What does computer storage capacity relate to?

The storage capacity of a computer is related to "bytes". Bytes are a unit of measurement for measuring the storage capacity of computer memory. The storage capacity of a computer refers to the amount of binary information that the memory can hold, that is, the number of bytes; one byte stores an 8-bit unsigned number, and the stored value range is 0-255. Just like characters, byte type variables only One byte (8 bits) of memory space is required for storage.

The storage capacity of a computer is related to "bytes".

Bytes are the basic unit of measurement for computer memory storage capacity.

The storage capacity of a computer refers to the amount of binary information that the memory can hold, that is, the number of bytes. It is expressed by the product of the addressing number of the storage address register MAR in the memory and the number of words stored.

One byte stores an 8-bit unsigned number, and the stored value range is 0-255. Like characters, byte type variables only require one byte (8 bits) of memory space to store.

Storage capacity refers to the maximum amount of data that the portable storage product can store, and is the most critical parameter of the portable storage product. Generally, the capacities of U disks include 1GB, 2GB, 4GB, 8GB, 16GB, 32GB, and 64GB. There are also some products with higher capacity, but the price has exceeded the level that users can accept. Among them, 1GB~2GB portable storage has been basically eliminated by the market; while 4GB~16GB products are the mainstream in the market, with prices within the acceptable range of ordinary users, and they are also the capacity type with the most product types launched by manufacturers; products above 32GB , because the price is expensive, the user group is small, and the product types are also small.

Unit conversion

As the amount of stored information increases, there are larger units representing storage capacity units, such as gigabytes (GB, gigabyte) Higher ones include: terabyte (TB, terabyte), PB (Petabyte), EB (Exabyte), ZB (Zettabyte) and YB (yottabyte), etc., among which, 1PB=1024TB, 1EB=1024PB, 1ZB=1024EB, 1YB=1024ZB. So, what exactly are the capacities of these units? Please take a look at the representation: Ki1obyte(KB)=1024B is equivalent to the content of a short story.

• Megabyte(MB)=1024KB

• Gigabyte(GB)=1024MB

• Terabyte( TB)=1024GB

• Petabyte(PB)=1024TB

• Exabyte (EB)=1024PB

• Zettabyte(ZB)=1024EB

• ##Yottabyte(YB)=1024ZB

##Extended knowledge: database avoids waste of storage capacity

One of the manifestations of massive waste of database storage capacity is data redundancy, which refers to a field that appears repeatedly in multiple tables. For example, if every piece of information about a customer purchasing goods is also recorded with the customer's own information, such data redundancy may cause inconsistencies because the customer's own information may be different. Data redundancy can lead to data anomalies and corruption and should generally be avoided by design. Database normalization prevents redundancy and does not waste storage capacity. Appropriate use of foreign keys can minimize data redundancy and anomalies. However, if efficiency and convenience are considered, redundant data is sometimes designed without considering the risk of data corruption.
