Motherboard importance to computer and its failures to computer

• Obviously yes! The Motherboard or Main board is the vital part to computer because it is the backbone to a computer and it can controls the entire function inside the computer. 
• The main board is interacting with all the peripheral which are connected to computer and computer components.

  

  Importance of the Motherboard

•  It will allow the all parts of the computer to interact with each other.
• If the motherboard can arises the problem it can surely problem with other components also.
• All the computer components are reasonable price except motherboard it cost high.

 Motherboard failure and indication 

• If the troubleshoot occurs to the computer we usually see the blue screen on the monitor/display and it we unable solve the blue screen it indicates the problem to motherboard and it may leads to failure also.

Troubleshoots in Motherboard

• The age of the motherboard also lead to failure.
• Dust and smoke also leads to failure because when the smoke is combining with dust and it forms into sticky substance like the grease and it can overheat and lead to damage the motherboard.
• If the central processor unit fan fails the heating increases inside the C.P.U and it leads to damage the mother board.
• Random restart/shutdown is the common sign to failure of motherboard.
• Random On/Off will lead to damage the motherboard.
• If the burning smell comes from the Central Processing Unit instantly shutdown the computer and it is sign to motherboard failure. 

How many types/number of Beep sounds are there in computer?

Beep Sounds in Computer

Most of the computers users are hear the beep sound on their computer while boot of the computers or while working on the system it is due to problems in their Central Processor Unit. For every beep sound there is a code for it all the beep sounds are formed due to problems in mother board.

BIOS Short and long Beeps in computer

Generally short beep sounds are come by the BIOS (Basic Input Output System) when it is start-up a memory, cache, and processor error is encountered. The BIOS have numerous codes on beep sound when it is delivered of the short beep and long beep sounds.

There are eleven beep, with one long beep and short beep.

1 Beep: Refresh failure/Replace the memory and trouble shoot in mother board.
2 Beeps: Parity error Reset memory and trouble shoot in mother board.
3 Beeps: Error in first 64KB.
4 Beeps: Timer failure and troubleshoot in mother board.
5 Beeps: processor failure/ Central processor Unit fail to work.
6 Beeps: Trouble shoot in keyboard and fail to works controllers.
7 Beeps:  Exception error in Central processor Unit.
8 Beeps: Trouble in the video/display adapter.
9 Beeps: Read Only memory and BIOS (Basic Input Output System) have to replace.
10 Beeps: CMOS is failing to work on shutdown.  
11 Beeps: Troubleshoot in L2 cache.
Continuous Beeps: Error in memory, display and fail to boot.

 Short beep with long beep 

2 Short Beeps: Error in the post.

1 Long and 2 Short Beeps: Troubleshoot in memory at ROM, failure in BIOS at video.

1 Long and 3 Short Beeps: Troubleshoot in Memory at RAM and video DAC failure.   

Why operating System is crucial in Computer?

The Os is the Operating System which is referred as interface between the user and computer. The operating system can control everything in system like connecting the peripheral devices like mouse, printers, and keyboard. It is not only manages for peripheral devices it can manages the C.P.U (central processing Unit), and Applications which are essential for the users. The operating system is the main source for the displaying of the icons, computer applications, videos and more it is the vital source for monitor to vision entire things on it.

Functions of Operating System

 The first operating system was developed in 1956 by Robert L. Patrick for the use of the IBM 704 main frame. It is first operating system and it was used for fourty IBM 704 mainframes.

Types of Operating Systems

Most of the people work with the different operating system in their computer. In the world there are different types of Operating Systems like Linux, Unix, Microsoft Windows, and Apple Mac OS X. In that most of the personal computer users are used Microsoft Windows, Apple Mac OS X and Linux. These are the most commonly used by the computer users for operating system. 

Types of operating system

What is GUI in Operating System?

In operating system we commonly hear that GUI which means Graphic User Interface. It is used for the operating of mouse to click on icon button and Menu button on monitor. For every operating system there is different type of GUI which is suits for its operating system.

The operating systems are designed for the friendly user only and operating systems are main source to computers to work.

Why Li-Fi is 100 times faster than Wi-Fi?

Li-Fi is a Light Fidelity it is the most prominent feature in the internet world and it can browse the file or data within fraction of seconds and it maintains the speed of 224 gigabytes per second it more than Wi-Fi speed in Li-Fi there are 3 main sections are there.

1. What is Li-Fi?
2. How it works?
3. What is difference between Li-Fi and Wi-Fi?

What is Li-Fi?

