partial ['pRSl] – частичный solution (to) [sq'lu:Sn] – решение (чего-л.) cache memory ['kxS 'memqri] – кэш-память speed [spi:d] – скорость recent ['ri:snt] – последний, недавний amount [q'maunt] – количество to have an impact (on) [hxv qn 'impxkt] – иметь, оказывать влияние (на) tremendous [trq'mendqs] – огромный II. Answer the following questions: What is memory? What does memory consist of? What types of memory are there? Which type of memory is permanent? temporary? What does the term “non-volatile” mean? What are the functions of ROM instructions? Can the data in random access memory be changed? What is the purpose of RAM? How does the amount of RAM affect the computer’s speed? How does the CPU access memory locations? What is a memory address? What are the types of RAM? What is the difference between these two types? What do you know about cache memory? III. Tell whether the following statements are true or false: The CPU can hold large amounts of data permanently. Memory consists of chips on the motherboard or on a small circuit board. The data in ROM can be changed. The amount of ROM has an impact on the computer’s speed. ROM is a form of cache memory. RAM stands for “readable access memory”. If a memory chip loses its contents when the computer’s power is turned off, the type of memory is said to be volatile. More RAM can make a computer run faster. A memory address is a number that indicates a location on a memory chip, and helps the CPU locate data in memory. Dynamic RAM chips do not need to be recharged with electricity very often, and can hold their contents longer than static RAM chips. Static RAM is faster than dynamic RAM. Cache memory is a type of high-speed memory that contains the most recent data. IV. Fill in the blanks: Memory allows the CPU to _________ and ________ data quickly. A set of start-up instructions in ROM checks for ________ and for ________ on the computer's disk drives. Because RAM is ______________, it needs a constant supply of power. Memory that can be instantly changed is called _____________ , or ____________. The purpose of RAM is to _________ programs and data while they are in use. The ________ RAM a computer has, the _______ it can do and the _______ it can perform certain tasks. A __________ is a number that indicates a location on the memory chips. Dynamic RAM (DRAM) must be __________, or recharged with electricity frequently. Static RAM can hold its __________ longer than dynamic RAM. Cache memory is a type of __________ memory that contains the most recent data and instructions loaded by the CPU. V. Choose the right answer: 1. Registers are built into the Motherboard c. CPU RAM d. None of the above 2. Another term for random access memory is a. Read-only memory c. Short-term memory b. Storage d. Read/write memory 3. In this type of memory chip, data cannot be changed. a. Volatile c. Random access memory b. Nonvolatile d. All the above 4. This type of RAM stores data even when the power is turned off. a. SRAM c. ROM b. DRAM d. All the above 5. In this type of memory programs and data can be written to and erased from as needed. Read/write memory c. Cache memory Read-only memory d. All the above 6. This type of memory must be refreshed frequently. SRAM c. ROM DRAM d. RAM 7. The amount of this type of memory has an impact on the computer’s speed. Cache memory c. ROM Non-volatile memory d. All the above 8. This type of memory holds programs and data while they are in use. ROM c. RAM Non-volatile d. All the above VI. Match each item to the correct statement below: Memory c. ROM RAM d. Cache memory Described as volatile. 4. Stores start-up instructions. Randomly accessed space. 5. Stores programs and data in use. The more, the better. 6. Described as non-volatile. a. Volatile c. SRAM b. Non-volatile d. DRAM Holds its contents longer. Slower type of random access memory. Loses its contents when the power is turned off. Read-only memory belongs to this type. VII.
