DEVELOPMENT OF COMPUTERS OVER THE DECADES
A Computer is an electronic device that can receive a set of instructions, or program, and then carry out this program by performing calculations on numerical data or by compiling and correlating other forms of information.
The modern world of high technology could not have come about except for the development of the computer. Different types and sizes of computers find uses throughout society in the storage and handling of data, from secret governmental files to banking transactions to private household accounts. Computers have opened up a new era in manufacturing through the techniques of automation, and they have enhanced modern communication systems. They are essential tools in almost every field of research and applied technology, from constructing models of the universe to producing tomorrow's weather reports, and their use has in itself opened up new areas of conjecture. Database services and computer networks make available a great variety of information sources. The same advanced techniques also make possible invasions of privacy and of restricted information sources, but computer crime has become one of the many risks that society must face if it would enjoy the benefits of modern technology. (Gulliver 12-15)
Imagine a world without computers. That would mean no proper means of communicating, no Internet, no video games. Life would be extremely difficult. Adults would have to store all their office work paper and therefore take up an entire room. Teenagers would have to submit course-works and projects hand-written. All graphs and diagrams would have to be drawn neatly and carefully. Youngsters would never have heard of 'video-games' and will have to spend their free time either reading or playing outside with friends. But thanks to British mathematicians, Augusta Ada Byron and Charles Babbage, our lives are made a lot easier. (Malone 5-6)
There are two main types of computers that are in use today, analog and digital computers, although the term computer is often used to mean only the digital type. Analog computers exploit the mathematical similarity between physical interrelationships in certain problems, and employ electronic or hydraulic circuits to simulate the physical problem. Digital computers solve problems by performing sums and by dealing with each number digit by digit. (Cringley 28-30)
Hybrid computers are those that contain elements of both analog and digital computers. They are usually used for problems in which large numbers of complex equations, known as time integrals, are to be computed.
The baby’s health is a main concern and in order to keep him or her healthy, mothers should breastfeed. Heather M. Kolinsky’s research proves that babies who are breastfed for at least the first six months of birth are “less likely to contract a wide range of infectious diseases.” The reason for this is because breast milk is made distinctly for the child. There are specific nutrients provided in breast milk
The good news is that mothers can eat anything they want without causing upset stomach in their breastfed babies. Although some foods such as cabbage, broccoli, spices and garlic are known to be gas formers in the mother's digestive system, these foods will not affect the milk they produce.
Breastfeeding is when a woman feeds her child from her breast. Breastfeeding has been around since before the 15th century. In addition to strengthening the bond between a mother and her baby, breastfeeding offers a number of benefits for both a mother and her child. Babies who are breastfed have lower risk of meningitis, various cancers, diabetes, respiratory illnesses, bacterial and viral infections, childhood leukemia, allergies and obesity. Mothers have a reduced risk of breast and ovarian cancer, as well as osteoporosis. All mothers no matter where they are weather it be the mall, park, restaurant, or just out running errands need to have their right to breastfeed protected.
Breastfeeding is the most protective, nutritional, and natural way to provide nourishment to infants. Human milk contains several nutrients including: vitamins, proteins, lipids, carbohydrates and minerals. These nutrients are imperative for an infant’s developmental growth. Human milk also reduces the risk of developing morbidities, especially within premature infants. Premature infants, who are more prone to infection due their immune systems, benefit from human milk. Compared to artificial formulas, human milk provides antibodies and other beneficial nutrients to help with the development of the infant.
Breastfeeding has many benefits to baby.1 Babies who nurse beyond 6 months of age see these benefits magnified.1 Babies that breastfeed see a decrease in morbidity and mortality rates as well as an improvement to overall health. 1 According to the American Dietetic Association, evidence shows that babies who are breastfed have a reduced risk of chronic and acute diseased.1 Some health benefits of breastfeeding include a reduced risk of the following: otitismedia, gastroenteritis, respiratory illness, sudden infant death syndrome, necrotizing enterocolitis, obesity, and hypertension.1 Babies t...
...repercussions throughout life such as allergies and autoimmunity. This is considered to be one of the paramount advantages breast milk possesses because, it is exclusive to mother’s breast milk and duplication of these factors in formula or animal milk is at this present time unattainable.
