What is a Terabyte

Terabyte is a term used to refer to a specific unit of computer memory. The term terabyte is primarily a data storage capacity that equals to 1,024 gigabytes or one trillion bytes. Terabyte is mainly a multiple for the unit of byte for digital information. One unit of terabyte is 0.9095 tebibytes or 931.32 gibibytes. Hard disk drives assume immense importance to computer systems simply because of the fact that they store data, programs as well as files. Average computer systems boasts of single hard drive and holds a capacity of 20 megabytes. The average capacity of hard drives increased to nearly eighty MBs in the mid 1990s.

There is no real doubt about the fact that storage has become an important aspect since there has been an advent of music files, home studios, photo programs and graphic. The importance of storage is similar to that of real estate. Over the years, there has been a dramatic decrease in the cost of hard disks and continues its downward trend. It has been perceived that most people are gradually becoming a lot inclined to install Redundant Array of Independent Disks. A RAID can be termed as a continuous series of hard disks that operates as a single storage unit.

Terabyte-Preliminary Concept

It is a heartening fact that the RAID array holds the capability to surpass the one terabyte threshold. The basic idea of the concept of terabyte is highlighted below:

• 1, 024 megabytes= 1 gigabyte
• 1,024 gigabytes=1 terabyte
• 1,048,576 equals to one (1) terabyte

Concept of Terabyte Used in Various Fields

Terabyte is used to describe data sizes in different fields including computer hardware, audio, Encyclopedia, usenet messages, library data, climate science as well as social networks. Terabyte is widely used in the field of audio. Audio recorded at circular disc quality will contain 2,000 hours of audio. Terabyte was also used to describe data sizes in the field of historical internet traffic. Total internet traffic amount to nearly 100 terabyte in the late year 1993. One of the other highlights projected was that the amount of internet used in the year 2008 surpassed the entire internet usage for the year 1993. Terabyte used in the video field released in the year 2009 used 100 TB storages during the development phase.

One must have gained an idea about the fact that terabyte mainly focuses on huge amount of data. Petabyte signifies even larger amount of data. Petabyte accounts for as many as 1,024 terabytes. The benefits one can possibly gain with a terabyte external hard drive is simply immense. If in the case, one requires more storage space then it is necessary to consider internal terabyte hard drives that one can install right into the cpu.
