Step 1
Explain Network
Answer
A network is a collection of computers, printers, and other equipment that are connected together to facilitate communication. This connection can be established through wired means, such as special cables, or wirelessly, using radio waves. The primary purpose of a network is to allow data and resources to be shared among multiple users. This includes sharing files, accessing shared printers, and even allowing users to communicate through various methods like email or instant messaging.
Step 2
Explain DVD-R
Answer
A DVD-R (Digital Versatile Disc Recordable) is a type of optical disc used for storing data. It has a potential storage capacity of up to 8 GB, making it suitable for holding full-length movies or large data files. The key feature of a DVD-R is that it can only be written once; once data is written to a DVD-R, it cannot be altered or erased. This characteristic makes it different from a DVD-RW, which can be rewritten multiple times. To access the data on a DVD-R, a compatible DVD player or drive is required.
