Generations of Computers
The computers of today find their roots in the second half of the twentieth century. Later as time progressed, we saw many technological improvements in physics and electronics. This has eventually led to revolutionary developments in the hardware and software of computers. In other words, soon the computer started to evolve. Each such technological advancement marks a generation of computers.
Answer:
ring network
Explanation:
In a ring network, the nodes are arranged in a circular pattern where each node is connected to two adjacent nodes. In this topology, any node can communicate with any other node via the intermediaries.
In comparison,
- in a star network every communication needs to pass through a central hub node
- in a bus, each node is connected to a shared linear communication bus.
- in a hierarchical network nodes are organized along a tree structure layout.
The output of the formula will be TRUE because '83 = 83' is the only true expression of that three expressions present in the formula.
The output of the XOR function will be TRUE in case only one logical expression is true and FALSE otherwise.
