Exercise Nr 1: 1) Data Storage






The Data Storage feature is the set of specifications used to define how, when and what is stored. In any organization , regardless of industry or size, it can be seen that data is growing at an exponential rate and that creates a problem when storing. It is no longer enough to store, but you have to define a strategy that provides the basis of storage. Better explained, Data Storage is a capacity of store. The Data Storage can’t be virtual because it’s more safe physically. Data Storage contains all the information that one posts on the Cloud. If one loses information, this one resolves it by giving it back. Data Storage function seeks to implement good practices and policies that meet the objectives set from the Data Governance , so that no alignment is lost. A graphic example would be to compare the management of food to keep in the pantry of a house with food to store in a supermarket. While in the first case the volume is so manageable that does not require an order in the second , the logical order is essential.
The IBM 350 was the first disc drive introduced by IBM. It had a Data Storage capacity of about 3.75 MB and was available on lease $3200 per month.
Examples: discs, CD, RAM, DVDs, Storage Tapes, Memory carts, Floppy disks, etc…

What is meant by data storage? By Lisette Habig and Astrid Corbacho


Data storage


“Data storage” is a name for storing a data on the computer.You can store any kind of information. (That could be music, videos, audios, documents, pictures, emails...) This information is considered memory and the components that store it are termed primary storage.

  • Primary storage: The place where you can store memory on the computer. This data is is stored inside the computer. Most of the time the primary storage is the RAM. The word RAM means nothing else than RANDOM ACCESS MEMORY and it is a type of Computer memory. It is also the most typical type of memory used on computers, and other devices. There are two types of RAM:
  • -DRAM: DYNAMIC RANDOM ACCESS MEMORY
  • -SRAM: STATIC RANDOM ACCESS MEMORY
       These two types of RAM differ in the technology they use to hold
        data. DRAM is the more common type. SRAM is faster.
  • Secondary storage: Here you can store the memory on a hard disc in devices like: CD-ROOM DISK, USB, Flash memory sticks,...This memory is stored in devices outside the computer and you can insert them and pull them out.

There are a lot of storage devices. Can we create a hierarchy or a timeline? By Lisette Habig and Astrid Corbacho
