1.4 Types of Computer in our Society 1. Analog Computers
Analog Computer is a computing device that works on continuous range of values. The results given by the analog computers will only be approximate since they deal with quantities that vary continuously. It generally deals with physical variables such as voltage, pressure, temperature, speed, etc.

2. Digital Computers
On the other hand a digital computer operates on digital data such as numbers. It uses binary number system in which there are only two digits 0 and 1. Each one is called a bit.
The digital computer is designed using digital circuits in which there are two levels for an input or output signal. These two levels are known as logic 0 and logic 1. Digital Computers can give more accurate and faster results.
Digital computer is well suited for solving complex problems in engineering and technology. Hence digital computers have an increasing use in the field of design, research and data processing.
Based on the purpose, Digital computers can be further classified as, * General Purpose Computers * Special Purpose Computers
Special purpose computer is one that is built for a specific application. General purpose computers are used for any type of applications. They can store different programs and do the jobs as per the instructions specified on those programs. Most of the computers that we see today, are general purpose computers.

3. Hybrid Computers
A hybrid computer combines the desirable features of analog and digital computers. It is mostly used for automatic operations of complicated physical processes and machines. Now-a-days analog-to-digital and digital-to-analog converters are used for transforming the data into suitable form for either type of computation.

4. Super Computers
When we talk about types of computers, the first type that comes to our mind would be…...

Impact of Drugs in Our Society

...t of drugs in our society Impacts of Drugs in our Society The importation of illicit drugs in the United-States is a close second to the import of petroleum. According to the NIDA, drug abuse has an economic impact on society of $67 billion per year. This includes costs related to crime, drug abuse treatment, medical costs and time lost from work and social welfare programs. NIDA also states that getting treatment can reduce these costs. Centers for Disease Control and Prevention (CDC) reports that more than 25,000 people died in 2003 from drug-induced effects. CDC further reports that 123,235 adults living with AIDS in the United States in 2003 contracted the disease from injection drug use, and the survival rate for those persons is less than that for persons who contract AIDS from any other mode of transmission. A close connection exists between crime and drug use. Alcohol and drugs account for 52 percent of all traffic fatalities, according to the Hazleden Foundation. In the U.S., 47% of all women diagnosed with AIDS are injecting drug users and another 19% report having sex with users who inject drug. Drugs and Crime There is a high impact on Society of drugs. It was found that drugs and crimes are interrelated, as demonstrated by researches done by the United States National Institute of Justice. The major impact on drug-addicts is that they prone to commit crimes.......

Inequality in Our Society

... STATE AND DISCUSS FIVE FACTORS OF INEQUALITY IN OUR SOCIETY In this course we will investigate what causes gender inequality. This question is of great importance and it is a very general question that immediately implies a variety of more specific questions. Why has gender inequality seemingly existed in all known societies? Why did gender inequality arise originally? Why did gender inequality persist even as technological and cultural evolution overwhelmingly transformed social, economic and political organization? What is it that people do that sustains gender inequality across generations? The closer and more critically we examine the issues, the more questions about causation we confront. In general, this course will concentrate on explaining inequality between women and men: how does it arise why does it take different forms, why does it vary in degrees across societies; what are the components that add up to gender inequality how do various institutions and practices contribute to it and how does it changed the course will emphasize the history of gender inequality in the United States. While we focus on gender inequality, we will also seek to understand social causation more generally, we will explore the diverse ways social causation works and how we can identify the causes behind important social phenomena. Introduction: What do we mean by inequality? How can we conceive of and talk about gender inequality in ways that are general enough to apply across......

