Removable Media in Computer Network
The primary purpose of computer networks is to transfer data from a source machine to a destination machine. One of the elementary ways to transfer data between machines is to use removable storage media. The steps for the transfer are −
- Copy data from the source computer to the removable storage device.
- Physically transport the removable device to the source computer.
- Copy data from the removable device to the destination computer.
Some of the removable media that can use for transferring data between devices are −
- Magnetic tapes
- Optical discs like CDs, DVDs, and Blu-ray Discs
- USB flash drives
- Zip discs and floppy discs
- Memory cards and Memory sticks
Advantages of data transfer by removable media are −
- They assure high bandwidth. The amount of data that can be transferred is as large as the capacity of the storage device.
- They provide better data security.
- The cost per bit of data transfer is typically very low.
Disadvantages of data transfer by removable media are −
- This is a crude method. Though data transfer occurs, no actual computer networks are set up.
- The speed of communication is very low. The time taken for the transfer can range from several minutes to months depending upon the distance and the physical transportation facilities between the source and the destination devices.
- Data transfer is greatly inhibited by the incompatibility of the removable media with the communicating devices. For example, it is not feasible to transfer data from a computer to a smartphone using a DVD.
- Broadcasting data is almost impossible.
