Read MoreEarliest data output time considering TACC in 8085 Microprocessor
27128 receives the Address A13-8 by 27128 from 8085AH by means of the octal line driver 74LS244, which has a propagation delay of 12 nS. Address ranging from A7-0 is received by 27128 from 8085AH by means of 74LS373 octal latch, which consists of a propagation delay of 30 nS. Thus, address ranging from A13-0 is received by 27128 at the end of 30 nS. So the data only comes out on D7-0 pins of 27128 by 30 nS + tAcc = 30 nS + 200 nS = 230 nS. Delays involved in accessing 27128 EPROM in ALS kit. Bus timing characteristics of MR machine cycle
Read MoreIn 8085 Microprocessor, compare I/O port chips and memory chips
Information is also stored in an Input Output port chip similar to a memory chip. Information of 1 byte are stored in an Input Output port chip on the other hand information of few bytes are stored in the Input Output port chips. An example to be cited as only 1 byte of information is stored in Intel 8212 I/O port chip, but 3 bytes of information are stored in Intel 8255 chip. Moreover, a large number of memory locations like 1K, 4K, 8K etc. are contained in the memory chips. We select memory chip location by the address pins ...

Read MoreWhat is TYPE_SCROLL_SENSITIVE ResultSet in JDBC?
This represents is a scrollable ResultSet i.e. the cursor moves in forward or backward directions. This type of ResultSet is sensitive to the changes that are made in the database i.e. the modifications done in the database are reflected in the ResultSet.Which means if we have established a connection with a database using a JDBC program and retrieved a ResultSet holding all the records in a table named SampleTable. Meanwhile, if we have added some more records to the table (after retrieving the ResultSet), these recent changes will be reflected in the ResultSet object we previously obtained.Following is an example ...
