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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

information
(output)
Information Processing Cycle
6. Data And Information
Data is any collection of numbers, characters or
other symbols that has been coded into
a format that can be input into a computer and
processed. Data on its own has no meaning, or
context. It is only after processing by a computer that
data takes on a context and becomes information.
9. The Components of a Computer
A computer contains many electric, electronic, and mechanical components known
as hardware
-
• Allows you to enter data and instructions into a computerInput Device
• Hardware component that conveys information to one or more peopleOutput Device
• Case that contains the electronic components of the computer that
are used to process dataSystem Unit
• Records (writes) and/or retrieves (reads) items to and from storage
mediaStorage Device
• Enables a computer to send and receive data, instructions, and
information to and from one or more computers or mobile devices
Communications
Device
11. Keyboard
A computer keyboard contains keys you press to enter data
into the computer . For security purposes ,some keyboards
include a fingertip reader, which allows you to work with the
computer only if your fingertip is recognized.
12. Mouse
A mouse is a small handheld device. With the mouse, you
control movement of a small symbol on the screen, called the
pointer, and you make selections from the screen.
13. Microphone
A microphone is an example of a transducer, a device that changes
information from one form to another. Sound information exists as
patterns of air pressure; the microphone changes this information into
patterns of electric current. The recording engineer is interested in the
accuracy of this transformation, a concept he thinks of as fidelity.
14. Scanner
A scanner is a device that captures images from photographic prints,
posters, magazine pages, and similar sources for computer editing and
display. ... Very high resolution scanners are used for scanning for high-
resolution printing, but lower resolution scanners are adequate for
capturing images for computer display.
15. Web Cam
The term webcam is a combination of "Web" and "video camera." The
purpose of a webcam is, not surprisingly, to broadcast video on the
Web. Webcams are typically small cameras that either attach to a user's
monitor or sit on a desk. Most webcams connect to the computer via USB,
though some use a Fire-wire connection
16. Output Devices
An output device is any device used to send data from a
computer to another device or user. Most computer
data output that is meant for humans is in the form of audio
or video. Thus, most output devices used by humans are in
these categories.
Examples
Printer
Monitor
Speaker
18. Printer
A printer is a device that accepts text and graphic output
from a computer and transfers the information to paper,
usually to standard size sheets of paper. Printers vary in size,
speed, sophistication, and cost. ... The inkjet sprays ink from
an ink cartridge at very close range to the paper as it rolls by.
19. Monitor
A monitor is an electronic visual computer display that includes a screen,
circuitry and the case in which that circuitry is enclosed. Older
computer monitors made use of cathode ray tubes (CRT), which made
them large, heavy and inefficient. ... A monitor is also known as a screen
or a visual display unit (VDU).
20. Speaker
Speaker is an output device that allow you to hear
music, voice and other audio.

Violation of Privacy
Public Safety
Impact on Labor Force
Impact on Environment
23. ADVANTAGES OF USING COMPUTERS
Speed:
When data, instructions, and information flow along
electronic circuits in a computer, they travel at incredibly
speeds. Many computers process billions or trillions of
operations in a single second.
Reliability:
The electronic components in modern computers are
dependable and reliable because they rarely break or
fail.
24. Continue….
Consistency:
Given the same input and processes, a computer
will produce the same results — consistently.
Computers generate error-free results, provided
the input is correct and the instructions work.
Storage:
Computers store enormous amounts of data and make
this data available for processing anytime it is needed.
25. DISADVANTAGES OF USING COMPUTERS
Some disadvantages of computers relate to the violation of
privacy, public safety, the impact on the labor force, health
risks, and the impact on the environment.
Violation of Privacy:
In many instances, where personal and
confidential records were not properly protected, individuals
have found their privacy violated and identities stolen.
26. Continue…
Public Safety:
Adults, teens, and children around the world are using
computers to share publicly their photos, videos, journals, music, and other personal
information. Some of these unsuspecting, innocent computer users have fallen victim
to crimes committed by dangerous strangers.
Impact on Labor Force:
Although computers have improved productivity and
created an entire industry with hundreds of thousands of new jobs, the skills of
millions of employees have been replaced by computers. Thus, it is crucial that workers
keep their education up-to-date. A separate impact on the labor force is that some
companies are outsourcing jobs to foreign countries instead of keeping their
homeland labor force employed.
27. Continue…
Health Risks:
Prolonged or improper computer use can lead to health
injuries or disorders. Computer users can protect themselves from health risks
through proper workplace design, good posture while at the computer, and
appropriately spaced work breaks. Another health risk, called computer addiction,
occurs when someone becomes obsessed with using the computer.
Impact on Environment:
Computer manufacturing processes and computer
waste are depleting natural resources and polluting the environment. Strategies
that can help protect the environment include recycling, regulating
manufacturing processes, extending the life of computers, and immediately
donating replaced computers.
28. Networks and the Internet
A network is a collection of
computers and devices
connected together, often
wirelessly, via
communications devices and
transmission media
29. Networks and the Internet
The Internet is a worldwide collection of networks that connects millions
of businesses, government agencies, educational institutions, and
individuals
30. Networks and the Internet
People use the Internet for a variety of reasons:
Communicate Research and Shop Bank and Invest Online Trading
Entertainment Download Videos Share Information Web Application
31. Networks and the Internet
A social networking Web site encourages members to share their interests,
ideas, stories, photos, music, and videos with other registered users
32. Computer Software

