No other innovation has resulted in the creation of such a marvel as computers. From normal routine activities to the more complex tasks, the job undertaken by the computers are numerous. The size of the computers, the operations performed by it and the processing power of the computer hard drive has brought about classification of computers into different groups.
This article aims to highlight some of the major classifications of the computers.
1. Personal Computer
Typically used in home and offices, the personal computers can take the form of desktops, laptops and palmtops. Formerly known as the microcomputers, the PCs generally adopt Windows operating system to perform the operations. Usual applications like the mailing, games and other simple operations are performed by the system that can be connected to the LAN using a cable or the wireless.
Desktop computers
It comes with large vertical cases that store the main processor inside or as a small form factor model that has the Central Processor lodged behind the LCD monitor. Mac is a typical example of a small form factor model. Besides being stationary, these computers have powerful processors, larger memory and enjoy lesser costs.
Tablet computers
These mobile computers have a touch screen that performs operations on the basis of the command given through the stylus or finger tapping on the screen. Tablet computers like the PDA adopt flash memory in place of computer hard drive for mass storage.
Laptop computers
Laptop is a computer that has the processor, memory, keyboard, computer hard drive and the display integrated into a single unit that can operate on battery. The light-weight laptops, Wi-Fi laptops, dual core laptops and the power laptops are some of the models available under this category.
2. Work station
Workstations come with powerful processor, high-resolution screen, supplementary memory capacity and other characteristics that assist the system in the performance of tasks that require larger computing capabilities. Except for the diskless work station, the other categories come with a hard disk.
3. Servers
Servers are computers that have powerful processors, huge computer hard drives and enhanced memory that works to offer services to other systems through a network. Some of the typical examples of server applications are the web servers, file server and the e-mail servers.
4. Mainframe computers
In earlier times, the term mainframe computers was used to denote the large models of computers that took immense space as big as an entire room by its mere presence. The modern day mainframes are, on the other hand, the enormous and costly machines that are competent to offer support to the changing needs of thousands of users simultaneously.
5. Super computers
Supercomputers are the highly efficient and powerful machines that can manipulate thousands of calculations, making it highly suited for specialized jobs like scientific simulations, nuclear energy design, fluid dynamic calculations and similar activities.
6. Wearable computers
The incorporation of the small computing devices into the watches, fabric and the cell phones have resulted in their multiple applications in health monitoring, behavioral studies, military operations, etc. that requires the scrutinizing of the user? physical movements. The development made by the wearable computers has today taken us to a world with immense potential for development.
