A system that I use on daily basis is my home computer. My processor is a core i7 with 4GB RAM. My internal memory is 1 terabyte and runs on windows 8, the latest Microsoft operating system. The main components of my computer include: power supply, motherboard, the hard disk drives, monitor, keyboard, and mouse. The power supply serves the purpose of supplying power to the system. Without a power-backup, a computer cannot function. A motherboard hosts the key components of the computer. The components of a motherboard include a microprocessor which is the brain of the computer. A microprocessor performs commands and controls the entire operations of a computer. A motherboard also holds the RAM. Ram functions as the memory that is powered to retain the content of the system. The hard disk drives of my computer are where my files are stored permanently (Hwang et al, 1993). Additionally, this is where my operating system is installed.
The monitor of the computer acts like a television set letting users view how the commands respond. Monitors vary with sizes and are measured with inches. The keyboard of the computer is where a user enters texts commands into the system. Lastly, the mouse is a point and click interface used to enter commands into the system. Laptops can operate well without a mouse. Moreover, my computer has installed software stored in digital form within the memory of a computer. My computer has a system software, utility software, and application software. The system software is used to control and manage hardware components in a computer. The utility software in my computer includes anti-virus, disk-defragmenters, among others. The application software in my computer includes Microsoft office, games, and browsers among others (Shaw & Garlan, 1996). The above components when connected interact to ensure that the computer functions in a right manner. Without any of the components above, a computer will function well. Thus, the components are interdependent on each other. The external factors that affect the running of a computer include power, and sometimes the weather. In many occasions, rainy weather affects the signal of the internet.
When selecting a computer equipment, it is important to consider the relationship between a system, the environment, its boundaries, and interface. A system is defined as a collection of components that are connected together and structured in a particular way to be recognized as a single unit. An example of a system is the computer. The system selected forms the basis of a boundary, set by the limitations formed by the internal components of a system (Reilly, 2001). The environment is basically the physical setting in which a system is positioned. For instance, the manner in which an environment affects the operation of the system is when a computer is placed a distance from WIFI connectivity, thus affecting internet connectivity. If however, a computer is placed within the radius of a strong WIFI, then connection will occur. The interface is the process in which a computer user relates with the system. The easiness and hardness of user to use a system effectively and be able to maneuver through the system depends on the type of the interface used in the system.
