Use of Computers in Business

The Information Technology (IT) revolution that brought in computers has gone through a variety of stages. The prominent introduction being in the 1960s, when big companies had to store large amounts of data. The revolution of computers initially was used for complex data bases only. However, people realized the many uses that computers had to offer to everyone for daily use. Two major breakthroughs were the introduction of PCs and Mac computers, which of course greatly facilitated businesses and working people in several ways. Apart from that, hardware such as scanners, CDs, floppy drives, and printers, have facilitated the operations of offices in a big way.

All-in-one Device
Earlier, before computers were introduced in businesses, there were multiple devices in offices such as fax machines, typewriters, telefax equipment, stenography equipment, and filing cabinets that were used extensively. Computers successfully replaced all these office tools. The entire office became ‘dematerialized’, which also resulted in the optimum use of the available space.

Accounting and Finance
A computer is a clever accountant. There are countless accounting software that can cleverly record entries and plan finances. These financial software basically increase the accuracy and efficiency of the accounting process. There are also several Internet banking facilities that have come into use in recent times. Such facilities enable people to conduct transactions from their offices, saving them a journey to the bank.

The Internet and the concept of emails has benefited businesses immensely, as information, letters, graphics, applications, and almost any sort of communication can be transmitted from person to person, at distant locations, in a matter of seconds. The Internet also helps in communication to the masses. Stock investors, Forex traders, media companies, financial planners, and company owners rely heavily on electronic communication for instant transfer of information.

Technical Software
Technical software are used by countless people worldwide, such as engineers, architects, logistics personnel, etc. These software are user-friendly, accurate, convenient, and fast. A multitude of things can now be done and created with the help of computers, like designs, graphics, blueprints, program codes, etc.

In today’s world, it is easy to prepare documents and create presentations. Decades ago, these would take weeks, if not days, to be completed. Due to everything being computerized, important documents and presentations can be completed in a matter of hours, acting as a catalyst for various business processes.

Gone are the days when one needed to go to a library and search through shelves of books to get some information. Nowadays, when an organization needs some information, it’s available at the click of a button. It also allows business to get updated information about competitors, suppliers, customers, and the like, which obviously helps in the better running of any business organization.

Unlike olden times, information and data storage now takes up hardly any place. Gone are the days when offices needed large storerooms in order to store hundreds of files of important data. Computers and servers have allowed us the luxury of storing much more data in much less space.

Computers are something we take for granted nowadays. Little do we realize how this device has made life so much easier, both on the personal and professional front.

Internet is a much larger and easier-to-access storehouse of information. When it comes to storing retrieved information, it is easier done on computers than maintaining hand-written notes.
Computers Gave Impetus to Distance Education
Online education has revolutionized the education industry. Computer technology has made the dream of distance learning a reality. Education is no longer limited to classrooms. It has reached far and wide, thanks to computers. Physically distant locations have come closer due to Internet accessibility. So, even if students and teachers are not in the same premises, they can very well communicate with one another. There are many online educational courses, whereby students are not required to attend classes or be physically present for lectures. They can learn from the comfort of their homes and adjust timings as per their convenience.
Computers Improve Presentation of Information
Computers facilitate effective presentation of information. Presentation software like PowerPoint and animation software like Flash among others can be of great help to teachers while delivering lectures. Computers facilitate audio-visual representation of information, thus making the process of learning interactive and interesting. Computer-aided teaching adds a fun element to education. Teachers hardly use chalk and board today. They bring presentations on a flash drive, plug it in to a computer in the classroom, and the teaching begins. There’s color, there’s sound, there’s movement – the same old information comes forth in a different way and learning becomes fun. The otherwise not-so-interesting lessons become interesting due to audio-visual effects. Due to the visual aid, difficult subjects can be explained in better ways. Things become easier to follow, thanks to the use of computers in education.

Internet has information on literally everything and computer technology enables easy access to it. Internet can play an important role in education. As it is an enormous information base, it can be harnessed for retrieval of information on a variety of subjects. The Internet can be used to refer to information on different subjects. Both teachers and students benefit from it. Teachers can refer to it for additional information and references on the topics to be taught. Students can refer to web sources for additional information on subjects of their interest. The Internet helps teachers set test papers, frame questions for home assignments and decide project topics. And not just academics, teachers can use web sources for ideas on sports competitions, extracurricular activities, picnics, parties and more.
Computers Allow Efficient Data Storage
Computer hard drives and storage devices are an excellent way to store data. Computers enable storage of data in the electronic format, thereby saving paper. Memory capacities of computer storage devices are in gigabytes. This enables them to store huge chunks of data. Moreover, these devices are compact. They occupy very less space, yet store large amounts of data. Both teachers and students benefit from the use of computer technology.