Our Dependence on Computers Is Detrimental

...Modern Computer Systems are Detrimental to our Human Instincts Lenny Miller Post University Dependence on Modern Computer Systems is Detrimental to our Human Instincts With every year that passes, we are becoming increasingly dependent on computers. From the first punch card readers to the iphone 5, computers have had a profound and sustaining effect on humanity. Since computers were first used in the medical field in the early 1960’s, specifically in bio-engineering, the lifespan of the average American has gone up 9.6 years. Computers have essentially shrunk the size of the earth as we know it by aiding us in travel, navigation, communication, and networking. Long gone are the days of months-long voyages and correspondence by pen and paper, taken by ship or horseback. The amount of information made available by computers is vast and practically unending. For these reasons and more, it’s hard to discount the positive impact computers have had on society. However, over-looked in all the praise of computers is the fact that they have eroded our ability to function independently. From math abilities to social skills and the ability to navigate from point A to point B, the negative aspects of computers are starting to outweigh the benefits. Our dependence on modern computer systems is detrimental to our human instincts. How many times in your adult life have you been faced with a fairly simple mathematical equation, such as figuring out a 20% tip on a $50......

Women in Our Society

...Women in our society Engineer Patricia Galloway believes that serving as the first woman president of the 151-year-old American Society of Civil Engineers - a historically male bastion if there ever was one - makes her a role model to women in the industry. It's high times for women leading construction-related engineering groups, with three others currently in high office. The same goes for construction organizations. Nova Group's Carole L Bionda is chairelect of Associated Builders and Contractors. Meanwhile, the US House Education and Workforce Committee last month passed the Family Time Flexibility Act (H.R. 1119) which could undermine workers' most basic rights by altering the Fair Labor Standards Act (FLSA), which currently requires employers to pay overtime to certain employees when they are required to work beyond the normal 40 hour work week.( Peterson 98) At home, we're aware (perhaps painfully so) that men and women often have different communication styles. But it's easy to forget that such differences can show up at work, too. To do an effective job of communicating, keep in mind gender-related communication styles. Young boys are socialized to give an immediate answer or solution to a problem. Young girls want answers, too, but tend to talk things over to solve problems. So while a man might prefer to work things out for himself, a woman is more likely to want to discuss them. According to researcher Deborah Tanhen, author of Talking from 9 to...

So always try to advance to a higher paying job. So respect can do lots of things that will help us with our future. So never stop caring! Respect isn’t the only right thing to do, but is also the best way to make a lot of friends. You being respectful will help you from being depressed from loneliness. You should be honest, kid, nice, gentle, relaxed, and happy to make friends. The word respect is a word to summarize all of the things above and plenty more. Things like being quite while someone is talking, or not bothering someone when they’re in bad mood. I see respect all the time, that’s what makes everything so easy to do and no one gets sad. If I ever saw someone get knocked over and their stuff is on the ground scattered all over, I would......

Types of Societies

...classified the different types of societies into six categories, each of which possess their own unique characteristics: 1. Hunting and gathering societies 2. Pastoral societies 3. Horticultural societies 4. Agricultural societies 5. Industrial societies 6. Post-industrial societies Hunting And Gathering Societies Hunting and gathering societies are the earliest form of society. The members survive primarily by hunting, trapping, fishing, and gathering edible plants. A majority of the members' time is spent looking for and gathering food. A hunting and gathering society has five characteristics: 1. Family is the society's primary institution. Family determines the distribution of food and how to socialize children. 2. These societies are small compared to the others. They generally have less than 50 members. 3. Hunting and gathering societies are nomadic, which means that they move constantly in order to find food and water. 4. Members of hunting and gathering societies are mutually dependent upon each other. 5. Although there is equal division of labor among the members of hunting and gathering societies, there is division of labor based on sex. Men are responsible for hunting and women are gatherers. Pastoral Societies Pastoral societies began around 12,000 years ago. These societies rely on products obtained through the domestication and breeding of animals for transportation and food. Pastoral societies are common in areas......

Media Influence Our Society

...Media plays a significant role in our society today. It is all around us, from the shows we watch on television, the music we listen to on the radio, to the books and magazines we read each day. Television more so that any of the other medias achieves a myriad of different goals. These goals range from entertaining to educating. Various confines of education and entertainment are depicted in television. For the most part the television is found to be very entertaining. People watch television shows they enjoy and find entertaining. Television is often looked at as a babysitter for children. The viewing of television can entertain the young and old alike for great amounts of time. Along with entertaining, the media is used to inform society. Days are often started by the listening of the news on the morning television, judging the latest updates on the local traffic jams. Days are often concluded with the watching of the late night news on television, keeping us informed of the world and the events occurring around us. Steven Stark, author of Glued to the Set has been quoted as saying, "the local newscast has replaced the network news and the newspaper alike as the average American's main source of news." (390) In addition to informing the television is used to spread a message or to campaign. Political candidates on all levels use this medium to inform the public of their views and hopefully to convince the public to elect them. James B. Twitchwill author of Adcult......

