Computer Hardware
Your Name Goes Here
This report is about the computer hardware. The first part describes the computer
hardware components and the second part discusses how the information flows in the
computer.
Hyperlink the following two sections to their corresponding sections
Section I: Computer Hardware Components
Section II: Information Flow
Computer Hardware Components
CPU (Central Processing Unit)
The CPU is the primary component of hardware. It is the “Brain” of the computer system.
The CPU of a personal computer is the microprocessor.
The CPU measures the computer’s data processing speed. The measurement unit is MHz. For
example, 400 MHz, 500 MHz, …. The higher the number, the faster the computer.
Memory (ROM & RAM)
In order to process anything by CPU, the computer needs to remember what to do. That is what
the computer memory involves.
There are two kinds of computer memory: ROM (Read Only Memory) and RAM (Random
Access Memory).
Put the information below in a table (ROM, RAM, Input devices, Output and storage)
Memory
ROM
Permanent memory (information cannot be added or deleted)
Not very important to know the capacity when we buy the computer
RAM
Temporary memory (available while the computer is on)
Very important to know the capacity when we buy the computer
Input Devices
Input devices are used to enter data into the computer. Examples of input devices are keyboard,
mouse, joystick, graphic pad, touch screen, scanner, and voice recognizer.
Output Devices
Output devices are used to see the results of entered data. Examples of output devices are
monitors and printers.
Storage Devices
Storage devices are used to keep the work for future use. Examples of storage devices are hard
disks, floppy disks, ZIP disks, and writable CDs.

Keep in mind that you should have at least 2 related graphics somewhere within the
document. Your information should be included in the header somewhere. Also, the
‘back to the tops’ are typically located at the bottom of a page. Do not leave them in the
middle of the page.
