  • Build A Computer A Comprehensive Step By Step Guide

    Computer System

    The Computer System is a very vast subject with lots of varieties. Any configuration of computing hardwares along with its associated softwares can be termed as a Computer System. There are different combinations being used in today’s world, here we will discuss “Personal Computer” 

    Personal Computer 

    These are a category of computing system generally used in home, schools and offices for personal use or in other words for low computing requirements like office use or for day to day tasks. 

    Build A Personal Computer

    You can buy a Preconfigured ready to use PC or build a PC as per your requirements 

    Step1: Choose your PC Hardwares.

    Step 2: Hardware installation.

    Step 3: BIOS Settings and OS installation. 

    Step 1

    Choose your PC Hardwares.

    First of all decide what type of PC you need (for personal use, for gaming purpose or development purpose)

    Here we will discuss building a gaming PC

    Main parts of gaming computer are:

    Motherboard This is a PCB where all our computer parts will be installed like CPU, GPU, RAM, Storage device, cooling systems etc.

    While selecting MotherBoard you have to be very cautious as this selection will affect all others, that is why I am discussing this part in the beginning.There are various specifications to look after while selecting Motherboards. Here we will discuss them in brief-

    • Form Factor : MotherBoard comes in different form factors ATX (Full size motherboard), Micro ATX and mini ITX. ATX MotherBoards are widely used so they have a great support, these motherboards will give you most modifications and updating support.
    • CPU Support: while selecting your system board you must do some research on what type of CPU it supports like Intel Or AMD, version of CPU and  generation of CPU.
    • Memory Support : Take a note of Memory type support,Max memory (GB), speed, Dual Channel or Single channel and number of DIMM slots.
    • Storage Device : Look For HDD and SSD support, Drive Form Factor, Type of Connector.
    • Expansion Slots: While selection of motherboard keep in mind the number of PCI Slots available and the number of slots you need or will need for future upgradation.
    • Connectivity: Look for connection  support of your board, like available LAN cards, availability of WiFi and Bluetooth and their version.

    CPU (Central Processing Unit) is the brain of any computer system. This performs all arithmetic and logical operations.

    There are mainly two CPU manufacturers in the market, AMD and Intel.

    Both Intel and AMD have many processor lines with different generations, while selecting a CPU you must look for its no. of cores, no. of threads, cache, memory support, and thermal solution required. Last few years releases are listed below:

    Intel

    Intel® Core™ i3 Processors 

    Intel® Core™ i5 Processors 

    Intel® Core™ i7 Processors 

    Intel® Core™ i9 Processors 

    Intel® Core™ X-Series Processors 

    AMD 

    AMD Ryzen™ 9 Desktop Processors

    AMD Ryzen™ 7 Desktop Processors

    AMD Ryzen™ 5 Desktop Processors

    AMD Ryzen™ 3 Desktop Processors

    AMD Ryzen™ Threadripper™ Processors

    CPU Cooler : As the CPU is the brain of a computer system and performs various tasks it also generates a lot of heat and so it requires an effective cooling system. You should choose the CPU Cooling system Depending upon the type of CPU and its heat dissipation capacity. Most of the CPU comes with coolers  from the manufacturers (Stock coolers), stock coolers are good for normal performance but to get better performance without throttling down your CPU capabilities you must choose liquid coolers with big thermal radiators.

    GPU (Graphics Processing Unit): Main task of the GPU is processing graphical Data. This is mainly used for Gaming, graphics designing, in processing AI data and nowadays it is also used for mining crypto currencies. If you are configuring a gaming computer you should choose your Graphic card wisely since nowadays modern games are made of high graphics.

    The name GPU and graphic card are used interchangeably but they both are not same they are different in some ways. A GPU is a chip like CPU whereas a Graphic card is a GPU embedded in its own motherboard, having its own cooling system and power supply and attached to the main motherboard via PCIe Slot. 

    AMD and NVIDIA are two main manufacturers of GPUs in the market. They both have a great number of choices.

    RAM (Memory): Select memory for the system depending on your requirements and motherboard support. Also look for form factor as per your board availability.

    Modern memory sticks come with preinstalled cooling systems.

    Storage: There are mainly two options while selecting storage for your system, HDD (Hard Disk Drive) and SSD(Solid State Drive). Both HDD and SSD are used to store data and install OS. SSD is a Solid State Drive and is considerably faster than HDD as  it doesn’t have any moving part like HDD, on the other side HDD has rotating disks packed together.

    HDD comes in two (2.5 inch and 3.5 inch) form factors, While SSD comes in many form factors.

    SSDs are more expensive than HDDs, so it will be a wise option to install Operating System and Applications on an expensive SSD and store Data which is less frequently accessed by computer systems on HDDs.

