Unified Extensible Firmware Interface

The Unified Extensible Firmware Interface (UEFI), like BIOS (Basic Input Output System) is a firmware that runs when the computer is booted. It initializes the hardware and loads the operating system into the memory. However, being the more modern solution and overcoming various limitations of BIOS, UEFI is all set to replace the former.But what makes BIOS outdated?Present in all IBM PC-compatible personal computers, BIOS has been around since the late 1970s. Since then, it has incorporated some major improvements such as addition of a user interface, and advanced power management functions, which allow BIOS to easily configure the PCs and create better power management plans. Yet, it hasn’t advanced as much as the computer hardware and software technology since the 70s.Limitations of BIOSBIOS can boot from drives of less than 2 TB. 3+ TB drives are now standard, and a system with a BIOS can’t boot from them.BIOS runs in 16-bit processor mode, and has only 1 MB space to execute.It can’t initialize multiple hardware devices at once, thus leading to slow booting process.Difference between the Booting Process with UEFI and the Booting Process with BIOSBooting Process With BIOS : When BIOS begins it’s execution, it first goes for the Power-On Self Test (POST), which ensures that the hardware devices are functioning correctly. After that, it checks for the Master Boot Record in the first sector of the selected boot device. From the MBR, the location of the Boot-Loader is retrieved, which, after being loaded by BIOS into the computer’s RAM, loads the operating system into the main memory.Booting Process With UEFI : Unlike BIOS, UEFI doesn’t look for the MBR in the first sector of the Boot Device. It maintains a list of valid boot volumes called EFI Service Partitions. During the POST procedure the UEFI firmware scans all of the bootable storage devices that are connected to the system for a valid GUID Partition Table (GPT), which is an improvement over MBR. Unlike the MBR, GPT doesn’t contain a Boot-Loader. The firmware itself scans the GPT to find an EFI Service Partition to boot from, and directly loads the OS from the right partition. If it fails to find one, it goes back the BIOS-type Booting process called ‘Legacy Boot’.Advantages of UEFI over BIOSBreaking Out Of Size Limitations : The UEFI firmware can boot from drives of 2.2 TB or larger with the theoretical upper limit being 9.4 zettabytes, which is roughly 3 times the size of the total information present on the Internet. This is due to the fact that GPT uses 64-bit entries in it’s table, thereby dramatically expanding the possible boot-device size.Speed and performance : UEFI can run in 32-bit or 64-bit mode and has more addressable address space than BIOS, which means your boot process is faster.More User-Friendly Interface : Since UEFI can run in 32-bit and 64-bit mode, it provides better UI configuration that has better graphics and also supports mouse cursor.Security: UEFI also provides the feature of Secure Boot. It allows only authentic drivers and services to load at boot time, to make sure that no malware can be loaded at computer startup. It also requires drivers and the Kernel to have digital signature, which makes it an effective tool in countering piracy and boot-sector malware.UEFI doesn’t require a Boot-Loader, and can also operate alongside BIOS, supporting legacy boot, which in turn, makes it compatible with older operating systems. Intel plans to completely replace BIOS with UEFI, for all it’s chipsets, by 2020.

RAPED

“JUSTICE FOR ASIFA” I see these letters everywhere these days, A 8-year-old gets RAPED, where is our nation going?Are MEN in our country so jobless that their eyes are filled with lust rather than Dreams of a bright future? A girl merely 8 years old, gets raped, this was already a shock for her parents to add up to it, people made her a famous trend on porn websites…. WOW!!! Slow claps to all the those who helped in making a joke of her pride and dignity.And you know what is the best part of this? People in any case just find reasons to BLAME the FEMALE.Oh! She was a MUSLIM, that’s why she got RAPED!Oh! She wore jeans and top, that’s why she got RAPED!Oh My God! Ladki raat mei akele bahaar niklegi toh ye toh hona hi thaShe travelled by a private bus that’s why she had to face this…….…. GOD BLESS HER SOUL!Oh My God! She is a girl na, so ye toh hona hi tha… A 60-year old woman gets raped in our country, the men with those lustful eyes did not even spare 9-month-old baby, nor a woman wearing a burqa or lady wearing skirt, this was more than enough for me to belief that humanity became extinct. Leave HUMANS, these people did not even spare an animal HEADLINES: A MAN RAPES FEMALE DOG TILL DEATH. WOW!And what we do? Ask our girls to cover herself up in the so-called decent clothes, and not to go out of the house. Remember? a woman in BURQA was raped too and an uncle raped her 10-year-old nephew. Still you think your so-called guidelines for girls would help?! Don’t you think it’s high time to set some guidelines for your beloved boys?STOP looking for excuses to blame the victim… SHE WAS RAPED! A FEMALE WAS RAPED! It has completely nothing to do with her religion/ length of her clothes/ the time she was raped or just ANYTHING!!!!!! The thing that should matter is that a female got RAPED! And the culprit should be hanged till death… YES! DEATH PENALTY FOR RAPE Because RAPE ruins not only the life of a victim but also her soul. RAPE not only affects ONE life but many, be it the victim’s life or her parent’s life, a rape affects the lives of many million other females living in this chauvinistic society.BLAME THE CULPRIT AND NOT THE VICTIM!

Why live to Impress Others

Don't compare yourself with anyone in this world...if you do so, you are insulting yourself.” ― Bill GatesIn the present world ,where right from the titles of songs, carrying on to the contents of phrases and quotations we all say “Be yourself”,Why? Why there’s a need to remind ourselves to be us? Are we not happy with who we really are?In today’s world we are living, not because we love to live, but we need to exist, as, if we loved to live our lives, then, we would have been more satisfied and happy with who we are and didn’t find it a need to impress others by creating a negative image of us. Nowadays, whatever we do is aimed at achieving a certain image in a society or among a group of people. The question here arises, why we want to leave a fake impact of ourselves in others minds rather than a real one?“To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.”The youth is highly affected by this problem, as, whatever they say and whatever they do is highly influenced by the people they are surrounded by. Generally, they do what the others are interested in, like, wearing kinds of clothes which made them look “cool”, despite the fact that they are uncomfortable in it, they do this to attain a look which others are fond of . In this whole game, we somewhere or the other loose our true personality, our true interests for some human beings who didn’t even care of who we are!“The biggest ingredient in a best friend is someone whose actions you respect and who you can truly be yourself around. “After losing our true personalities we tend to ask for help mainly from Internet by typing, “How to be yourself?"Is this needed? Like sacrificing ourselves for someone who was a no one in our life.At last, we can say that, being ourselves is more impressive than impressing others. We just need to know what we really are and do what we love to do, rather than being someone what someone else wants , which we are truly blessed with.“I am a rare species, not a stereotype.” ― Ivan E. Coyote
