Data Discussion Paper
This paper will cover many aspects of data as it applies to computer usage, storage, performance, input, and output devices. First, I will discuss methods of data input and which would be best for various situations. Then, I will talk about methods of output and which devices would work best in several different situations keeping in mind that convenience and quality are very important in output devices. I will then cover different types of storage devices and which ones are more effective in certain scenarios. The final portion of this paper will explain the role of many different aspects of a computer which determine the computer’s speed.

Where the paper basically describes the possible similarities between the sequences. While summarizing the paper she explained the run index and diagonal index. Here run index is when we are considering every consecutive diagonal and principal index is when we are taking only the principal diagonal. While explaining the examples many questions has been arousing, David and Jafar make a quite discussion over Table 1 and Figure 1, a question arose why this paper is comparing with these another cytochrome (while compa...   [tags: Amino acid, Protein, DNA, Acid]

Briefing Paper based on Vaks et. at.

- The past climatic history of Siberia has been explored through dating of speleothem samples from caves (Vaks et al., 2013). Speleothems are cave carbonates such as stalactites and stalagmites (see fig.1), which form when calcium carbonate is deposited into a solid from a solution, a process called ‘precipitation’ (Bradley, 2015). Cave conditions are unlikely to be affected by daily or seasonal variances in temperatures therefore through studying speleothems, the climate conditions throughout the past can be inferred and this paper seeks to put forward several predictions for the future....   [tags: climate, speleothems, permafrost, carbon release]

Critique of Data Analysis Essay example

- This paper addresses a currently relevant topic of detection of associations of copy number polymorphism with traits and will be of interest to readers of Genetics Research. The simulation study showed that the additional information of CNP could increase the accuracy of predicted genotypic value, compared to using SNP information alone in an association study. The accuracy was heavily dependent on the heritability of CNP phenotypes (correlation of CNP genotype and phenotype) (Table 3). The higher accuracy of the prediction with CNP information might also result in smaller mean squared errors of prediction (Table 4)’....   [tags: Genetics]

A printed questionnaire may be inputted into a computer in several different ways: the information could be hand typed in using a keyboard, or scanned using an optical data reader. It is probably more efficient to use an optical data reader to scan in a questionnaire. A telephone survey would be highly effective if you used a voice recognition device to directly input the information received into a computer for processing and organizing. Bank checks are more than likely to use a magnetic ink character recognition input device which would be fast and accurate for inputting bank check data. Retail tags would probably use a barcode scanner to efficiently input data into the computers for processing. Long documents, while able to be typed in using a keyboard, are better suited for an optical data reader (scanner). If the right software is available, your long documents can be scanned in and converted to text which can then be edited.
Output Methods
There are a lot of different output methods for data, photos, documents, and presentations. The most important aspect of data output is quality and, depending on the situation you are faced with, one output device may be more effective than another output device. If you have a handheld computer the best output device would most likely be a LCD screen which can give you a clear liquid crystal display for your viewing pleasure. A color photograph has several options for output. You could use a high quality printer to make a hard copy of your photograph, but an organic light emitting diode might give you a higher quality display of your photograph. A standard resume or even a memorandum would probably be best suited for a standard inkjet printer for output. One could make many copies of a resume or memorandum which would all look exactly the same and could be used many times. A statistical report or a company annual report have several options for output as well, it would certainly depend on the situation and what was called for. If giving a presentation, an overhead projector or a display monitor would be the best output devices for a statistical report or a company annual report. A printer would also be an effective output device for a statistical report or a company annual report.
Storage Devices
There are many different types of storage devices available to the everyday computer user and one device may be better suited than another device, depending on the situation at hand. A hard disk would probably be used for an upgraded inventory control system, as it can store a massive amount of data which can be recalled relatively quickly. A floppy disk, although practically obsolete at this point, could be used to store data and information which could easily be stored and transported. RAM only temporarily stores data, yet is vital for the operation of your computer. A CD ROM is a good way to store a lot of data. CD ROM’s a very popular way of storing music, photos, documents, and data. Magnetic tape, in my opinion, is a great way to back up disk drives and keep offsite in case something bad happens to your original information systems. A flash/jump drive is a very easy way to store and transport data in any form. Students and professionals alike could utilize flash/jump drives easy portability and potential to store and transport data.
The Speed of a Computer
There are many different aspects that play various roles in determining the speed of a computer. RAM, random access memory, plays a very important role in the speed of a computer. RAM is temporary data storage your computer uses to execute the various programs you are running at any given time on your computer. The more RAM you have, the faster your computer could be. Clock speed basically determines your machine cycle time. Faster clock speed directly affects the speed at which each instruction can be executed. Data on hard disk gives direct access to stored data which can be recalled directly and quickly in most cases. Programs, like Adobe Photoshop, can also use your hard disk as a means to running the program faster by accessing some of the space on the hard disk while in operation mode. Data on a CD ROM can hold almost 500 times more information than that of a floppy disk. Since CD ROM’s are read only, you can record info once and easily and quickly access it at any time.
I have discussed many aspects of data as it applies to computer usage, storage, performance, input, and output devices. I covered methods of data input, data output, different types of storage devices, and I explained the role of different aspects of a computer which determine the speed of a computer. It is clear that there are many options for general computer usage. The more you know about different devices, the better chance you will have in determining which device to use in any given situation.
