Computer data storage

Data, information, knowledge and wisdom are referred to as the DIKW hierarchy model cited in Figure 1. This visual metaphor illustrates large amounts of data at the bottom of the pyramid which are reduced to smaller amounts of information consequently creating more condensed knowledge and even smaller wisdom. For Ackoff (1989) data is a symbol and does not have meaning on its own. Information emerges from data that has been processed and hence data has now been given meaning. Knowledge is built…

created a monster or become one. In the late spring of this year, my sister brought home an honest ex-marine, carpenter, and computer genius, or so I thought. We spoke of endless topics over an old-fashioned game of horseshoes. Days became weeks and weeks became months as his silhouette of lies unraveled. After five months of lounging around, he…

1. The advantage of using a very large memory cell size is that the computer can store larger values in its memory cells. The disadvantage is that there would be fewer cells available. 2. This question asks how many bits are needed in the MAR with the following numbers a. 1 million bytes = 20 bits b. 10 million bytes = 24 bits c. 100 million bytes = 27 bits d. 1 billion bytes = 30 bits 3. 640 kb would be 655,360 memory cells. A 512MB would contain 536,870,912 memory cells. A 2GB would contain…

The DE2-115 peripherals lab results were quite interesting, both numerically and visually. In part one of the lab, the results pertained to the largest number a bus could hold. For example, it was calculated that a bus of [17:0] could hold any number up to the limit of 262143 using the equation (1). Also, when the value of X in Figure 5 was changed a certain number of lights would begin to blink on the LEDs above the switches. As the value of X increased the number of the switch that would…

THE cache memory is a quick and small and, in layman's terms, it is basically a middleman between the processor and main memory. Caches are used so that you do not have to go all the way back to the main memory if you do not have to. Think about it, this process is not something that is new to us. We used this exact same method in junior high and high school, comparatively lockers are main memory and cache memory is a book bag. Instead of always having to go to a locker after every class a…

Question 3: a) What is the main use of stepper motors? In essence, stepper motors are applied in motion-control positioning system. For instance in 3D printers, disk drives, intelligent lighting, scanners, CNC machines, printers, camera lenses, plotters and slot machines. b) What are the similarities and differences between a reluctance, a permanent magnet and hybrid stepper motors? The three motors are similar in that, they all have power electronic control that comes with electronic…
