What is the safest way to store data?

5 Ways to Back up Your DataKeep It in the Cloud.Save It to an External Hard Drive.Burn It to a CD, DVD, or Blu-Ray Disc.Put It on a USB Flash Drive.Save It to a NAS Device.

Which is the smallest storage?

Bits are the basic building blocks of not only data storage, but all computers. Computers work in binary digits, combining 0’s and 1’s in countless patterns. These binary digits are known as bits, and are the smallest possible unit for data storage. When 8 bits are combined, you get a byte.

What is the cheapest storage device?

Hard drives probably come next. Significantly cheaper than flash, a hard drive provides fast random access to large volumes of data. Hard drives fail under many conditions, so redundancy and backups are probably necessary. Lifetime of a hard drive is less than a decade, often much less.

Which memory is needed to execute the program?

Answer: The programs and data that the CPU requires during execution of a program are stored in this memory. It is a volatile memory as the data loses when the power is turned off. RAM is further classified into two types- SRAM (Static Random Access Memory) and DRAM (Dynamic Random Access Memory).
