How magnets are used in recording?
Magnets are or rather were used to record audio or video on cassettes media earlier (which had/have magnetic tape in them on which data was recorded using magnet), which have now (still used) but taken over by optical media (CDs, DVDs, Blurays). Hard Disks/Drives in computer also use magnets to record on them.
What about collecting data most determines whether or not it is accurate?
Recording data properly.
What is the noting and recording of facts and events for scientific study called?
Observation and collection of data.
What is a data center?
A place where we can process, store and deliver the digital information is called data center. Many data centers are available worldwide.
What are the advantages of using digital data and other new technology in surveying?
Andrew's mum.
Are compact discs digital recordings?
The data written onto compact discs is in a digital format. It may not have originally been written in a digital format, but will be converted to digital in order to write it to a compact disc. Some music/audio compact discs show whether the data was digital or analogue at each stage of: * original recording * mixing * recording to CD by showing a three letter code where A indicates analogue and D digital. ADD would indicate an original analogue recording with a digital mixing and then the digital compact disc recording.
Magnetic tape backup?
Magnetic tape backup of your data is done with a magnetic tape data storage system. You can use digital recording to store your digital data on the magnetic tape as a backup.
What has the author Irwin Lebow written?

What is a card reader used for?
A SDHC Card Reader is used to read secure digital cards. Secure digital cards are used for recording data on digital cameras, GPS devices, phones and tablets.
In recording what is a mike?
It is a short word for microphone, used in recording the actual sound. it changes sound waves into electrical signals.
Facts about digital camcorders?
Sony developed the first digital camcorder that recorded uncompressed data and in 1995, they came out with the DV standard. Formats for digital camcorders include direct to disk recording and Digital8. Digital camcorders now record in MPEG formats.

What is magnetic data storage?
A magnetic storage device is a device that uses a magnetic head to read and write data to and from a magnetizable medium. The medium can be as basic as a plastic tape that is coated with fine particles of a metal, such as is found in audio recording and tape storage devices.
How magnets are used in recording?
Magnets are or rather were used to record audio or video on cassettes media earlier (which had/have magnetic tape in them on which data was recorded using magnet), which have now (still used) but taken over by optical media (CDs, DVDs, Blurays).

What is encoding technique?
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Identify types of communication data that are stored or transmitted in digital form?
Many types of communication data are stored or transmitted indigitalform:¨Fibre optics communication data – phone calls, computer data¨Mobile telephone calls¨Sound and picture recordings on magnetic tape, Compact Discs (CD’s) and Digital Versatile Discs (DVD’s)¨Computer data itself – the huge volume of data available on the internet, computerized records kept by businesses, banks, governments, local councils, the police and military and so on.¨Digital TV signals & Digital Audio Broadcasting (DAB) signals - DAB combines two technologies – digital sound recording & data compression.¨Communications satellites utilise very small aperture terminals (VSATs) which relay digital data for a multitude of business services.¨Holographic data - holograms can store large quantities of data by varying the recording angle relative to the photographic plate.To retrieve the data the hologram must be illuminated with a laser beam at different angles.¨“Smart” weapons – eg tomahawk missiles can be launched over 1000 km from the target and follow precise directional instructions to reach its target.
What would you call a device that works with binary data?
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
