They understand machine code, i.e. Binary Digits.
TV converter boxes are used to convert signals which cannot be understood by your TV into a signal which can be understood. A common use is to translate analog signals into digital ones.
Computers run on a binary code that consists of ones and zeroes, no other digits. Computer languages are all based on what is called machine language, which is written in binary, but other computer programming languages can be written in other ways, as long as they eventually translate into machine language.

The word modem is actually made of two words: "Modulator" and "Demodulator". In the days of dial-up networking, a modem's job is to turn the digital signal of your computer into an analogue form that can then be transmitted down a telephone line to another computer. When the computer at the other end receives it, it's own modem will then turn the analogue signal back into a digital one that the computer can understand. Now that many phone lines are digital, a modem's job is to translate the computer's data into a form that's acceptable for the telephone line (e.g. ADSL) and of course translate it back again at the other end.
An optical scanner can read text or illustrations printed on paper and translate the information into a form the computer can use. A digital camera encodes digital images and videos digitally and stores them for later reproduction.
Modem in fact acts as an interpreter. When computer exchanges datas with other computers in internet,it has to take the assistance of telephone. But computer understands digital signal whereas telephone analog signal. For making reconciliation between the two requires one interpreter who can convert analog to digital and digital to analog. Modem's activity is to convert analog signal from telephone to digital understood by computer and vice verse.
