Inventors of the Modern Computer

In November of 1971, a company called Intel publicly introduced the worlds first single-chip microprocessor, the Intel 4004 (U.S. Patent #3,821,715), invented by Intel engineers Federico Faggin, Ted Hoff, and Stanley Mazor. After the invention of integrated circuits  revolutionized computer design, the only place to go was down -- in size that is. The Intel 4004 chip took the integrated circuit down one step further by placing all the parts that made a computer think (i.e. central processing unit, memory, input and output controls) on one small chip. Programming intelligence into inanimate objects had now become possible. The History of Intel In 1968, Robert Noyce and Gordon Moore were two unhappy engineers working for the Fairchild Semiconductor Company who decided to quit and create their own company at a time when many Fairchild employees were leaving to create start-ups. People like Noyce and Moore were nicknamed the Fairchildren. Robert Noyce typed himself a one-page idea of what he wanted to do with his new company, and that was enough to convince San Francisco venture capitalist Art Rock to back Noyces and Moores new venture. Rock raised $2.5 million dollars in less than 2 days. Intel Trademark The name Moore Noyce was already trademarked by a hotel chain, so the two founders decided upon the name Intel for their new company, a shortened version of Integrated Electronics. Intels first money-making product was the 3101 Schottky bipolar 64-bit static random access memory (SRAM) chip. One Chip Does the Work of Twelve In late 1969, a potential client from Japan called Busicom, asked to have twelve custom chips designed. Separate chips for keyboard scanning, display control, printer control and other functions for a Busicom-manufactured calculator. Intel did not have the manpower for the job but they did have the brainpower to come up with a solution. Intel engineer, Ted Hoff decided that Intel could build one chip to do the work of twelve. Intel and Busicom agreed and funded the new programmable, general-purpose logic chip. Federico Faggin headed the design team along with Ted Hoff and Stanley Mazor, who wrote the software for the new chip. Nine months later, a revolution was born. At 1/8th inch wide by 1/6th inch long and consisting of 2,300 MOS (metal oxide semiconductor) transistors, the baby chip had as much power as the ENIAC, which had filled 3,000 cubic feet with 18,000 vacuum tubes. Cleverly, Intel decided to buy back the design and marketing rights to the 4004 from Busicom for $60,000. The next year Busicom went bankrupt, they never produced a product using the 4004. Intel followed a clever marketing plan to encourage the development of applications for the 4004 chip, leading to its widespread use within months. The Intel 4004 Microprocessor The 4004 was the worlds first universal microprocessor. In the late 1960s, many scientists had discussed the possibility of a computer on a chip, but nearly everyone felt that integrated circuit technology was not yet ready to support such a chip. Intels Ted Hoff felt differently; he was the first person to recognize that the new silicon-gated MOS technology might make a single-chip CPU (central processing unit) possible. Hoff and the Intel team developed such an architecture with just over 2,300 transistors in an area of only 3 by 4 millimeters. With its 4-bit CPU, command register, decoder, decoding control, control monitoring of machine commands and interim register, the 4004 was one heck of a little invention. Todays 64-bit microprocessors are still based on similar designs, and the microprocessor is still the most complex mass-produced product ever with more than 5.5 million transistors performing hundreds of millions of calculations each second - numbers that are sure to be outdated fast.

Genetically Modified Organisms ( Gmos ) Essay - 1463 Words

Introduction The concept of intentionally altering a naturally occurring organism’s DNA in order to produce genetically modified organisms (GMOs) has been critically analyzed by both science and the mainstream media in the last decade. However, the genetic modification of organisms is not a recent innovation as humans have been modifying organisms for over 30 000 years (Rangel, 2015). Back then, breeding through artificial selection was the most prominent method of genetic engineering. Organisms with the most desirable traits would be bred together in order to create a new generation of superior organisms. Throughout the centuries, the developments in science and technology have resulted in new methods of genetic engineering. Now, genomes can be spliced in order to insert or remove genes. It has essentially come down to a copy and paste process with genes from animals being inserted into plants as the common practice. GM foods are developed by scientists because there is some perceived advantage either to the producer or consumer. For a GM food to be of theoretical benefit to the consumer and society as a whole, it should: increase crop yields due to the introduced resistance to pests and disease, enhance the nutritional profile of an organism or increase the shelf life (Phillips, 2008). Based on the projected benefits of GMOs, it is reasonable to ask and address the question of whether GMOs are capable of alleviating the societal issues of world hunger and poverty.Show MoreRelatedGenetically Modified Organisms ( Gmo )1665 Words   |  7 PagesA genetically modified organism (GMO) is a chemical organism processed in a laboratory where genes from the DNA of the crops are extracted and then artificially forced into an unrelated product that, when put into the crops the farmers raise, can chemically change the makeup of the crop.