thin and lightweight, yet can be as powerful as the average desktop
computer. Notebook computers usually are more expensive than desktop
computers with equal capabilities.
41. Game Consoles
A game console is a
mobile computing device
designed for single-
player or multiplayer
video games
42. Servers
A server controls access to the
hardware, software, and other
resources on a network and
provides a centralized storage
area for programs, data, and
information. Servers support
from two to several thousand
connected computers at the
same time.
43. Mainframes
A mainframe is a large, expensive, powerful computer that can
handle hundreds or thousands of connected users
simultaneously. Mainframes store huge amounts of data,
instructions, and information. Most major corporations use
mainframes for business activities. With mainframes, large
businesses are able to bill millions of customers, prepare
payroll for thousands of employees, and manage thousands
of items in inventory. One study reported that mainframes
process more than 83 percent of transactions around the
world.
45. Supercomputers
A supercomputer is the fastest, most powerful computer — and
the most expensive. The fastest supercomputers are capable of
processing more than 135 trillion instructions in a single second.
Applications requiring complex, sophisticated mathematical
calculations use supercomputers. Large scale simulations and
applications in medicine, aerospace, automotive design, online
banking, weather forecasting, nuclear energy research, and
petroleum exploration use a supercomputer.
47. Super-Computer in Pakistan
The high performance supercomputing program started in mid-to-
late 1980s in Pakistan. Supercomputing is a recent area of Computer
sciencein which Pakistan has made progress, driven in part by the growth
of the information technology age in the country. Developing on the
ingenious supercomputer program started in 1980s when the deployment
of the Cray supercomputers was initially denied.
The fastest supercomputer currently in use in Pakistan is
developed and hosted by the National University of Sciences and
Technology at its modeling and simulation research centre. As of November
2012, there are no supercomputers from Pakistan on the Top500 list.

and Office Machines
50. Because embedded computers are components in larger products, they
usually are small and have limited hardware. Embedded computers
perform various functions, depending on the requirements of the product
in which they reside. Embedded computers in printers, for example,
monitor the amount of paper in the tray, check the ink or toner level,
signal if a paper jam has occurred, and so on. shows some of the many
embedded computers in cars.

Another category of user, called a power user, requires the capabilities of a
powerful desktop computer, called a workstation. Examples of power users include
engineers, scientists, architects, desktop publishers, and graphic artists. Power users
typically work with multimedia, combining text, graphics, audio, and video into one
application. These users need computers with extremely fast processors because of
the nature of their work.
56. Large Business User
A large business has hundreds or thousands of employees or customers that work
in or do business with offices across a region, the country, or the world. Each
employee or customer who uses a computer in the large business is a large
business user. Many large companies use the words, enterprise computing, to refer
to the huge network of computers that meets their diverse computing needs. The
network facilitates communications among employees at all locations. Users access
the network through desktop computers, mobile computers, PDAs, and smart
phones.
57. COMPUTER APPLICATIONS IN SOCIETY
The computer has changed society today as much as the
industrial revolution changed society in the eighteenth and
nineteenth centuries. People interact directly with computers
in fields such as education, finance, government, health care,
science, publishing, travel, and manufacturing. In addition,
they can reap the benefits from breakthroughs and advances
in these fields. The following pages describe how computers
have made a difference in people’s interactions with these
disciplines.
60. Education
Education is the process of acquiring knowledge. In the
traditional model, people learn from other people such as
parents, teachers, and employers. Many forms of printed
material such as books and manuals are used as learning
tools. Today, educators also are turning to computers to assist
with education. Many schools and companies equip labs and
classrooms with computers. Some schools require students to
have a notebook computer or PDA to access the school’s
network or Internet wirelessly.
62. Finance
Many people and companies use computers to help manage
their finances. Some use finance software to balance
checkbooks, pay bills, track personal income and expenses,
manage investments, and evaluate financial plans. This
software usually includes a variety of online services. For
example, computer users can track investments and do online
banking. With online banking, users access account balances,
pay bills, and copy monthly transactions from the bank’s
computer right into their computers
64. Government
Government A government provides society with direction by
making and administering policies. To provide citizens with up-
to-date information, most government offices have Web sites.
People access government Web sites to file taxes, apply for
permits and licenses, pay parking tickets, buy stamps, report
crimes, apply for financial aid, and renew vehicle registrations
and driver’s licenses.
