Spectrum management Light, colors, AM and FM radio, and electronic devices make use of the electromagnetic spectrum. This determines which frequency ranges can be used for what purpose and by whom. They can be used within range of the mobile telephone site used to house the equipment required to transmit and receive the radio signals from these instruments.

Library expansion[ edit ] Library expansion was calculated in by Fremont Rider to double in capacity every 16 years, if sufficient space were made available.
He did not foresee the digital technology that would follow decades later to replace analog microform with digital imaging, storage, and transmission media. Automated, potentially lossless digital technologies allowed vast increases in the rapidity of information growth. Connectivity between computers within companies led to the ability of workers at different levels to access greater amounts of information.
In terms of capacity, there are two measures of importance: Microcomputers were developed and many businesses and industries were greatly changed by ICT.
In essence, a copy of a product made of bits can be made cheaply and quickly, and shipped across the country or internationally quickly and at very low cost.

Unsourced material may be challenged and removed. October Learn how and when to remove this template message The Information Age has affected the workforce in several ways.
It has created a situation in which workers who perform easily automated tasks are forced to find work that is not easily automated.
Lastly, workers are being replaced by computers that can do their jobs faster and more effectively. This poses problems for workers in industrial societies, which are still to be solved. However, solutions that involve lowering the working time are usually highly resisted.
Individuals who lose their jobs must either move up, joining a group of "mind workers" engineers, doctors, attorneys, teachers, scientists, professors, executives, journalists, consultantsor settle for low-skill, low-wage service jobs.
The "mind workers" are able to compete successfully in the world market and receive relatively high wages.
Conversely, production workers and service workers in industrialized nations are unable to compete with workers in developing countries and either lose their jobs through outsourcing or are forced to accept wage cuts.
This has had several major consequences, including increased opportunity in developing countries and the globalisation of the workforce. Workers in developing countries have a competitive advantage that translates into increased opportunities and higher wages.
In the past, the economic fate of workers was tied to the fate of national economies. For example, workers in the United States were once well paid in comparison to the workers in other countries. With the advent of the Information Age and improvements in communication, this is no longer the case.
Because workers are forced to compete in a global job marketwages are less dependent on the success or failure of individual economies.
This pattern of decrease in jobs continued until This trend has important implications for the workforce; workers are becoming increasingly productive as the value of their labor decreases.
However, there are also important implications for capitalism itself; not only is the value of labor decreased, the value of capital is also diminished. In the classical model, investments in human capital and financial capital are important predictors of the performance of a new venture.
History of computers Before the advent of electronicsmechanical computerslike the Analytical Engine inwere designed to provide routine mathematical calculation and simple decision-making capabilities.
The invention of the transistor in enabled the era of mainframe computers s — stypified by the IBM These large, room-sized computers provided data calculation and manipulation that was much faster than humanly possible, but were expensive to buy and maintain, so were initially limited to a few scientific institutions, large corporations, and government agencies.
As transistor technology rapidly improvedthe ratio of computing power to size increased dramatically, giving direct access to computers to ever smaller groups of people.
Along with electronic arcade machines and home video game consoles in the s, the development of personal computers like the Commodore PET and Apple II both in gave individuals access to the computer. But data sharing between individual computers was either non-existent or largely manualat first using punched cards and magnetic tapeand later floppy disks.
History of telecommunications The first developments for storing data were initially based on photographs, starting with microphotography in and then microform in the s, with the ability to store documents on film, making them much more compact.
In the s, electronic paper allowed digital information appear as paper documents.Cables are disappearing. Communication between components uses short-distance wireless technology. High-speed wireless communication provides access to the Web. The majority of text is created using continuous speech recognition.
Also ubiquitous are language user interfaces (LUIs). The wireless era Telecommunication is defined by the International Telecommunication Union (ITU) as the transmission, emission or reception of any signs, signals or messages by electromagnetic systems.
The Information Age (also known as the Computer Age, Digital Age, or New Media Age) is a historic period in the 21st century characterized by the rapid shift from traditional industry that the Industrial Revolution brought through industrialization, to an economy based on information technology.
The onset of the Information Age is associated with . Wireless technology allows entrepreneurs to grow their businesses without any hassles. Owing to the flexibility of the wireless network, users can be added easily. Therefore, office restructuring, shifts or expansion can be managed easily.