Nixon’s “Southern Strategy” and Forces Against Brown Free Essays

Do you remember your first day of school ? How was it ? Was it scary? I bet going to a segregated school where you were getting all types of looks , its way different the early 1900’s. from people judging you about the clothes you were to the style of your hair. This article discusses Richard M . We will write a custom essay sample on Nixon’s â€Å"Southern Strategy† and Forces Against Brown or any similar topic only for you Order Now Nixon , the United States President in 1968 gave birth to the modern reform movement through public vouchers and other educational reform measures under his † Southern Strategy † that was designed to gain the votes of individuals who oppose school desegregation . The political activities in school desegregation after Brown by the two major political parties , namely the democrats and the republicans are discussed. President Richard Nixon reacted to the 1971 court decision on Swann verses Charlotte- Mecklenburg school district , a school desegregation case that approved to use of race to assign students to school by the use of busing , by instructing the U.S. justice department to draft a constitutional amendment to nullify the court’s decision. (Kruger 1975 ) In my view President Richard Nixon was just trying to get white American votes . Bussing is still going today for example ; where I stay I’m between two elementary school’s and you would think that my children could attend both schools but that’s not the case . I guess the way the school district resolved the issue was by halving up the neighborhood. Which I consider crazy because back when I was going to school my road in particular wasn’t considered a bus stop and our parents were able to choose whichever school .they wanted us to attend . Now , the way they separated the neighborhood the cut off spot or road I should say is the road right before mine . We didn’t have that problem because we had to go to the next road anyway to catch the bus the same exact road they use as a cut off for the first elementary school. I think its so selfish how we as a people can’t get along enough to join and become equal enough to get an education . I thought that was the reason for the separate but equal doctrine . Opposition to school desegregation was intense from the beginning and continues to this day ; and the results are clear , that is , the whitest American do not support school desegregation ( Jeffries , 1994 ; Motley , 1998 ; Olgetree , 2004). This is so true because In 1970 , Vigor High School on Wilson Avenue , which had been Prichard’s white high school during segregation , was 70% white . By 1980 , It was 80% black . Although most of Prichard’s remaining majority-white areas were in this district , many families had put their students into parochial or private schools . Before this came about Prichard was predominately white until they move black in the area to work at the paper mill. I totally agree with frank browns argument favoring integration on buses and in all areas of public accommodation and travel . Human beings have struggled with / on centuries to gain equal rights . Western civilization has been characterized by the hegemonic domination by white males. This power structure has frequently and historically excluded women and minorities . In the United States , despite the foundational creed that † all men are created equal , † it has taken centuries of struggle to gain equal rights . Equal rights , of equality before the law , means that all individuals are subject to the same laws of justice. People must be treated equally with / as / for regard to race , gender , national origin , skin color , religion or disability. African Americans were one of the first groups granted equal rights in the United States , through the passage of the 14th Amendment , which outlawed slavery . Achieving equal rights in reality took another century of struggle . Women , as well , although granted the right to vote for / by 1920 , continue to work towards equal rights , most recently through pay equity . Congress should terminate all programs because of the harm they caused minority students. I am so glad they passed the Title VI of the Civil Rights Act of 1964 states that No person in the United States shall , on the ground of race , color , or national origin , be excluded from participation in , be denied the benefits of , or be subjected to discrimination under any program or activity receiving Federal financial assistance . Equality means everyone has an identical quantity of everything ; no one is considered superior or inferior. Equality means that all children can grow up and go to school with equal access to the English language here in America . Everyone should be treated as fairly and as worthy of respect and basic rights as their peers from the moment they are born . People being able to be themselves , walking through life with inherent characteristics that should be considered neutral such as ethnicity , skin color , gender , physical disabilities , mental disability without having to face discrimination based on their presence or characteristics.

