GIVE TWO TYPES OF STORAGE DEVICES USED IN A COMPUTER GIVING AN EXAMPLE OF EACH.
There are various categories under which storage devices can be classified;
a) CLASSIFICATION OF STORAGE DEVICES BASED ON THE DURATION OF TIME THEY STORE INFORMATION.
Storage devices in this category can either be;
b) classification of storage devices based on mobility.
Storage devices can also be categorized according to mobility. I.e.
c) classification of storage device on how they function.
Storage devices functions in different ways depending on the technology used to manufacture each one of them. They include;
previously: A SPREADSHEET HAS THE FOLLOWING ENTRIES. PROVIDE A FORMULA FOR CELL C5 THAT CAN BE COPIED ONTO CELL D5 AND THE RANGE C6...D10 TO GIVE A UNIFORM INCREASE OF 10% OF THE PREVIOUS YEARS VALUE FOR EACH ITEM.
This is the ability for a computer to accept data either through input devices such as scanners, keyboards, mice and others or through information retrieved from storage devices.
Input of data is a main function because all other functions depend on the incoming data for processing and output.
Processing and storage are sometimes broken down as separate basic functions of a computer. However, looking at this critical idea keenly, we notice that processing and storage are sometimes inseparable this is because processing devices rely heavily on storage devices vis a vis.
Processing is an act where a computer converts raw meaningless piece of information called data into a more meaningful piece of information.
This is normally done with a closer help of primary storage devices such as the RAM, and special types of memories such as the registers, buffers and cache memory.
Processing is a main function of a computer because of the conversion, manipulation of numeric data and logical decisions.
This is an act for a computer to display the result of a processing activity. This can be done using output devices such as the monitor, printer, plotter, speakers etc.
The functions of a computer system cannot be complete without the output, simply because it gives a feedback of the result for the computer user to digest, change, amend, store or print.
