Module 1.1

Notes

Module 1.1: Computers in Everyday Life This module introduces fundamental concepts about computers, their uses, user categories, and emerging technologies. • Why Computers are Used: Computers enhance efficiency, accuracy, and reliability, saving time, labor, and resources while enabling global communication. • Comparing Devices: Selecting a device (smartphone, laptop, desktop) depends on factors like power, purpose, size, and software needs. For example, gaming requires a strong CPU, ample RAM, a large screen, and specific software. • Computer Types: ◦ Non-portable computers (e.g., desktops, servers) are large, more powerful, and not meant to be moved. They are harder to fix and upgrade than portable devices. ◦ Entry-level computers are the most affordable, with lower hardware specs (slower CPU, less RAM) and often home editions of OS. ◦ Portable computers (laptops, tablets, smartphones) are all-in-one, easy to carry, and protect internal parts. However, they are less modular; components like CPU or graphics card are not easily replaceable or upgradeable, unlike desktops. • Modular Design: Computers are built in parts, allowing upgrades or replacemen...
