Hardware, software, data, people and process: As we learned in the first chapter, an information system of five components is composed. The physical parts of the device computing - ones that you can actually touch - are referred to as hardware. In this chapter we will take a look at this component of information systems, to learn a little about how it works, and around him to discuss some of the current trends. Technical Data  explained in it courses in Rawalpindi.

In this chapter we will examine digital devices, starting with the definition of what we mean by the term itself.

Digital Devices:

A digital device processes electronic signals representing either one ( "on") or a zero ( "off"). The ON state is represented by the presence of an electronic signal; the OFF state is represented by the absence of an electronic signal. Each one or zero is called a bit (a contraction of binary digit); a group of eight bits is a byte. The first PCs could process 8 bits of data at a time; can handle modern PCs now 64 bits of data at a time, which is where the term 64-bit processor comes.
