Description of a Technical Device

Before using any technical device, it is essential to have basic information about it. Background information about a technical device and its accompanying components is also important when purchasing it. A computer is a good example of technical device that a user or buyer needs to have background information about. The purpose of this paper is to give a description of the desktop Dell Inspiron, one of the recent computer products of the Dell Company.

Dell Inspiron description

A complete set of desktop Dell Inspiron computer comprises of four key components, namely, the CPU (the Central Processing Unit), keyboard, mouse and monitor (Tyler). The CPU is the main device that plays the role of processing information or data. The keyboard and the mouse are the movable components of the computer. Both play the role of data input. By pressing the labeled buttons of a keyboard, electronic signals are sent to the CPU, where they are processed to give specific information. The mouse has a right and a left button, which mainly play the role of controlling a cursor that is visible on the screen of the monitor. The monitor plays the role of output; it displays the information that is processed by the CPU (Tyler).

All the four components of the computer are black in color. The exterior parts of the four components are mainly made of plastic, except the CPU that has a back that is made of metal. The front side of the monitor is made of silver plastic. The CPU is around eighteen inches in height, twenty inches in length and six inches in width. The keyboard is about six inches in width and twenty inches in length (Dell). The monitor has a screen of about seventeen inches in height and twenty-one inches in length, although its size may vary. From the front, the CPU has a CD or a DVD drive that is easily opened through pressing a button. The CPU also has USB ports at the front and at the back. A USB port is small opening that allows the user of a technical device to plug external devices such as external hard drives, flash drives, iPads and iPods. Also, the CPU has a port for a camera memory, which has a different size from the other ports. The port allows the user to plug memory card of a camera. In addition, the CPU has ports for the keyboard, monitor, speakers and printers (Dell). As well, the CPU has an Ethernet port that allows the user to connect the computer to network.

The CPU has several important internal components, which have an influence on its functioning ability. Among the most important internal components of the computer are the processor, memory (RAM), storage (hard drive), optical drive, video graphics, media card and operating system. There are several varieties of a Dell Inspiron computer, and the sizes of the internal parts depend on the type (Dell). The details of the internal parts are often written on them and are also visible after switching on the computer, in the hardware settings. Among other functions, the device can be used in accessing internet, researching, playing games, storing data, typing documents, listening to music, drawing pictures, telecommunication, calculating and storing numerical data, word processing and watching news (Dell). The device can be used at home and in organizations.

Conclusion

The Dell Inspiron computer has many important parts. Understanding both the internal and external components of the computer is important. Although a user or a buyer may not have knowledge of the technical information about the device, the basic information is important when making purchasing decisions and in understanding its applicability.
