Прочитай текст та вкажіть в завданні в якому абзаці (АBCD) про це йдеться. ABCD може вживатися більше ніж один раз. Read the text and decide which paragraph (ABCD) says. ABCD can be used more than once.
Computers
(A) Representing Data All data inside a computer is transmitted as a series of electrical signals that are either on or off. Therefore, in order for a computer to be able to process any kind of data, including text, images and sound, they must be converted into binary form. If the data is not converted into binary – a series of 1s and 0s – the computer will simply not understand it or be able to process it. (B) Representing text When any key on a keyboard is pressed, it needs to be converted into a binary number so that it can be processed by the computer and the typed character can appear on the screen. A code where each number represents a character can be used to convert text into binary. One code we can use for this is called ASCII. The ASCII code takes each character on the keyboard and assigns it a binary number. (C) Representing images Images also need to be converted into binary in order for a computer to process them so that they can be seen on our screen. Digital images are made up of pixels. Each pixel in an image is made up of binary numbers. (D) Image quality Image quality is affected by the resolution of the image. The resolution of an image is a way of describing how tightly packed the pixels are. In a low-resolution image, the pixels are larger so fewer are needed to fill the space. This results in images that look blocky or pixelated. An image with a high resolution has more pixels, so it looks a lot better when you zoom in or stretch it.
