Personal Computers. What are they?

Personal computers can be categorized by size and portability:

Desktop computers

Laptop/notebooks and netbooks

Personal digital assistants (PDAs)

Tablet computers

Wearable computers

Most of today's portable computers fall into the "laptop" class and notebookor even the smaller "netbook" class. Laptops/notebooks range from briefcase size to paperback size and many of them provide as much power as full-size computers. Netbook is the next step of getting computers smaller. People use netbooks mostly for displaying information than for any other purpose. Dont forget that netbook has no DVD-drive, you can use only flash memory cards.

PDA is hand-held computer also called Personal Communicators and Personal Intelligent Communicators. Most PDAs can connect to other computers, either through telephone lines, radio waves, or a computer cable. Many have PC card slots for attaching modems and other auxiliary devices. Most PDAs are capable of at least limited handwriting recognition, allowing

users to enter notes into the computer with a special pen-like device, stylus, rather than with a keyboard.

A Tablet PC is a complete computer contained in a touch screen. Tablet computers can be specialized for only Internet use or be full-blown, general-purpose PCs with all the options of a desktop unit. The distinguishing characteristic is the use of the screen as an input device using a stylus or finger.

A wearable computer is a very personal computer. It should be worn like a piece of clothing. A user should interact with the computer based upon context. It could be a communications device (immediate or store and forward), a recorder (visual, audio, other sensors) or a reference device (local or remote resources).

Many mass-market IBM PC compatible and Apple Macintosh personal computers are standardized to the point that purchased software is expected to run with little or no customization for the particular computer. Often memory and peripherals such as video boards and disk storage are easily upgradeable, even by the end user. Even the motherboard and central processing unit can be designed to be user-replacable. This upgradeability is, however, not indefinite due to rapid changes in the personal computer industry. A PC that was considered top-of-the-line five or six years prior may be impractical to upgrade due to changes in industry standards. Such a computer usually must be totally replaced once it is no longer suitable for its purpose. This upgrade and replacement cycle is related to new releases of the primary mass-market operating system, which tends to drive the acquisition of new hardware.

The hardware capabilities of personal computers can sometimes be extended by the addition of expansion cards connected via an expansion bus. Some standard peripheral buses often used for adding expansion cards in personal computers are AGP (a high-speed PCI bus dedicated to graphics adapters). Most personal computers as of 2009 include an AGP bus and some expansion slots.

ASWER THE QUESTIONS: 1. Which of the mentioned personal comuters do you have? 2. What are the advantages/diadvantages of each type of computers. 3. PDAs are the most popular nowadays, is it right? 4. Which type of the mentioned computers is the least popular? Why? 5. Which type of these computers do you never see? 6. What other classifications of computers do you know? 7. What is the purpose of any wearable computer? 8. Could we use any Microsoft product on Apple computers? Why? 9. Why do you think most of our computers have OS of this comany? 10. Do you know any other computer companies, besides IBM, Microsoft and Apple? 11. What options should the best copmuter have from your point of view? 12. If you have a choice what type of the discussed computers you will choose. 13. Is it right that some computers couldt be upgraded at all? 14. Is it so easy to upgrade your computer? Why? 15. Try to describe each of the above-mentioned category of PCs.

F: I have to find something suitable for me instead of my old-old computer that passed on (~ ), by the way. I cant decide what to buy a laptop or a desktop PC.

J: First, you should think over the performance and capabilities of your future machine. Then youll have to decide whether its size, power and portability will be the main features of your computer.

F: Whatdo you mean speaking about the size, power and portability?

J: These three things are the most important features to be paid attention to when choosing between laptops and desktops.

F: I see.I need light, portable and advanced computer with as much as possible communication features and

J: Wait a minute

F: with large screen and having enough power for gaming

J: Fred,stop dreaming! Lets discuss one more problem that can make you change your mind.

F: What do you mean?

J: Of course, the price! All you mentioned about concerns a laptop and it costs more than its desktop cousin. And there are also some other things you are to know before making any decision Well, Im pressed for time. Come to me this Friday well talk about them.

F: All right. Bye.

1. Your friend mixes up some things from computer language and asks you to tell the difference between laptops and netbook, if any.

2. You help your group-mate make a right choice buying a new computer.

3. Everyone talks about the disappearance of desktop PC.

Exercise 5. Choose the text. Read it and summarize key points.

