Communication Waves

Front

Analog Information Noun

---

[an-uh-log in-fer-mey-shuhn]

Back

Analog Information

---

Information represented by a smooth and continuous signal, such as the data found in traditional audio recordings or film.

---

Example: Sound waves are shown as continuous signals, illustrating how analog information is represented.

Front

Digital Information Noun

---

[dij-i-tl in-fer-mey-shuhn]

Back

Digital Information

---

Information represented by discrete, whole number values, resulting in a signal that changes in distinct, separate steps.

---

Example: Binary code uses 1s and 0s to represent digital information as discrete values.

Front

Sampling Rate Noun

---

[sam-pling reyt]

Back

Sampling Rate

---

The frequency at which an analog signal is measured at specific intervals to convert it into a digital signal.

---

Example: The image shows how a higher sampling rate captures more details of an audio wave, converting it to digital.

Front

Pixels Noun

---

[pik-suhls]

Back

Pixels

---

The tiny, individual picture elements or dots of color that combine to form a complete digital image on a screen.

---

Example: A screen showing how pixels combine to form a complete image, with dimensions labeled.

Front

Resolution Noun

---

[rez-uh-loo-shuhn]

Back

Resolution

---

The total number of pixels in a digital image, which directly determines the image's sharpness, detail, and overall clarity.

---

Example: The image shows how increasing the number of pixels per inch (PPI) improves image clarity.

Front

Pixelation Noun

---

[pik-suh-ley-shuhn]

Back

Pixelation

---

The jagged, blocky appearance of a digital image that occurs when the resolution is too low for the display size.

---

Example: The image shows how low resolution causes pixelation, making images look blocky.

Front

Noise Noun

---

[noiz]

Back

Noise

---

Any unwanted sound or random interference that distorts or distracts from the clarity of a transmitted signal.

---

Example: Sound waves from a megaphone cause confusion, illustrating noise pollution.

Front

Binary Noun

---

[bahy-nuh-ree]

Back

Binary

---

A method of representing information using only two digits, 0 and 1, which is the fundamental language of computers.

---

Example: This image shows how binary numbers use powers of 2 to represent values, explaining the binary system.

Front

Bit Noun

---

[bit]

Back

Bit

---

A single binary digit, which can be either a 0 or a 1, representing the smallest unit of data.

---

Example: The image shows a 'Bit' as a choice between 0 and 1, illustrating the smallest unit of data in binary.

Front

Byte Noun

---

[bahyt]

Back

Byte

---

A group of 8 bits that serves as the basic unit of data in computing, often representing a single character.

---

Example: A byte is shown as 8 bits, with labels for a bit and the base.
