Magnetic Tapes and Magnetic Disks are the types of magnetic memory.

A digital wallet is a software-based system for making e-commerce transactions. By using a digital wallet, online purchases can be done easily through computers, tablets or smartphones. In general, bank accounts of individual users are linked with their digital wallet.

Storage Systems

Magnetic disks are coated with a magnetic material such as iron oxide. There are two types: hard disks made of rigid aluminum or glass, and removable diskettes made of flexible plastic. In the first magnetic hard drive HD was invented at…. Magnetic disks are platters coated with iron oxide, like tape and drums. This invention led not only to more cleverly designed file systems but also to the development of database and information retrieval systems, which later became essential for storing, retrieving,….

Advanced Database Indexing pp Cite as. A storage hierarchy made up of levels, as shown in Figure 1. A general remark about the memories in this hierarchy is that, when descending from top to bottom, the memories become slower, larger and cheaper. In general, storage devices can be divided into three categories: primary, secondary and tertiary storage. The upper two levels of this hierarchy are characterized as primary storage. The next two levels are characterized as secondary storage, while the last level as tertiary storage.

Disadvantages: Needs serial access, so can be quite slow to access data. This disk was the high speed of access and update as no sorting of transactions. This disk was the high speed of access and update as no sorting of transactions Disadvantages of a magnetic disk: Expensive than magnetic tapes. A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data. This technology has many advantages, as well as some disadvantages, which is why in , many types of magnetic storage have given way to some newer and more improved technologies. Advantages of optical disk compare to magnetic disk: The storage capacity of the optical disk is more than a magnetic disk.
