Many UK businesses whether big or small, depend greatly on American District Telegraph (ADT) or simply ADT, Closed Circuit Television (CCTV) and Digital Video Recorders (DVR) as a source of integrated electronic security system. Tesco is one of those convenience supermarkets that depend highly on the services provided by the above security systems.

These security systems provide fast alarm responses to burglary, fire attacks, violence and unnecessary disturbances in Tesco.

These security systems reduce a safe and convenient environment for Tesco customers.

They help reduce crime wave, protect people and property.

Tesco also applies the use of security codes in their online services. This is to ensure that the online customer placing the order is actually in possession of a credit/ Debit card and that the amount of money in the card is legitimate.

Plus, we run training sessions on formatting and academic writing to keep their skills sharp. You’ll get to chat with your writer through a handy messenger on your personal order page. We’ll shoot you an email when new messages pop up, but it’s a good idea to swing by your page now and then so you don’t miss anything important from them.

According to Nicholas Carr, the strategic importance of information technology is diminishing as it has become standardized and less expensive.

Issues against Cloud Computing.

Although cloud computing is a less expensive system of computing, enterprises may pay more on operating expenses.

Cloud computing has been highly criticized for its lack of privacy between users and their hosting companies. They hosting companies may monitor at will the communication and data stored in their systems. For example the National Security Agency (NSA) that works with American Telephone and Telgraph (AT & T) and Verizon Communications, monitors all their phones which make people insecure for lack of privacy.

There is no security in cloud computing but the Cloud Computing Alliance has been form to promote security assurances.

Tesco is not using cloud computing services. But they can subscribe for it so as to spend less on information technology system.

Conclusion.

From the above information, we have seen how important information systems are in the development of an organization as it is being applied at every managerial level in a business. So it is recommended that business owners should continue searching for more advance information systems that will help ease their supply and distribution chain.

Recommendations.

Information system is the only way for businesses to survive the pressure and competition that they are facing. If there is a any business that has not yet be highly connected to advance information systems, then that business should make a strategic plan about implementing cloud computing for a start because it is less expensive and will help the business save for future unforeseen circumstances.
