Transcript of CTSS CPA 3A3 _ Grace Tung
Because a production line has many steps, it requires a large number of people to support these steps. ~Reptitive boring work
Work in a production line is repetitive and tends to be boring. Automation can overcome these disadvantages. Automation occurs when machines are used to carry out or an activity with minimum human effect or supervision. In the later part of the 20th century, products became more complex and so did the production lines that produced them. Mechanical automation was no longer capable of doing many of the complex tasks. One common way to achieve automation is by using machines that contain embedded processors. Embedded processors are found on circuit boards of computerised machines. Such machines include computers and robot. A processor is a part of the computer that follows instructions and carries out actions. It is like the "brain" of a computer. Benefits of Using Robots. There are some advantages of using robots: Because robots work at fast speeds, products are made in a shorter time. So, with robots, productivity is high.
Because robots can accurate and consistent, consistency and quality of products can be ensured.
The cots of producing goods are reduced in the long run.
Workers do not have to be exposed to conditions that are dangerous or harmful to their health. Computers are being used to perform many functions that used to be done by people. An example is the job of the bank teller. In the past, when you want to deposit or withdraw money, the only way is to join the queue at the bank and interact with the human bank tellers behind the bank counter. Now, human bank tellers have been partially replaced by machines such as the automated teller machines (ATM). Although people still can choose to use the human bank teller on the ATM, most people choose the ATM as it is availble all day and the queue there is noramally short. Modern society is technologically advanced because of human creativity and innovation. Creativity and innovation requiredoing things diferently or seeing things from a different point of view. Currently computers are incapable of these because their 'knowledge' and rules are limited by the progras that they run on. So, humans and still more superior in being creative. 1.2 Publishing and Print Industries Publishing is the activity of putting information in the public arena (e.g. newpapers, magzined, books). Printing is a part of publishing. It is an industrial process for the production of text and images with ink on paper using press. 1. An author writes his/her manuscripts using a word processor. 2. A graphic artist creates illustrations using a graphics program. 3. An editor checks for mistakes and makes changes using word processor. 4. A typesetter arranges the text and graphics using a desktop publisher. 5. If it is a full-colour publication, the desktop publication, the desktop publisher separated the images into 4 colours. 4 sets of black-and-white films, each corresponding to a colour, are produced, 6. Each film is placed onto a zinc plate. Ultraviolet light is shone onto the film and plate, producing a positive image on the plate. 4 sets of printing plates are formed. 7. The plates are arranged carefully in a printing machines that is controlled by a computer. The final printed product is a combination of the coloured images from all 4 plates.
