Often the capacity of the storage becomes a point of concern and is considered as one of the main points while considering the worth of a computer system. The storage of the computer system can be used to tell you the amount of data that can be handled by the system at a certain point in time. It is, however, true that there are different types of storage available in the computer and each one is associated with a different job. PC Storage would often be used to refer to the secondary storage of a computer, though it is not what is quite essential to the working of the computer. Large storage capabilities can help the computer to store and use large amounts of data, but the cost of processing in terms of time and money would be higher.
PC Storage, the technology to retain digital data, is a core function of the computers. The computer systems would always have a storage hierarchy. The CPU or the central processing unit is responsible for managing the storages by performing computations and storing the data in these storage locations. The smaller and faster storage systems are located closer to the CPU and are generally more expensive, while the larger ones are cheaper and are located farther away. The faster technologies are generally volatile and sometimes referred to as the 'memory', while the slower technologies can be referred to as 'storage'. This is also because these faster storage locations can offer to store or hold small amounts of data, but the slower systems can retain large amounts of data.
Without the computer storage, the computer would be able to perform only a few basic operations and output the result immediately. The primary storage is the main memory of the system and this is where the data that is directly accessed by the CPU is stored. The Random Access Memory or RAM is small in size but is quite expensive at the same time. But the system is also volatile. Processor registers located in the CPU can help to store a few bits or words of data. The cache, on the other hand, is a very fast memory that can help to store data for short periods of time to increase processing speeds.
The secondary storage devices help to store large volumes of data. Hard disk drives are one of the most common examples that are used today. There is a huge difference in the time that is required to access the data from the primary storage than it is the case with secondary storage. The Tertiary storage is also available to computer systems but it is not very common. With the hierarchy of computer storage working in proper order, the computer systems can function effectively.
