Main article: History of computer science Charles Babbage is credited with inventing the first mechanical computer. Ada Lovelace is credited with writing the first algorithm intended for processing on a computer. The earliest foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks such as the abacus have existed since antiquity‚ aiding in computations such as multiplication and

Computers are one of the most important inventions ever. If computers had not been invented‚ technology would not be developed to its current state. Since the computers invention‚ society has changed drastically. Computer technology is so helpful‚ that it is even used to create newer‚ better computer equipment. Almost everything today is linked in some way‚ to computers. Before computers were invented‚ very little was known about outer space. With the technology we have now‚ we are learning

How Do Computers Affect Our Work? Accuracy and Efficiency Computers house powerful software and other applications that ensure accuracy at work. Instead of calculating numbers manually or making projections that involve formulas by hand‚ you can use your computer to derive the answer. This limits the possibility of human error mistakes‚ such as inputting numbers incorrectly. Also‚ when typing documents or communication‚ most computers are equipped with word processors that fix grammar and spelling

What Is a Product Mix? Product mix‚ also known as product assortment‚ refers to the total number of product lines that a company offers to its customers. For example‚ a small company may sell multiple lines of products. Sometimes‚ these product lines are fairly similar‚ such as dish washing liquid and bar soap‚ which are used for cleaning and use similar technologies. Other times‚ the product lines are vastly different‚ such as diapers and razors. The four dimensions to a company’s product mix include
