A computer is basically a machine which is able to perform operations automatically, by performing instructions given by the operator. Modern computers are able to do broad spectrum of activities such as mathematical operations, routing of data, analysis of data, graphics processing, text processing etc. These activities of a computer helps in achieving efficient utilization of available resources and less consumption of power.

The field of computer has witnessed numerous advancements over the past few decades. One of the developments which caught everyone’s attention was the development of computers which are manufactured on chip designs. This chip based personal computers are called as Tablet PC. The main advantage of using this device is that it is capable of performing many tasks that are common with a traditional PC. It is also capable of performing tasks that are not generally performed by personal computers.

Another significant development is the development of the ‘intelligent’ personal computing devices like the IBM ThinkPad. The latest models of these devices come with many advanced features which are found in desktop computers. They allow the user to perform various functions of the desktop computer in a more convenient way. The user is also able to adjust the settings of the ThinkPad in order to suit the individual needs. In this regard, it can be said that this type of computers are almost like a small mobile desk which is also capable of providing the advantages of a desktop computer.

Keyboards and mice are other important devices which are used for inputting data. A number of new generation personal computers are equipped with high performance solid state Drives (SSD). These drives use very high frequencies for storing large amounts of information. They are capable of operating at a higher rate of speed than the normal desktop computers. This enables the users to input the required data in a short time.

Apart from these, touch screen and pen input devices are also available in different types. Mouse is one such input device which is commonly found in the desktop computers. A mouse is used for inputting the text and images on the computer screen. On the other hand, a touch screen is generally a monitor which is used for providing visual input to the computer user. The best part about a touch screen is that it helps you to make use of different types of physical input devices without the need of using any external accessories.

All these and many more features have made the computer case a very essential part of a computer. The role of a computer case is mainly to protect the internal components of a computer such as the hard drive, CPU and the motherboard from getting damaged. Apart from this, it also allows you to store the different types of devices which are necessary for a computer. Therefore, it is advised to keep your computer case at a proper place which is safe from liquid and dust damage. Computer hardware is becoming more advanced day by day and now include more sophisticated computer related products which need utmost care and attention in order to work effectively and efficiently.
