1. 392 decimal ko binary main convert karna tha.
2. ak na mukamal diagram thi us ko mukamal karna tha.
3. difference b/w ROM and PROM.
4. Two use of PROM
5. ak amplifir main sy tha shiad. wo yad ni.
6. agr 4 bit k shift reg main jo k serial to parallel hai aur initially clear hai is main 4 clock puls pr kea status ho ga.
7. aur mcq's easy hi thy mery to past paper main sy 5 to 10 percnet hi ay jo past paper ki file mary pas thi but easy thy.
best of luck.
3. difference b/w ROM and PROM.
ReplyDeleteAns:
• A ROM contains permanent data that can not be changed. Thus ROM memory does
not allow write operation. A ROM stores data that are used repeatedly in system applications,
such as tables, conversions, programmed instructions for system initialization and operation.
ROMs retain data when the power is turned off.
• PROM: Programmable ROM allows storage of data by the user using a PROM
programmer. The PROM once programmed stores the data permanently.
4. Two use of PROM
DeleteOnce the PROM is programmed its contents can not be erased and programmed again. PROM uses a fusible link to connect the output of the MOS transistors to the column line. The row lines are permanently connected the gates of the transistors. When the fuse is intact, logic high is seen on the column line when the corresponding cell is selected. When the fuse is blown the column line outputs a logic low.
