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.
Camcorder
In early 2014 Sony released the FDR-AX100 which represents the next generation of camcorders. It is capable of shooting in 4K resolution. It currently has a price tag of £1,699 and 4K camcorders are not expected to come into the mainstream market for at least another eight to ten years as most current Blu-ray players are not capable of playing 4K video. Virtually all mainstream TVs are not 4K ready either with the only 4K TVs available being very expensive at £2,500 or over. The only means of archiving 4K video is the 100 GB Blu-ray Disc XL but the discs are very expensive.
