Understanding Computer Peripherals and Memory Units

Let's carefully examine each statement to determine its truthfulness regarding computer peripherals and memory units.

Printer and Plotter Devices Analysis

Statement I: "Printer is an output device, whereas Plotter is an input device."

• A Printer is a peripheral device that produces a hard copy (physical copy) of electronic data stored on a computer. Since it takes information from the computer and displays it in a physical format, it is classified as an output device. This part of the statement is correct.
• A Plotter is also an output device, similar to a printer, but it specializes in printing vector graphics. Plotters are often used for large-format printing, such as architectural blueprints, engineering designs, and maps. They take digital data and convert it into large-scale drawings or images. Therefore, a plotter is an output device, not an input device.

Since the statement claims that a Plotter is an input device, this part of the statement is false. Consequently, the entire Statement I is False.

Memory Unit Conversions

Statement II: "1 MB is equivalent to 1024 Bytes."

To evaluate this statement, let's recall the standard hierarchy of digital memory units:

• $1 \text{ Byte} = 8 \text{ bits}$
• $1 \text{ Kilobyte (KB)} = 1024 \text{ Bytes}$
• $1 \text{ Megabyte (MB)} = 1024 \text{ Kilobytes (KB)}$
• $1 \text{ Gigabyte (GB)} = 1024 \text{ Megabytes (MB)}$

Now, let's calculate the value of $1 \text{ MB}$ in Bytes:

We know that:

• $1 \text{ MB} = 1024 \text{ KB}$
• $1 \text{ KB} = 1024 \text{ Bytes}$

So, substituting the value of KB into the MB conversion:

The statement claims that $1 \text{ MB}$ is equivalent to $1024 \text{ Bytes}$, which is incorrect. $1 \text{ MB}$ is significantly larger than $1024 \text{ Bytes}$.

Therefore, Statement II is also False.

Conclusion for Both Statements

Based on our analysis:

• Statement I: False
• Statement II: False

Both statements are false.
