Benefits/Advantages of ICT in Education
General Advantages of ICT
1. Time Saving
With ICT, the time it takes for messages or information to be sent and received has been considerably reduced. Correspondence between people and organisations all over the world is now instantaneous. The moment a message is sent, it is received immediately and action taken on it with little or no delay. This, in computing, is referred to as Real lime. Also, information on any subject can be easily accessed through the World Wide Web (www) on the Internet.
2. Money Saving
ICT has helped in saving money. The money that could have been spent in
moving information through transportation and copying or duplicating materials is saved. Money is also saved when many computers use the same equipment like printers, scanners, etc. ICT has made this possible. Getting access to information is also not expensive.
3. Storage of Data and Information
Data and information can be stored in a single place, making it possible for
those data and information to be accessed easily.
4. Training of Large Numbers of People
A large number of people separated by distance can be trained at the same time at the possible time.
Some jobs can be done at the comfort of one’s home. A teacher can teach or
lecture his students without leaving his home or office or having to meet his students face to face in a classroom. Business can be transacted from the home or office with ease. This is referred to as e-commerce

For one to enjoy the benefits of ICT, one must have access to a computer and the Internet. These facilities are very expensive to purchase at present. This has therefore prevented many from having access to the benefits of ICT, especially in less developed countries.
2. Servers Breakdown
When a server develops a fault or fails to function properly, it will affect the
application of all other computer systems that it controls, or supplies
information to, and there may be thousands of them. A server is the main computer which runs the program on which all the other computers in a network are linked. When a server breaks down, it becomes difficult to retrieve information from other computer systems.
3. Danger of Virus Spread
A virus is hidden programming instructions within a computer program which can damage or destroy data files. It can spread from one computer to the other. Information that has been stored in a computer can be lost or destroyed, and if the information is very useful and vital it may not be found again.
