x86-64 is a superset of the x86 instruction set architecture. x86-64 processors can run existing 32-bit or 16-bit x86 programs at full speed, but also support new programs written with a 64-bit address space and other additional capabilities.
Introduction into 64 bits for the beginners or where's again the 64-bit world?PVS-Studio
There were 64-bit processors, the operational systems, some programs. However completely all users have passed to 64 bits still far not. In article the reasons of it are considered.
I write this report to talk about 64x Architecture and explain what is the difference between 32x Architecture and 64x Architecture and what is the additional parts in 64x Architecture.

Questions concerned with the release of drivers for 64-bit versions of Windows are considered in this article. Some typical problems and the ways of their solutions are listed in the article as well as tools which simplify the process of drivers developing.
Lesson 19. Pattern 11. Serialization and data interchangePVS-Studio
Succession to existing data interchange protocols is an important component of the process of porting a program solution to a new platform. You need to provide the capability of reading the existing projects' formats, data interchange between 32-bit and 64-bit processes, etc.
The article reveals the meaning of the term "64 bits". It briefly discusses the history of 64-bit system development, describes the most popular 64-bit processors of the Intel 64 architecture and the 64-bit Windows operating system.
Lesson 27. Peculiarities of creating installers for a 64-bit environmentPVS-Studio
When developing the 64-bit version of an application, you should also be very attentive to the issue of program distribution - you might encounter some peculiar problems when installing the program on a 64-bit operating system, and if you forget about them, you will get a non-working installation package.
The reasons why 64-bit programs require more stack memoryPVS-Studio
In forums, people often say that 64-bit versions of programs consume a larger amount of memory and stack. Saying so, they usually argue that the sizes of data have become twice larger. But this statement is unfounded since the size of most types (char, short, int, float) in the C/C++ language remains the same on 64-bit systems. Of course, for instance, the size of a pointer has increased but far not all the data in a program consist of pointers. The reasons why the memory amount consumed by programs has increased are more complex. I decided to investigate this issue in detail.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

What is-32-bit-and-64-bit
1.
2. Introduction
As the number of bits increases there are two
important benefits.
More bits means that data can be processed in
larger chunks which also means more accurately.
More bits means our system can point to or address
a larger number of locations in physical memory.
32-bit systems could address (point to) 4 Gigabytes
of memory in one go. 64-bit systems are now
becoming more attractive because they can
potentially address up to 4 billion times that many
locations.
3. 32 Bits
Computers, operating systems, or software
programs capable of transferring data 32-bits at a
time. With computer processors, (e.g. 80386, 80486,
and Pentium) they were 32-bit processors, which
means the processor were capable of working with
32 bit binary numbers (decimal number up to
4,294,967,295). Anything larger and the computer
would need to break up the number into smaller
pieces.
Example of 32 bit Operating systems:
Windos 95 and Windows 2000
4. 64 Bit
Replacement for the older x86 or 32-bit platform, 64-
bit is a computer or software program that is capable
of transferring 64-bits at a time. With respect to
hardware, 64-bit is referencing the width of the
registers on a computer's microprocessor or the
computer bus; sometimes called WOW64 and x64.
Examples of 64-bit processors
AMD Opteron, Athlon 64, Turion 64, Sempron,
Phenom, FX, and Fusion.
Intel Celeron and Pentium 4 processors since
Prescott.
Intel Pentium Dual-Core, Core i3, Core i5, and Core
i7 processors.
5. Computer can be divided into
three layers
Their are three layers with the processor
or CPU as the central or lowest layer
and the application as the outermost or
highest layer as shown below:
6. To run a 64-bit operating system you
need support from the lower level: the
64-bit CPU.
To run a 64-bit application you need
support from all lower levels: the 64-bit
OS and the 64-bit CPU.
7. What 32-bit and 64-bit combinations are
compatible and will work together?
8. The main reason that 32-bit will always
run on 64-bit is that the 64-bit
components have been designed to
work that way. So the newer 64-bit
systems are backward-compatible with
the 32-bit systems (which is the main
reason most of us haven't moved to 64-
bit software).
10. Some questions about 32-bit
and 64-bit systems
Will a 64-bit CPU run a 32-bit program on a 64-bit
version of an OS?
Yes it will. 64-bit systems are backward-compatible with
their 32-bit counterparts.
Will a 64-bit OS run a 32-bit application on a 64-bit
processor?
Yes it will. Again, this is because of backward
compatibility.
Can 64-bit applications contain 32-bit code?
Yes, many times 64-bit software will contain portions of
32-bit code.
Similarly 32-bit software (usually very old programs) can
have some code in 16-bit which is why those 32-bit
applications will usually fail to run properly on a 64-bit OS.
11. Can 16-bit applications or code run on 64-bit
systems?
No, as we said previously. 16-bit code will NOT run
on 64-bit OS because the designers did not provide
backward-compatibility. This is one reason why some
32-bit programs will not work on 64-bit operating
systems.
Can a 64-bit CPU with a 32-bit host OS run a
virtual machine (VM) for a 64-bit guest OS?
Yes. It all depends upon the level of virtualization.
With software virtualization it is hardly likely to work,
or if it does work it may be very slow.
Hardware virtualization will need to be supported by
the CPU (e.g. with Intel-VT or AMD-V) and the BIOS.
12. Some questions about 32-
and 64-bit Windows
Can I run Windows 2000 and Windows XP
on a 64-bit CPU, and use old software?
Yes, a 32-bit OS (Windows 2000 or XP) will
run on a 64-bit processor. You should also be
able to run older 32-bit software on a 64-bit
OS.
How do find out if my system is 64-bit?
It is very simple, You have first right click on
My Computer and the select properties, a
window will open having information about the
your system. Here you can see your processor
is 32 bit or 64 bit.
13. Will my old device drivers work in Windows
64-bit
Many device drivers that work in Windows 32-
bit will not work in Windows 64-bit.
How do I run 32-bit software once I have
installed 64-bit Windows?
Windows 64-bit provides a 32-bit compatibility
mode called WOW32 (Windows 32-bit on
Windows 64-bit) that should run most if not all
your applications. But 32-bit Windows
applications are not automatically Windows
64-bit compatible. There are several reasons
for this: they have 16-bit code.
14. How can I tell if my application is 32-
bit or 64-bit?
Windows installs your programs to these
folders on your system drive:
• 'Program Files' for 64-bit programs
• 'Program Files (x86)' for 32-bit programs
In Task Manager, 32-bit processes will
usually have a suffix of '*32' and 64-bit
processes will not.
15. AMD64 Features
The AMD64 architecture includes these features:
• Register Extensions (see Figure 1-1 on page 2):
- 8 additional general-purpose registers (GPRs).
- All 16 GPRs are 64 bits wide.
- 8 additional YMM/XMM registers.
- Uniform byte-register addressing for all GPRs.
- An instruction prefix (REX) accesses the extended
registers.
• Long Mode (see Table 1-1 on page 2):
- Up to 64 bits ofvirtual address.
- 64-bit instruction pointer (RIP).
- Instruction-pointer-relative data-addressing mode.
- Flat address space.
