A computer is an electronic device that store, process and display information and data in a form that is easily understood. The main characteristics of a computer are the very high speed with which calculations and processes are carried out and also the very large amount of information and data that may be stored in a relatively small spaces called memory. Computer has made a very vital impact on society. It has changed the way of life. The use of computer technology has affected every field of life. People are using computers to perform different tasks quickly and easily. The use of computers makes different task easier. It also saves time and effort and reduces the overall cost to complete a particular task. Many organizations are using computers for keeping the records of their customers. Banks are using computers for maintaining accounts and managing financial transactions. The banks are also providing the facility of online banking. The customers can check their account balance from using the internet. They can also make financial transaction online. The transactions are handled easily and quickly with computerized systems. See Also : Right technology for kids at every age People are using computers for paying their bills, managing their home budgets or simply having some break and watching a movie, listening to songs or playing computer games. Online services like skype or social media websites are used for communication and information sharing purposes. Computer can be used as a great educational tool. Students can have access to all sort of information on the internet. Some great websites like Wikipedia, Khan’s Academy, Code Academy, Byte-Notes provides free resources for students & professionals. Moreover, the computer is being used in every field of life such as medical, business, industry, airline and weather forecasting. Introduction
Advantages of Using Computer Speed of Computing Efficiency and Productivity Data Storage
Speed of Computing One of the main advantages in using computers is the possibility that a task that may take longer to do by hand may be done in a shorter period of time using a computer. Computers are designed to do tasks much faster and more accurately than humans. Numerical computations, creation and editing of documents, data organization and presentation, graphics are examples of tasks that are done efficiently when computers are used.
Efficiency and Productivity It is perhaps easy to explain the efficiency of computers in comparing documents produced using a typewriter and a word processor (on a computer). Using a word processing makes it easy to make changes to letters, words, chapters or entire documents. There are possibilities to spell check words and therefore make changes. Deleting and inserting letters, words and paragraphs is done without leaving a trace. When all necessary changes are made, files may be saved, printed, edited as many times as is necessary, sent by e-mail to someone else in another continent within minutes. When using a typewriter, a simple typing error would be time consuming to fix. Several recent studies have shown a substantial increase in productivity due to the use of computers.
Data Storage. Computer storage or memory is measured in bytes. A byte correspond to 8 bits (binary digit). For example it takes 1 byte (or 8 bits) to represent (store) a character of the alphabet. A page of a book with 80 characters per line and 40 lines per page would need 80 * 40 = 3200 bytes of storage or 3 Kilobytes (1 Kilobyte = 1024 bytes). A book of 400 pages would need 400 * 3 Kilobytes = 1. 2 Megabytes (1 megabyte = 1000 Kilobytes) What does all this mean in practical terms? Example 1: A CD has a storage capacity of 600 Megabytes and therefore can hold the contents of 600 / 1. 2 = 500. Yes 500 books in ond CD!. Example 2: A DVD has a storage capacity of 4. 7 Gigabytes (1 Gigabyte = 1000 Megabytes) and can therefore hold 4700 / 1. 2 = 4000 (approximately) books. Now think about how much space and how much does it cost to store 4000 books!
The main advantages of computers 1. More informati on sources 2. More opportunities for cooperation and networking 3. Increased access to the information stored in the resource centre 4. Increased efficiency 5. More services
1. More information sources — A computer with a CD-ROM drive can provide access to materials stored on a CD-ROM, including databases (containing descriptions of materials) and full-text (complete) materials. A computer linked to a modem can provide access to information available via e-mail and other Internet services, such as electronic newsletters and websites. 2. More opportunities for cooperation and networking — A computer linked to a modem makes it easier to communicate with other resource centres, via e-mail. Sharing information among different resource centres can improve users’ access to information and cut down duplication of effort. 3. Increased access to the information stored in the resource centre — The main way to search for materials using a catalogue card system is by author, title, and a limited number of keywords. To add more keywords or other details would require more cards. This would require more work, and the catalogue would become larger and more difficult to keep up-to-date. 4. Increased efficiency — Information stored on a computer database can be used for different purposes. For example, details of materials entered onto a database when ordering them can be used for a catalogue, simply by adding classification numbers and keywords. The same records can be used to produce current awareness bulletins or resource lists. 5. More services — A computer can be used to ‘repackage’ information held on a database, in the form of directories, resource lists or current awareness bulletins. Information held on the computer or available via the Internet can be adapted to produce locally relevant materials.
The usage of computer gives following advantages in comparison to manual Speed. Accuracy. Versatility. Reliability. Storage. Automatically Compactness Repetitiveness For this, the company has to do only three things: Prepare address database. Draft a letter. Merge the database Diligence No Feelings
Advantages of Computers • Speed Up Work Efficiency This is by far the biggest advantage of using computers. They have replaced the use of manpower in carrying out tedious and repetitive work. Work that can take days to complete manually can be done in a few minutes using a computer. This is made possible by the fact that data, instructions and information move very fast in the electric circuits of computers. They process trillions of instructions within a second.
Large and Reliable Storage Capacity. • Computers can store huge volumes of data. To put this into perspective, physical files that can fill a whole room can be stored in one computer once they are digitized. Better yet, access to the stored information is super-fast. It takes micro-seconds for data to be transferred from storage to memory in a computer. The same cannot be said for the retrieval of physical files. With a computer, you can store videos, games, applications, documents etc. that you can access whenever required. Better yet, storage can be backed up fast and efficiently.
Connection with Internet. • The Internet is probably the most outstanding invention in history. Computers allow you to connect to the Internet and access this global repository of knowledge. With the Internet, you can communicate faster with people across the globe. You can send email, hold voice and video calls or use IM services. The Internet also allows for instant sharing of files. You can also connect with friends and family on social networks and even learn a new language online. The Internet is a great educational resource where you can find information on virtually anything.
Consistency • You always get the same result for the same process when using a computer. For example if you created a document on one computer, you can open it on another without making any special adjustments. This consistency makes it possible to save and edit a document from different computers in different parts of the world. Collaboration is therefore easier. Whatever job you need done, you can always rest assured that the computer will get it just right. There will be no variations in results achieved from the same process. This makes computers ideal for doing tedious and repetitive work.
Сonclusion • Computer can be used as a great educational tool. Students can have access to all sort of information on the internet. A computer is an electronic device that store, process and display information and data in a form that is easily understood. Speed of Computing: One of the main advantages in using computers is the possibility that a task that may take longer to do by hand may be done in a shorter period of time using a computer. Efficiency and Productivity: It is perhaps easy to explain the efficiency of computers in comparing documents produced using a typewriter and a word processor (on a computer). Versatility: Previously, the computer was thought as only a calculating machine, but a computer cans also carryout logical operations. More information sources — A computer with a CD-ROM drive can provide access to materials stored on a CD-ROM, including databases (containing descriptions of materials) and full-text (complete) materials.
