What are the GPT and MBR?

GPT and MBR are both partition style on a physical hard drive. They both have their characteristics.

GPT, a standard layout for the partition table on the physical hard drive, is short for the GUID partition table. It uses the UEFI (Unified Extensible Firmware Interface) mode. In GPT, you can create partitions up to 128.

MBR (Master Boot Record) uses Legacy BIOS mode. In MBR, you are only allowed to create four primary partitions or three primary partitions and one extended partition at most. However, it has great compatibility.

Owing to they both has their own model, so you must boot your computer with their own mode. If your hard drive is GPT, you can only boot from UEFI. If your hard drive is MBR, you can merely boot from Legacy BIOS.

Convert GPT to MBR using command prompt

When we meet disk or partition problems, most of us will think about the Windows built-in tool. To some extent, it is very useful and can solve some problems for us like Convert GPT to MBR on Windows 7/8/10. To convert GPT to MBR without data loss using a command prompt, you are supposed to back up the disk first and then convert. Below is the guide to the conversion process:

Step 1: Click “Win + R”, type cmd in the Run window. If you want to convert GPT to MBR during installing Windows, you can press Shift + F10 to bring out the command prompt. After you open the cmd window, type diskpart.exe, and click Enter.
Step 2: Type list disk and click Enter
Step 3: Type select disk n (n is the number of the disk you want to clean)
Step 4: Type clean
step 5: Type select disk n (n is the number of the disk you want to convert)
Step 5: Type convert MBR
Step 6: Type exit

GPT እና MBR ምንድናቸው?

GPT እና MBR በአካላዊ ደረቅ(physical Hard Drive) አንጻፊ ላይ ሁለቱም የክፍልፋይ ቅጥ(partition style) ናቸው። ሁለቱም ባህሪያቸው አሏቸው ፡፡

በአካላዊ ደረቅ አንጻፊ ላይ ለክፍለ-ነገር ሰንጠረዥ መደበኛ አቀማመጥ GPT ለ GUID ክፍልፍል ሰንጠረዥ አጭር ነው ፡፡ የ UEFI (የተባበረ Extensible Firmware በይነገጽ) ሁነታን ይጠቀማል። በ GPT ውስጥ እስከ 128 ድረስ ክፍሎችን መፍጠር ይችላሉ ፡፡

MBR (ማስተር ቡት ሪኮርድ) የቆየ ባዮስ (BIOS) ሁኔታን ይጠቀማል ፡፡ በ MBR ውስጥ ቢበዛ አራት የመጀመሪያ ክፍልፋዮችን ወይም ሶስት የመጀመሪያ ክፍልፋዮችን እና አንድ የተራዘመ ክፋይ ብቻ እንዲፈጥሩ ይፈቀድልዎታል ፡፡ ሆኖም ፣ እሱ ትልቅ ተኳሃኝነት አለው።
በሁለቱም ምክንያት የራሳቸው ሞዴል አላቸው ፣ ስለሆነም ኮምፒተርዎን በራሳቸው ሁነታ መነሳት አለብዎት። ሃርድ ድራይቭዎ GPT ከሆነ ማስነሳት የሚችሉት ከ UEFI ብቻ ነው ፡፡ ሃርድ ድራይቭዎ MBR ከሆነ ፣ ከ Legacy BIOS ብቻ ማስነሳት ይችላሉ።

