A team of British scientists have reportedly discovered a way to build communications networks using quantum cryptography and impenetrable codes, crucial for sensitive electronic data transfer.
With increased threat to sensitive electronic data being vulnerable to attacks, the impenetrable...
Moore’s law states that the level of technology and computing power should double every two years, and so far the postulate hasn’t been wrong in more than 50 years. A group of IBM scientists have now managed to develop a data storage technique which allows for information to be stored with as...
Magnetoresistive Random-Access Memory is a non-volatile computer memory (NVRAM) technology that has been under development since the 1990s. Continued increases in density of existing memory technologies – notably flash RAM and DRAM – kept it in a niche role in the market, but its proponents...
Radio Frequency Identification (RFID) uses "tags" to identify objects. Tags can operate passively, without an on-board source of power allowing them to be paper-thin and smaller than a penny. Tags can be active, with a battery power supply, allowing them to operate at longer ranges. Merchandise...
I am working on my final year project "RFID based Access System"..
Here's the code to interface the LCD with 89C51..
#define cmdpt P3
#define datapt P2
#define q 100
sbit rs = cmdpt^0; //register select pin
sbit rw = cmdpt^1; // read write pin
sbit e = cmdpt^6; //enable pin...
