This picture shows one of the world's first computers, and two of the world's first computer programmers. What are three ways this computer is different from computers that we use today? What are two ways that it is the same? What is one thing you think is true of ALL computers?
Three ways this computer is different from computers we use today are:
1) Size: The computer shown in the picture is massive and takes up an entire room, whereas today's computers are significantly smaller and can fit on a desk or even in our pockets.
2) Processing power: The computer in the picture has much lower processing power compared to modern computers. It could perform calculations at a much slower rate and had limited memory capacity.
3) Input and output methods: The computer in the picture used punch cards as a means of input and a printer as a means of output. Modern computers, on the other hand, use keyboards, mice, touchscreens, and have a variety of output options such as monitors and speakers.
Two ways that this computer is similar to computers we use today are:
1) Function: The computer in the picture was designed to perform calculations and process data, just like modern computers. While the capabilities and speed have significantly improved, the fundamental purpose remains the same.
2) Use of programming: The computer in the picture required programming to operate, and Ada Lovelace and Charles Babbage, the two individuals in the picture, were the world's first computer programmers. Similarly, today's computers also rely on programming to execute tasks and algorithms.
One thing that is true of all computers is that they process and manipulate data in some form. Computers take in input, perform operations on that input, and produce output based on those operations.
