components of system unit  SYSTEM UNIT/CASE A computer case, also known as a computer chassis, its main functions are to protect the computer from external influences and mechanical damage and maintain an optimal temperature regime inside. Typically the system unit is made of aluminum, steel, or plastic.  CENTRAL PROCESSING UNIT (CPU) It is the brain and the heart of the system. This is also known as processor or microprocessor. It performs calculations. does comparisons, and controls the other parts of the computer system.  DVD ROM DRIVE It is read only digital versatile disc (DVD) usually used to store large software application. DVD ROM can be recordable and rewritable boat recordable dvd supporting dual layer technology are backward compatible with some hardware developed before the recordable medium.  Sharing data and files ADVANTAGES OF DVD ROM Restore/back-up DRIVE Affordable cost per gigabytes  Rewriting DISADVANTAGES Compatibility issue OF DVD ROM Resistless DRIVE Expensive SSD VS HDD  SSD HDD SSDs store data in HDDs store data in Both are flash memory. magnetic disks. used to Faster, quieter, store data Cheaper, and smaller, more offer more durable and capacity and HDD and consume less easier data SSD are energy. recovery if used to Best for storing boot the damaged. operating system, system Best for storing gaming apps, and extra data such as frequently used movies photos and file. documents.  POWER SUPPLY The power supply fuels the entire computer system by providing electricity. Usually located at the CPU or PC tower’s back, the power cord plugs directly into the electricity socket.  RAM ➤ It is the memory which stores data until the machine is working. ➤ It allows stored data to be accessed randomly. ➤ Its main function is to store the data temporarily.  MOTHERBOARD A motherboard is one of the most essential parts of a computer system. It holds together many of the crucial components of a computer, including the central processing unit (CPU), memory and connectors for input and output devices.  EXPANSION CARD An expansion card, also known as an expansion board or add-on card, is a hardware component that you can insert into a computer's expansion slot to enhance its functionality.  FLOPPY DISK DRIVE A floppy disk is also referred to simply as a floppy. Since the early days of personal computing, floppy disks were widely used to distribute software, transfer files, and create back-up copies of data. SHORT ACTIVITY instructions You will be shown several pictures of components of system unit.
