ARCHIVES

Abstract: A server is a computer used by multiple users for a specific application or multiple functions. The benefits of servers include centralized location, ability to control the air conditioning, consistent data archiving and speed. For example, a print server can eliminate the need for each user to have a personal printer. This would improve the efficiency of using network printer and reduce the cost of maintaining multiple printers. Application servers, while similar to file servers, are unique in that they run executable applications from the central location. By using application servers, costs of application software are reduced. Web Server performance is cardinal to effective and efficient Information communication. Performance measures include response time and service rate, memory usage, CPU utilization among others. A review of various studies indicates a close comparison among different web servers that included Apache, IIS, Nginx and Lighttpd among others. The results of various studiesindicates that response time, CPU utilization and memory usage varied with different web servers depending on the model used. However, it was found that Nginx out performed Apache on many metrics that included response time, CPU utilization and memory usage.