Pollution in Our Society

...Pollution Pollution is an issue of concern in the modern world that we live in today. There are many types of pollution, namely air, water and noise. Pollution in our environment will undoubtedly affect our quality of life. Our naturally beautiful world becoming ugly because it is suffering from the effects of environmental pollution. Pollution can also cause various health problems and other negative effects. Air pollution is caused by the emission of toxic gases from vehicles, factories and open burning. Nowadays, there are more and more vehicles on the road as society gets more affluent. More and more people strive to have a better quality of life by having the convenience of driving to their destinations instead of taking public transportation. Automobiles provides transport to millions people around the world to enable them to travel to their workplace, school and other places, therefore, the air around us is getting more polluted by the carbon dioxide that is emitted. Carbon monoxide is another type of gas which harmful to the environment as it can cause the reduction of oxygen in the bloodstream. Another example of contributor to the air pollution is the manufacturing factories. The manufacturing of products in factories to meet the growing demand of society is also causing air pollution. Factories release toxic gases to the environment. Some factories also use coal to generate heat and energy. As a result from the burning of coal, carbon dioxide is released......

Types of Societies

... Types of Societies. 1. Hunting and Gathering Societies 2. Horticultural and pastoral Societies 3. Agrarian Societies 4. Industrial Societies 5. Postindustrial Societies 1. Hunting and Gathering Society is the society of people that have their sustenance dependent on hunting wild animals, fishing, and gathering wild fruits, berries, nuts, and vegetables to support their diet. Before humans started to plant their foods and keep animals or tend animals for domestic use, all humans’ societies were hunter and gatherers. Hunter-Gathering societies are usually mobile, moving from one place to another in other to look for foods and water. The type of division of labor practiced by this type of society was solely based on gender, men will hunt while women gathers. This period can be traced back to about ten thousand years ago, and there are still some part of the world that can be classified as Hunter-Gatherers today, but they are very few and not easy to come by. Most often, these societies live in isolated and less hospitable areas like rain forests, savanna area. An example will be the Hadza society in the Eastern rift valley of Northern Tanzania. 2. Horticultural and Pastoral societies are the societies that cultivates fruits, vegetables, and plants. These type of societies started a......

Single Mothers in Our Society

...Ashley Viera Sociology1 Professor Vajezatha February 27, 2016 “Single Mothers and Our Society” Growing up in an environment where we have to grow up with limited expectations, makes us think mediocrely and make our lives unsuccessful. We can’t let our surroundings determine our abilities. Reading and analyzing “How Single Motherhood Hurts Kids” by Kay S. Hymowitz I noticed that she made a very clear argument on how being single mothers brings inequality and poverty to our society. This lead to how I can analyze single mothers through sociological imagination. Single mothers in fact are being vigorously expanded by the help of governments support. Single mothers in the United States aren’t suffering as much if they were to live elsewhere without any support. According to this article it shows that whether you live in a community were being a single mother is the norm, girls see no other alternative of a successful life choice. This shows that when you come from a low income family having a child at such a young age is expected from you because of your surroundings. Not including that many women stop using birth control several weeks after starting a sexual relationship. Most of the time when women don’t grow up with a father figure and have a daughter it most likely for the child to hurry and find replacement and try to feel love. Then in this case it’s when girls at such a young age gets pregnant because men don’t take full responsibilities of their actions and go......

