  • 3. Redouane Boulguid, Safi/Morocco School-Year 2013-2014    In the mid-1970s, computers started getting small and inexpensive enough for people to have them in their homes. Many home computer users started using the network to communicate between computers and share messages with each other. You may wonder how computers talk to each other. In 1963, the American Standard Code for Information Interchange (ASCII) was developed. Different manufacturers use the same 128 codes to make the English alphabet, Arabic numerals, punctuation marks, and many other things. 3
  • 4. Redouane Boulguid, Safi/Morocco School-Year 2013-2014   During the last half of the 1970s, it was obvious that ARPANET wasn't big enough to handle all of this activity. The program was shifted to the National Science Foundation (NSF), which developed a larger network called the NSFNET. In 1990, this became known as the INTERNET. 4

  • 6. Redouane Boulguid, Safi/Morocco School-Year 2013-2014      How does an E. Mail travel? Email travels along imaginary roads from your computer to one or more servers and then to your friend's computer. Servers are the key to sending and receiving emails. You can think of servers like bridges. Some bridges are small carrying only a few cars. Other bridges are very large carrying many, many cars. If the bridge goes down, no traffic gets through. It's the same on the Internet, if a server goes down your email can't travel from your computer to your friend's computer. 6
  • 7. Redouane Boulguid, Safi/Morocco School-Year 2013-2014    So, What is a Computer? Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations. 7
  • 8. Redouane Boulguid, Safi/Morocco School-Year 2013-2014 A computer, then has four (4) functions: a. accepts data Input b. processes data Processing c. produces output Output d. stores results Storage  8
  • 9. Redouane Boulguid, Safi/Morocco School-Year 2013-2014   Input (Data): Input is the raw information entered into a computer from the input devices. It is the collection of letters, numbers, images etc. 9
  • 10. Redouane Boulguid, Safi/Morocco School-Year 2013-2014   Process: Process is the operation of data as per given instruction. It is totally internal process of the computer system. 10
  • 11. Redouane Boulguid, Safi/Morocco School-Year 2013-2014   Output: Output is the processed data given by computer after data processing. Output is also called as Result. We can save these results in the storage devices for the future use. 11
  • 12. Redouane Boulguid, Safi/Morocco School-Year 2013-2014 What are Computers for? Key Points to remember: 1. Computer is a device which converts DATA into INFORMATION; 2.
