The primary difference between DVD+R and DVD-R is the type of recorder used to write the discs. DVD-R is an older format that dates back to 1997, while DVD+R is a newer recording technology created in 2002. The two types of discs hold the same amount of information, but DVD+R discs are less susceptible to write errors. Most modern DVD players read both types of discs.Know More
DVD+R allows faster and more accurate disc recording than the existing DVD-R standard. The two formats are incompatible with each other, and neither has market dominance. To handle both formats, most DVD readers employ a hybrid technology that reads both types of discs. Because DVD-R is an older standard, some computers, DVD players and game consoles from 2004 and earlier only read DVD-R discs. People with older equipment must be sure to use DVD-R discs in place of DVD-RW discs.
Both types of discs come in rewritable and dual-layer formats. Rewritable DVDs can be erased and rewritten many times, making them reusable. Dual-layer DVDs hold twice as much information as a standard DVD by using two recordable layers instead of one. This is different from double-sided DVDs, which can be flipped to record a second disc on the other side of the DVD.Learn more in Television & Video

Digital information is stored using two discrete values, while analog information is typically stored using nondiscrete signals. Since the advent of digital technology, the term "analog" has been used to refer to nondigital storage and transfer technology.Full Answer >
The difference between UHF, ultra-high frequency, and VHF, very high frequency, is that the frequencies used in UHF are much higher than those in VHF. Both, however, are relatively high frequencies for radio waves as the names imply. Signals sent via VHF are less directional and travel further than UHF signals, making them preferable for their typical purpose of broadcasting television.Full Answer >
