Test: Categories Of Computers - Question 1

### Digital data refers to information that is:

Detailed Solution for Test: Categories Of Computers - Question 1

Digital data refers to information that is discrete

Test: Categories Of Computers - Question 2

### The computer that process both analog and digital is called:

Detailed Solution for Test: Categories Of Computers - Question 2
The computer that processes both analog and digital is called a Hybrid Computer.

1. Analog Computer: An analog computer is a type of computer that processes continuous data and performs mathematical calculations using physical quantities such as voltage, current, and resistance. It is suitable for solving complex mathematical equations and simulating real-world systems.

2. Digital Computer: A digital computer, on the other hand, operates on discrete data and performs calculations using binary digits (0s and 1s). It is commonly used for general-purpose computing tasks, data processing, and executing software instructions.

3. Hybrid Computer: A hybrid computer combines the features of both analog and digital computers. It can process both continuous analog signals and discrete digital data. This type of computer is often used in scientific and engineering applications where real-time data acquisition and control are required. For example, in weather forecasting, a hybrid computer can process analog weather sensor data and perform digital calculations to predict future weather patterns.

Summary:
A hybrid computer is capable of processing both analog and digital data, making it suitable for applications that require real-time data acquisition and control.

Test: Categories Of Computers - Question 3

### The two basic types of signals are analog and ______.

Test: Categories Of Computers - Question 4

Which of the following characterizes an analog quantity?

Test: Categories Of Computers - Question 5

Which one of the following is a digital type of computer?

Test: Categories Of Computers - Question 6

Which type of signal is represented by discrete values?

Detailed Solution for Test: Categories Of Computers - Question 6
Type of Signal Represented by Discrete Values - Digital Signal
Digital signals are represented by discrete values, which means they have distinct and separate levels or states. Here is a detailed explanation:
1. Analog Signal:
- Analog signals are continuous in nature and can take on any value within a range.
- They are represented by a continuous waveform that varies smoothly over time.
- Examples of analog signals include a voice signal, temperature measurements, and voltage variations.
2. Digital Signal:
- Digital signals are discrete in nature and can only take on specific values.
- They are represented by a series of binary digits (0s and 1s).
- Each digit, known as a bit, represents a specific level or state of the signal.
- Examples of digital signals include computer data, digital audio, and video signals.
3. Noisy Signal:
- A noisy signal refers to a signal that is corrupted by unwanted random variations or disturbances.
- Noise can be introduced during signal transmission, reception, or due to external interference.
- Both analog and digital signals can be affected by noise, but it does not define the type of signal.
4. Both [a] and [b]:
- This option is incorrect because only digital signals are represented by discrete values, not analog signals.
- Analog signals are represented by continuous values.
5. None of these:
- This option is also incorrect as digital signals are indeed represented by discrete values.
Therefore, the correct answer is Option B: Digital.
Test: Categories Of Computers - Question 7

In which one of the following fields hybrid computers are used?

Test: Categories Of Computers - Question 8

Analog signals have ______ values.

Test: Categories Of Computers - Question 9

Which of the following is an example for digital signals?

Detailed Solution for Test: Categories Of Computers - Question 9
Digital signals are representations of information in the form of discrete values, typically represented by binary digits (bits). Examples of digital signals include:
A. Voice:
- Voice signals are typically analog signals, as they are continuous and can take on any value within a range. However, they can be converted into digital signals through a process called digitization, where the voice signal is sampled at regular intervals and each sample is quantized into a binary value. Therefore, voice signals can also be considered as digital signals once they are converted.
B. Temperature:
- Temperature is a continuous and analog quantity, as it can take on any value within a range. Therefore, it is not an example of a digital signal.
C. Binary bits:
- Binary bits are the fundamental units of digital signals. They can have two possible values: 0 or 1. Digital systems use binary bits to represent and process information.
D. Pressure:
- Pressure is a continuous and analog quantity, as it can take on any value within a range. Therefore, it is not an example of a digital signal.
E. None of these:
- This option is incorrect, as binary bits are indeed an example of digital signals.
In conclusion, the correct answer is C. Binary bits, as they are the fundamental units of digital signals.