Breast milk is the effective way of ensuring child health, Breast feeding is widely accepted as a optimal feeding for the infants due to health benefits it offers to the child. Lack of breast feeding contributes to one millions of death each year globally.1A study conducted in U.S.A revealed that breast feeding can cut cost of government and saves 3.6 billion $ and also saves the lives of infants. 2Breastfeeding helps to reduce the infant mortality and morbidity especially during the first year of life. 3Neonatal mortality can be reduced by 16.3% if breastfeeding is initiated on the first day and by 23.3% if initiated with in one hour. Breastfeeding promotion is an essential component of child survival strategies. Lancet neonatal survival series included breastfeeding in its recommended package to reduce neonatal mortality. The World Health Organization Collaborative Study Team reported that infants breastfed for 2 months show high protection when compared with later ages. 4
Although there are many reasons to promote breastfeeding during early month of life, it is effectively in preventing food allergy in infant. A mother’s diet during pregnancy does not cause food allergy in her infant. Most studies show the maternal diet during pregnancy has little influence on sensitization on the infant to foods (Kjellman, NIM., Bjorksten, B., Sampson, H.A. et al., 2000). Food allergens consumed by lactating mothers have been found in minute quantities in breast milk (Caffarelli, C., Cavagni, G., Bertolini, P. et al., 1988).
Ever since day one, people have been developing and creating all sorts of new methods and machines to help better everyday life in one way or another. Who can forget the invention of the ever-wondrous telephone? And we can’t forget how innovative and life-changing computers have been. However, while all machines have their positive uses, there can also be many negatives depending on how one uses said machines, wiretapping in on phone conversations, using spyware to quietly survey every keystroke and click one makes, and many other methods of unwanted snooping have arisen. As a result, laws have been made to make sure these negative uses are not taken advantage of by anyone.
Are you a pregnant mother or just recently had a baby? All mother’s want the best for their children. Multiple studies have shown that breastfeeding should be highly considered. Although, breastfeeding and bottle feeding are both alike in few ways, the numerous benefits of breastfeeding make it the best optimal for many mothers. Mother’s breast milk partakes over 100 ingredients, which therefore formula milk does not partake. Breastfeeding is better because of the price, the convenience, and all the wonderful numerous health benefits.
Breast milk matches a baby’s needs and growth patterns better than any formula substitute. A mother tends to produce just enough milk to fill her baby’s stomach, so she does not need to worry about underfeeding or overfeeding. Furthermore, the milk’s content changes as the ...
The fist computer, known as the abacus, was made of wood and parallel wires on which beads were strung. Arithmetic operations were performed when the beads were moved along the wire according to “programming” rules that had to be memorized by the user (Soma, 14). The second earliest computer, invented by Blaise Pascal in 1694, was a “digital calculating machine.” Pascal designed this first known digital computer to help his father, who was a tax collector. Pascal’s computer could only add numbers, and they had to be entered by turning dials (Soma, 32). It required a manual process like its ancestor, the abacus. Automation was introduced in the early 1800’s by a mathematics professor named Charles Babbage. He created an automatic calculation machine that was steam powered and stored up to 1000 50-digit numbers. Unlike its two earliest ancestors, Babbage’s invention was able to perform various operations. It relied on cards with holes punched in them, which are called “punch cards.” These cards carried out the programming and storing operations for the machine. Unluckily, Babbage’s creation flopped due to the lack of mechanical precision and the lack of demand for the product (Soma, 46). The machine could not operate efficiently because technology was t adequate to make the machine operate efficiently Computer interest dwindled for many years, and it wasn’t until the mid-1800’s that people became interested in them once again.
There are many times that computers can help humans do things that could not be done by hand. Many of these things can be expressed mathematically as a sum but can not be calculated on paper because of the extremely large number of simple calculations. The example that I've been working with is the sum of electric fields and the field lines they can produce. It is easy to acquire the electric field vector due to a set of charged particles at a given point, but to create a smooth line that follows those vectors requires more computing power than just a paper and pencil. While there are specific rules for drawing field lines, they don't draw the pictures for you. It may be easy to follow these rules and in a simple system (only two or three charges), but a computer is needed to keep the rules in check for more complicated systems.
The advantages of technology and the internet have led more criminals to use cyberspace to commit crimes. The threat of cybercrime is increasing as globalization continues to spread across the world. While the impact of globalization has led to amazing, new discoveries throughout the world, Internet connectivity has also made cybercrime easier. America and the rest of the world have become more reliant on technology and use it in more aspects of their lives, technology-users make themselves more vulnerable to cyber attacks. Globalization and the growing use of computers in the world have given people a motive to learn more about computing and become more knowledgeable as programmers. As these people learn more, there is a risk that they will use their new intelligence to commit cybercrimes.
The Computer that you know these days is a small thing that sits on a desk in your room that is composed of a monitor, keyboard, mouse and a small box. But computers have changed so much that if you seen old computer you would never recognize it. The first computer was built in the early 17 hundreds. You probably heard that the first computer was made in the 1950’s but computers have been around for hundreds of years.
