidirectional synchronous serial channel.The channel is slightly asymmetrical: it favors transmission from the input device to the computer, which is the majority case. The bidirectional IBM AT and PS/2 keyboard interface is a development of the unidirectional IBM PC keyboard interface, using the same signal lines but adding capability to send data back to the keyboard from the computer; this explains the asymmetry. The interface has two main signal lines, Data and Clock. These are single-ended signals driven by open-collector drivers at each end. Normally, the transmission is from the device to the host. To transmit a byte, the device simply outputs a serial frame of data (including 8 bits of data and a parity bit) on the Data line serially as it toggles the Clock line once for each bit. The host controls the direction of communication using the Clock line; when the host pulls it low, communication from the attached device is inhibited. The host can interrupt...

    Older laptops and most contemporary motherboards have a single port that supports either a keyboard or a mouse. Sometimes the port also allows one of the devices to be connected to the two normally unused pins in the connector to allow both to be connected at once through a special splitter cable. This configuration is common on IBM/Lenovo Thinkpadnotebooks among many others. The PS/2 keyboard interface is electrically the same as the 5-pin DIN connector on earlier AT keyboards, and keyboards designed for one can be connected to the other with a simple wiring adapter. Such wiring adapters and adapter cables were once commonly available for sale. Note that IBM PC and PC XT keyboards use a different unidirectional protocol with the same DIN connector as AT keyboards, so though a PC or XT keyboard can be connected to PS/2 port using a wiring adapter intended for an AT keyboard, the earlier keyboard will not work with the PS/2 port. (At least, it cannot work with normal PS/2 keyboard dr...

    Original PS/2 connectors were black or had the same color as the connecting cable (mainly white). Later the PC 97 standard introduced a color code: the keyboard port, and the plugs on compliant keyboards, were purple; mouse ports and plugs were green. (Some vendors initially used a different color code; Logitechused the color orange for the keyboard connector for a short period, but soon switched to purple.) Today this code is still used on most PCs. The pinouts of the connectors are the same, but most computers will not recognize devices connected to the wrong port.

    Hotplugging

    PS/2 ports are designed to connect the digital I/O lines of the microcontroller in the external device directly to the digital lines of the microcontroller on the motherboard. They are not designed to be hot swappable. Hot swapping PS/2 devices usually does not cause damage because more modern microcontrollers tend to have more robust I/O lines built into them which are harder to damage than those of older controllers;however, hot swapping can still potentially cause damage on older machines,...

    Durability

    PS/2 connectors are not designed to be plugged in and out very often, which can lead to bent or broken pins. Additionally, PS/2 connectors only insert in one direction and must be rotated correctly before attempting connection. (If a user attempts to insert the connector in the wrong orientation and then tries to rotate it to the correct orientation without first pulling it out, then bent pins could result.) Most but not all connectors include an arrow or flat section which is usually aligned...

    Fault isolation

    In a standard implementation both PS/2 ports are usually controlled by a single microcontroller on the motherboard. This makes design and manufacturing extremely simple and cheap. However, a rare side effect of this design is that a malfunctioning device can cause the controller to become confused, resulting in bothdevices acting erratically. (A well designed and programmed controller will not behave in this way.) The resulting problems can be difficult to troubleshoot (e.g., a bad mouse can...