The Li-Fi is a Light Fidelity it works with the Led Light bulb which is regularly used in households it is main source to Li-Fi. It was invented by the Harald Haas and he teaches in Edinburgh university in Scotland on United kingdom on that time he get an idea why the internet works with the radio waves why cannot works with another waves he did lot of research in Li-Fi and he get succeed and he tells Li-Fi is Visible Light Communication system which means that it has Photo detector it can receive the light signals and the light signals can convert into data signals it mains source for the Li-Fi. 

Li-Fi future Internet

It can provides the speed 224 gigabytes per second and it can download or upload within seconds it has faster internet and earns 1Gb per second it means it is 100 times better than Wi-Fi and the Wi-Fi speed is in Mbps only and Li-Fi speed is in Gigabyte. 

How it works?

The Li-Fi works with Led Light bulb which is most commonly used in houses it emits the light rays this rays are the visible light it is the source signal to Li-Fi. It has the VLC system it means that Visible Light Communication system it is the Photo detector it captures and converts into data signals. Li-Fi gives the speed about 224 gigabytes and it can download or browse the files or movies or software applications within fraction of seconds it can gives 1Gb for 1 second it is higher to Wi-Fi speed and it is 100 times better than Wi-Fi.

Li-Fi at everywhere

The Internet devices can work under the Led light only and it can maintains the good speed  and it can transfers the data within second and it cannot seen by humans with their eyes because it faster. It cannot pass the light rays through the walls it is the one of safety measure to protect other to use this feature. 

 The Led is a semiconductor it can have stable in speed and it can controls speed it can maintains the speed with the on and off and we cannot see the speed.

The Li-Fi works with small microchip when we attach to the led it can gives internet to devices with high speed.

Difference between Wi-Fi and Li-Fi

The Wi-Fi and Li-Fi is quite different in their speed both of them are crucial role in the technology but Li-Fi have more speed and it gives 224 gigabytes per second and Wi-Fi cannot give that much speed. 

Difference between Wi-Fi and Li-Fi

Wi-Fi

• Wi-Fi stands for Wireless Fidelity.
• It speed can be seen in Mbps per second.
• It can works with the radio waves and this waves can be convert into source Data signals.
• Wi-Fi frequency can be seen in GHz transfers 54 megabits per second.
• The accessibility can be done with the hot spot only.
• It can be track signals through the router only.
• It can pass through the wall and it maintains the some distance according to its model.

Li-Fi 

• Li-Fi sands for Light Fidelity.
• It speed can be seen in gigabytes per second.
• It can works with the visible light with Led bulb.
• The Li-Fi frequency can be seen in gigabits per second.
• It requires the accessibility with Led bulb.
• The Li-Fi works with Led only and it should be on throughout the day.
• It Li-Fi signals cannot pass through the wall because the light cannot pass through the wall.
• Li-Fi works with the small microchip when it is attached to the led.

Why the Sunstroke attacks and its Precautions

Why the Sunstroke or Heatstroke attacks?

Well in the summer season we hear that most commonly sunstroke attacks firstly we have to know that what is sunstroke how the sunstroke attacks and what are it symptoms. The sunstroke is also called has heatstroke it attacks due to high temperature generated on the body it is due to heat exposure on the outside of the body which emits by the sun at that time the body temperature increases and leads to sunstroke or heat stroke.

How the Sunstroke attacks

Normally the body average temperature of the humans is 37 degrees Celsius and in Fahrenheit 98.6 degrees Fahrenheit if the body temperature goes high from normal temperature to high temperature it lead to sunstroke in the body heat cannot control by itself we have to provide the internal cooling substances to the body and it then cools and decreases the temperature and protect from the heatstroke.

Heat stroke result in high temperature in the body due to less water it can called as dehydration which can due to drinking of less water it results to shortage of water in body and fails to controls the body temperature.   

Symptoms for the sunstroke

• High headache.
• Sweating high.
• Skin color changes into red hot.
• Vomiting.
• Muscles cramp.
• Urine color changes into dark. 

Tips to avoid the Sunstroke

On the heatstroke or Sunstroke lot of people gets unconscious and get illness on that time we have to follow the some useful medical tips which are readily available to us like protect them for sun shine and take them to hospitals.

Avoid day time journey in Summer season

• Take the lite food on summer season.
• Avoid the non vegetarian food mostly.
• Drink the water more and it leads to decrease the body temperature and help to remove impurities.
• Take the lemon juice it will more benefit to you and it cools the body instantly if anybody gets illness or unconscious they can easily recover with this.
• Drink the coconut water it has lot of minerals and vitamin it can reduce the temperature give instant result.
• Take the fruits more it can decrease the body temperature.
• Drink the Butter milk it will control the temperature and gives more healthy benefits.

Drink more Water and Coconut water to protect from sunstroke

• Protect your skin from direct sun light by covering the face hands with clothes and applying sun cream and lotions.
• Mostly avoid the day time journey from 11 am to 4 pm.
