1. Module 1: Concepts of information Technology

2.  Central processing unit (CPU)  Hard disk  Common input and output devices  Types of memory Main Parts of a personal computer

3. The CPU (central processing unit) is the part of a computer controls the interpretation and execution of instructions. Definition of CPU Intel® Pentium® Processor E6300 (2M Cache, 2.80 GHz, 1066 MHz FSB)

4.  CPU stands for Central Processing Unit.  Its job is to process the instructions contained within computer programs. What Does CPU Stand for Feature : CPU chips are generally very small and very thin Type: The primary manufacturers of CPUs for personal computers are Intel and Advanced Micro Devices (AMD). Advanced Micro Devices Function : A microprocessor chip is a small piece of silicon containing thousands

5.  In a personal computer, a hard disk drive (HDD) is the mechanism.  controls the positioning, reading, and writing of the hard disk  There are 2 types of hard disk. Definition of Hard disk HDD : Samsung 320GB SATA2 7200RPM 16M

6. Hard disk drive A hard drive is made up of 2 to 5 magnetic disks, each measuring at around 2.5 inches in diameter. It also has a motor, spindles, heads, controllers and an actuator. All the components are encased in metal. This hard drive is located in computer, so we can’t bring to outside, but it is safe. One of the advantages is that this type of hard drive contains many GB, such as 1 TB.

7. Portable Hard Disk A hard drive is made up of 2 to 5 magnetic disks, each measuring at around 2.5 inches in diameter. It also has a motor, spindles, heads, controllers and an actuator. All the components are encased in metal. There are many types of portable hard disks, which are 120GB, 160GB, 320 GB, 500 GB, and etc. Portable Hard Disk’s advantages are that we can carry it easily, and it contains lots of GB. However, they are easy to broken.
