Define Systems and Storage Management, Electronic Mail and The Internet and Intranets

Systems and Storage Management

Systems management includes a variety of functions for managing computers in a networked environment, including software distribution, version control, backup &

recovery, printer spooling, job scheduling, virus protection and performance and capacity planning. Network management may also fall under the systems management umbrella.

Storage management has become critical for two reasons. First, there is an ever- increasing demand for storage due to the Internet, document management and data warehousing as well as increasing daily transaction volume in growing companies. Secondly, finding the time window in a 7x24 operation to copy huge databases for backup, archiving and disaster recovery has become more difficult.

Electronic Mail

Most earlier proprietary mail systems have given way to Internet protocol-based e-mail; however, some still remain within the enterprise. No matter which mail system is used, keeping the network safe from virus-laden attachments and preventing it from overloading because of spam is an ongoing challenge.

The Internet and Intranets

As if everything above is not enough to keep the technical staff busy, the World Wide Web came along in the mid-1990s with the force of a tornado, and nothing in the IT world would ever be the same.

Today, the Internet sets many of the standards, and the browser has become an interface for accessing just about everything. Every component of system software from operating system to database management system, as well as every application on the market, was revamped in some manner to be Internet compliant. Today, almost every new application deals with the Internet in some manner.

In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software.
