Digital Forensics: Computer Peripherals and Hardware

A computer peripheral device can be defined as any device that is connected to the computer externally, which is not originally a part of the computer’s core architecture. The core architecture of the computer includes the motherboard, with power supply attached to it along with the Central Processing Unit (CPU) pre-installed; all of this contained together. Everything else can be said to be a peripheral device. However, there are several other elements that are required for a computer to actually function, they being the hard drive or the RAM i.e. the Random- Access Memory.
The term peripheral device is used to refer any external device other than the computer core. These external devices are used to connect to the computer and increase its functionality. The best example for this to explain is the use of Printer. Once it is connected to the computer, it can be used to print a number of documents.
