2.2. ప్రారంభ సెటప్ దశలు
- Prepare the MicroSD Card: Install the operating system (e.g., Raspberry Pi OS) onto a MicroSD card. A minimum of 8GB is recommended, but 16GB or 32GB provides more flexibility. Use a reliable imaging tool like Raspberry Pi Imager.
- మైక్రో SD కార్డ్ని చొప్పించండి: Locate the MicroSD card slot on the underside of the Raspberry Pi board and gently insert the prepared card until it clicks into place.
- పెరిఫెరల్స్ కనెక్ట్ చేయండి:
- ప్రదర్శన: Connect one or two micro HDMI cables from the Raspberry Pi to your monitor(s). The Raspberry Pi 4 supports dual 4K displays.
- కీబోర్డ్ మరియు మౌస్: Plug your USB keyboard and mouse into the available USB 2.0 or USB 3.0 ports.
- నెట్వర్క్: For wired internet, connect an Ethernet cable to the Gigabit Ethernet port. For wireless, ensure your Wi-Fi network is available during OS setup.
- పవర్ కనెక్ట్ చేయండి: Plug a 5V 3.0A USB-C power supply into the USB-C power input connector. The Raspberry Pi 4 will automatically power on once connected.
- మొదటి బూట్: The Raspberry Pi will boot up and guide you through the initial setup process, including setting your locale, Wi-Fi, and password.
3. Operating Your Raspberry Pi 4
Once set up, your Raspberry Pi 4 Model B is ready for use. It runs on Raspberry Pi OS (formerly Raspbian), a Debian-based operating system optimized for the Pi hardware.
3.1. Key Features and Performance
- శక్తివంతమైన CPU: Equipped with the latest ARM Cortex-A72 architecture, clocked at 1.5GHz, providing significant performance improvements for general computing tasks.
- Video Output/GPU: The on-board GPU supports 4Kp60 video decoding (H.265) and OpenGL ES 3.0, enabling smooth multimedia playback and graphical applications. Dual micro HDMI ports allow for multi-monitor setups.
- USB 3.0: Two USB 3.0 ports offer faster data transfer speeds compared to previous models, ideal for external storage or high-bandwidth peripherals. Two USB 2.0 ports are also available.
- Network & Bluetooth: Features Gigabit Ethernet for high-speed wired networking and Bluetooth 5.0 for improved wireless connectivity and transfer speeds.
3.2. Software and Applications
Raspberry Pi OS comes pre-installed with a variety of software, including a web browser, office suite, programming tools, and educational applications. You can install additional software using the 'Add/Remove Software' utility or via the command line using apt ఆదేశాలు.
4. నిర్వహణ
Proper maintenance ensures the longevity and optimal performance of your Raspberry Pi 4.
- శీతలీకరణ: The Raspberry Pi 4 can generate heat under heavy load. Consider using a case with passive cooling (heat sinks) or active cooling (fan) to prevent thermal throttling and ensure stable operation.
- విద్యుత్ సరఫరా: Always use a stable 5V 3.0A USB-C power supply. Insufficient power can lead to instability or data corruption.
- సాఫ్ట్వేర్ అప్డేట్లు: Regularly update your Raspberry Pi OS to ensure you have the latest features, security patches, and bug fixes. Use
sudo apt updateమరియుsudo apt full-upgradeటెర్మినల్ లో. - సురక్షిత షట్డౌన్: Always shut down your Raspberry Pi properly through the operating system (e.g., via the desktop menu or
sudo shutdown nowcommand) before disconnecting power to prevent SD card corruption. - భౌతిక పర్యావరణం: Keep the board in a clean, dry environment, away from dust, moisture, and extreme temperatures.