የትእዛዝ ጥያቄን በመጠቀም GPT ን ወደ MBR ይቀይሩ

የዲስክ ወይም የክፋይ ችግሮች ሲያጋጥሙን አብዛኞቻችን ስለ ዊንዶውስ አብሮገነብ መሣሪያ እናስብበታለን ፡፡ በተወሰነ ደረጃ ፣ እሱ በጣም ጠቃሚ ነው እናም በዊንዶውስ 7/8/10 ላይ GPT ን ወደ MBR ይለውጡ እንደ እኛ አንዳንድ ችግሮችን ሊፈታ ይችላል ፡፡ የትእዛዝ ጥያቄን በመጠቀም GPT ን ወደ MBR ያለ የውሂብ መጥፋት ለመቀየር በመጀመሪያ ዲስኩን ምትኬ ማስቀመጥ እና ከዚያ መለወጥ ይጠበቅብዎታል ፡፡
ወደ ልወጣ ሂደት መመሪያ ከዚህ በታች ነው-
ደረጃ 1: “Win ​​+ R” ን ጠቅ ያድርጉ ፣ በሩጫ መስኮት ውስጥ cmd ብለው ይተይቡ። ዊንዶውስን በሚጭኑበት ጊዜ GPT ን ወደ MBR መለወጥ ከፈለጉ የትእዛዝ ጥያቄውን ለማምጣት Shift + F10 ን መጫን ይችላሉ ፡፡ የ cmd መስኮቱን ከከፈቱ በኋላ diskpart.exe ብለው ይተይቡ እና Enter ን ጠቅ ያድርጉ።
ደረጃ 2: የዝርዝር ዲስክን ይተይቡ እና አስገባን(Enter) ጠቅ ያድርጉ

LG’s stylish mid-range Velvet smartphone

The LG Velvet has finally officially launched in South Korea, following weeks of teases and announcements. As expected, the phone features a “raindrop” triple rear camera array, is powered by a Snapdragon 765, and has a 6.8-inch OLED display with a small central notch. Details about its global launch are expected to come later this month.

We also knew the specs of its cameras, display, and battery thanks to a blog post published late last month. The main camera has a 48 megapixel sensor, and it’s joined by an 8 megapixel ultra-wide camera, a 5 megapixel depth sensor, and a 16 megapixel front-facing camera. Internally, the phone has a 4,300 mAh battery and supports both fast and wireless charging.

The Velvet is available in orange, green, black, and white.

Rounding out the specs, the phone has 8GB of RAM, 128GB of storage, an IP68 water resistance rating, and an in-display fingerprint sensor. It supports styluses and LG’s dual screen accessory, and it’s available in orange, green, black, and white. Oh, and there’s a 3.5mm headphone jack, because this is LG after all.

The LG Velvet is due to cost ₩899,800 (around $700) when it goes on sale in South Korea. Although the company is yet to announce pricing or release information for outside of the country, LG tells us that it’s planning to make an English-language announcement later this month, suggesting that a release in the US and Europe can’t be far away. That’s good news, because the Velvet is one of the most interesting looking phones LG has produced in a while.

Thing to Consider Before Buying Your Computer

now a day's our life is really attached to information Technology, and money people now a day's use computer for money reason, even in our country means in Ethiopia time to time the No of people using or having a computer are tremendously increasing so When entering into the world of computers it can get very easy to get confused and loose sight of your goals and sometimes your budget, the increment of types of computer manufacturer and so so on. for this reasons you should consider the following things before you Owen(buy your Own PC)..Here's the top 7 things to consider;

First and for most, know what you want to use it for and set aside a realistic budget.

Your budget
The first thing that most of us are constrained to is budget so this is the first thing you should consider. We always want the best but we need to be grounded on what we can afford. So Get a budget and stick to it.

Laptop or Desktop?
The next thing you should be looking at is your requirements. Do you need a laptop or desktop? What is the machine going to be used for? Once you have done this go back to number one and see if these are compatible often they are not first time round. You either need to adjust your budget or adjust your goals to make them more compatible with each other.

then:-Now its time to look at the computer.There are many things to consider when actually buying the computer, here I will list the most important so you can choose wisely.

1. The Processor
This is the most important factor when choosing a computer nowadays and there are many factors in processor choice the main thing is that in my opinion Intel are at the moment making the best chips and their core i5 to i7 is the best interns of the reason, so go for one in this family and you will be ok.

2. RAM (Computer Memory)
Essentially, the more rams you have, the more browsers and applications you can open. 4Gb is the most basic nowadays. 8GB is the sweet spot for most people. If you are a gamer, photo or video editor, or planning to do CAD/CAM work, you need at least 16GB of Ram. Make sure you get windows 10 64bit as your operating system.

