New products and systems can be developed to solve problems or to help do things that could not be done without the help of technology. For example, engines increase the speed at which people can travel, and pumps move water to locations where it is needed. The use of technology sometimes helps to improve personal lives by lessening threats, such as disease, toil, or ignorance. However, the desire or need for a new product or system can cause negative consequences, such as when people travel long hours to work in order to pay for improvements for their homes or child and healthcare.

Technology is closely linked to creativity, which has resulted in innovation. Most inventions are inspired by perceived needs and wants — the hairbrush, for example. Other inventions are linked to developing creative ideas and the way a person uses them, not necessarily their intended use. For example, the invention of the tea bag grew out of a packaging strategy to replace expensive tin containers. Although tea was packaged in small silk bags to give away as samples, some users thought it was a new way to brew the tea, and thus the tea bag was born. An invention can always be improved, and trying new ideas is often key to that improvement.

Apply a design process to solve problems in and beyond the laboratory-classroom. Perform research, then analyze and synthesize the resulting information gathered through the design process. Identify and select a need, want, or problem to solve, which could result in a solution that could lead to an invention (an original solution) or an innovation (a modification of an existing solution). Identify goals of the problem to be solved. These goals specify what the desired result should be.

Communication systems are made up of a source, encoder, transmitter, receiver, decoder, and destination. A communication system is similar to other systems in that it includes input, processes, outputs, and sometimes feedback. Information is encoded using symbols and graphics. To “encode” means to change the form of a message (as in pushing a key on a keyboard to produce a binary signal or changing a signal from analog to digital). Information must be decoded in order to be understood by the receiver. “Decoding” is the reverse of encoding, with data being converted back to symbols and graphics. Switching circuits allows signals to be sent back and forth in the communication process. A network is a system connected by communication lines to move information from one device to another. An example of a network is a local area network (LAN), which connects computers to a server. Computers are the primary tools used for networking information and communication technologies.
1.G
The development of technology is a human activity and is the result of individual or collective needs and the ability to be creative. Making products and systems through creativity and innovation. For example, from the time of the first gas cook stove in 1936 to the time of the microwave oven in 1967, the focus was on simplifying the process of cooking and reducing the time of food preparation.
6.F
Social and cultural priorities and values are reflected in technological devices. For example, an unenthusiastic attitude toward the use of genetically engineered foods has affected the development of this technology, yet many seed-producing companies are pressed to develop insect- and disease-resistant plants. Likewise, consumer tastes influence technological designs, such as the color and contours of household appliances. For example, new appliances are not marketed in the rounded shapes of the 1950s or the avocado green color of the 1970s.
