Abstract: A computer cannot do any work on its own. It depends on the logical sequence of instructions to perform any function. This logical sequence of instructions is termed as a 'computer program', and it is a part of the computer software. Basically, the sequences of instructions are the algorithms that step-wise instruct the computer what to do. Hence, a computer cannot work without software. The term 'software' was first used in print by John W. Tukey in 1958.There are various types of software designed to perform specific tasks. The different types of computer software are interpreter, assembler, compiler, operating systems, networking, word processing, accounting into a machine language so that the computer can execute it.

Abstract: Memory is used for storage and retrieval of instructions and data in a computer system. The CPU contains several registers for storing data and instructions. You The basic input/output devices, such as keyboard, mouse, light pen, etc. The computer system is a dumb and a useless machine if it is not capable of communicating with the outside world. Memory is used for storage and retrieval of instructions and data in a computer system. The CPU contains several registers for storing data and istructions. But these can store only a few bytes. If all the instructions and data being executed by the CPU were to reside in secondary storage like magnetic tapes and disks and loaded into registers of the CPU as the program execution proceeded, it would lead to the CPU being idle for most of the time, since the speed at which the CPU processes data is much higher than the speed at which data can be transferred from disks to registers. Every computer thus requires storage space where instructions and data of a program can reside temporarily when the program is being executed. This temporary storage area is built into the computer hardware and is known as the primary storage or main memory. Devices that provide backup storage are called secondary storage or auxiliary memory.

Abstract: A number is an idea that is used to refer to amounts of things. People use number words, number gestures and number symbols. Number words are said out loud. Number gestures are made with some part of the body, usually the hands. Number symbols are marked or written down. number symbol is called numeral. The number is the idea we think of when we see the numeral or when we see or hear the word. You must be familiar with the decimal number system, which is well known as the base 10 number system. Some call its positional number system since the values of the numbers are decided by the position of the values, like units, decimals and hundreds. In other words, the value of the number is determined by multiplying each digit by a weight decided by its position and then adding the individual products. The weight is decided by the location as well as the base in which you want to represent the number.
There are four systems of arithmetic, which are often used in digital systems. These systems are: In any number system, there is an ordered set of symbols known as digits. Collection of these digits makes a number which in general has two parts, integer and fractional, and are set apart by a radix point(.).

Abstract: A computer is machine that manipulates data according to a set of instructions. The ability to store and execute a prerecorded list of instructions called programs makes computers extremely versatile. Hence, it is programmable electronic device and responds to a specific set of instructions and performs high-speed processing of numbers, as well as of text, graphics, symbols and sound. Modern computers are electronic and digital. The Central Processing Unit (CPU), wires, transistors, circuits, memory, peripheral devices, etc, are called hardware, while the instructions and data are software.
Technically speaking, a computer is a programmable machine, which executes a programmed list of instructions and also responds to new instructions that are given to it. Basically, computers are of three types, digital, analog and hybrid. The digital computer stores data in discrete units and performs arithmetical and logical operations at very high speed. The analog computer has no mercy and is slower than the digital computer but has a continuous rather than a discrete input. The hybrid computer combines some of the advantages of digital and analog computers.

Abstract: Nilgiris district promotes horticulture and landscape development for ill cultivation vegetables, mainly carrot, Potato, cabbage, cauliflower, radish, beet and legumes.IN 1603, Portuguese Priest Mr Finici described the traditional mixed land farming practices, which were extensively followed by the indigenous community Badagas in Melkundha village of Nilgiris. The community farmers cultivated important crops such as small millet, legumes, and leafy vegetables. Then, they started to grow mustard, wheat, and garlic in their mixed hill cultivation practices (Rajasekaran, 2015.)

Subject: Digital Morphometrics of Leaf Shape and its Application to Species Differentiation in some Species of Argyreia Lour. (Convolvulaceae)
Keywords: Morphometric analysis, Elliptical fourier descriptors, Leaf shape, PCA.
Abstract: Genus Argyreia belongs to the family Convolvulaceae and comprises flowering plants commonly known as silvervine or elephant creeper. These plants are native to tropical and subtropical regions, including parts of Africa, Asia, and Australia. Argyreia species are known for their large, attractive flowers and are often cultivated for ornamental purposes. Argyreia plants typically have simple and alternate, large, broad leaves. The leaves can vary in shape, often being ovate or cordate, and have prominent veins. Morphometric analysis of the leaves of eight (8) species of the genus Argyreia was carried out using Elliptic Fourier Analysis (EFA). Principal component analysis (PCA) was performed based on variance-covariance matrix. Resulting PCs are utilized to create a dendrogram via neighbour joining method using Euclidean distance. The dendrogram revealed three major groups among the presently analysed species of Argyreia. Group-I was comprised of four species i.e., A. pilosa, A. nervosa, A. boseana and A. sharadchandrajii. A. setosa, A. sericea and A. elliptica formed the second group. Due to different leaf shape A. cuneata has been placed in last group. Present study reveals the importance of morphometric analysis in species differentiation based on leaf shape and structure and can be used as additional identification tool when combined with other methods.

Subject: Fuelwood Burning : Utilization Trends for Forest Sustainability in the Cold Desert of Trans Indian Himalaya
Keywords: Trans-Himalayas, Fuel wood, Energy, Resource use index, Lahaul valley.
Abstract: In the Indian Himalayan region, heat energy consumption in terms of fuelwood is always given importance. This study has highlighted qualitative and quantitative consumption trends of fuelwood species utilized by people in the Lahaul Valley, a cold desert in the Trans-Indian Himalaya. For each plant species, the average quantum collection, probability of utilization, and Resource Use Index were assessed. The study revealed a diversity of 42 fuelwood species used by the tribal population. Among all the species, maximum Resource Use Index value and preference were recorded for Salix fragilis, followed by Juniperus polycarpos, and Pinus wallichiana. The study also highlighted the available stock of fuelwood species. In recent years, consumption pressure on fuelwood from the forests showed a declining trend, it could be the adoption of sustainable harvesting practices which will save energy by burning fuelwood. Of the total species, the higher dependence on native species (57.14%); near-endemic species (30.95%); and endemic species (2.38%) were recorded, this indicated the importance of these species for conservation. Hence, regular monitoring for extraction trends with changing attitudes of the people is required.
