The Open Source Journey

 What to consider while buying a laptop/desktop Between a laptop and Desktop If you need moblility with your device then laptop is the way to go, otherwise a desktop is suited as a standalone device in a dedicated work room.  If my requirement is limited to creating documents, like word, excel, or using the internet for educational or entertainment , then entry level system will be sufficient. If i need to install and develop heavier software applications or for faster gaming experiences then i5 might be the right choice. For video content creation probably i7 would suffice.   AMD or intel: In intel i3 is the entry level processor range (normally dualcore). (what does 11th-13th Gen??). i5 and i7 is mid range and i9 for high end users. in AMD?? Which model:  Budget and Requirement: The entry level system would fall between RAM/Memory : Explain what is RAM? and Why it matters. Random access memory is like the brain(frontal lobe precisely) of the computer. All exe...

Intel Core Multi core line of processors introduced around 2006. Replaced the Pentium line of processors. The line up of intel core processors includes low end-i3 (entry level consumer), mid end-i5 (mainstream consumer), high end-i7  and enthusiast-i9. Xeon refers to workstation and server brands. Instead, its better to differentiate generation by technical features. For example, intel core i7 of 12th, 13th and 14th generation differ in base speed, number of performance and efficiency cores,  cache size and micro-architecture technology.  This naming scheme was introduced in 2008 and does not correspond to specific technical features like  number of cores in a processor.  What is multi core processor? A multi core processor is a processor on a single Integrated circuit with two or more execution units called cores. So the processing tasks can be executed in parallel on the separate cores. It might involve data parallelism or task parallelism or hybrid involving ...

  UEFI: Universal Extensible firmware interface  https://en.wikipedia.org/wiki/UEFI UEFI does not depend on boot sectors unlike PC BIOS. It defines a boot manager as part of the UEFI specification.       The boot configuration is defined by variables stored in NVRAM including the variables that define file system paths to OS loaders and OS kernels.  ON power on, Based on it, the boot manager runs the specified boot loaders or kernel. The file path varies depending on the computer architecture.The file path to OS loader might be efi\boot\bootx64.efi.(edit) Booting UEFI systems from GPT partitioned disks is called UEFI-GPT booting. EFI system partition is normaly the first partition in the disk. It requires a size of around 100 MB. I t is accessed by UEFI firmware when the computer is powered on. It stores UEFI applications and OS boot loaders. it is formatted using a specific FAT file system for UEFI   .   UEFI shell and its usage https://ww...
