As humans from an early age we learn to count using the base 10 system, this is a system to tell us how many times we have counted to 10 with the addition of any extra, for example the number 17 the 1 on the left shows us we have counter to 10 once and the 7 shows we have an additional 7, the number 52 shows us we have counted to the number 10 five times and an additional 2. As humans we find this base 10 system easier due to the simplicity of it, and our relation to the number 10, as we have 10 fingers which can be used as physical representations of the number. Computer systems can't use this method due to it only being able to recognized and deal with 2 states, on of off (1 and 0).

First I will explain what is analogue signal and digital signal their advantages and disadvantages and their application .then I will explain

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.

In the modern world, binary numbers have great importance in computer coding as well as in Boolean algebra Without the application of binary numbers, computers would not be able to exist or communicate with each other. Binary numbers include a base two number system rather than the base ten system which is used in a math class such as algebra. A base two system means that the only numbers that are used in that system and in binary those numbers are 1 and 0. A base ten number system beans that numbers 1, 2, 3, 4, 5, 6, 7, 8,9, and 0 are used. All numbers can be converted from decimal, the base ten set of numbers, to binary and from binary to decimal allowing computers to communicate.

     MP3 stands for MPEG 1 Layer 3 Audio, which is a digital audio compression format developed by the Moving Picture Experts Group. It takes a CD audio file and gets rid of all the frequencies on the song that can’t be heard by the human ear, thus ridding the data file of much wasted space. With compression, the files turn out to be around four times smaller than the original with the same, near CD quality audio. While “MP3“ may technically be the name of the compression format, it has become synonymous with the music files

In the hospital, a mother of 3 is found to have a pre-cancerous tumor lurking in her pancreases that could have progressed to a deadly stage if not removed promptly. Through the use of the hospital’s robotic surgical system, it was able to successfully remove the tumor allowing this mother to return home to her family. This was made possible because of the advances in computer science; Computer science is the scientific and useful way to deal with computation and its applications. The study of computer science itself studies various conditions of the use of programming languages, complex systems and artificial intelligence. Human–computer interaction considers the challenges in making computers useful, usable, and universally accessible to humans. In today’s world, as technology is rapidly perfected, society as a whole needs to incorporate the latest advances in technology that make one’s life more efficient, convenient, and useful in their everyday lives.

At primary school, I printed my first triangle on the computer monitor using QBasic. Then, at junior high school, I got familiar with VB. At such a young age, I did not know what a career was for and was just impressed by the charm of programming. Attending University, majoring in Logistics Engineering, I was delighted to know that this field did need a lot of data mining work for which I can be a programmer and made up my mind to go into this field. Thanks to the classes, internships, and research projects I’ve completed at Beijing University of Posts and Telecommunications (BUPT) over the past four years, my desire to work in this industry, and my confidence in my abilities, has only grown. However, to have a successful career in logistics data mining, further study is essential. The MS in Computer Science program at NYU would be indispensable to my professional development.

In comparison to analog circuits, digital circuits are less susceptible to noise or degradation in quality, additionally the errors are detected and corrected simply with the assistance of digital signals.

characterized by the use of digital signals to represent these signals as discrete time, discrete

Digital Computers: These are used in commerce and industry for extensive arithmetical calculations which would otherwise require enormous clerical effort. Such computers carry out mathematical operations with the variables expressed in the computer as numbers, usually in the binary system (given below).

As new technology is built and sports continue to thrive and expand on an international level, the integration between the sports world and developing technology cannot be overlooked. Although the field of sports informatics is relatively new, its development into a promising form of science is successfully emerging. The field is defined as a “collectivity of knowledge, scientific argumentation, and research methods that deal with problems and phenomena related to sport” (Lames, and Link). Given this broad definition, sport informatics possesses many attractive perspectives within sport, including but not limited to: “the measurement and reporting of physiological data, computerized performance analysis, and motor behavior and physiological adaptation” (Lames, and Link). In other words, the current approaches used by scientists in this field are described as creating a virtual environment for training specific perception tasks for a particular sport. Inevitably, this type of virtual sports environment possesses the power to redefine the athletic world as this new age of technology simultaneously redefines our culture.

1.What are the basic elements of digital signal processing. List the advantages of digital signal processing over Analog signal processing?

C++ was produced by Bjarnestroustrupstartingin 1979 at Bell Labs in Murray Hill, New Jersey, as an improvement to C dialect and initially named C with classes however later it was renamed C++ in 1983. C++is a transitional dialect , as it contains an affirmation of both abnormal state and low level dialects characteristics. C++ is a statically written, free structure, multiparadigm, incorporated universally useful dialect. C++ is an Object Oriented Programming dialect yet is not absolutely protest arranged. Its peculiarities like Friend and Virtual,violate some of extremely paramount OOPS gimmicks, rendering this dialect unworthy of being called totally Object Oriented. It is a center level dialect. C++ is a standout amongst the most prevalent programming dialects and is actualized on a wide mixture of fittings and working framework stages. As an effective execution driven programming dialect it is utilized within frameworks programming, application programming, gadget drivers, inserted software,high-execution server and customer applications, and diversion programming, for example, feature amusements. Different entites give both open source and exclusive C++compiler programming, including the Microsoft and level
