1) What is a PCV? What does PCV stand for? What is another name for PCV? Describe the procedure for obtaining a PCV. o PCV stands for packed cell volume. o Another name for a PCV is hematocrit. o A PCV is the measurement of the ratio of packed red cells in a known volume of whole blood sample. o The procedure is to take blood from your patient and put it into a purple top tube, which has the anticoagulant EDTA in it. • Next you need to fill 2 micro hematocrit tubes with the blood about ¾ 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…

1. My Professor’s definition of a computer is an electronic and or phonetic technological device repository of data and information with adaptive archival and retrieval methodologies. 2. D.I.K.I. is an algorithm developed and published by my Introduction to Technology professor, Doug Lauffer. The letter D is for Data, which is the numbers, words, pictures, or sounds that represent facts figures or ideas; the raw input that user have at the start of a job. The second letter I is for Information,…

P5: Set up a standalone computer system, installing hardware and software components P6: Configure a computer system to meet user needs P7: Test a computer system for functionality • In this picture you can see all the parts are missing. They were removed so that we can put it back together. • In the next picture you can see the RAM is placed in the slot. It is positioned in with small amount of force until the clips click into to place. • In the next picture we installed in the…

with being the size of 2 refrigerators. IBM invented heads that work off a cushion of air. In 1963 IBM makes the first removable hard drive with 14 inch platters and holding 2.6 Megabytes. In 1978 the idea of raid (redundant arrays of independent disks) it was then patented. (Farrance, 2006) Seagate then introduced the st-506 drive and interface, it was then used in most early microcomputer systems. The first gigabyte hard drive then comes about in 1980, costing 40,000 dollars. That is just…

1.1 Memory and its relevance to D flip flop Memory is an electronic data storage device which is usually implemented on a semiconductor based integrated circuit. The basic operations accomplished by a memory chip are READ in which the data contents of a memory is read out and WRITE in which data is stored in a memory. Each bit of information bits is stored in memory cell consisting of one or more transistors. The most basic such memory unit which stores 1 bit of data is the D flip flop. High…

write rate varies on the size of the chip some manufactures build there chips faster than others so it always best to shop around other types of memory include ROM & NOR-FLASH these types have limits and do not allow data to be wrote to them. Optical Disk…

Software testing, account testing and website testing is loaded with risks. If the worst happens, such as if a program goes rogue, if a program wrecks your hardware, if your information is stolen, and so forth, it is a good idea to have a few contingency plans. Your personal contingency plan should depend on your methods and the types of software you are testing. With that in mind, here are a few elements you may wish to enter into your contingency plans. Burnable Email Addresses The first…

Entrepreneur is a word derived from the French language meaning “to undertake”. An entrepreneur is an individual who is willing to take a financial risk to sets up a business or businesses in the hopes of making a profit. Any person can be an entrepreneur. However, a successful entrepreneur makes a good or product that people are willing to buy and is different from any other good or product out on the market. Michael Dell is an example of an entrepreneur who was willing to take a risk. Michael…

Postcode, Country Abstract Magnetic and optical disk control share a number of similarities and differences. This leads to a number of issues unique to each kind of disk. These issues and the other properties in general, of the control and servo-mechanical systems of hard disks (magnetic) and optical disks are explained in this paper. Keywords: magnetic, optical, control mechanism, servo mechanical, disk control 1. Introduction Magnetic and optical disk control share a lot of common features…
