Answer:
A waveform that switches representing the two states of a Boolean value (0 and 1, or low and high, or false and true) is referred to as a digital signal or logic signal or binary signal when it is interpreted in terms of only two possible digits.
<u>Explanation</u>:
The establishment of the Abacus brought about one of the first counting device (calculator). This device was a mechanized computer that supported numeric calculations. However<u>, the process was entirely manual and mechanized. </u>This innovation led to;
First-generation of computers, although not entirely manually operated like Abacus, made use of vacuum tubes, were very big in size and could store only a small amount of information.
Second Generation of computers
unlike the first generation that uses vacuum tubes, this one came with new technology; the use of transistors. The computers were smaller in size than vacuum tubes.
Third Generation computers made use of IC (Integrated circuits) for the first time. Contained higher storage capacity and was more reliable than previous generations.
Fourth Generation computers became known as the personal computer generation. This generation brought the use of personal computers on a personal level as they use microprocessors, was easy to carry about, had larger storage capacity and faster speed of operations.
Fifth-generation of computers is known as the age of artificial intelligence. These computers were programmed with the ability to make decisions just like a human being would.
Answer:
An Oracle sequence uses the identity column property to automatically number rows.
Explanation:
An Oracle sequence is a tool that can be used to generate a number sequence. Oracle has the capacity to help you create an auto-number field by using one of its tools called sequence.
A sequence is an object in Oracle that is used to generate a number sequence for input to a table. This is required when you need to generate primary key values by the use of identity columns.
So, Oracle sequence can automatically number rows by the use of identity columns.
