Прочитайте текст и определите, какой из заголовков соответствует тексту.
In a broadcast system, a central high-powered broadcast tower transmits a high-frequency electromagnetic wave to numerous low-powered receivers. The high-frequency wave sent by the tower is modulated with a signal containing visual or audio information. The antenna of the receiver is then tuned so as to pick up the high-frequency wave and a demodulator is used to retrieve the signal containing the visual or audio information. The broadcast signal can be either analogue (signal is varied continuously with respect to the information) or digital (information is encoded as a set of discrete values).

Signals can be either analogue or digital. In an analogue signal, the signal is varied continuously with respect to the information. In a digital signal, the information is encoded as a set of discrete values (for example ones and zeros). During transmission the information contained in analogue signals will be degraded by noise. Conversely, unless the noise exceeds a certain threshold, the information contained in digital signals will remain intact. This noise resistance represents a key advantage of digital signals over analogue signals.

What is the Central Processing Unit used for?
The Central Processing Unit (CPU) is the brain of the computer. It reads and interprets software instructions and coordinates the processing activities that must take place. The design of the CPU affects the processing power and the speed of the computer, as well as the amount of main memory it can use effectively. With a well-designed CPU in your computer, you can perform highly sophisticated tasks in a very short time.
It only coordinates the processing activities.

What is ROM?
Memory is the system of component of the computer in which information is stored. There are two types of computer memory: RAM and ROM.
RAM (random access memory) is the volatile computer memory, used for creating, loading, and running programs and for manipulating and temporarily storing data;
ROM (read only memory) is nonvolatile, nonmodifiable computer memory, used to hold programmed instructions to the system.
The more memory you have in your computer, the more operations you can perform.
It is the volatile computer memory, used for creating, loading, and running programs and for manipulating and temporarily storing data.
It is nonvolatile, nonmodifiable computer memory, used for temporarily storing data.
It is main memory.
It is nonvolatile, nonmodifiable computer memory, used to hold programmed instructions to the system.
