What do you mean when you say that Java has two concepts?
You are talking about the implementation point view of Abstract class and the interface. Let's go. 1. Interface helps Multiple inheritance:- In java you can't have a class inherited from more than one class, i.e. the multiple inheritance. Interface helps us in implementing the multiple inheritance(virtually), because their is no such restriction in implementing more than one interface. But the Abstract class can't help you doing so. 2. Interface helps global declaration:- In C/C++, a header file holds the declaration of the functions and the symbolic constants. Similarly we can have a interface which is having only the symbolic constants which is same for all classes which implements it. And also the method have only the signature and the class which implements it is free to write the body at his own wish. Abstract class can't help in doing this. 3. Abstract class is more secure:- Because in Interface we have all the things public. But in Abstract class we can have private and also friendly members. 4. Interface is overhead:- Because in Interface we are bound to implement all the methods though some of them we actually need. But in case of the Abstract class we can override the methods which we want.
Why is study of trigonometry important in optics?
The sine ratio plays an important part in the refraction of light at the interface of two media through which the light travels - such as the interface between air and the glass of a lens.
What does UI mean?
It means User Interface.. I was wandering myself until recenty.. I hope i helped and if i did im glad
What is a 3.5 inch SATA?
3.5 inch refers to the width of the drive. SATA (serial ATA) is the drive interface.
What is the function of RS232?
'RS-232' (Recommended Standard 232) is a Standard American format for serial data transmission by cable, such as from computer terminal to modem. RS-232 transmission utilizes a distinctive 25-pin connector, but under most circumstances only a few of the 25 conductors are used. RS-232 was adopted as a standard for serial binary data signals connecting between a DTE (Data terminal equipment) and a DCE (Data Circuit-terminating Equipment). It is commonly used in computer serial ports. RS-232 is similar to the ITU-T standard 'V.24'. The International Telecommunications Union (ITU), which is closely associated with the United Nations (UN), issues various standards for telecommunication systems and equipment for use in all countries which support the UN and ITU.
What are the advantages and disadvantages of RS232 interface?
This interface is easy to use and to learn. Some disadvantages would be that it does not have all of the features that you may want.
What do you use in laptop - rs232 or rs485?
rs232
What are the Differences between RS232 and RS449?
rs232 isfaster than rs449
Make USB to RS232 converter?
Yes, you can get a USB to RS232 converter (aka USB to Serial).
What is the difference between rs232 and rs485 port?
Difference between Rs232 and RS485 is Only Distance RS232 is not for long or far distance .. but RS485 can be use for LONGEST distance ..RS232 is single ended communication where as RS485 is Differential communication.Max.no of receivers in RS232 is only ONE, whereas in RS485 is 32.Max.no of transmitters in RS232 is only ONE whereas in RS485 is 32.IN RS232 there is no pin to change from transmitter mode receiver mode. But, In RS485 have DE pin to set transmitter mode and RI to set receiver mode.
Where can one purchase RS232 cable?
One can purchase a RS232 cable at most electronic stores. A few common examples of stores that have RS232 cables for sale are Best Buy, Radio Shack, and Fry's.
Full form of RS in RS232?
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
What are RS 232C control and service discrete IR codes?
Through RS232 interface one can connect to service menu and diagnose/configure the device, same applies to service IR codes. I have come across this in televisions.
Is rs232 synchronous or asynchronous?
It can be either.
What is 232 in RS232 and MAX232?
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
Why the name RS232?
Because R2D2 was already taken!
Why ttl voltage level converting to rs232 level?
Whwn an IC is connected to a PC, then the voltage levels of these two should be synchronized. For this purpose, the TTL voltage level is converted to RS 232 level. RS 232 is the interface between a PC and an IC.
