INTRO-
In the ubiquitous network society, where individuals can easily
access their information any time and anywhere, people are also faced with the risk that
others can easily access the same information anytime and anywhere. Because of this
risk, personal identification technology is used which includes Passwords, personal
identification numbers and identification cards.
However, cards can be stolen and passwords and numbers can be guessed or forgotten. To
solve these problems, Fujitsu developed four methods:fingerprints, faces, voice prints and
palm veins. Among these, because of its high accuracy, contact less palm vein
authentication technology is being incorporated into various financial solution products
for use in public places. This paper palm vein authentication technologies and some
examples of its application to financial solutions.

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.
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.

String It is hot outside
Integer 457
Floating Point 3.548
What data type is counter?
Please define the following
Variable
Iteration
Algorithm
Syntax error
3. Network Topology
Network topology refers to how computers are connected to a
network. There are three main types of network topology: bus, ring
and star.
The bus network
In a bus network all the workstations, servers and printers are joined
to one cable (the bus). At each end of the cable a terminator is
fitted to stop signals reflecting back down the bus.
The ring network
In a ring network each device (workstation, server, printer) is
connected to two other devices, this forms a ring for the signals to
travel around. Each packet of data on the network travels in one
direction and each device receives each packet in turn until the
destination device receives it.
The star network
In a star network each device on the network has its own cable that
connects to a switch or hub. A hub sends every packet of data to
every device, whereas a switch only sends a packet of data to the
destination device.
Pick one of the topologies and research their advantage and
disadvantages as well providing a drawing of a typical layout.
4. DECIMAL BINARY CORRECT?
0 8 4 2 1
1 8 4 2 1
2 8 4 2 1
3 8 4 2 1
4 8 4 2 1
5 8 4 2 1
0 1 0 1
Example
6 8 4 2 1
7 8 4 2 1
8 8 4 2 1
9 8 4 2 1
10 8 4 2 1
Binary Numbers
Binary means two. All
numbers in binary are
made up of either a 0 or a
1.
To work out a decimal
number we use a grid like
the ones on a left.
Decimal number 5
Is there any eights in five?
NO! so a zero goes in the
eight column.
Are there any fours in 5.
Yes so we put a 1 in the
four column.
Leaving one!
So we out the one in the 1
column and not the two
column
Now work out the binary
numbers for the other
questions.
6. Database / SQL
Table = Menu
Meal-code Name Price Meal-deal
1001 Fish Fingers 1.99 No
1002 Hot Dogs 2.85 No
1003 Turkey Burgers 2.19 No
1004 Jacket Potato 2.50 Yes
1005 Chicken Korma 3.25 No
Which of the above would be the primary key?
The following SQL statement has been executed to the database table
above what would happen?
SELECT Name, Price, Meal-deal
FROM Menu;
Where Meal-code = 1004;
7. Data Structures (revision only)
The study of data structures is about organising data so that it is suitable
for computer processing. Computer hardware looks at storage devices
like internal memory and disks as holders of elementary data units
(bytes), each accessible through its address (usually an integer).
Defining data structures
A data structure can be defined as a collection of different data
elements, which are stored together in a clear, structured form.
In programming, one of the most important design decisions involves
choosing which data structure to use. Arrays and linked lists are among
the most common data structures and each is applicable in different
situations.
Data structures: arrays
There are situations during the writing of code when programmers need
to hold related data as a single item, for example a list of employees’
names or makes of car. One method of doing this would be to assign a
variable to each item in the list.
One-dimensional arrays
A one-dimensional array in Python and PHP is a data structure that
allows a list of items to be stored with the capability of accessing each
item by pointing to its location within the array.
0 1 2 3
0 A B C D
1 E F G H
2 I J K L
3 M N O P
8. The reason why this type of array is referred to as a
‘one-dimensional array’ is that it only uses a single
number to point to the position of array elements.
Two-dimensional arrays
Two-dimensional arrays are a little more complex than the one-
dimensional versions, but really they are nothing more than an array of
arrays, in other words an array in one row and another in the next row.
4 Q R S T
9. Hardware
Hardware is a name given to a collection of physical ‘things’ that when
put together in a certain way form a ‘system’.
Computer hardware: system unit
Within a computer system there are basically two types of hardware. The
hardware within the system consisting of the CPU (central processing
unit), which is situated on a printed circuit board called the motherboard.
There is the hard disk drive, the RAM (random access memory), optical
drive and other circuit boards such as the graphics and sound cards.
These are all regarded as hardware because if you removed the case you
could physically touch the devices – although you should not do this
unless you know what you are doing.
Describe what the purpose of CPU & RAM along with
typical specs and costs each.
