Introduction

Space on a device screen is always limited, but sometimes you come across a situation in which you want to display lots of information or services on the screen. In such a situation, you can either use dockable widgets that can be floated anywhere on the screen; MDI to display multiple documents as and when desired; a Tab Widget box to display information in different chunks; or menus to display the required information on the click of a menu item. Also, to better understand networking concepts, you need to understand how clients and servers communicate. This chapter will help you understand all this.
