After the first few classes of learning about C.I.S I feel that it's not as hard as it seems at first. Once we broke all the terms down and divided the sections of learning it came to be more understanding to me. Looking back at my notes (no book yet), we started off with three sections of learning which were input devices, process devices and output devices. These three sections are very important to a computer programs. These programs are a set of step by step of instructions that invovle these three sections of devices.
First, when dealing with the input devices these are some examples such as keyboard, mouse, touchscreen, scanner, microphone and digital camera etc. These devices are used to enter information into the computer. This is also where data is put into the computer and raw facts, which is also called unprocessed information. Then you might ask, how does the data get processed and that happens in the processing devices, where it accepts data from the input method used and goes through with the operation at hand at very high speeds and then displays the operations as well. The main terms used in processing devices are CPU (central processing unit), ALU (arithmetic logic unit) "doing processing"and control unit also know as the "traffic cop" over seeing everything that is going on. Along with those terms you have more terms such as memory, RAM (random access memory) and primary storage which are all self explainatory for saving and keeping data recieved from input devices. The last key thing involved with processing devices is the C-drive which is really not needed but it there for your convience to save softwares and things you have downloaded so you don't have to go through the same process (of installing) every time you turn your computer on("boots" all the other software) .
Now for the final step of all the devices which we always see is the output. The finished result after the information has been has be put into the computer and then processed. It will be put in these different symbols "<, >, = or <>" making a if , then statement letting you know all the possible outcomes. Then once this process is completed it will be put in RAM, primary storage, and memory so at your convience it wont be time consuming and easier access to using programs on your computer.
