4K (computer virus)
4k is a computer virus which infects COM files and EXE files. The virus was one of the first to employ stealth tactics. Infected systems will hang, after September 22 every year, which is also the date of birth Bilbo Baggins, a character from "The Lord of the Rings". The code was intended to display the message "Frodo Lives", but hangs in all known variants.
PlayStation 4
On June 10, 2016, Sony confirmed that a hardware revision of the PlayStation 4, rumored to be codenamed "Neo", was under development. The new revision is a higher-end model that is meant to support gameplay in 4K. The new model will be sold alongside the existing model, and all existing software will be compatible between the two models. Layden stated that Sony has no plans to "bifurcate the market", only that gamers playing on the Neo will "have the same experience, but one will be delivered at a higher resolution, with an enhanced graphical experience, but everything else is going to be exactly as you'd expect". The high-end console was publicly revealed on September 7, 2016, as PlayStation 4 Pro. At the same time, Sony unveiled an updated version of the original PS4 model with a smaller form factor.
