Answer: there is an overflow
Explanation:
Here using 4-bit signed fields to store the addition value.
0111 + 0101 = 1100
In above addition the MSB is reserved for sign.
If MSB is 0 means the number is positive.
If MSB is 1 means the number is negative.
The first number 0111 has MSB 0 means it is a positive number.
The second number 0101 has MSB 0 means it is also a positive number.
But after addition the result obtained is 1100 which MSB is 1 indicating the
result is negative number.
How can it be possible to add two positive numbers and get a negative number as result.
This type of situation is called overflow situation.
It is used for error detection purpose.
therefore there is an overflow
Data visualization
Data visualization is a good starting point for data mining. There are several approaches to data mining that supports smart decisions. Data visualization places data in a visual context. It extracts the data in a clear and understandable way without any form of reading or writing. Results are displayed in the form of pie charts, graphs, and any other statistical representation. Such multidimensional views of data aid in developing a preliminary understanding of the trends that are hidden in the data set.

Answer:
There are two basic operational modes of 8255:
Bit Set/Reset mode (BSR mode).
Input/Output mode (I/O mode).
Features of 8255 Microprocessor:
Mode 0 : Simple Input/Output.
Mode 1 : Input/Output with handshake.
Mode 2 : Bi-directional I/O data transfer.
It has three 8-bit ports : Port A, Port B, and Port C, which are arranged in two groups of 12 pins.
The 8255 can operate in 3 I/O modes : (i) Mode 0, (ii) Mode 1, & (iii) Mode 2.
