Abacus:

• An abacus is a manual device used for calculations. It’s one of the oldest calculating tools known to humans, dating back thousands of years.

• It uses a series of rods or wires with beads that can be slid back and forth for counting.

• The abacus is great for basic arithmetic operations like addition, subtraction, multiplication, and division.

• It doesn’t require electricity to operate and is portable.

• However, it’s not suitable for complex calculations or storing large amounts of data.

Modern-Day Computer:

• A computer is an electronic device that can perform complex calculations at incredibly high speeds.

• It can do much more than just arithmetic. It can run software applications, connect to the internet, play music and videos, and much more.

• Computers have a large storage capacity for data and can process multiple tasks at the same time.

• They require electricity to operate and, while some are portable (like laptops), others are not (like desktops).

• Computers can also be programmed to automate tasks, something an abacus can’t do.

In summary, while an abacus and a computer can both be used for calculations, a computer is much more versatile and powerful. However, the simplicity and durability of an abacus still make it a useful tool, especially for teaching basic arithmetic.
