Question 1:The question we muststudy, if the network computers and thin clients may substitute the personalcomputer, cannot be answered in an absolute way but is depended from the user’sneeds. More specifically, probably teenagers have different needs than a professionalin banking or insurance sector. Therefore, we should analyze the strengths and weaknessesof each solution. So, we have to make a research on it and after that we canget a view on the subject.Network computersgives us the benefits to easily share resources, to exchange data between the clientsfrom the central server and users to updated the newest versions of theapplications. Furthermore, all users can be updated between them with decreasedthe probability to have communication lag or misleading information and theyearned time and money.
However, If the server stops running or the networkpresents a problem, the data stops being shared, and the user must communicatewith the person who is responsible for the server maintenance. Moreover, thismeans that all clients are depended to this person. If a user is naive and caneasily become a hacker’s target, it may become dangerous for the users who shareacross the network and the central server.Thin Clients are low-cost computing device which are managed by a central server and are not easilyaccessible and vulnerable to attacks and use less power.
Personal computersintended for individual use. This typeof computer, is designed for use by only one person and there is no needed anycommunication with other systems or users. Each of those users probably havetheir own needs and they also have the ability to design the applications andprograms they are needed. Probably Personal Computers have high initial cost andare costly also for the updates. I suppose that theanswer of the initial question for the future of personal computer is acombination of the classic – old school – personal computer with the services andadvantages which offered a network solution.
In my opinion, “home”users willcontinue to buy a personal computer for their individual usage, with theirindividual needs and application but they will have the choice to be connectedto a network or cloud only for specific purposes as exchange information or touse a specific program with some limitations (time or versions). User couldchoose how deep will be this connectivity with other users or to the central server.Thin clients could not substitute the personal Computers in this connectivitybecause are not a complete solution. Question 2:a) The data of Fortune magazine are collected via a questionnairesurvey that is answered by randomly selected employees of companies. Fortune magazinepreidentified some factors which probably effect to the people selection forwhich company they prefer to work.
The results of these questions generate thedataset with categorial variables. Also, the results are the source of anIndex, the “Trust Index” which measure this argument. Each question has aselection scale of min to max or lower to more because the Surveys resultsshould be measurable(quantitative). The questions have varied subjects ortargets, for example some are for the Company’s environment, the Colleaguesrelationship or the motivation skills of the leaders of the Company.
Variablesas the average salary, total number of Full Time employees, the percentage rateof women at a Company, sector of Economy etc.b) By analyzing the data which collected from the Questionnaire,we can identify which factor the employees believe is more important for theirchoice and for which company they want to be a part of. On the other side, IfEmployers study this data will improve themselves and their companies and theycould have more efficient, productive and satisfied employees.
c) Wrong results and low ranking probably to denigrate acompany. Also, wrong results the Fortune magazine could lose the trust from itsreaders and accuracy of the “Trust Index”. Question 3:Radio-frequency-Identification,common RFID uses electromagnetic fields to automatically identify and tracktags (or smart labels) attached to objects using radio waves. RFID systems dividedby 3 parts, an RFID tag or smart label, an RFID reader, and an antenna. RFIDtags used a silicon microchip to store a unique serial number and some otherinformation. RFID includes two types of systems.
The passive and the active. Thedifferences between these two types, passives do not include transmitter andjust take power source from the reader’s antenna. Active include a transmitter andtake power source usually from sun. Passive RFID tags usually tags at items ina store which needed to track the movement. Active RFID tags often atContainers or other big assets which needed to be tracked from long distance,at checkpoint control. RFID antennas collect the waves which sent from RFIFtags. RFID technology willhave many effect at the retail market. If the RFID tags replace the classicBarcodes is possible to collect data of the Items movement in the store and theBI team if analyze this information will identified which place in the store ismore productive.
The replenishment procedure would be easily and less timing,because when a product moved from a shelf, a sign would send to a Warehouse.The Classic POS would improve to an intangible procedure with online paymentsprobably with a mobile app. Stocktake procedure could be easily and fastest withhand antennas which could count the stock. The companies canprovide information and to ensure that their products are in the place theyshould be. To be able to say that this has a positive effect, it should thereare fewer products that are discarded and not consumed. In this way employerscontrol both products and people as employees.
Question 4:a) Voice or speech recognition at simplewords is the ability of a machine or program to receive and recognize human linguisticsinstructions and execute specific commands. Your speech provides vibrations in the air. Adigital converter (ADC) translate those vibrations to digital data.
This data isrecognized only by the computer. The machine/program filter this sounds andremove unwanted voices. Also, adjust the volume of the sound so the finaltranslated voice is clear and at a normal level. People speak to a differentlevels and volumes. So, the program edit and then match this speech to a predefinedtemplate sound samples that are already in the system. After that the Voice Recognitionapplication take the
