1.Ports - Ports are connecting points by which devices are connected to a system. There are 2 Types of Ports .

a)- Standard Ports- There are 4 categories ,DVI ,USB ,VGA , Ethernet . ex- USB- It is used to connect various devices like

mouse , keyboard etc.

b)- Specialized Ports - There are  5  categories under this HDMI-High Definition Multimedia Interface,eSATA , MIDI , mDP and Thunderbolt. ex- Thunderbolt -It is specialized for Apple and is same as mini display port.

2,) Power Supply is responsible for the power supplied to the computer due to which they become able to work on.

AC adapters converts the AC current to DC current as the computer needs DC current to work .

3)Computer gets the data and information in the form of analog signals and this has to be converted into digital signals to be

understood by the computer . And both these type i.e analog and digital signal are known as electronic data and instructions.

4)- The Computer Memory is used to store data and instructions . There are three types -

1)RAM - Random Access Memory - It is used to store the data which is of immediate use , or are currently running, If the

power is lost then its data is also lost.

2)- ROM- Read Only Memory- It can store the data even if the power is lost . It can only receive and read the data but can't

write.

3)- Flash Memory-Like the ROM , It can also retain the data and information even if the power is lost. It is non volatile

in nature . The data on it can erased and rewritten.