    PSU (Power Supply Unit): To meet power requirements of the computer a PSU is required. You must choose a PSU depending on your system and future upgrade requirements, also look for the power supply connector support you are using for your build.

    While selecting PSU you must look these features-

    • Wattage
    • 80 plus energy efficiency rating
    • Modularity

    Cooling System: Almost every Desktop cabinet comes with cooling fans for minimum to maximum cooling requirements depending upon price with some extra space for additional installations of cooling fans, Heat radiators. If you are planning to build a High performance PC you will require more cooling to run your system smoothly without errors.

    While selecting cooling fans keep in mind the motherboard support for the fan connectors, cabinet support for fan size, RGB/ARGB requirements , fan bearing type for smooth and longer life, noise level etc.

    PC Cabinet This is the Home for your MotherBoard and all its connected parts, Power Supply unit and Cooling fans, so you must choose your PC Cabinet wisely I am discussing this in the last because after selection of the above parts only you can decide which cabinet to use. It’s selection depends on the selection of CPU like if you select a multicore CPU then you will use liquid cooler which requires more space and hence a bigger cabinet same is  in the case of graphics card, Power supply unit and Motherboard.

    PC Cabinets are of the following types: Full Tower, Mid Tower, Mini Tower, Small Form Factor.

    Step 2

    Hardware installation.

    Step3

    BIOS Settings and OS installation. 

  • HTML Elements

    HTML Elements

    In HTML documents all elements are in the form of tags. HTML elements always starts and ends with the same tags the only difference is the forward slash </end tag>in the ending tag.

    Example 

    <h1>………….</h1>

    <p>………….</p>

    In between tags (elements) contents are inserted.

    Nested HTML Elements

    HTML elements can be in the nested form (One element can contain many elements ).

    Example

    <html>
<body>

<h1>Main Heading</h1>
<p>Paragraph.</p>

</body>
<html>

    Empty HTML Element 

    An empty HTML element does not contain anything. They do not have end tags, they are self closed

    Example 

    <br>, <hr>, <img>,<input>, <meta>, <link>

  • HTML Introduction

    HTML Introduction

    Introduction 

    HTML stands for Hypertext Markup Language. HTML is the basis of any webpage, it can be written in the most basic text editor like “notepad” in Windows to most advanc word editors.

    HTML documents are made of texts enclosed in between different types of “tags” these tags are called HTML elements.

    These elements are used for embedding and formatting different information like image, text, links, audio video etc to a web page further CSS (Cascading Style Sheet) is used for page layout and designing purpose.

    A Brief History Of HTML

    HTML 2.0 (1995)

    HTML 2.0 was the first complete version released in 1995 

    HTML 3.0 (January 1997)

    HTML 4.0 (December 1997)

    HTML 5.0 (October 2014)

    Example HTML document

    <!DOCTYPE html>
<html>
<body>

<h1>Main Heading</h1>
<p>Paragraph.</p>

</body>
<html>

    In the above example

    <!DOCTYPE html> is the html5 declaration.

    The whole html document is always enclosed in between html tags

    <html>

    ————————————————————-

    ————————————————————-

    </html>

    <body>—-</body> tag encloses the visible part of the document.

    Heading

    There are total six heading elements in HTML 

    <h1>First Heading</h1>

    <h2> Second Heading</h2>

    <h3>Third Heading</h3>

    <h4>Fourth Heading</h4>

    <h5>Fifth Heading</h5>

    <h6>Sixth Heading</h1>

    Heading size decreases from <h1> to <h6>.

    <p> ……. </p>  element is used for paragraphs. Each element declared in the begining must be closed following a forward slash  (/), except some exceptions which we will discuss later.

  • Share Photos without loosing Original Quality

    Transfer Files Using Google Drive

    Situation occurs when you have to share photos and videos to someone else, but if you use Whatsapp, Telegram or other such services you will loose the original Quality of your File, which is a problem.

    Best way to share photos in original quality

    There are various methods of sharing photos but the best of them is Google Drive

    First of all you create a Folder in your drive for example I have created and named it ‘Transfer’.

    Then click the + button at the bottom of the screen and upload the photos and videos you want to share in the Folder you have created.

    After you have uploaded all files just go to options and click on share option and enter the persons email address you want to share the files.

    Also you can select what recipients can or cannot do.

    Viewer: can Only view the Files

    Commenter: commenter can view and comment on photos and videos (Files)

    Editor: Editor can view, comment and edit Files

    An alternative way is to use the copy link option. Once you copy the link you can share the link and then give access once requested by the recipient.

    Advantage of this method of transferring files is that you can upload once and share many times as per your requirement.

    Once the job is completed you can delete the complete folder in this case ‘Transfer’ folder or individual files in the folder which you no longer want to share. Or you can delete the recipient.

    Disadvantage is that Google Drive Free subscription has limited storage of 15 GB. But you can upgrade your subscription plans to know more visit
