A Correct answer
Explanation

At pushdown automata is deterministic if there is at most one transition applicable to each configuration.

In automata theory, a deterministic pushdown automaton (DPDA or DPA) is a variation of the push down automata. The class of deterministic pushdown automata accepts the deterministic context free languages, a proper subset of context free languages.

 A deterministic pushdown automaton has at most one legal transition for the same combination of input symbol, state, and top stack symbol. 

A pushdown automaton (PDA) is a finite state machine which has an additional stack storage. The transitions a machine makes are based not only on the input and current state, but also on the stack.

The main electronic component used in first generation computers was _________________.

  1. Transistors

  2. Vacuum Tubes and Valves

  3. Integrated Circuits

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The main electronic component used in first generation computers was Vacuum Tubes and Valves.

Vacuum Tubes (1940-1956) The first computer systems used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. Transistors were used for second generation computers and integrated circuits in third generation. First generation computers used vacuum tubes and valves as their main electronic component. Vacuum Tubes were invented by Lee DeForest in 1908.

The first generation computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. • The vacuum tube was developed by Lee De Forest. A vacuum tube is a device generally used to amplify a signal by controlling the movement of electrons in an evacuated space.
