I. Write
short notes on:
1. Blaise Pascal, a French Mathematician,
in the year 1642 developed an adding machine, known as Pascal’s Adding Machine
(Pascaline). It was the first ever mechanical and automatic calculating machine
or calculator. This machine could perform only addition and subtraction.
Moreover, multiplication can also be done with the repeated addition.
2. John Napier, a Scottish
Mathematician, in the year 1617 developed a manually operated calculating
device named as Napier’s Bones. It was considered to be the world’s first
calculator that could multiply, divide and find the square root of a number.
II.
Answer the following questions.
1. 1. Abacus, a calculating machine, comprises a rectangular wooden frame on which vertical rods are fixed. This rectangular wooden frame is divided into two unequal parts. The upper part is known as Heaven, has two beads in each rod, and the lower part has five beads in each rod, and is known as Earth. Each bead of Heaven is equal to five units and each bead of Earth is equal to one unit. We bring the beads near the divider to represent a number. The extreme right rod denotes the unit’s place and the rods towards left represent ten’s place, hundred’s place and so on. If no bead is present near the divider, then the value is considered to be zero. When a bead of Heaven is brought near the divider, the value becomes five and when a bead of the Earth is brought near the divider, the value becomes one.
The number represented on the abacus is 2,364.
2. Charles Babbage, also known as “Father of Computer” had contributed in many different scientific fields but his most important contribution was designing a programmable computing device which is served as the blue print for other more complex machines. He had given the concept of the first form of computer on which today’s computers are designed.
3. 3. A computer has a number of characteristics.
Some of them are:
i.
Speed – A
computer can perform calculations at a very fast speed. It can perform
thousands of mathematical operations in a fraction of a second.
ii.
Accuracy – A computer
is a highly accurate electronic device. It performs each and every calculation
with the same accuracy.
iii.
Storage - A
computer has a memory that stores all the data and information. The data
remains in the memory of the system unless it is deleted.
iv.
Diligence – A
computer, unlike humans, does not get tired. It can work continuously for hours
without any error. It will maintain the same accuracy and speed even after
millions of calculations.
v.
Versatility - A
computer is a multi-purpose machine which can perform a variety of tasks.
4. Limitations of a computer are -
a. Computer can't decide
b. Computer can't think
c. Computer can't express ideas
Example:
We entered the age of two persons as 25 and -15. Now, we have programmed to compare these data values to display the smaller number. Obviously, it will display as -15 is smaller. But, -15 is an invalid number to compare age. Thus, a computer can't justify that age of a person can't be a negative number.Lesson 2 - Types of Software
