Week 1-2: Introduction to Computers (Day I)

Computer Hardware Components: Learn about the essential hardware components of a computer, including the CPU (Central Processing Unit), RAM (Random Access Memory), storage devices (HDD, SSD), and various input/output devices (keyboard, mouse, monitor).

Of course! Here's a more detailed breakdown of computer hardware components: 1. **CPU (Central Processing Unit):**

- The CPU is often considered the brain of the computer, responsible for executing instructions and performing calculations. - It consists of an arithmetic logic unit (ALU) for mathematical operations and a control unit for managing the execution of instructions. - CPUs come in various types and speeds, with multicore processors being common today, allowing computers to perform multiple tasks simultaneously.

2. **RAM (Random Access Memory):**

- RAM is a type of volatile memory used by the computer to temporarily store data that is actively being used or processed. - Unlike storage devices, such as hard drives or SSDs, RAM is much faster but loses its data when the computer is powered off. - More RAM allows a computer to run more programs simultaneously and handle larger datasets more efficiently.

3. **Storage Devices:**

- Storage devices, like hard disk drives (HDDs) and solid-state drives (SSDs), are used to store data persistently even when the computer is turned off. - HDDs use spinning magnetic disks to store data, while SSDs use flash memory chips for faster access times and better durability. - Storage capacity is measured in gigabytes (GB) or terabytes (TB), with SSDs generally offering faster read/write speeds but being more expensive per unit of storage than HDDs.

4. **Input/Output Devices:**

- Input devices allow users to input data and commands into the computer. Common examples include keyboards, mice, touchpads, and scanners. - Output devices display the results of computations or actions performed by the computer. Examples include monitors, printers, speakers, and projectors. - Input/output devices facilitate communication between the user and the computer, enabling interaction and information exchange.

Understanding these hardware components provides a foundational knowledge of how computers function and allows users to make informed decisions when selecting or configuring computer systems.
