Computers are perhaps the greatest invention in the field of microelectronics that has suited well with the advancement in the new century . They have moved centre stage in the achievement of major operations world over with their use in every aspect of life . Computers are the building blocks to the resent advancement in knowledge creativity and invention . Through use of computers designs have been manufactured and so much has been learnt through the use of computers . The invention of personal computers and microprocessors is unique in its integrated circuit and ability to process diverse tasks and provide memory circuits for them .
They are able to carryout arithmetic operations data analysis , operating instructions and managing data flow among others . This has gone along way in reducing human involvement in manual operations . This is especially because programs can be installed to carryout different operations and store the data accordingly .
Computers are efficient , accurate and reliable to use and provide a learning opportunity in the current environment of change in technology , competition and discoveries . In the medical field , computer programmes have been used to analyze DNA structure (genetic make up ) of human beings , disease causing agents as well as other living organisms . Automated machines have also been made to carry rast number of tests accurately and efficiently . They also have standard control procedures and programmes that maintain quality of results and accuracy of results . Though there has been other invention in the recording and communication there has been advancement use of codes to protect information .
It advanced to automated decoding and decoding modern machines is a telephone and telegraph company in America where Gilbert S . Venam two tape readers and a cipher text encode and decode information . Automatic translation of text has been made possible today by use of computers . Furthermore more controls could be introduced and a multi user computer can perform this task . In the past manual conversion used old machines that posed a challenge in reading secret codes whereas the modern computer can serve to convert information to give a representation of an output in a simple , obvious and reversible manner . The information can also result to the comples or obscure to convert or may be secret or irreversible hence a computer results to being an encryption machine .
The computers have immense power with great performance . It has become cheap and easy to use in automatic coding and encoding and protection of data . In this century the effect of globalization has resulted to internet shopping through a phenomenon called e-commerce . The computers have been used to complete transactions via the internet and this has made business penetrate all nations of the world . Passwords have been used to protect information on a product or webpage and this has also served to protect the posed great challenge due to internet fraudsters who have been able to access and manipulate information for their selfish gain
