The document discusses hardware and software components of a computer system. It describes the four main hardware components as the CPU, memory, input devices, and output devices. It then explains the two main types of software: application software which performs specific tasks, and system software like operating systems and compilers that support the execution of other programs. Finally, it provides some common examples of application software like Microsoft Word, PowerPoint, web browsers, and multimedia programs.

2. Hardware
• Four components of a computer system:
• CPU - central processing unit
• Makes decisions, performs computations,
delegates input/output requests
• Memory: Disk Drives, CD drives, Tape drives, USB
flash drives.
• Stores information
• Input devices: Keyboard, Mouse,
• Gets information from the user to the

• Application software
• Easy-to-use programs designed to perform
specific tasks
• System software
• Programs that support the execution and
development of other programs
• Two major types
• Operating systems
• Translation systems (compilers & linkers)
