Computers and
productivity 1.1 Embedded Processors and Automation This is Henry Ford Mass production is the manufacture
of large amounts of standardised products
on production lines. It was popularised by Henry in the early 20th century. Mass production became popular because it enables goods to be produced on a large scale at a low price.Mass production made Ford's car (Model T) affordable to many people.

Repetitive boring work Requires a large workforce Automation occurs when machines are used
tob carry out a process or an activity with
minimum human effort or supervision. 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 are accurate and consistent, consistency and quality of products can
be ensured. The costs 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. 1.2 Publishing ang Print Industries Publishing is the activity of putting
information in the public arena
(e.g. newspapers, magazines, books).
Printing is part of publishing. It is an industrial
process for the production of text and images
with ink on paper using a printing press. Benefits of Using Computers in publishing Graphics can be changed more easily than before. (In the past, graphics are drawn on paper. Once inked, it is difficult to correct.) The spelling-and-grammar checker in word processors helps to reduce mistakes in manuscripts. In the past, layout was done manually (i.e. cutting and pasting). A desktop publisher considerably improves productivity in doing layout. Previously, cameras with colour filters were used to take pictures of the text, illustrations and photographs. The components of the colour images were then recorded onto black-and-white films from which printing plates were made.The use of high-resolution machines called image-setters improves productivity in producing films.
Modern printing machines are controlled by computers. They can adjust the print positions and colour, ensuring a high-quality product. Computer to Plate (CTP) Computer-to-Plate (CTP) is a type of printing process which skips the film-producing step. In this method, the digital image, which is also in the CMYK format, is transmitted directly from the computer to a plate. Benefits of CTP 1. CTP technology saves money and time in producing films and shooting plates from films. This increases productivity. 2. Without having to arrange the films to shoot plates, it reduces the risk of human error. 1.3 Postal Mail Sorting Benefits of Using Computers in Postal Mail Sorting Less manpower is used because of the used of computerised machines. This shortens the time taken to process mail and so the envelopes reach their destinations earlier. Sorting envelopes manually requires a lot of manpower and is time consuming. Also, more mistakes may occur. 1.4 Computers at the Airport Airports are important hubs for travel. Improvements in aircraft technology mean that more and more people are travelling by plane. As the volume of air traffic increased, computer were slowly roped in to perform some of the repetitive tasks and, subsequently, some of the more sophisticated tasks. Designing Airports Computers can be used for designing airports. For example, using computers, different designs can be simulated on a computer to test their effectiveness. Using simulations can help take the 'guesswork' out of designing an airport. Advantages of Customer Database Saves time Storing the customer's information in a database allows this information to be retrieved or updated very easily and quickly. Data mining Data mining refers to extracting information from data. This information helps to reveal hidden patterns in the data that can be used to predict the future. Disadvantages of Customer Database Cost The equipment and software to support a customer database
may be expensive.
Cost of failure Storing the information in a customer database may lead to
a high cost of failure when the database is down. 1.6 The Home of the Future Many household appliances are controlled by embedded microprocessors.
These are special-purpose computers because the programs in them are
written to do specific kinds of work. Movies, music, games Personal productivity Homework, project work Creativity Editing your digital photos, slideshows All these can be done easily. For example, you can store your photos, music
and home videos in one place. 1.7 Impact of Computers on society 1. Repectitive Work
2.In Harsh Environments
3.With No Rest
4.Hard Labour Things that Human Beings are Good at Doing 1. Creative Work
2. Pattern Recognition
4.Dealing with Uncertainty 1.8 Artificial Intelligence AI is used to describe attempts at making machines as intelligent as or more intelligent than people. Applications of AI AI is an attractive science because it has a wide range of applications. AI can found in robots AI used in aircraft
