Computers are classified as mainframes (large and costly), mini computers (less powerful) and micro-computers (based on microchip technology). This classification is based on their power, speed of executing a set of instructions and the amount of memory available to store data as well as degree of inter connectivity that the computer offers.
Detailed Explanation
Computers can be categorized into three main types based on their specifications: mainframes, mini computers, and micro-computers. Mainframes are the largest and most expensive, used by large organizations for bulk data processing. Mini computers are smaller and less powerful, suitable for smaller businesses. Micro-computers, often referred to as personal computers, are based on microchip technology and are used for individual tasks. The classification largely depends on factors like processing power, speed, storage capacity, and interconnectivity options.
Examples & Analogies
Think of computers as different sizes of vehicles: mainframes are like trucks designed to carry heavy loads over long distances, mini computers are like vans that can carry a moderate amount, while micro-computers are like bicycles, perfect for individual travel.

The functions of micro-computer, particularly for extension work, include processing, keeping record of all kinds of information, performing accounting function, acting as repository of various cases, experiences to be used for research and field purpose in a very small space and publishing information material at reasonable cost. Computers can also communicate with each other if linked together and provide sourcing of information from across the globe.
Detailed Explanation
Micro-computers play an essential role in various tasks related to information management. They can process large amounts of data efficiently, maintain records, handle accounting tasks, and store diverse cases or experiences for research purposes. Because of their compact size, they are cost-effective solutions for businesses and individual users. Furthermore, when connected to a network, micro-computers can share information globally, which enhances collaboration and access to resources.
Examples & Analogies
Imagine a library where each book is a piece of information. Micro-computers act like librarians who keep track of every book, ensuring that if someone needs a certain topic, they can quickly find it, share it with others, and even add new books to their collection without needing a lot of space.
Bluetooth Technology

Bluetooth Technology is a low-cost, short-range radio frequency (RF) link between mobile PCs, mobile phones and other portable devices capable of transmitting voice and data at the rate of 1 Mbps, which is from three to eight times the average speed of parallel and serial ports, respectively. It allows wireless control of and communication between a cell phone and a hands-free headset or a car kit.
Detailed Explanation
Bluetooth technology creates a wireless connection between various electronic devices within short distances, commonly within 10 meters. It's commonly used to connect smartphones with hands-free devices, such as headsets and car kits, allowing users to communicate without physical wires. This technology operates at a speed of around 1 Megabit per second, significantly faster than older connection methods like parallel or serial ports.
Examples & Analogies
Imagine a DJ at a party using Bluetooth technology. The DJ can play music from their smartphone without being tied down by wires, letting them move around the dance floor freely while still controlling the music from a distance.
