 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 execution of  software is done in RAM. The operating system is loaded into RAM after computer boot and programs are loaded into RAM for execution. if the RAM size is small, it can significantly affect speed of your device, even browsing the internet and opening large documents. so our system should have at least 8GB of RAM.  Also check for extra slots, in case you would need to add more RAM in future. Normally we have 2 slots for RAM and they would be occupied by 4MB RAM slots.  





Storage: SSD or Hard Drive: A solid state drive or SSD is generally the preferred secondary storage medium for a laptop, since its much lighter and 3 to 4 times faster. But its life span is less than a hard drive and cost might be double or triple the HDD. A hard drive might be more suited for a desktop since the added weight is not a consideration. A HDD can afford large storage and good speed at lower cost than a Solid state drive. But the cost discrepancy between a HDD and SDD is coming down.

How a large secondary storage improves speed? How is virtual memory n paging done using hard disk.


The drives come in a capacity of 256 GB, 512 GB or 1024 GB or 1 TB and even more. 

Entry level users might not need more than 256 GB or 512 GB. 

Processor/Speed/Number of Cores:

The entry level computers are mostly dual core now which means two cores on a single chip.

Installing and Configuring Libreoffice SDK on Windows 11.

  What is Libreoffice SDK? Why do I need it. https://api.libreoffice.org/examples/examples.html#Cpp_examples Installing the SDK The instructions for installing the SDK are given in https://api.libreoffice.org/docs/install.html.  1) If you have the Libreoffice source code, you can install sdk with  --enable-odk option in autogen.input file . Then make check, make, ./autogen.sh. (https://wiki.documentfoundation.org/Development/lode). Now the SDK path will be c:/cygwin/home/$user/lode/dev/core/instdir/sdk 2. If you don't have the source code or don''t want to go through the build process again, then sdk can be installed from https://www.libreoffice.org/download/download-libreoffice/. In this case the sdk will be installed in C:\Program Files\LibreOffice\sdk. You will have to follow the path  cygwin/cygdrive/c/Program\ Files/Libreoffice/sdk/examples from cygwin shell.  The steps listed below are for installing the LibreOffice SDK Configuring the SDK in Libreoffice on windows 11

Accessing Internet on Fedora 10 using 3G Huawei USB broadband Modem from Nawras

Its been more than a month since i started to configure my Huawei modem for internet connectivity in Linux. Finally today i am logged in F10 and editing this post. 1. Firstly one has to check if the modem is being detected on the USB port. dmesg | grep USB should show entries for 2 or 3 USB ports. (ttyUSB0-ttyUSB2). My system shows 2 entries. Look the messages of following type: /***************************************************************************/ usb 4-3: GSM modem (1-port) converter now attached to ttyUSB1 scsi18 : SCSI emulation for USB Mass Storage devices usb 4-3: New USB device found, idVendor=12d1, idProduct=1003 usb 4-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 4-3: Product: HUAWEI Mobile usb 4-3: Manufacturer: HUAWEI Technologies usb-storage : device found at 6 /****************************************************************************/ The kernel should be able to identify the modem as a usb-storage device. If you have problems with this , workar

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 both. The software progr
