The System Unit By: Cole and Mariah

What is the system unit? The system unit (also referred to as a tower or chassis) is the main part of a desktop computer. The system unit includes the motherboard, CPU, RAM as well as other components The term System Unit is often used to recognize a difference between the computer and other devices, such as the monitor, keyboard, and mouse. Motherboard: The core of the computer everything is connected to CPU (Central Processing Unit): The brain of the pc RAM (Random Access Memory): Holds all of the data the processor is using at a given time

Why is the system unit important? It is what you use to operate all system software It is what makes up your computer It allows access to anything on the computer You can’t type without a keyboard and can’t do anything without a mouse controller

Different types of System Software Operating system: Harnesses communication between hardware, system programs, and other applications. Device driver: Enables device communication with the OS and other programs Firmware: Enables device control and identification Translator: Translates high-level languages to low-level machine codes Utility: Ensures optimum functionality of devices and applications

Different types of System Software 2 Middleware- provides services to software Shells- user interface that helps get access to an operating system’s services Window systems-software the manages different parts of display seperately

What’s inside the system unit? A microprocessor Central Processing Unit (CPU) ^^^it carries out the instructions the user sends it A fan to cool all the components so it doesn’t over-heat and cause problems or potential disaster (fire) Optical drive Hard disk drive Connectors and expansion slots

What you need to know Memory cards save all the data from your computer (storage, search history) The power supply unit has two uses Convert electrical power available at a wall outlet so the circuits can run Delivers low voltages to each device due to their requirements

What is the function of a system unit? It protects all sensitive and easily damaged parts of a computer The case is large enough to store extra things such as: Second hard drive Larger memory card Higher quality video card It is however harder to open up the system unit of a laptop, because it is designed to keep the software safer

Any Questions???
