Task III. Give equivalent of the following computer word combs with nouns used as modifiers.
Host processor, graphic chips, high-speed general purpose microprocessor;
High-end CPU; CAD application; lazer printers; chip process technology; development effort, application programming interfaces; frame buffer capability; floating-point computational power; stock option pricing determination
Task IV. Translate & remember the following phrases, make sentences of your own, using these phrases:
In addition to; such as…; to find one’s way into …; to focus on ; the back of smth; to be compatible with; the most commonly used…; low-end PC; to force smb to do smth; to find itself competing for; in certain circumstances, to yield results; forty times faster than the conventional CPU's
Task V. Topics for discussion:
1).Tell about the history of the development of modern GPU’s ( from early 1980 up to the present)
2). Dwell on the specific features of GPU’s
3).What are drawbacks and merits of integrated graphics solution?
4). How did the advances in GPU technology effect the computer market?
Task VI. Role-play
Play a game “Marketing”
People involved in the game:
salesmen, advertising agents, consumers of goods.
Advertising plays a key role in trade. If you want to launch a product in a market you must advertise it. TV and radio are the best for some lines, magazines and trade papers for others. But a human contact is the best way to win a customer.
Suppose, you are a sales manager or an advertising agent and you want to advertise your merchandise. The goods to be advertised are a personal computer, video card, mouse, keyboard, web camera, etc.
Rules of the Game.
Salesmen one by one introduce their production to prospective customers. A person who has managed to convince his audience that his model is the best is a winner. The customers decide who is a winner by a majority vote. The game can be arranged as a question-and-answer session.
Task VII. What do the following acronyms stand for? Match the equivalents.
CPU, GPU, GPL, API, PCI, DVD, VCD, GDI, AGP, CAD

Unit 3. Computer display
Task I. Key vocabulary.
Find the Russian equivalents of the following words and word combinations:
Device, to comprise, cathode ray tube, to coat, blanking, display resolutions, persistence, to occur, to gain, to render, dualhead-Using, triplehead-Using, display assembly, command option.
Task II.
1) Read texts to comprehend its subject matter and to note the terminological words and word combinations.
2) Look through texts below to copy out the key words and sentences containing the main idea of the texts.
3) Make use of these key words and sentences to compile a short topic to be presented to your classmates at the classroom.
4) After this, try to make common Abstract (orally or in writing).
A computer display monitor, usually called simply a monitor, is a piece of electrical equipment which displays viewable images generated by a computer without producing a permanent record. The word "monitor" is used in other contexts; in particular in television broadcasting, where a television picture is displayed to a high standard. A computer display device is usually either a cathode ray tube or some form of flat panel such as a TFT LCD display. The monitor comprises the display device, circuitry to generate a picture from electronic signals sent by the computer, and an enclosure or case. Within the computer, either as an integral part or a plugged-in interface, there is circuitry to convert internal data to a format compatible with a monitor. vdu is also the most commonly used output device.
Cathode ray tube
T
he
CRT or cathode ray tube, is the picture
tube of a monitor. The back of the tube
has a negatively charged cathode. The electron gun shoots electrons
down the tube and onto a charged screen. The screen is coated with a
pattern of dots that glow when struck by the electron stream. Each
cluster of three dots, one of each color, is one pixel.
CRT Computer display pixel array (right)
The image on the monitor screen is usually made up from at least tens of thousands of such tiny dots glowing on command from the computer. The closer together the pixels are, the sharper the image on screen. The distance between pixels on a computer monitor screen is called its dot pitch and is measured in millimeters. Most monitors have a dot pitch of 0.28 mm or less.
There are two electromagnets around the collar of the tube which deflect the electron beam. The beam scans across the top of the monitor from left to right, is then blanked and moved back to the left-hand side slightly below the previous trace (on the next scan line), scans across the second line and so on until the bottom right of the screen is reached. The beam is again blanked, and moved back to the top left to start again. This process draws a complete picture, typically 50 to 100 times a second. The number of times in one second that the electron gun redraws the entire image is called the refresh rate and is measured in hertz (cycles per second). It is common, particularly in lower-priced equipment, for all the odd-numbered lines of an image to be traced, and then all the even-numbered lines; the circuitry of such an interlaced display need be capable of only half the speed of a non-interlaced display. An interlaced display, particularly at a relatively low refresh rate, can appear to some observers to flicker, and may cause eyestrain and nausea.
