How many address lines and data lines are required for a 128k x 8 memory system?

17 address lines and 8 data lines. 2^17=128k


How many address lines and data lines are required from 256K 16 memory system?

In a 256K x 16 memory system, the memory has 256K (256 * 1024 = 262,144) addressable locations and each location holds 16 bits of data. To calculate the number of address lines needed, we find the base-2 logarithm of 256K, which is 18 (since 2^18 = 262,144). For the data lines, since each location holds 16 bits, 16 data lines are required. Thus, the system requires 18 address lines and 16 data lines.

What is the function of dptr?

The dptr (data pointer) is a register used in microcontroller architectures, particularly in the 8051 family, to point to data in memory. It facilitates access to data stored in external RAM or in the data memory space, allowing for efficient data manipulation and retrieval. By using dptr, programs can handle larger data sets and perform operations on data located beyond the internal memory limits.


Why Do Broken Line Graphs Have Dotted Lines?

Broken line graphs use dotted lines to indicate that the data points are not continuous or that there are gaps in the data. The dotted lines visually differentiate segments where values are missing or where the relationship is not established, helping to prevent misinterpretation of the data trends. This style enhances clarity by signaling to viewers that the information is incomplete or that the data points represent distinct intervals.
