What are the advantages of using a computer? • Increase your productivity • Computers increase your productivity and, with a good understanding of the software running on them, you become more productive at everything you do. For example, once you have a basic understanding of using a word processor, you can create, store, edit, share, and print documents and letters. Each of these tasks was either impossible or slower with all pre-existing technologies. • Connects you to the Internet • Connecting a computer to the Internet unlocks its full potential. Once connected, your choices and available options, as far as information goes, are almost limitless. Many of the benefits listed on this page pertain to a computer connected to the Internet. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

What are the advantages of using a computer? • Society has come to rely heavily on computers. Computers affect nearly every aspect of our lives. Although there are disadvantages to using a computer, we believe the advantages greatly outweigh them. Parents, if you're on the fence about the decision on whether or not to buy your child a computer, perhaps these advantages can help convince you. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

What are the advantages of using a computer? • Get a better understanding of data • Computers can also give you a better understanding of data and big data. For example, a business could have a database of items they've sold. Using that data, they can quickly identify what sells best at what time of year, when to mark up or down items, and what items are not selling. Having access to this type of information gives the business a better understanding of their customers and a competitive edge against their competitors. • Keeps you connected • Computers help keep you connected with long-distance friends and family over e-mail and social networking. You can also connect with millions of other people who share your same interests through online forums, chat, and VoIP services, like Skype. Connecting to people worldwide is also an excellent way to meet people you would usually never meet. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

What is Computer? • A computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program, software, or sequence of instructions on how the data is to be processed. • A device, usually electronic, that processes data according to a set of instructions. The digital computer stores data in discrete units and performs arithmetical and logical operations at very high speed. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

What are the advantages of using a computer? • Help you learn and keep you informed • One of the most significant impacts computers have on our community is when computers are connected to the Internet. It is an educational tool that helps answer almost any question, teaching you anything that interests you. You can also access worldwide news to keep up-to-date with all of the latest news, weather, and stories around the world. You could learn a new profession by reading websites or watching videos. You could even sign up for online courses that teach you about any subject you'd learn in school. • Can make you money • When connected to the Internet, a computer could help you make money in many different ways. For example, creating and running an online store is cheaper than having a physical store. Also, once online, your store or product has a global audience, and you could sell to anyone in the world. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

What are the advantages of using a computer? • Can store vast amounts of information and reduce waste • Computers are capable of storing and accessing vast amounts of information. For example, a computer and devices like eBook readers can store hundreds or thousands of books, given enough storage capacity. By storing books, documents, movies, pictures, and songs digitally, you can quickly find what you need by searching and sharing information between devices. It eliminates the need for paper used to make non-digital versions of the media. • Helps sort, organize, and search through information • A computer can use its stored information more efficiently than any other device. In our earlier example, we mentioned the ability to store thousands of books. Once those books are stored on a computer, they can be sorted into categories, alphabetized, and searched to find what you're looking for in a few seconds. Trying to find the exact text in a thousand books would take a human months, if not years. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

What are the advantages of using a computer? • Improves your employment options • Knowing how to use a computer and having a computer can improve your employment options and even work from home.

Knowing how to use a computer and having a computer at home allowed many office workers to continue their work even during the crisis. Also, by getting skilled at computers, you'll be more qualified for other positions, allowing you to change your position or place of employment for higher pay. • Improves your abilities • Are you not the best speller, have poor grammar, not great at math, maybe you don't have a great memory, or need help with something else? Using a computer improves all your abilities, or if you have a hard time learning, you can rely on the computer as an assistant. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

What are the advantages of using a computer? • Helps automate and monitor • A computer can be programmed to complete a task and, once done, repeat that task as many times as needed. For example, a computer could be programmed to move a robotic arm that builds a part for a car or filter, sort, respond, and forward incoming e-mails. Programming a computer-controlled robot to do tedious, dangerous, or repetitive tasks allows humans to focus on enjoyable, safe, and non-repetitive tasks. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

The Limitations of the Computer • Computers are still far from reaching a few major milestones. Humans continue to surpass computers in some tasks. Computers may be able to get around these restrictions in the near future. The limitations of computers will be discussed, but for the time being, human labor is still indispensable. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

The Limitations of the Computer 1. No IQ: Unfed or unprogrammed events cannot cause a computer to react. They are incapable of learning anything (zero intelligent quotients). The user’s input determines these results entirely. That is, instead of correcting the incorrect input, they produce the incorrect result. 2. No feelings/ EQ: While the computer may function nonstop and relentlessly. Few activities, though, call for advice and concepts. Only those who have positive, negative, or mixed feelings about the task will be able to accomplish it. In these situations, a machine fails because it lacks emotional intelligence (EQ) (Emotional Quotient). donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

The Limitations of the Computer 3. Lack of Decision Making: A computer cannot decide on its own. Each operation that the computer performs is fed with an algorithm to perform different processes for each situation. However, if it faces a problem that is not fed into the system, the computer is not ready for it. It either gets corrupted or does not respond. 4. Lack of Common Sense: Despite the fact that computers are automated devices, they nevertheless need human intervention. Only when some input is given will it function. You might have to perform calculations for your math homework, for instance. Each sum must be fed in order to obtain the output. There are other characteristics of computers that make them lacking in some fields. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji

The Limitations of the Computer 5. Human dependency: Once turned on, a computer is a mechanism that operates entirely automatically. But it is unable to operate in order to turn on. Without such a program, the computer does not know when to start and when to stop. A computer has both its strengths and weaknesses, much like a coin has two sides. Humans have used computers for a very long time. However, they do contain restrictions that can only be removed with human aid. donjinobarrantes@gmail.com – 09551255191/09914964364 - \serdonji
