Computer viruses are small programs that spread from one computer to another and interfere with computer operations. They can corrupt or delete data, use email to spread, or delete everything on the hard disk. There are different types of viruses including boot viruses, program viruses, multipartite viruses, macro viruses, and activex viruses. Viruses usually spread via email, removable disks, or networks. To remove viruses, users should install and update antivirus software and scan the computer. They should also install operating system updates and use a firewall to protect the computer from future infections.

Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk.

A computer virus is a malware program that when executed replicates by inserting copies of itself into other computer programs, data files. When this replication succeeds, the affected areas are then said to be infected. Viruses often perform some type of harmful activity on the infected hosts such as accessing private information, corrupting data or even rendering the computer useless. However, not all viruses carry a destructive payload or attempt to hide themselves.

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.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
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.

2. What Is Computer Virus..??
A computer virus is a small software
program that spreads from one
computer to another computer and
that interferes with computer
operation.
A computer virus may corrupt or
delete data on a computer, use an
e-mail program to spread the virus
to other computers, or even delete
everything on the hard disk.
3. These viruses infect disc boot
records or master boot records in
hard disks. They replace the boot
record program, copying it
elsewhere on the disk or
overwriting it. Boot viruses load
into memory if the computer tries
to read the disk while it is
booting.
Examples: Form, Disk Killer,
Michelangelo, and Stone
virus
These infect executable
program files, such as those
with extensions like
.BIN, .COM, .EXE, .OVL, .DRV
(driver) and .SYS (device
driver). These programs are
loaded in memory during
execution, taking the virus with
them. The virus becomes active
in memory, making copies of
itself and infecting files on disk.
Examples: Sunday, Cascade
Types Of Viruses
•Boot viruses
•Program
viruses
4. • Multipartite
viruses
They infect
program files and
when the infected
program is
executed, these
viruses infect the
boot record. When
you boot the
computer next time
the virus from the
boot record loads
in memory and
then starts
infecting other
program files on
disk.
Examples:
Invader, Flip,
Tequila
• Macro viruses • Active x
virusesIt is a new type of computer
virus that infects the macros
within a document or
template. When you open a
word processing or
spreadsheet document, the
macro virus is activated and
it infects the Normal
template (Normal.dot)-a
general purpose file that
stores default document
formatting settings.
Examples:
DMV, Nuclear,
Word Concept.
ActiveX and Java
controls will soon be the
scourge of computing.
Most people do not
know how to control
there web browser to
enable or disable the
various functions like
playing sound or video
and so, by default, leave
a nice big hole in
the security by
allowing
applets free
run into
there
machine.