Type of Crime That Use It Systems as Weapons free essay sample

Computer crimes are criminal activities, which involve the use of information technology to gain an illegal or an unauthorized access to a computer system with intent of damaging, deleting or altering computer data. Computer crimes also include the activities such as electronic frauds, misuse of devices, identity theft and data as well as system interference. Computer crimes involve activities of software theft, whereas the privacy of the users is hampered. These criminal activities involve the breach of human and information privacy, as also the theft and illegal alteration of system critical information.The different types of computer crimes have caused the introduction and use of newer and more effective security measures. Out of the many crimes that use IT systems, the one that cost us the most would have to be identity theft. Biegelman states, â€Å"Simply put, identity theft is the stealing of your good name and reputation for financial gain. We will write a custom essay sample on Type of Crime That Use It Systems as Weapons or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Yet not everyone can agree on a suitable meaning of the term. The definition of this crime differs among law enforcement, regulatory agencies, and the many studies of this subject† (2). There is big money at stake and the financial rewards for criminals are almost limitless, they go to amazing lengths to defraud their victims. The Federal Trade Commission (FTC) estimates that as many as 9 million people have their identities stolen each year (FTC, 2012). Experts agree that identity theft is a serious problem, and special precautions must be taken to avoid it. When people become the victims of identity theft, they are unaware of what just happened, and they need answers. According to the FTC, Identity theft is serious.While some identity theft victims can resolve their problems quickly, others spend hundreds of dollars and many days repairing damage to their good name and credit record. Some consumers victimized by identity theft may lose out on job opportunities, or be denied loans for education, housing or cars because of negative information on their credit reports. In rare cases, they may even be arrested for crimes they did not commit. (FTC 2012) One way of stealing someone’s identity is by Phishing. Phishing is an attempt to lure unsuspecting computer users to phony web sites that mimic the sites of legitimate businesses or public or government organizations. These copycat cites trick users into revealing private and sensitive information such as their usernames, passwords, and account numbers. This information is then used by or sent to criminals’’ (Ross 69). There is also skimming which occurs when a dishonest employee of a company steals customer’s information, such as their credit card number.This type of fraud usually happens in bars and restaurants, because the waiter will take your card to process the bill. Once they have your card, they will photocopy it, or use an electronic skimmer device to pick up the numbers. The person will use the credit cards later to make online purchases, or transfer money to their accounts. Criminals also engage in dumpster diving, which is going through a person’s trash, to obtain copies of checks, credit card and bank statements, or other personal records that bear your name, address, and even your telephone number.These types of records can help a thief; get control over your accounts or your identity. Credit card companies send pre-approved applications to consumers, and if they are not destroyed before going to trash, the thief may get access to the trash, and activate the credit cards, without the person’s knowledge. United States Department of Justice states that, â€Å"Some credit card companies, when sending credit card applications, have adopted security measures that allow a card recipient to activate the card only from his or her home telephone number, but this is not yet a universal practice† (USDOJ, 2012)Many of us are very hesitant to shop online because of the looming threats of identity theft. For those of us that are concerned because of the frequent use of personal information online the best way to keep track of your information is to monitor your accounts and bank statements each month, and check your credit report on a regular basis. If you check your credit report regularly, you may be able to limit the damage caused by identity theft. â€Å"Most people find out that they are victim of identity theft, after damage has been done to them.Filing a police reports, checking your credit reports, notifying creditors, and disputing any unauthorized transactions are some of the steps you must take immediately to restore your good name† (FTC, 2012). If you believe you are a victim of mail fraud, contact the postal inspection services immediately. If someone has used your social security number, contact the Social Security Administration to file your case. Also contact the three credit reporting agencies and have them place a freeze on your account.The Federal Trade Commission states, â€Å"It is best to close all your accounts in writing, so that you have proof of contacting the company, in case something goes wrong† (FTC, 2012). There are a few easy ways to help prevent identity theft. One identity theft victim says, â€Å"When you move and fill out the change of address card, be sure to watch for a letter from the Post Office at your new address confirming that you have changed your address. If you do not get the letter within a couple weeks, be sure to check with the Post Office to make sure they indeed paid attention to your change of address† (Privacy Rights, 2002).Lastly, Elisabeth Goodridge states, Balancing your checkbook may seem a monotonous chore, but understanding where your money goes will help you spot any irregular withdrawals or charges. Reviewing your credit card bill each month is critical as well, especially if you charge a lot of your daily purchases. If you have not already, this may be a great time to sign up for online accounts. It’s easier and faster to review accounts online, on a computer you trust. (2009) IT system crimes are clearly on the rise as more companies, organizations, and individuals are more connected to the internet, and this trend does not appear to be slowing down.
