The Atmel AT89S52 is a microcontroller in the 80C51 family.
v stands for vaccum tube version
this mode is related to only port c.the bits of port c can be controlled directly by the microcontroller
Basically an electronic lock system consists of keypad for entering the password, an eeprom where the password can be saved in case of power failure, display unit may be optional, and an relay to activate or deactivate the lock check this link for basic blocks of password lock system http://www.dnatechindia.com/index.php/Kits/Microcontroller-Kits/Programmable-Electronic-Lock.html
Possibly Linear, in which case it means analog. The LM324 is an opamp.
An LM324 IC contains operational amplifiers. LM324 ICs can be used for different purposes in circuits, such as oscillators, rectifiers or oscillators as well.
That depends on the specific microcontroller.
The LM324 integrated quad operational amplifier has the characteristics of wide power supply voltage range and low static power consumption, so it is widely used in various circuits. This article describes the application circuits of different functions formed by LM324 in the regulation circuit of the DC speed regulation system: zero blockade circuit, given integrator circuit, adder and limiter circuit. By calculating and analyzing the working principle of these unit circuits, their roles in the system and the key point voltages, the core role of the LM324 integrated four-ops in the regulating circuit is explained.
LM stand for Liner Monolithic ic that is the National Instrunt perfix, I My right

The PIC is a specific architecture of microcontroller.
The voltage of the 8031 microcontroller is 2.7V to 5.5V.
The 8051 Microcontroller is a microcontroller ("chip") developed by Intel in 1980.
PIC Microcontroller which means Peripheral Interface Controller. PIC Microcontroller is originally developed by General Instrument's Microelectronics Division.
