Ms. Mary Jade C. Jakosalem, LPT, MBA COMPUTERS AN INTRODUCTION  WHERE DID THE TERM ‘COMPUTER’COME FROM? In 1640, the term ‘computer’ was initially referred to as “one who calculates”. In 1897, it was called the “Calculating Machine”. A calculating machine is a machine for performing arithmetical operations that are usually more complex that can be done on adding machine, or calculator. In 1945, it was indicated as “programmable digital electronic computer” which is now called a computer. WHAT IS A COMPUTER? It is a programmable electronic machine designed to take input, perform prescribed arithmetic and logical operations at fast speeds, and provide the output of these operations. COMPUTER is an acronym for “Common Operating Machine Purposely Used for Technological and Educational Research”. It is derived from the Latin word “computare” which means to calculate, to count, to sum up. Basically, computer is a device that performs computation. CHARLES BABBAGE known as the Father of Computers. designed the first mechanical computer in 1837. It was called the “Analytical Engine” and was the first general-purpose computer. BASIC FUNCTIONS OF A COMPUTER  USES OF A COMPUTER can store important data. can communicate with people around the world. used for the educational system. used for office works like data entry, support, development, etc. used in banking, finance, and marketing. used in government sectors. used in sports. used for press and publishing. used for entertainment. CLASSIFICATION OF COMPUTERS ADVANTAGES & DISADVANTAGES OF COMPUTERS ADVANTAGES DISADVANTAGES Amazing speed Unemployment Health Issues Accuracy Cyber Crimes Huge Storage Virus and Hacking Attacks Multitasking Support Improper Use Data Security Spread of False or Automation Inappropriate Content Negative Impact on the Reduced Cost Environment COMPUTER COMPUTER HARDWARE SOFTWARE A group of programming Physical components or instructions designed to parts that jointly form a instruct the computer to computer system. perform specific tasks.
