Storage devices and media


What are Storage devices?
Storage Devices are the data storage devices that are used in the computers to store the data.
The computer has many types of data storage devices. Some of them can be classified as the removable data Storage Devices and the others as the non removable data Storage Devices.
The memory is of two types; one is the primary memory and the other one is the secondary memory.

The primary memory is the volatile memory and the secondary memory is the non volatile memory. The volatile memory is the kind of the memory that is erasable and the non volatile memory is the one where in the contents cannot be erased. Basically when we talk about the data storage devices it is generally assumed to be the secondary memory.

The secondary memory is used to store the data permanently in the computer. The secondary storage devices are usually as follows: hard disk drives – this is the most common type of storage device that is used in almost all the computer systems. The other ones include the floppy disk drives, the CD ROM, and the DVD ROM. The flash memory, the USB data card etc.

What is Cyber Crime


It is a criminal activity committed on the internet. This is a broad term that describes everything from electronic cracking to denial of service attacks that cause electronic commerce sites to lose money".

Cybercrimes can be basically divided into 3 major categories:

1. Cybercrimes against persons: Cybercrimes committed against persons include various crimes like transmission of child-pornography, harassment of any one with the use of a computer such as e-mail.

2. Cybercrimes against property: These crimes include computer vandalism (destruction of others' property), transmission of harmful programmes.

3. Cybercrimes against government: Cyberterrorism is one distinct kind of crime in this category. The growth of internet has shown that the medium of Cyberspace is being used by individuals and groups to threaten the international governments as also to terrorise the citizens of a country. This crime manifests itself into terrorism when an individual "cracks" into a government or military maintained website.

Whole new world of cybercrime


Online theft costs $1 trillion a year, the number of attacks is rising sharply and too many people do not know how to protect themselves.

There are a wide range of threats facing the internet.

To start with is the 'traditional cybercrime': committing fraud or theft by stealing somebody's identity, their credit card details and other data, or tricking them into paying for services or goods that do not exist. The majority of these crimes, one participant said, were not being committed by a youngster sitting in a basement at their computer. Rather, they were executed by very large and very well-organised criminal gangs.

Another threat is the 'flaws' in the set-up of the web itself.
It is organised around the principle of trust, which can have unexpected knock-on effects.

Yet another threat is the overdependence on Web which can lead to 'cyber warfare'.

Two years ago, a political dispute between Russia and Estonia escalated when the small Baltic country came under a sustained denial-of-service attack which disabled the country's banking industry and its utilities like the electricity network. This was repeated last year, when Georgia's web infrastructure was brought down on its knees during its conflict with Russia.

Just give it a thought!! Do we need a new approach to handle cybercrimes?
