QUESTION: Describe the computer generations based on the following : 1. Hardware 2. Software 3. Computing characteristics 4. Physical appearances 5. applications
A computer is an electronic device capable of accepting data, processing it, giving it out and storing it for later use. Computers have evolved over the years from large sized computers to small sized version which we called the generation of computers. The computer generations are as follows: a) First generation b) Second generation c) Third generation d) Fourth generation e) Fifth generation
First generation computers
The first generation computer was designed and built based on vacuum tube technology. The first generation computers were manufactured from 1940 to 1956.These vacuum tubes were used to perform logic operations and to store data
In this generation of computers there was no best way of storing instructions and data in a computer memory. Punched cards and paper tapes were invented to feed programs and data to get results. The magnetic tape or magnetic drum were used as secondary memory and the output was displayed as printouts.
The instructions and data were written in machine language. The machine language used O’s and I’s for coding of the instructions. These first generation computers could solve one problem at a time. The computation time was in milliseconds

Younger Generation

...with the Younger Gen The Problem with the Younger Generation Today Good afternoon, my name is Randy Daniels and I am pleased to have the opportunity this afternoon to give my thoughts on a subject that anyone over the age of 30 has an opinion on - that is the younger generation and their associated faults. My view of this so called problem is that there is really no problem at all; it is simply generational bias at work. Every generation thinks the next generation is lacking in some basic knowledge or skill that is vitally important to the continuation of the human race. Often, however, we find out that in time that skill, ability or knowledge will surface or were totally unnecessary in the first place. First, please understand that by “young people” I am not referring to anyone under the age of 17. These teens live in a sub-culture that no one over that age understands. There is good reason why retail shopping malls have imposed a ban on these so called young shoppers unless they are accompanied by an adult. Many of the young people I see today can solve problems and the solution is almost always correct. They just go at it differently. While my generation, my parents generation and those before might work out several possibilities and try to devise the best solution, the young people of today use Google and instantly have the opinion of several experts. Ask yourself this question; if we had had computers in our day wouldn’t we be doing the same thing? In......

...THE MAYAN REALM The Mayans created a great civilisation in parts of what are now Mexico and Honduras and in Guatamala. The ancestors of the Mayans were hunters but about 2,500 BC they adopted farming as a way of life. In the years from 300 BC to 250 AD organised Mayan kingdoms emerged. Then from 250 AD to 600 AD an advanced civilisation emerged. The Mayans invented writing and they made great advances in astronomy and mathematics. MAYAN LIFE Mayan Society In the centre of each Mayan city was an area of palaces, pyramid temples (some of them 70 metres high) and squares, where religious ceremonies were held. In the squares were stelae (upright stones) which were carved with the dates of important ceremonies and events. Ordinary people lived in the surrounding houses. Most of the Mayans lived in the countryside but many cities were large. Some had populations of 45,000. Below the rulers were the nobles and priests. Below them were freemen, craftsmen and farmers. Below them were slaves who did all the hardest work. The Mayans did not have animals for carrying loads. All goods were carried by human beings. The Mayans did not have metal tools. All their weapons and tools were made from wood and stone. However the Mayans invented a system of writing using pictures to represent sounds. Writing was painted onto books made from fig tree bark. It was also painted on pottery. Unfortunately the Spaniards burned many Mayan books so little is known of their history. The Mayans......

Internet Generation

...The Internet Generation For most of my life I have been fortunate enough to be able to interact with computers and the internet. Although this is a good thing for me, it doesn’t blind me to the fact that there are some people who just don’t understand the concepts of a computer and the internet. The "computer generation" is not just for one generation. The elderly don't have to sit back and watch while the younger generations have fun banking, playing, shopping and socializing online. But many elderly people shy away from computers out of fear, wondering "What if I break it?" or "What if someone steals all my personal information?" The concern over the growing “digital divide” has led to a number of initiatives being employed to encourage web usage for the older generations, and to ensure they are not excluded from the digital world. Among these is educating the elderly on ways computers may benefit their lives. Some computer manufacturers have designed computers especially for elderly users. The designs acknowledge seniors' limitations on a computer, attempting to make a comfortable user for them. For instance, the designs tend to emphasize simplicity and straightforward commands and prompts. Keyboards are less cluttered with keys, and the software lacks design complications. The computers also make the tasks common to elderly users, such as email or viewing photos, easy to access and operate. These are just a few ways companies as well as new technology make it......

Parenting Generation

...Parenting Generation Practices Jessica Rivera Faculty: Trent Koide Argosy University May 28, 2014 Abstract Day by day our generation seems to change as years go by. Back then parents were very strict with their children. There are so many changes that have occurred and will continue to do so. For instance children had respect for their parents. Parents or guardians would takecare of children. These days Parents or guardians are doing their own thing for instance some spend time working till wee hours of the night some all they do is spend time on the internet. Some children are not eating proper do to that factor. Back then parents or guardians put their children before anything and were always watching what they needed. Children sometime feel neglected that they do whatever they want because they no longer feel loved. There are so many things generations have changed like education, money managing, chores and meals. Keywords: changes, parents, children, generations, respect Parenting Generation Practices Everything has changed and will continue to change as a new generation starts to form. For instance, the old is gone and new starts to come. Father would tell my brother and me that when his grandpa was younger he had to wake up very early to feed the animals do chores around the house then eat breakfast. He would also say that his grandpa would tell him if I was to talk back I will get hit with a whip or I would not eat for a day. Dad would say that his......

