Importance of Mastering Computer Skills in the 21st Century Essay

Importance of Mastering Computer Skills in the 21st Century - Essay Example Even the most basic computer skills are incredibly important, and there are many tasks that would be considered as being the 'basic' computer literacy skills, and they are: performing basic operations, such as turning the computer on and off, which sounds simple but which can actually be rather tricky to people who have never used a computer before; word-processing, as this is considered as being the most basic of all skills because when using computers it is easier as the computer deviates it a little from the common typewriter; email, which is obviously incredibly important to learn because this is considered as being the modern-day form of mail, and these days most all communication is done through email; printing of a document, which although not always necessary is crucial to learn; and finally the use of peripherals, as you need to be able to know what a portable driver is, for instance, and how it is used. Once you have learned even just the most basic computer skills, then you will be able to move forward and start learning and understanding about the multitude of other issues that there are for you to grasp the concept of, and although things may often seem a bit difficult to start off with, if you begin by learning the basic steps you will see how much dramatically easier the entire process is overall. There are many consequences that are sure to come if you do not have computer skills, for instance you really cannot get a good job these days if you do not have computer skills, not only because most companies and businesses require you to do some sort of computer work, but as well because you are going to have to know how to type up a resume and cover letter on the computer and print it out, as well as respond via email to possible employers. You are certainly going to have a lot of trouble if you do not have computer skills under your belt, which is why you most definitely should make sure that you take some sort of class or go to some type of seminar where you can learn the essential computer basics, and you will immediately notice the benefits that you will reap from doing so. In the 21st century, a large majority of work and communication is done using computers, and especially in regards to the Internet, which, if you learn how to use properly, will allow you to go places that you never thought possible. For instance, there are so many different types of jobs and working opportunities that you can find on the Internet, and for the most part, these will be options that you would not have otherwise had, without the use of the Internet. Not only that, but rather than using postage mail as had been more largely used in the past, with the Internet you are able to connect and communicate with people all over the world, whether they be friends, family members, or people you just met, quickly and easily. There are so many different benefits that can come from you having even the most basic computer skills, which is why it is truly so important to keep up with the times and make sure that you are aware of the advanced technology, in particular computers and the I nternet.

Geiger counter and its control unit - Lab Report Example The behavior is illustrated inform of a curve of pulse height against applied voltage. Using the count rate C1 (beginning of the plateau) and the count rate C2 (almost 100 to 10 volts beyond C1). Both count rates were allocated operating voltages V1 and V2 respectively. The values of V and C were used to determine the slope of the plateau using an equation. Once the system is set up in an optimum condition, source 1 is placed on the split holder and the number of count rates per second is measured as N1. While the source is still in place, source 2 is placed in the holder and the equivalent count rate per second taken, as N12. Source 1 is now removed and the number of count rates per second is taken as N2. Finally, this can be used to calculate the dead time. The slope and the percentage slope of the curve can also be worked out from the count rates. The period of time, during and immediately following an ionization event, when the system is insensitive to a further radiation, is referred to as the Dead time. After placing the material in the holder and setting the voltage to a certain value, we stills didn’t record any count rate until we attained a certain value of EHT. This is because the energy is very low below that point to be able to separate them very fast. On the other hand, the behavior of the system depended on magnitude of the potential difference applied between the anode and the cathode. Radioactive material can be used to determine the operating voltage of the Geiger counter, the slope percentage of the plateau and the dead time of the counter. This simply involves radioactive material and recording its EHT and counts rate at a certain amount of time. The count measure occurs due to the radiation released and emitted by the material in the holder. When a specimen or material is in exited state, it means that it has absorbed
