Data and Communication Technology (ICT): Information is for the most part utilized as an equivalent word for data innovation. Truth be told, data and correspondence innovation is a type of coordinated correspondence framework [1] and a framework comprising of media transmission, PC arrange related venture programming, middleware information stockpiling, sound video frameworks, and so on., through which a client can without much of a stretch take, save, run and break down data. you can do. In the 1980s, scholastic analysts started utilizing the term ICT in innovation. Yet, the word has picked up prominence since 1997. Stevenson specified this word in a report given to the UK government in 1997, which was later added to the UK's new national course book in 2000. 
At present, information and correspondence innovations are discharged through a solitary or single connection framework, phone, varying media and PC organize mix innovation. The mix of phone, varying media and PC organizes through a solitary connection framework has decreased tremendous measure of financial cost.
Data and Communication Technology Sectors: Data Protection Technology. Data trade or data correspondence (media transmission, PC arrange, web and so on.) Technology. Information preparing innovation. Spare and supply the right data.
Data and correspondence innovation materials, equipment, programming, information, talented labor, systems!
ICT in the worldwide economy: At show, the worldwide cost of ICT has been set at $ 3.5 trillion and consistently it is expanding by 5%. The cost of this cost is multiplying at regular intervals.
The level of aggregate spending utilization in various zones of ICT is as per the following
31% - Personal costs (Internal) # 29% - Software division spending (External). # 26% - equipment costs (outer). # 14% - External specialist co-ops.
The ICT Development Index thinks about and arranges support in ICT use and ICT worldwide.Role of ICT in the field of training
As a rule, training disapproved of individuals, coordinators and specialists concur on the great impact of ICT in the field of instruction. What is still discussed is what amount complex utilization of ICT ought to be utilized as a part of training and the amount it should be possible in reality.In antiquated circumstances, it was known as (I) that implies data or data. At the point when individuals went chasing, they would have been chasing and chasing for data on the best way to do the chase, how to do the chase. The time of farming comes after the time. In this time, they gathered data about farming. Step by step instructions to sow the seeds of the product, to gather crops whenever. At that point the general population assembled data about how to reap crops.
In the consequent years, innovation or innovation was utilized to gather the data got. Distinctive sorts of innovations are accessible with the assistance of innovation to hold data through different means. The utilization of innovation for handling, repairing, and saving data expanded. This period can be considered as its time or data innovation. Once in Bangladesh, this brilliant time of IT instruction is winning. The impact of this was to create like an umbrella of the nation after one IT training school. Particularly the period of private college of our nation is made by the focal point of this IT training. In excess of one private college is produced by the name of PC training. Thus, in a couple of years the nation was loaded with PC specialists.
They were specialists in making different sorts of programming on PCs, yet our nation was not prepared to make appropriate fields for them. Therefore, those PC specialists need to fill in as general PC administrators. Where they worked, writing, creating, computing, altering photographs, dealing with huge database administration. Truth be told, it is still addressed whether the PC was required to have a higher degree for this reason.
Afterward, in the present day, IT has been related with IT correspondence. Speaking with IT built up a conviction that opened to everybody another skyline. Data and correspondence innovation created with the help of information availability, free access, and so on. It is ordinarily used to convey or impart data utilizing innovation, data and correspondence innovation. What's more, for this reason, development is being imagined for different sorts of innovation items. These information are being taken on account of the general population, so the correspondence is getting to be simpler and less demanding.
Data and correspondence innovations are being identified with our instruction, at that point we are seeing two essential issues-
(1) Information and correspondence innovation instruction and
(Ii) Education Information and Communication Technology. 
Numerous individuals combine these issues. In any case, the two things are totally unique. The first is viewed as a subject, for example, material science, general arithmetic, and so forth. The second is to utilize data and correspondence innovation amid perusing. In our present training strategy, data and correspondence advancements have been brought into the field of instruction. In continuation of this, the legislature has included another point in the 6th grade as a subject called Information and Communication Technology Education. How about we now observe, what is the contrast amongst data and correspondence innovation or ICT instruction and ICT in training?
In straightforward words, when ICT will be talked about, what is the data, how to impart, how to convey utilizing certain parts, utilization of innovation items will be the ICT Education. Once more, ICT alludes to showing things like utilizing ICT instruction, for example, demonstrating a toon picture and giving a message about something. At display, we see some more employments of ICT in instruction, for example, instructive sites, savvy classroom, e-library, showing English through versatile, taking classes through video conferencing, understudy database administration etc.The distinction between these two angles infers that ICT training will be required for the understudies and the utilization of ICT in training will be utilized by instructors, teachers. The inquiry is, the thing that will be the educational programs of ICT instruction, how to educate in a class, and so forth. It might be said in this setting a class educational modules is planned, thinking about the capacities of the understudies of the class, age, intelligent people and so on. For the most part, educational modules is set up in our nation, it is shown well ordered in all classes in a phyllonic approach to instruct in a winding framework. For instance, finding out about water is instructed in the second rate class water. The fourth class is instructed where to discover water sources or water. In the fifth grade, the components of water are educated. Along these lines venturing from profound to profound is ventured. This can be remembered about the age of the understudies and their ability.
We can likewise utilize this technique for ICT training. For this situation we can give the essential thought regarding the ICT enter in the 6th grade, its idea, PC contact and so on. At the progression we can take ICT instruction towards IT. As it is about different issues. For instance, an area of the second rate class general science, water content instructed in the following evaluation of water is educated at one time as a feature of science in Eleventh Class XII. So also, we can give the fundamental training of data and joint effort innovations to the media. Which can later appear as PC training in Eleventh Class XII. By doing this, it will be useful for the understudies to lead the path towards advanced education. Along these lines, the understudies will get fundamental instruction in the medium of data and innovation. They will likewise have the capacity to begin on PC and can be PC proficiency. There is no should be a PC master on all understudies till the auxiliary level, however there is sufficiently just broad abilities in software engineering. It might be viewed as that if the PC instruction book is available in the ninth grade, it can be incorporated into the training of data and correspondence innovation, yet it will be useful for the understudies to build ICT aptitudes. Thinking about these angles, it is important to incorporate data and correspondence innovation instruction constrained to PC training as well as to incorporate different things too.
