Each type of memory is more useful to specific applications. Semiconductor memories are the preferred choice for portable electronics, optical storage is mostly used for movies, software and gaming, while magnetic data storage remains the dominant technology for high-capacity information storage, including personal computers and data servers.

In binary code, the digital information is stored as ones and zeroes, also known as bits. Eight bits form a byte. A logical zero or one is allocated to each physical state. The smaller these physical states are, the more bits can be packed in the storage device.
The width of digital bits today is around ten to 30 nanometres billionths of a metre. The cloud has undoubtedly transformed the speed and ease of which we are able to work and collaborate, particularly across devices and different locations—but it is not without risks. Cloud solutions come in many shapes and sizes - so if you are not sure which one to go with, ask an IT expert.

There are a couple of commercial changes coming to Microsoft that you need to be aware of and prepare early for.
Servers store and process data just like a computer, and are connected to the Internet through wired or wireless connections. A data center is made up of numerous data servers housed in the same complex. Like computers, servers require certain environmental conditions, such as moderate levels of heat and humidity, as well as network connections to access the Internet.
Large data centers with huge amounts of hard disk storage allow the companies that operate them to capitalize on economies of scale, saving more data for similar costs on site maintenance and connectivity infrastructure. Many large Internet companies operate their own dedicated data centers, while some data centers offer storage services for multiple clients. Just like two computers connected in a local network, Internet servers send information to Web browsers through network connections.
Each byte is comprised of eight bits of data. Each bit can either be a zero or a one. The byte system allows what humans read as words or numbers, as well as logical processes within computer applications, to be transferred from one place to another in binary.
Binary is a language entirely comprised of ones and zeros. One represents true and zero represents false. A computer at its base level reads these ones and zeros and can execute any function it is told to do. Essentially, binary acts as a set of instructions for the computer to follow. While all of this does not sound complicated, things become complex when a computer must account for billions of bytes.
Does this sound unrealistic? The average file size today is around 3 Megabytes, which converts to three million bytes of data. Thankfully, with modern technology, a file transfer of this size can be done in mere seconds.
