What Software is
A set of instructions that tells a computer how to execute functions and tasks. Software code is written in a programming language that makes computer systems and hardware work. Some programs contain millions of lines of code, and there are millions of software programs. The two basic software categories are system software (which makes your computer run properly, behind-the-screens) and application software (which include the programs, such as Microsoft Word, that you use while working on the computer).
The meaning of Server farm
A group of networked servers that are housed in one location in order to streamline internal processes, distributing the workload between the individual components. In other words, a server farm expedites computing processes by harnessing the power of multiple servers. The farms rely on load-balancing software that tracks demand for processing power from different machines, prioritizes the tasks, and schedules and reschedules them depending on the priority and demand that users put on the network. When one server in the farm fails, another can step in as a backup.
Combining servers and processing power into a single entity has been relatively common for many years in research and academic institutions. Today, more and more companies are utilizing server farms to handle the enormous amount of computerized tasks and services they require.
