114. If new software requires more memory space on computers, how many terabytes will an average user need to working online in twenty years?
Here I would like explain at first about terabytes. Terabytes defines a unit of information equal to one million million (1012) or, strictly, 240 bytes). Terabytes are most often used to measure the storage capacity of large storage devices. While hard drives were measured in gigabytes for many years, around 2007, consumer hard drives reached a capacity of one terabyte. Terabytes are also used to measure bandwidth, or data transferred in a specific amount of time.
Before buying a computer or laptop u need to think about how much you need. It is better you buy such things according to your needs. For example if your computer for convenience- light , internet browsing, watching you tube, writing document , then you are fine with 2 GB of RAM. But if you run multiple programs at once and keep dozens of browser windows open at once , you might want 4 to 6 GB of RAM installed.
20 year ago people are not very familiar with digital devices and use limited apps. In that time normal people use 2 GB of RAM as they do not have many things to do with technology.
