The Evolution of Computers, Software, and Web Design
From their humble beginning, computers have evolved significantly over time. Used for mathematical calculations initially, the first-generation computers designed in the 1940s and 1950s were very large and heavy. Fast-forward to today and computers are a fraction of their original size, possessing exceptional technological capabilities.
The first computers had very basic components, and they operated using a simple programming language. Operation of these machines produced significant internal heat, which often caused them to overheat. Gradual advancements led to the use of internal transistors instead of vacuum tubes, which generated less heat inside the machines. The size of the machines also became smaller during the second generation, and they became faster. Computers continued to shrink in size while they became faster during the third generation of the 1960s and into the early 1970s. Additional advancements included monitors and keyboards, which streamlined computer usage. Computers were also slowly becoming less expensive during this time. The fourth generation of computers is recognized as the time between 1971 and 2010. Monolithic integrated circuit technology enabled explosive advances in power and capabilities. Personal computers were introduced at the beginning of this generation, and by its close, they were the norm in the typical American household. This is also the generation that focused on smaller computer options, including laptops and even hand-held devices. Computers were much faster, stored much more data, and they were conveniently sized for portability. The fifth generation of computers is currently unfolding, and users can anticipate continued advancements in speed and capabilities.
Computer software has also advanced along with computers. Software involves the applications that work with the hardware components of the computer system to perform the processes. System software includes the operating system, utilities programs, and device drivers that are responsible for the basic computer operations. Application software includes programs such as word processing, spreadsheets, games, video editing, databases, and more. Software developers work continually to update and upgrade their software applications to expand their capabilities. Software advances to incorporate new technological processes, simplified tasks, and greater benefits to users.
