Digital technology is the same as the used in digital watches, or the time display on a microwave oven. Digital is about using the exact numbers to tell the time. By being digital transmission of data became easy. Sound, images and document are relayed faster and stored conveniently through this system.
Modem provides internet, WiFi, we can connect multiple devices to internet through modem.
Modem provides radiation of short wavelength and the transmitter in your mobile phones and computers convert those radiations into digital signals and vice-versa.

Answer:
-3874₁₀ = 1111 1111 1111 1111 1111 1111 1101 1110₂
Explanation:
2's complement is a way for us to represent negative numbers in binary.
To get 2's complement:
1. Invert all the bits
2. Add 1 to the inverted bits
Summary: 2's complement = -N = ~N + 1
1. Inverting the number
3874₁₀ = 1111 0010 0010₂
~3874₁₀ = 0000 1101 1101₂
2. Add 1 to your inverted bits
~3874₁₀ + 1 = 0000 1101 1101₂ + 1
= 0000 1101 1110₂
You can pad the most signigicant bits with 1's if you're planning on using more bits.
so,
12 bits 16 bits
0000 1101 1110₂ = 1111 0000 1101 1110₂
They asked for double word-length (a fancy term for 32-bits), so pad the left-most side with 1s' until you get a total of 32 bits.
32 bits
= 1111 1111 1111 1111 1111 1111 1101 1110