...The Stolen Generations The term “Stolen Generations” is used for the Children of Australian aboriginal and Torres Strait Islander, most of the children were under 5 years old, who were taken from their parents by the Australian government and Church. They were separated from their parents and lived in dormitories or with foster parents. It is referred to “stolen generations” because it happened for many decades and several generations were affected. It is believed that these forcibly removals happened from around 1900s until 1970s. Approximately 100.000 children were stolen during that time. They had less contact with their parents or even didn’t know whether their parents were still alive or not. Nowadays, many of them are still searching for their families. There were many reasons to justify the Australian government actions includes to give them better living conditions because their aboriginal parents would only neglect them, to convert their beliefs into Christian by moving them from the cultural influence of indigenous people and to give them better education. However, the truth is, there was an assimilation policy that aboriginal people would die out if they have children with white Australians for generations and a fear of miscegenation by full-blooded aboriginal people. The term “Stolen Generations” is used for the Children of Australian aboriginal and Torres Strait Islander, most of the children were under 5 years old, who were taken from their parents by the......

Dependent Generation

...Alisha Nanda Mrs. Waller English 11H Period 2 March 5, 2015 The Dependent Generation June 20, 2016. The new predicted Doomsday. Huh, coincidentally, Doomsday lies on the date of my high school graduation, also known as the day society ends. Why? Well, because my generation, 1990-2003, is the dependent generation. We are dependent on technology, of course, but also dependent on parents. My generation is addicted to technology. The multitude of devices now readily available explains the origin of our dependence. Even teachers now use technology as part of their curriculum. Considering this fact, an argument stating that students do not actually need their many devices is proven invalid. Students indeed require their phones to be successful in school. For example, in physics, my classmates and I used our phones to videotape an oscillating spring to gather data for a lab. Therefore, the vital incorporation of technology into education forces students to own phones and partially justifies the use of technology, but it does not rationalize the obsessive use of technology. Inside and outside of school, all that matters is Facebook, Google, and Snapchat. Technology consumes three hours and sixteen minutes of our lives every day. (Woollaston) People today believe that they cannot live without our IPhones and Macs. Interestingly enough, many of these people have actually experienced a technology-free world, and therefore, know that it is possible to live without checking......

The Five Generations of Computers

...The Five Generations Of Computers The 21st century is the age of computer technology and it has brought about a major change in every aspect of our life. “It has largely changed the way we communicate and the way information exchange is used in today's world. The computer is a growing creation that is a result of advances of many other generations of computers, for example, the common personal computer, personal tablets, and even our smartphones, all came from the concepts of the previous 4 generations of computers” according to (Duncan, Becky) in her article over the importance of computers. This time and age we are now using the fifth generation of computers. Computers are so beneficial to the world today because, Computers are now a part of everyone's existence, including work, school, learning and play. Many modern activities, such as social media, information sharing and business applications require computers, and people cannot complete these actions without one. “The computer is an electronic device used in almost every field even where it is most unexpected. It is made up of two things one is the hardware and other is software. All physical components of computer like keyboard, mouse, monitor etc. comes under the hardware while all the programs and languages used by the computer are called software.” (Trigg, Paula). These days’ computers are the tools for not only engineers and scientists but also they are being used by millions of people around the world. First......

..."We have the power to make this the best generation of mankind in the history of the world or to make it the last." (John F. Kennedy). Every generation has similarities and differences from the one before, and the one after their time. The people living through that time determines if they will be known for something great. I believe every generation feels a need to leave a positive legacy to pass on. We as people are constantly advancing in social acceptance but where we grow and excel in some areas we start to lack in others. My parents generation and my own have varying differences on political correctness, biracial couples and being entitled. In my generation being politically correct is a must. Small children just entering the education system can tell you what being politically correct means and if what you are saying is correct or not. The media has made such a big deal over what is okay to say and what is not, which leads most people to be worried if they are offending someone. My generation is extremely accepting, women have rights along with African Americans, and gay couples. Most people want everyone to feel like their lives matter and that they are accepted especially minority groups. In order to make everyone feel accepted we have adopted political correctness so we do not offend anyone's choices, beliefs, race, morals, and sexual preferences. Even though being politically correct is important. I believe society is making too big a deal about needing to......

"IT Support: Bridging The Generation Gap" InformationWeek  (December 2015): Link : Pre-Script: Baby Boomers: Born before 1965 Gen X: Born between 1965 and 1980 Millennials :Born between 1980 and 2000 Millennials, digital natives who grew up with computers and Internets have much expectations regarding the technology they use rather than the baby boomers. These tech savvy workers will want more IT support via video chat, Instant messaging and social media rather than the Gen Xers and baby boomers. A CompTIA’s study was made based on the IT support needs in different age groups on an online survey across various sectors. CompTIA found that desktops and PC topped the list for IT support tickets rather than the smart phones and tablets. Millennials are more open to use skype or Lync video chat to work with IT Support compared to the boomers and they are more likely to use their own personal computing devices at work. The Survey also found that the millennials were inclined to “do it yourself” approach or search solutions on google than the Gen Xers or baby boomers.
