Importance of computer literacy

  1. 1. Importance of Computer Literacy Computer Literacy is the knowledge and understandingcomputer concepts, limitations and ability to usecomputers and technology efficiently. Computer Literacycan also refer to the comfort level someone has with usingcomputer programs and other applications that areassociated with computers.Prepared By: Joanne Marie A. Urbano Presented to: Mr. Rodolfo Raborar
  2. 2. What is Computer? Computer is a electronic device capable of interpreting and executing programmed commands for input, output, computation and logic operations.Advantages of Computer1.Speed2.Repettiveness3.Accuracy4.Stores and Retrieve Information5.Logic Operations6.Self-Operating
  3. 3.  Speed- A computer can process data faster than other machine. Designed to perform similar task. Repetitiveness- A computer can easily perform same operations millions of times in exactly the same way method. Accuracy- A computer is accompanied by light accuracy result Stores and Retrieve information- A computer is like a human brain because it can store data, acts instructions and retrieve information.
  4. 4.  Logic Operations- A computer can perform operations based on alternative courses of Action. Self- Operating- Once data and Instructions are into the computer memory, the computer is capable of executing the instructions without human intervention.
  5. 5. Disadvantages of Computer 1. It cannot correct wrong instructions 2.Prone to machine Defection 3. It cannot interpret objectELEMENTS OF COMPUTING PROCESS1. Hardware2. Software3. Data4. People5. Procedures6. Connectivity
  6. 6.  Hardware- This are the physical devices that comprised a computer system. Example are monitor, keyboard and printer. Software- a set of instructions called programs, Example are Ms Word and Ms Excel. Data- are inputs for processing, Example are name, address, and Tel.No. People- provide the inputs and the use. The computer output also called users/end- users. Procedures-The steps to be followed to accomplish a specific tasks. Connectivity-An electronic connections and communication between computer system.
  7. 7. Computer Uses Computers are just as common as pen and paper for writing, especially among youth. For many applications - especially communicating- computers are preferred over pen, paper, and typewriters because of their ability to duplicate and retain information and ease of editing. As personal computers become common place and they become more powerful , the concept of computer literacy is moving beyond basic functionality to more powerful applications under the heading of literacy.
  8. 8.  Of course, arguments about computers being common - place in the first world has equal access to the latest forms of technology. however, there is a pronounced digital divide that separates both physical access to technology and the ability to use that technology effectively. Where computers are widespread, they are also a part of education. Computers are used in schools for many applications such as writing papers or searching the Internet information. Computer skills are also a subject being specifically taught in many schools, especially from adolescence onward - when the ability to make abstractions forms.

  10. 10. Importance of Computer LiteracyThe precise definition of "computer literacy" can very from group to group. Generally, literate (in the realm of books) connotes one who can read any arbitrary book in their native language [s], looking up new words as they are exposed to them. Likewise, an experienced computer professional may consider the ability to self - tech (i.e. to learn arbitrary new programs or tasks as they are encountered) to be central to computer literacy. In common discourse, however," computer literacy" often connotes little more than the ability to use several very specific applications (usually Microsoft word, Microsoft Internet Explorer, and Microsoft Outlook) for certain very
  11. 11. well - defined simple tasks, largely by rote. (This is analogous to a child claiming that they "can read" they have rote - memorized several small childrens books. Real problems can arise when such a "Computer Literate" person encounters a new program for the first time, and large degrees of "hand holding " will likely be required.) Being "literate" and "functional" are generally taken to mean the same thing. The pervasiveness of computers continues to grow at an outstanding rate. Computers always change; they become smaller, faster and more powerful. These changes have motivated the modern society to become comfortable with basic computer - related skills.
  12. 12.  The level of computer literacy one must achieve to gain an advantage over others depends both on the society one is in and ones place in the social hierarchy. Prior to the development of the first computers in the b1950s, the word computer referred to a person who could count, calculate, compute. The fear of some educators today is that computer training in schools will serve only to train data-entry clerks of the next generation, low level workers of the so called knowledge industries. On the other hand, some hope that enhanced computer literacy will
  13. 13.  enable a new generation of cultural producers to make meanings and circulate those in the public sphere. The wildfire of cultural production associated with sites such as Youtube seems to support this notion. Different countries have different needs for computer literate people due to their society standards and level of technology . The worlds digital divide is now an uneven one with knowledge nodes such as India disrupting old North/South dichotomies of knowledge and power.
  14. 14.  Computer Literacy is considered to be a very important skill to possess while in the first world. Employers want their workers to have basic computer skills because their company becomes ever more dependent on computers. Many companies try to use computers to help run their company faster and cheaper.
  15. 15. Computer Competency Having some skill in a computer so that you can use it to meet your information needs and improve your productivity. The user feel comfortable using and operating a computer Understand the impact of Computers on society , now and in the future Be an intelligent consumer of computer and other computer equipments collectively called hardware. Be an intelligent consumer of computer related products and services.
  16. 16. Categories of Computer Personal Computer/Microcomputer Workstation Midsize mainframe Mainframe Super Computer
  17. 17.  Personal Computer- A small computer designed for use by an individual. Workstation- a high performance single-user computer with sophisticated input/output devices that can be easily networked with other workstation computer. Midsize mainframe- a midlevel computer built to perform complex computation while dealing efficiently with a high level input/output from users via terminal. Mainframe- a high level computer designed for the most intensive computational tasks. Supercomputer- A large extremely fast and expensive computer used for complex or sophisticated calculation.
