The main types of computer are supercomputers, mainframes, personal computers, laptops, netbooks, tablets and smartphones. Each have different purposes and capabilities.
Supercomputers have huge data storage capacities and unrivaled processing power. They are used by large organizations that require immense computing power. These computers are exceptionally expensive and very delicate. Housed in clean rooms, supercomputers must be kept free of dust and debris, and have to be constantly cooled because of the heat they generate.
Mainframe computers have considerably less power and capacity than supercomputers, but significantly more than personal computers. They are capable of processing billions of instructions per second and handle vast quantities of data simultaneously.
Personal computers are common in homes and offices throughout the world. Modern models have large storage capacities and run multiple applications simultaneously.
Modern laptops feature similar specifications to desktop computers, with the added bonus of being portable. However, laptops can feel heavy and battery life can be an issue if needing to work for long periods without being able to recharge.
Netbooks are smaller and lighter than laptops, but have considerably less storage capacity and power. However, their small size and minimal weight makes them attractive for browsing the web, checking emails and creating documents when not in the office.
Tablets and smartphones are similar in nature and operate on a touchscreen basis. They are user-friendly, lightweight and very convenient, being popular with people of all ages and backgrounds.
