All of our body’s systems work together. One body system often times cannot work without the help of another system. The best example of systems working together is the skeletal system and the muscular system. Muscles are attached to bones; the muscles make the bones move. Without bones there is nothing to hold together the structure of muscles. Without both of these systems working together our body would be impossible to move on its own. The skeletal system is the system in our body that provides

Examples of IPC Systems In this section‚ we explore three different IPC systems. We first cover the POSIX API for shared memory and then discuss message passing in the Mach operating system. We conclude with Windows‚ which interestingly uses shared memory as a mechanism for providing certain types of message passing. 3.5.1 An Example: POSIX Shared Memory Several IPC mechanisms are available for POSIX systems‚ including shared memory and message passing. Here‚ we explore the POSIX API for shared

Without this system our bodies wouldn’t have any source of motion or movement. From the skull all the way to the toes of our feet‚ everything is important. Out of the 206 bones‚ they all form our different shapes and make us all unique. They create our framework and enables us the move and perform our different

Respiratory system: The respiratory system is a combination of the Circulatory and Pulmonary systems feeding oxygen and nutrients to cells all around the body. These systems allow oxygen to enter the body‚ and be circulated around the body at a varying rate. These two systems work in conjunction with each other and have various rates of operation that are usually in as close a correlation as possible. Circulatory System: The circulatory system’s primary responsibility is to circulate oxygenated

Solar System About 4‚700 million years ago‚ the Solar System was just a spinning disc of dust and gas. The dust began to collect together and our Sun formed at the centre. Around Sun‚ lumps of rock joined up to form smaller bodies and‚ like the Sun‚ they heated up. But because they were smaller they soon cooled down and became planets. Sun accounts for 99.85 per cent of mass of the solar system. About 1.3 billion earths would fit inside the sun. The solar system consists of the Sun; the nine planets