The process becomes paperless, thus saving paper. Plus, the electronic format makes data storage more durable. Electronically erasable memory devices can be used repeatedly. They offer robust storage of data and reliable data retrieval.
This was about the role of computers in education. But we know, it’s not just the education sector which computers have impacted. They are of great use in every field. Today, a life without computers is unimaginable. This underlines the importance of computer education. Knowledge of computers can propel one’s career in the right direction. Computers are a part of almost every industry today. They are no longer limited any specific field. They are used in networking, for information access and data storage and also in the processing and presentation of information. Computers should be introduced early in education. It won’t be an overstatement to say that computer education is as fundamental as learning English. Yes, it is.

Uses of Computers in Space Exploration

Uses of computers in space explorationDid you know?
It would be impossible to have the Hubble Telescope in space, had it not been for the advancement in computers and space technology. The James Webb Space Telescope (JWST), which will succeed Hubble, will be launched soon, which is accompanied by advanced computer systems and software, that will help us further reveal the enigmas of the universe.
Computers have led to major advancements and breakthroughs in space research. Every aspect of space technology, be it designing a spaceship, its control and navigation, or compiling and processing data, has all been done by computers. The complicated arithmetical computations needed to fly spacecrafts, monitor the work of astronauts in space, keep them alive, and analyze as well as interpret the collected data, would be extremely difficult and take a long time, if not for computers. In fact, computer technology and space research have grown together, to take astronomy to new heights, wherein we are able to unravel some of the numerous mysteries of the universe.
Getting Into Space
Designing the Spaceship
Computers help design the aircraft which is made from equipment that is customized and highly sophisticated. This spacecraft has to endure various threats, and numerous technicians and engineers plan its design and working very minutely. After the spacecraft is built, it is run through many automated tests, which are created by computers to simulate cold, vacuum, and vibrations, that it will encounter in space. Once it passes all these tests, it is ready to be launched.
Planning and Preparation
Space missions need accurate planning and calculations of the trajectories, propulsion, and path that a space vehicle will take. It must be defined precisely after considering the motions and gravitational forces of various celestial bodies. The time, amount of fuel, duration of the mission, everything needs to be exact. Even a millisecond of miscalculation can prove disastrous. Considering all this, computers are used to carefully plan and prepare the mission.
The craft has in-built software for diagnostic tests and updates, that are constantly run to check the status of the equipment. If encountered with a problem, it reports it to the team on Earth, which will give or suggest a solution to that problem and get it solved. Many problems would go unreported, if not for computers, which could prove disastrous to the mission.
Placing a spacecraft at the exact accurate position, its trajectories, etc., all need to be precisely calculated. It is done in three dimensions. The engines that need to fire up, their time and duration, are all taken care of by computers. The navigation of the spacecraft and keeping a spacecraft on its course is something that computers monitor and keep in control 24/7.

Imaging and Space Photography

Computers, with the help of large telescopes, capture high quality images of planets, the Earth, moon, asteroids, stars, comets, galaxies, other celestial bodies, and unknown matter that exists within the universe. Digital photography has changed the ways of astronomy, as we can alter the images and colors, use filters and satellite information to view the images more clearly. It is possible to enlarge images and see more than we could with our naked eyes. The famous Hubble Space Telescope, which was launched by NASA in 1990, continues to transfer thousands of images of the cosmos to Earth, with the help of computers. If calculated, 120 gigabytes of data is what we get from the Hubble Telescope, every week.
Data Analysis and Storage
Research data is so vast and huge that, manual storage of this data would take years. Computers play a vital role in the compilation, storage, and sharing of this information. This technical information is collected, organized, and maintained effectively by computers, for scientists to be able to stay updated and gather real-time information all around the world. Various astronomical phenomena like black holes, quasars, or even sunspots, have unique signals and patterns. Computers sift and sort out data regarding these patterns on their own, so that the work of space explorers becomes easier.
Communication and Robotics
Communication with the mission craft is done with the help of computers. Keeping in touch, transferring data, power management, motion, movement, sending and receiving new data or programming, is all done with the help of computers. The robots or rovers that are sent on a space mission are manipulated, controlled, and guided by computers.
Life Support for Astronauts
The living conditions and environmental control systems of a spacecraft use computers to monitor the devices that keep the atmosphere in the spacecraft healthy and liveable. The humidity controls, oxygen sensors, carbon dioxide purifiers, thermostats, and other devices, are kept in check by the computers. If any problems arise, the crew is immediately alerted, and the problem is rectified.
Constant Vigilance
Computers constantly monitor objects like satellites, rockets, debris, etc., which revolve around the Earth. They keep a track, detect, and help identify various celestial bodies that orbit Earth. They help catalog the data sent by various surveillance satellites and space control centers.

The United States Space Surveillance Network (SSN) contains powerful radar sensors, highly effective computers, and tracking devices, that are constantly on the watch, and send and receive a steady flow of information from the satellites and centers.
