The document discusses computer buses and their role in transferring data between different computer components. It defines what a computer bus is, describes different types of buses including data buses, address buses, and control buses. It explains how buses transfer data at different speeds depending on their width and frequency. The document also covers internal and external buses, and how chipsets are used to route data between different buses.

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.
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.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
2. Introduction
In the computer bus is
a subsystem that
transfer data between
different component of
the computer. Early
computer use electrical
wire to connect
between components.
Today’s computer uses
parallel and bit serial
connection.
3. What is computer Bus
In the computer Bus is the set of
physical connection in between
cables and printed circuits. It is
sheared by different hardware
component in order to
communicate each other. It
reduces the pathway between
different component. Sometimes
it is called the data highway.
4. Characteristic of Bus
Bus can be characterized by
amount of information can
transfer in a certain period of
time. This expressed in a bit. A 32
wire ribbon cable can transmit 32
bit in parallel. Term used width to
define transfer rate. It also
defined by frequency, that is
number of packet sent or
received per second.
5. Transfer speed of Bus
It is very easy to find the
maximum speed of or transfer
rate of Bus. Transfer rate of a bus
can be find the amount of data
can transport in a unit of time
and multiplying it by the width of
it’s frequency. If a bus with 16 bit
and frequency 133 MHz then
transfer rate would be 16 *
133.106 bits/s
6. Types of Bus
Each bus generally constitute
of 50 to 100 distinct physical
lines divided into three types
these are address bus , data
bus and control bus. There
are other buses also these
are universal serial bus,
peripheral buses etc.
7. Address Bus
It is sometimes called memory
bus. It transfer the memory
address to the processor in
which CPU wants to access.
This is a unidirectional bus.
When the processor wants to
read or write a memory location
that location is specified in the
memory location.
8. Data Bus
This bus transfer instruction to
the processor. It is bidirectional
bus, means data or electronic
signal can transfer in both side.
It is a computer sub system, it
can transfer data between
different component. It is 32
wide means in every second up
to 32 bit data can transfer.
9. Control Bus
It is also called command
bus. It transport command
and synchronization signal
those coming from control
unit and going towards
hardware component. This is
a bidirectional bus. It transmit
response signal also.
10. Primary Buses
Computer system generally
consist of CPU, main memory
and verity of peripheral
component. All buses
connecting between these
components these all buses
are called system bus. These
are internal bus and external
bus.
11. Internal Bus
Internal bus connect all the
internal component of the
computer such as CPU, memory
and motherboard. It is also refer to
as local bus because they are very
much involved in the local device.
This is very fast and independent
from rest of the system. It’s main
purpose allows the processor to
communicate with RAM.
12. Chipset
It is a component it routes data between different
buses. It is composed of large number of
electronic chip It has two component north and
south bridge.
North bridge :- It transfer control between
processor and RAM.
South bridge :- It handles communication
between peripheral devices.
13. PCI Bus
It is used to address all problem
faced by video, disk (SCSI and IDE).
However it is a high performance
bus. General computer system
consist of processor chip with high
speed cache. It is 32 bit bus capable
of transforming 32 bit of data. A
bridge chipset allows system I/O
connection. Example of this bus
Qlogic 8GB HBA.
