ET/ICT/25/0089::A Beginner’s Guide to Computer Hardware

Computer hardware refers to the physical components of a computer system. These are the parts you can touch and see, and they work together with software to make the computer function. Hardware is divided into internal components (inside the case) and external components (connected outside). Parts of Computer Hardware Central Processing Unit (CPU) The CPU is the brain of the computer. It performs all calculations, executes instructions, and controls the overall functioning of the system. Modern CPUs have multiple cores, which allow them to handle several tasks at the same time, making the computer faster and more efficient. The Central Processing Unit (CPU) The Motherboard The motherboard is the main circuit board. It connects the CPU, RAM, storage devices, and other components, allowing them to communicate. It also contains buses and chipsets that manage data flow between different parts of the computer. The Mother Board Memory (RAM) RAM is temporary storage used while the com...

Cloud Computing: The Future of ICT for Students ET/ICT/25/0115

Cloud computing is simply the idea of storing and accessing data or applications over the internet instead of relying on your computer’s hard drive. Every time you use Google Drive, Dropbox, or iCloud, you’re already experiencing cloud computing in action. It allows you to reach your files anytime, anywhere, as long as you have internet access. The beauty of cloud computing lies in its flexibility. You don’t need expensive hardware because the cloud provides storage and services on demand. It scales easily, meaning you can expand your usage whenever you need more space. Collaboration becomes effortless since multiple people can work on the same document in real time, making group projects smoother and faster. There are three main types of cloud services. Infrastructure as a Service (IaaS) lets you rent servers and storage, with platforms like AWS and Azure leading the way. Platform as a Service (PaaS) provides tools for developers to build applications, such as Google App Engine. Softw...

EVANS KABIE COMPUTER BATTERY ET/ICT/25/0059

COMPUTER BATTERY A battery is a hardware component that supplies power to a device, enabling it to work without a power cord. It converts stored chemical energy into electrical energy through chemical reactions and transfers it to a circuit. Batteries can power a laptop for several hours depending on how much power the system requires. How Batteries Work Batteries generate electrical energy through internal chemical reactions. As long as the chemical materials inside can continue reacting, electricity is produced. Once the chemical resources are depleted, the battery runs out of power. Rechargeable batteries allow the reaction to be reversed by applying electrical current. Though more expensive, they can be reused many times through charge‑discharge cycles, offering a longer lifespan. The Three Types of Computer Batteries CMOS Battery (Backup Battery) — This small coin‑sized battery holds your computer’s settings such as time and date. Without it, you’d have to reset these each time t...
