How computers have changed our lives.

computersComputers are perhaps one of the most remarkable innovations in human existence. Needless to say that the computers themselves have come a long way and have greatly changed from what they previously were to remarkable pieces of technology that affect our lives in various dimensions.

Influence of computers in education.

The education arena has come to new levels as computers have largely impacted how we share information and learn. You can find answers to virtually any query that you ay have. It is also easier to connect to other people in the globe and share in their learning experience. There is also easier storage of information and access to resources which has made education more fun.

Computers and utility facilities.

Tremendous improvements have been witnessed in our lives. Transportation, water, electricity and other things that make for convenience have greatly been improved by computers. Computerization has made everything efficient and delivery of essential services is no more a daunting task.

Health care.

Medical care has greatly been improved thanks to the inception of computers in the health sectors. Data management systems are crucial for hospitals. Doctors and other medical practitioners have access to valuable information that touches on patients. This enables efficient delivery of medical services and also better response to emergency situations.
Tremendous improvements have been made possible in surgical theatres. Computers aid surgeons in mapping of the areas that are to be operated upon. Signs of the vital organs are monitored by use of computers. Surgeons are known to use conferencing facilities to share with others on different parts of the globe and come up with solutions in the event of complexities.


The world can be said to be a lot safer, thank to computers. Computer technology has made it possible to improve on security systems. Law enforcement agencies can respond to emergencies faster, thanks to better communication and alert systems that have been made possible by computers.
Homes, businesses and streets are a lot safe, security …

Modern Hacker Threats.

wp-content-uploads-2012-02-online-hacking-threat-more-pervasive-than-everThe revolution in the ICT industry has do much good in how we handle business and even communicate. The computer, tablet and mobile phone have become a window to the globe if not the universe. In all this blessing, there is someone who has malicious intent to make sure that they internet is not as safe as anyone would want it to be. I am not talking about the online pervert who is geared towards corrupting morals. It is the hacker I am talking about here. With cloud computing becoming the trend in the ICT arena, the threat is even bigger.

There are many threat methods that hackers use to pose threats to internet users. Three major categories however are:

  • Buggy programs.
  • Unsafe programs.
  • Misconfigured programs.

Buggy programs.

Buggy programs are the kind of programs that are designed and properly configured but have flaws in the implementation and coding aspects. This is what gives leeway for the hacker to remotely exploit your system. There are two ways to this; parsing errors and buffer overflows.

Buffer overflows are errors in programing where the program writer creates a buffer to store remote input data without checking on the length to see whether it fits well. A hacker can then send more data to the buffer which will include malicious executable data that gives the hacker access to your machine. Parsing errors on the other hand occur when the contents of remote input data aren’t properly checked. This happens when a web server allows a hacker to view html files that are not allowed to be viewed. Here, the hacker gets access to information like usernames and passwords which are then used maliciously.

Unsafe programs.

These are the kind of programs that are generally unsafe for use in the internet due to their design. These are easily exploited by hackers as they either send the username and passwords unencrypted over the internet or use IP addresses of users for verification. This information …

Technology and Economic Growth

Tech2Technology is inarguably one of the fastest growing industries both locally and in the global economic arena. With many counties adopting policies and building frameworks that will enable then remain competent and relevant, growth in this industry has yet to reach unimagined limits. Technology, especially information and communications technology, has brought a shift to the economy with the benefits and positive effects being seen in all levels. Lives are changing and better standards of living and trade are being realized. The common benefits are:

Job creation.

The technology sector, more so ICT is one of the biggest direct job creation avenue. By 2020, there is an expected growth of computer and information technology jobs by 22.5%, which is well over 700,000 jobs. For every job created in the technology industry, there are additional 6-7 jobs created elsewhere. This will definitely come with increased salaries and a wider range of products and services.

Contribution to GDP growth.

Technology has a huge contribution on the growth of the Gross Domestic Product in various countries. If we take a look at ICT for instance, an increase of 10% in penetration of broadband translates to a 1.5% increased GDP growth in emerging markets. Globally, this increase in connectivity, especially in the 3G platform has paved way for a 0.57% GDP growth. This growth has been spurned by growth in the SME and e-commerce.

Emergence of new industries and services.

Technology has seen the rise of more products and services in trade. As a matter of fact, more products and services have become more and more digitalized and available in the internet. The inception of cloud computing is one of the hall marks of modernization. Emergence of the App industry for instance is purely technology based and has been made possible by the Information Communication Technology. From banking to conferencing, from ordering for services to mobile money transfers like M-Pesa in Kenya, there are numerous way in which technology has seen the birth of products …