British Type of Multicultural Society

...ESSAY British type of multicultural society In less than three decades «multiculturalism» has become a world immediately recognized by policy makers, social commentators, academics and the general public in Western industrial countries, if not elsewhere. Britain is not an exception. In this case it is necessary to discuss pluses and minuses of multicultural society. The UK has welcomed newcomers for centuries. It is a mixture of diverse ethnic groups, each with their own distinct culture and sometimes their own language or religion. In my point of view, there are more negative sides of multiculturalism in the UK than benefits. One argument in support of my opinion is the fact that multiculturalism in Britain causes immigration crime and terrorism. At the beginning of the 21st century, the multiculturalism started to be seen from race relations to religion, religion is clearly seen in a cultural context. All this led to numerous acts of terrorism and crimes based on religion. Also the widening gap in cultures has caused more segregation and fear in many communities, and has created more radical organizations which are visible on both sides. Also it is a well-known fact that the UK is a prime example of realization of the model of "hard" multiculturalism: the country has not only developed and actively implements a broad system of measures to support national minorities to preserve their identity, culture, traditions and customs. But also has adopted a number of laws to......

Is Our Consumption Society Sustainable

...Is our consumption society sustainable? The concept of a sustainable society has been discussed for decades. Moreover, attention is paid to the direct effect that consumption has on this issue. Sustainability is defined through meeting consumer needs without compromising the needs of future generations (OECD, 2002). But it doesn’t bring in question what quantity of current needs is really necessary (Conca, Princen& Maniates, 2003). Many scientists regard consumption orientated society as the main culprit for the destruction of our planet. What is known until now is that consumption patterns had a large impact on the environment in the last 50 years. One of its consequences is global warming that altered our climate (Cahill, 2001). But the dreading consequence lies in the amount of waste with which these patterns burden our planet, through the process of production and even more after the death of the product. The products are made with a short life-cycle in mind, but in order for the golden arrow of consumption to be strong, consumers are convinced to throw away the product even before its expiration date. Making the product obsolete while it is still able to perform degrades the environment. However, there are also business oriented people who regard consumption as a driver for economy advancement. This paper will address the estimated consequences of these two views and try to analyze the milestones in attempt to identify the direction in which our consumption......

Manners in Our Society

...Manners in Our Society I used to get annoyed at my father for judging the type of music and television that I liked and not allowing it at home when I was growing up. I have since gained a respect for what my parents were “judging”. Children do not pay attention to actual content and a lot of messages can be slipped into a catchy tune or a popular program. My parents were right these influences do have an effect upon how “kids these days are raising themselves”. Manners have declined due to disrespectful music lyrics, anti-authoritative television programming and parents not paying attention to what influences their children in media The lyrics in music have gotten more disrespectful as time has gone by. Parents need to pay attention to what their children are really hearing. How have we gone from Louie Armstrong’s, “It’s A Wonderful World” to Twisted Sister’s, “We’re Not Gonna Take It”? When I was growing up in the 1970’s my parents did not approve of music in our home with bad messages, morals and attitudes. Led Zeppelin’s “Stairway to Heaven” was considered demonic and was definitely not played in our home. When I had my own children I understood my parents point of view. I also found myself banning certain music from our atmosphere at home as well. I noticed how much more disrespectful it had gotten from the 1970’s to the 1990’s and 2000’s. Eminem and Dr, Dre for example are not role models I wanted my children idolizing at all. The role......

Types of Computers

...TYPES OF COMPUTER Let us discuss the different types of computers that we see today. Although they belong to the fifth generation they can be divided into different categories depending upon the size, efficiency, memory and number of users. Broadly they can be divided it to the following categories. 1.Microcomputer: Microcomputer is at the lowest end of the computer range in terms of speed and storage capacity. Its CPU is a microprocessor. The first microcomputers were built of 8-bit microprocessor chips. The most common application of personal computers (PC) is in this category. The PC supports a number of input and output devices. An improvement of 8-bit chip is 16-bit and 32-bit chips. Examples of microcomputer are IBM PC, PC-AT . 2.Mini Computer: This is designed to support more than one user at a time. It possesses large storage capacity and operates at a higher speed. The mini computer is used in multi-user system in which various users can work at the same time. This type of computer is generally used for processing large volume of data in an organisation. They are also used as servers in Local Area Networks (LAN). 3.Mainframes: These types of computers are generally 32-bit microprocessors. They operate at very high speed, have very large storage capacity and can handle the work load of many users. They are generally used in centralised databases. They are also used as controlling nodes in Wide Area Networks (WAN). Example of mainframes are DEC, ICL and IBM 3000......
