A computer is made up of physical, mechanical, magnetic, electronic and electrical components and the multiple accessory devices that can be added are termed as Hardware. This includes equipment that was connected to the computer at the time of assemble, as well as peripheral equipment that are added later. It includes any device that is connected to the computer and is controlled by the computer's microprocessor.

Information about hardware and devices is also available in System. Details about PC Hardware can be easily accessed in Device Manager of a personal computer. All the PC Hardware devices are listed on the device manager installed of the computer. The device manager, in a computer, can be used to change the properties of any device. Each device is listed under the hardware to which it is connected. The hardware devices, which are installed in the computer and are connected, are grouped as type of resources- Direct Memory Access (DMA), Input/output (I/O), Interrupt Request (IRQ) and Memory. The Hardware in the device manager can been as how they are connected to the computer. PC Hardware profiles provide a way to set up and store different hardware configurations.

The Add Hardware Wizard can be used to install, uninstall, or configure certain types of hardware. Hardware Profiles suggest which driver to load when the available PC Hardware changes. PC hardware requires resources to properly operate with the computer and the software installed in the computer. Hardware compatibility tests implement the combination of a device, a software driver, and an operating system under controlled conditions to verify that all components operate properly.

Disk Defragmenter is a tool which explores local volumes and merges fragmented files and folders. A computer runs better with regular disk defragmentation. Defragging the hard drive organizes the hard drive so that access to files and programs is more efficient. Other PC tools like Event Viewer, Shared Folders, Local Users and Groups, Performance Logs and Alerts, and Device Manager also help in managing the PC system performance.

The performance options which control the memory used by programs, including paging file size, or environment variables, can be changed by the user logged on as Administrator. Startup and recovery options show the operating system used by the computer, when it starts and which actions it performs in case of improper shutdown.

The network and logon information, such as the computer name, workgroup or DNS domain name can be viewed using System. A user can see and access the details about user domain or workgroup membership, or start the Network Identification Wizard and connect to a network. A user profile encloses the personal settings associated with the user's logon configuration.

PC Hardware needs to get regular support to work properly and efficiently. Today, PC Hardware maintenance has become more cost effective and with coming up of remote PC Support services, it has become more convenient and cogitative, since these services are free policies. Customers do not have to pay if the issue is not resolved.
