What is digital data?
Digital data is discrete data that is used in computers to handle all sorts of digital media, including text, graphics and audio. It only exists in two forms - on and off. This is represented with two digits- 1s and 0s - in the binary format. Since digital data is discrete, files saved in this format can be copied perfectly with no degradation.
Should you use teflon tape on a water temp sensor?
Most likely not. If the sensor reads hot it will short to ground through its casing and trip the warning signal. The tape can prevent it from reaching ground.
How does a Backup tape work?
A backup tape works by copying information from a computer and storing it. If something happens to a computer or a hard drive, a backup tape still has the information that was also stored on the hard drive of a computer.
Which type of media is typically used for large data backups?
DLT tape
What are the Application of merge sort in real life?
It is used in tape drives to sort data - its good with parallel processing, which is why it is used there.
Reads and writes data and information on a tape?
drive
What are the purpose of tape drive?
Data storage device that reads and writes data on a magnetic tape.
How are magnets used in tape recorders?
A cassette tape is based totally off of a magnetic system. The magnet is what reads and writes the information to the tape.
What read and writes information on a tape?
A tape drive.
How does the HP LTO Ultrium x - 400 GB Storage Media unit work?
This is an example of a tape drive. A tape drive is a storage device that stores, reads, and writes data on a magnetic tape. Read and write heads, allow the tape drive to copy data from a source onto magnetic tapes placed inside the drive.
What is a tape drive?
A device, like a tape recorder, that reads data from and writes it onto a tape. Tape drives have data capacities of anywhere from a few hundred kilobytes to several gigabytes. Their transfer speeds also vary considerably. Fast tape drives can transfer as much as 20MB (megabytes) per second. The disadvantage of tape drives is that they are sequential-access devices, which means that to read any particular block of data, you need to read all the preceding blocks. This makes them much too slow for general-purpose storage operations. However, they are the least expensive media for making backups.

What writes on duct tape?
Sharpie writes on EVERYTHING
Why are video tape recorders built with rotating video heads instead of static ones?
The video data is striped diagonally across the tape so more data can be saved on the tape. The rotating head is angled and writes the data in stripes, this essentailly stacks the data using most of the width of the tape. The rotation allows the head to move faster than the tape speed to accomodate the increased data storage. The remaining width of the tape is used for audio which is recorded in two continuous stripes.
What is serial random and parallel access What types of storage devices use each method Which ones do you use on your computer?
Serial- reads and writes in sequence. Like a cassette tape and maybe a floppy not sure. Random- Can read and write between non continuous data. CD, DVD. Parallel-reads and writes portions of data in parallel using separate lines or mediums. Such as an Ethernet cable- its made up of about 8 wires each wire sends a bit of data parallel with 7 other bits to send 8 total bits in parallel .

What type of storage requires sequential access to locate data and information?
a tape
Does a tape player have a magnet in it?
Yes, a tape player typically has a magnetic head that reads the magnetic information encoded on the tape. The magnetic head uses a magnet to convert the magnetic signals on the tape into electrical signals that can be amplified and reproduced as sound.
What is the function of tape drives?
A tape library stores information about tape drives, magnetic strips of tape that read and write data such as those used in video cassettes and floppy discs. Tape libraries hold tape cartridges and read tap barcodes for identification.
