Answer:
The Dewey Decimal Classification (DDC) is structured around ten main classes covering the entire world of knowledge; each main class is further structured into ten hierarchical divisions, each having ten sections of increasing specificity.[1] As a system of library classification the DDC is "arranged by discipline, not subject", so a topic like clothing is classed based on its disciplinary treatment (psychological influence of clothing at 155.95, customs associated with clothing at 391, and fashion design of clothing at 746.92) within the conceptual framework.[2] The list below presents the ten main classes, hundred divisions, and thousand sections.[3]

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.
Answer:
Memory-mapped I/O and port-mapped I/O are two complementary methods of performing input/output between the central processing unit and peripheral devices in a computer. An alternative approach is using dedicated I/O processors, commonly known as channels on mainframe computers, which execute their own instructions.
