Overview Computers A computer is a machine that manipulates data according to a set of instructions.datainstructions Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs)PCs 2

Overview Computers (Continued) Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.integrated circuits 3

Overview Computers (Continued) [ 4 Simple computers are small enough to fit into a wristwatch, and can be powered by a watch battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". The embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are however the most numerous. wristwatchwatch batteryPersonal computersiconsInformation Age embedded computersMP3 playersfighter aircraft toysindustrial robots

Overview Computers (Continued) 5 The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore computers ranging from a mobile phone to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity.programs calculatorsmobile phone supercomputer

9 Spreadsheets A spreadsheet is a computer application thatcomputer application simulates a paper worksheet. It displays multiple cells that together make up a grid consisting of rows and columns, each cell containing either alphanumeric text or numeric values. A spreadsheet cell may alternatively contain a formula that defines how the contents of that cell is to be calculated from the contents of any other cell (or combination of cells) each time any cell is updated. Spreadsheets are frequently used for financial information because of their ability to re-calculate the entire sheet automatically after a change to a single cell is made.worksheet alphanumeric formulafinancial
