READING

1. Read the text and decide whether these sentences are true or false.

RAM and ROM

The programs and data which pass through the processor must be loaded into the main memory in order to be processed. Therefore, when the user runs a program, the CPU looks for it on the hard disk and transfers a copy into the RAM chips. RAM (random access memory) is volatile – that is, its information is lost when the computer is turned off. However, ROM (read only memory) is non-volatile, containing instructions and routines for the basic operations of the CPU. The BIOS (basic input/output system) uses ROM to control communication with peripherals. RAM capacity can be expanded by adding extra chips, usually contained in small circuit boards called dual in-line memory modules (DIMMs).

Buses and cards

The main circuit board inside your system is called the motherboard and contains the processor, the memory chips, expansions slots, and controllers for peripherals, connected by buses – electrical channels which allow devices inside the computer to communicate with each other. For example, the front side bus carries all data that passes from the CPU to other devices.

The size of a bus, called bus width, determines how much data can be transmitted. It can be compared to the number of lanes on a motorway – the larger the width, the more data can travel along the bus. For example, a 64-bit bus can transmit 64 bits of data. Expansion slots allow users to install expansion cards, adding features like sound, memory and network capabilities.

1. Random access memory is temporary. – T

2. RAM capacity is increased by adding extra chips. – T

3. ROM doesn’t include instructions needed by the CPU. – F

4. The motherboard is used to refer to the main printed circuit board. – F

5. The benefit of having expansion slots is the possibility of installing expansion cards. – T

2. Read the text and fill the gaps 1–6 with the most suitable missing sentences A–G. There is one extra option which you don’t need to use.

E INK

In the past, flickering screens made electronic books and newspapers uncomfortable to read for long periods. The American company, E Ink, has solved this problem by producing electronic ink. (1) _____. They appear on screens which are as thin as paper and can be bent without causing damage.

Different companies have released products which use this new technology. (2) _____. Sony have released their Reader device. It is no thicker than a paperback and weighs just 250 grammes. (3) _____. It accepts both memory sticks and SD flash memory cards. Sony claims the batteries will allow up to 7,500 page turns.

Everything isn’t perfect yet in the e-ink world. There are several disadvantages to contend with. (4) _____. Work on colored e-ink is underway. Second is that the screen refresh rate is low compared to current LCD technology. (5) _____. A third disadvantage is that an «after-image», or «ghost» may be visible after changing the display. As this technology continues to mature, these problems will either be reduced or eliminated.
