TEXT B
Is "Laptop" Being Phased Out?
Is there really a difference between a laptop and notebook computer? For most people shopping for a mobile (or portable) computer today, the short answer is “no”. In fact, the difference between a laptop and notebook today is mainly what the manufacturer chooses to call its product. Technically and traditionally, the difference between the two is a matter of size.
Notebook computers typically weigh less than six pounds and are small enough to fit easily in a briefcase. Laptop computers are small enough too that they can sit on your lap. Nowadays, laptop computers are more often called notebook computers, though technically laptops are somewhat larger in size than notebooks.
The laptop was originally designed to be similar to a desktop, but be small and light enough. For this reason, years ago, a laptop had more features than notebooks did, but the tradeoff was it was also a larger and heavier than a notebook. This is because the notebook style of portable computers was for mobility, not just portability. To be a more mobile device, the notebook was a thinner design and it weighed less than the laptop, simply because it didn't come packed with features and multiple devices and drives.
Today technology allows devices to be smaller and better for mobile computing by design, so the size of portable computers is decreasing.
Another reason the term “laptop” is becoming used not often is because a portable "comparable to desktop" system today could easily lead to heat discomfort if left on your lap for long periods of time. By calling a laptop a notebook, it also removes the association that the portable device is well-suited to being used only on your lap.
People often call their notebook a laptop and use the two words interchangeably. However, most mobile computer manufacturers stopped using the term “laptop” completely; they use the term “notebook.”
At present netbooks are a new category of laptops. It's an inexpensive, lightweight machine which is powerful enough for the basic, day-to-day, Internet-based tasks that people use a regular laptop for.
At the same time, today's netbooks aren't perfect. Since they are such small, inexpensive devices, they include processors, memory, and hard disks several generations behind the ones found in regular notebooks. Even so, the potential is there for netbooks to become mainstream devices.

2.1. How would you describe what computer hardware is to someone who knows a little about computers? Work in pairs or small groups.
2.2. Now read the text and try to describe computer hardware again using the key vocabulary in bold type.
Computer hardware refers to the physical parts of a computer and related devices. Internal hardware devices include motherboards, hard drives, and RAM. External hardware devices include monitors, keyboards, mice, printers, and scanners.
The internal hardware parts of a computer are often referred to as components, while external hardware devices are usually called peripherals. Together, they all fall under the category of computer hardware. Software, on the other hand, consists of the programs and applications that run on computers. Because software runs on computer hardware, software programs often have system requirements that list the minimum hardware required for the software to run.

2.3. Decide if the statements are true (T) or false (F). Read Text A to check your answers.
1. Hardware is known as something you can actually touch.
2. The pages and the ink of a book are the hardware analogy.
3. The main memory refers to physical memory that is internal to the computer.
4. There are two different types of memory: the main memory and the random access memory.
5. Devices which can be connected to the CPU are known as
peripherals.
6. A keyboard is the most commonly used output device.
7. To display the processed data an input device is used.
8. Mass storage devices retain data even when the computer is turned off.
TEXT A
The Main Pieces of Hardware
Hardware refers to objects that you can actually touch, like disks, disk drives, display screens, keyboards, printers, boards, and chips. In contrast, software is untouchable. Software exists as ideas, concepts, and symbols, but it has no substance.
Books provide a useful analogy. The pages and the ink are the hardware, while the words, sentences, paragraphs, and the overall meaning are the software. A computer without software is like a book full of blank pages – you need software to make the computer useful just as you need words to make a book meaningful.
The most important item of hardware is the CPU (Central Processing Unit). This is the electronic unit at the center of the computer system. It contains the processor and the main memory.
The processor is the brain of the computer. It does all the processing and controls all the other devices in the computer system.
The main memory is the part of the computer where programs and data being used by the processor can be stored. It refers to physical memory that is internal to the computer. The word main is used to distinguish it from external mass storage devices such as disk drives. Another term for main memory is RAM.
RAM (pronounced ramm, acronym for random access memory) is a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.
All the other devices in the computer system, which can be connected to the CPU, are known as peripherals. These include input devices, output devices and storage devices.
An input device is a peripheral, which enables information to be fed into the computer. The most commonly used input device is a keyboard.
An output device is a peripheral, which enables information to be brought out of the computer, usually to display the processed data. The most commonly used output device is a monitor or VDU (Visual Display Unit). Another common output device is a printer. This prints the output of the CPU onto paper.
A mass storage device is a peripheral used for the permanent storage of information. It has a much greater capacity than the main memory. Mass storage is distinct from memory, which refers to temporary storage areas within the computer. Unlike main memory, mass storage devices retain data even when the computer is turned off. The main types of mass storage are various disks.
These are the main pieces of hardware of any computer system whether a small “micro” or a large mainframe system.
2.4. Match each piece of hardware on the left with its function on the right.
1. Storage device | a. displays the processed data. |
2. Input device | b. holds the programs and data being used by the processor. |
3. Output device | c. does all the processing and controls the peripherals. |
4. Main memory | d. allows data to be entered. |
5. Processor | f. provides permanent storage for programs and data. |
2.5. Fill in the gaps using the words from the box.
keyboard input unit requirements graphics the CPU
arithmetic control input calculation
_______ devices are used to supply the values needed by the computer and instructions to tell the computer how to operate on the value. _______ vary greatly from machine to machine.
Information is usually entered into a computer via a _______, with the characters typed on the screen. In English speaking countries the keyboard would have the QWERTY(1) layout. Many computers provide graphics commands which can be used to build up pictures. _______ are very important for the interface between the human user and the computer.
The arithmetic unit of a digital computer performs the actual work of computation and calculation. It carries out its job by the use of logic circuits. Modern computers use components called integrated circuits.
The control unit of a digital computer is an administrative or switching section. It receives information entering the machine and decides how and when to perform operations. It tells the arithmetic unit what to do, where to get the necessary information. It knows when the arithmetic unit has completed a ______, and it tells the arithmetic unit what to do with the results and what to do next.
The _______ unit and the ______ unit are usually grouped together in a computer and are the central processing unit or CPU. The