3. Hard Drive
This is the next piece you should tackle. Computers today usually come with 500GB and 1TB of space in the hard drive. As more people are storing their information online on cloud storage, you may want to rethink of buying a huge hard drive space.

Where to get free cloud storage;
Google provides the 1st 15GB of free & monthly fee of $1.99 for 100GB and $9.99 for 1 terabyte.
Mega provides free 50GB
pCloud provides free 10GB
MediaFire provides 10GB
Dropbox provides 2GB
4. Graphics
Now all computers come with some form of graphics built in. But my recommendation is to go with something a little better possibly from NVIDIA or AMD. They make your computer resolution better. AMD cards are good for mining while NVidia is good for Adobe programs.

5. Computer Software
Most computers comes with microsoft software. The latest is Windows 10.

6. Anti-Virus Software
The last thing to do with the actual computer is a good virus and spy ware package. Don’t be under any illusion this is possibly the most important part of protecting your computer. It will get attacked at some point be prepared when it does.

7. Your Computer Lifeline, Internet
Finally the internet, get a good internet provider broadband at least. No computer is complete without a good internet.

I hope this list is helpful in helping you make vital decisions when buying your new computer.

What is the Difference between UEFI and BIOS

now a day's most new desktop and laptop computers use UEFI Firmware parallel with BIOS so for some reasons some peoples confuse about it. in order to that for today, a topic we would like to share what is UEFI and What is BIOS and There Difference just the highlight and for next time we prepare well formed and detail information about this two Firmware types.

The BIOS will soon be dead: Intel has announced plans to completely replace it with UEFI on all their chipsets by 2020. But what is UEFI, and how is it different from the BIOS we’re all familiar with?

UEFI (Unified Extensible Firmware Interface) and BIOS (Basic Input Output) are two different types of computer (PC) firmware which provide an interface between the operating system and the underlying hardware of your computer. BIOS is an earlier firmware developed by IBM in 1975. Although legacy mode (BIOS) is still widely used at this moment, a new modern firmware has evolved which is called UEFI and it is developed by UEFI consortium (which includes 140 technology companies).

UEFI uses GUID (GUID Partitioning Table) while BIOS uses MBR (Master Boot Record) partitioning styles. When you are installing an OS on your computer, ensure that you boot into the right mode. If you have a GUID partition, go for UEFI boot mode otherwise use BIOS.

How to Protect your Privacy in Windows 10

There has been some concern that Windows 10 gathers too much private information from users. Whether you think Microsoft's operating system crosses the privacy line or just want to make sure you protect as much of your personal life as possible, we're here to help. Here's how to protect your privacy in just a few minutes.

Turn off ad tracking

At the top of many people's privacy concerns is what data is being gathered about them as they browse the web. That information creates a profile of a person's interests that is used by a variety of companies to target ads. Windows 10 does this with the use of an advertising ID. The ID doesn't just gather information about you when you browse the web, but also when you use Windows 10 apps.

You can turn that advertising ID off if you want. Launch the Windows 10 Settings app (by clicking on the Start button at the lower left corner of your screen and then clicking the Settings icon, which looks like a gear) and go to Privacy > General. There you'll see a list of choices under the title "Change privacy options"; the first controls the advertising ID. Move the slider from On to Off. You'll still get ads delivered to you, but they'll be generic ones rather than targeted ones, and your interests won't be tracked.

You can turn off Windows 10's advertising ID if you want. You'll still get ads, but they'll be generic ones. (Click any image in this story to enlarge it.)
To make absolutely sure you're not tracked online when you use Windows 10, and to turn off any other ways Microsoft will use information about you to target ads, head to the Ad Settings section of Microsoft’s Privacy Dashboard. Sign into your Microsoft account at the top of the page. Then go to the “Interest-based ads: Microsoft account” section at the top of the page and move the slider from On to Off. After that, in the “Interest-based ads: This browser” section, move the slider from On to Off. Note that you need to go to every browser you use and make sure the slider for "Personalized ads in this browser" is set to "Off."

there is also something else to do to protect our privacy on windows 10, next time we will see the other two......
