I. Match words in the text with their definitions.

1. Spin A. Representation of facts, concepts or

instructions in a formalized manner suitable

for communication, interpretation or

processing.

2. Bit B. To make easy or easier; help.

3. ROM C. It can be read but not erased or overwritten.

4. RAM D. Chips that allow the user to store, erase or

correct data.

5. EPROM E. The smallest element of data.

6. To facilitate F. Chips which are used for permanent

storage.

7. Data G. Fast turning movement.

II. Identify whether the following statements are true or false. Use the model:

1) Student a: For electronic circuits the conducting (on) state represents the number zero, the nonconducting (off) state represents the number one. – Student b: Yes, that is true.

2) S. A: One major advantage of most semiconductor memory is its volatility. – S.B: No, that is wrong! Volatility is one of the disadvantages because uninterrupted electric power must be supplied not to lose the contents of memory.

1. A byte is a basic grouping of bits that the computer operates as a single unit.

2. Removable credit-card-size and smaller “flash memory” RAM cards can also provide several megabytes of permanent direct access storage for PDAs or handheld PCs.

3. Emergency transfer to other devices or standby electrical power (through battery packs or emergence generators) is not necessary if data are to be saved.

4. Nonvolatile random access memory chips are used for permanent storage.

5. When we turn on the computer, the CPU gets its first instructions from the RAM.

6. ROM can be read, erased and overwritten.

7. Users have access to the ROM, so they can change the instructions.

1. The capacity of memory chips is usually expressed in terms of ….

2. The primary storage of a computer consists of microelectronic semiconductor … ….

3. Specialized memory can help improve your computer’s ….

4. Some of the major attractions of semiconductor are its small size, great speed and… ….

5. Emergency transfer to other devices or standby electrical power is required if data are to ….

6. MRAM uses the magnetic spin of … instead of power refreshing to hold the electrical signal of one or ….
