1. Blockchain Technology: Blockchain is a distributed ledger technology that lets data to be stored globally on its servers and it is based on a P2P topology which makes it difficult for someone to tamper with the network.

It can be used as a cryptocurrency wallet that supports BitCoin, Ethereum, etc.

An advantage of it is that it is distributed among several users and stable.

A disadvantage for a developing country like Ghana is that once a blockchain is sent, it cannot go back which brings up the question of security.

2.Artificial Intelligence: This technology is simply the simulation of human intelligence in machines. AI can be used for problem-solving and learning. An advantage of AI is that it reduces human error and is fast in solving problems. A disadvantage of AI is that its expensive to maintain and also it does not improve with experience.

3. Global Positioning System: GPS is a satellite-based positioning system that is used to pinpoint and track location. It has the advantage of being available worldwide and information is provided to users in real-time. One disadvantage of the GPS for a developing country like Ghana is that electromagnetic interference can affect the accuracy of the GPS.

4. 5G Network: This is the 5th generation of mobile internet connectivity that gives super fast download and upload speeds when compared to its predecessors 4G, 3G, 2G, and Edge networks.

One major disadvantage of 5G for a developing country like Ghana is that it is expensive and quite unknown and its security and privacy issues are yet to be resolved.

5. Lasers: This isn't a new technology as it has been in use for some time already but its importance cannot possibly be over-emphasized. LASER is an acronym that means Light Amplification by the Stimulated Emission of Radiation.

It is precise and accurate in cutting when compared to thermal and other conventional cutting methods. It is being used in surgeries that require the highest levels of accuracy with great success.

A disadvantage of Laser technology is that it is expensive to use and maintain.

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