A

Seiko Instruments Inc announced their first Bluetooth watch, the BT Watch. This hi-tech watch is packed into a very stylish casing. This watch is in fact an extension of your phone, and you'll be able (at first) to play around with the volume of the ringtone of your phone. It can also alert you when you have an SMS or e-mail, and it can display the number and the name of the person that is calling you. Finally, it will also alert you when the Bluetooth connection between the watch and phone is broken, so you won't forget your phone anymore.

B

The Zypad WL 1000, a new wrist-worn PC has been demonstrated to the military forces. This device, which can run Linux or Windows, is a hands-free computer which handles wireless networking and GPS tracking. It also comes with a 240 x 320 pixels touchscreen and has a battery which can last about 8 hours. It only weighs 300 grams but it will be attached at the end of your arm, so it might feel heavier than this. It could be used by healthcare or law enforcement personnel.

C

iPod-compatible footwear that tracks runners' training routines is just the beginning of a collaboration between these brands. Their first jointly produced product: the Nike+iPod Sport kit, which involves an electronic sensor inserted under the inner sole of a new Nike running shoe. That sensor talks to a small wireless receiver that attaches to Apple's iPod nanomusic player. The components work together to give voice prompts, interjected while music is playing, that tell runners how far they've gone and at what pace. The iPod will also keep track of the duration, distance, and other information on each run. The data could then be uploaded to a Mac or PC.

D

The University of Buffalo's VR lab has developed a cap for your index finger that is exquisitely sensitive to movementto the point that it can actually be used as a 3D digitizer. It has an accelerometer, a force sensor, and a motion tracker.

E

Japan's Scalar Corp. has recently introduced Teleglass T3-F Video Eyeglasses. Users enjoy the feeling of watching a 28" video screen from a distance of about 6 feet away. Video Eyeglasses solve that issue by only displaying the video to only one eye, leaving the other free to watch for the right subway stop.

Exercise 6. Translate from Russian into English.

Exercise 7. Get ready to discuss the topic Types of personal computers

GRAMMAR EXERCISES

Exercise 1. Translate, paying attention to the words in italics.

For hikers, tourists or just about anyone who likes to travel with a light load while taking digital photos, Sony has come up with a wearable GPS tracking device that'll help you keep track of where you've been. It is small enough and attached to your belt with a carbine. It records your time and location every 15 seconds. By synching the GPS clock with the timestamp on a digital still camera, your journey is archived, step by step.

Exercise 2. Put the verb in brackets into the correct form.

MICRO ELECTRONICS POWERSPEC T470

Sometimes youre just not (to look) for a whiz-bang desktop. If merely capable is more your speed, then take a gander at the PowerSpec T470. This Vista Premium desktop system (to have) some nice components and its performance is decent. But it (not to have) the styling or bells and whistles of similar desktops from other manufacturers. The system (to load) an Intel Core 2 Duo E6300 processor, 2GB of memory, and a dual-layer DVD burner. You also (to get) a 300GB SATA hard drive that will hold a lot of photos or music files, and discrete graphics in a 256MB nVidia GeForce 7300 GT card. But one item that Micro Electronics should have sprung for is an optical mouse instead of a ball mouse. The system (to be) virtually free of preloaded bloatwarethe ISP sign-ups and trial programs that you never use. But one software goody that we wish it did come with is an antivirus subscription longer than the free 90-day NOD32 antivirus/antispyware package. The PowerSpec T470 has some good hardware and (to provide) decent performance for a $1,000 multimedia system. Still, similar machines (to be) sturdier and less noisy.

Exercise 3. Correct the mistake. Each sentence has one grammar mistake.

There are no real comparison on performance between a laptop and a desktop computer. The laptop have a couple of fundamental problems to overcome which limit it. The first of these is size the smaller the machine, the less room to puts components. The second is heat the laptop is small and give less room to circulate air to cool components. Because manufacturers is constantly fighting against these problems the laptop will never truly replace the desktop.

SPEAKING-DISCUSSION

Exercise 1. Look through the statements and agree/disagree with each one. Prove your opinion using the following word expressions.

I think/I do not think; I believe/I dont believe;

I agree that/ I dont agree that; I guess; I suppose; I consider;

From my point of view; To my mind; In my opinion; To my way of thinking.

Its true that; If you ask me; As I see it;

1. All netbooks are designed to present information not create it.

2. Tablet PCs may be used where notebooks are impractical or do not provide the needed functionality.

3. Many notebook computers cannot actually be used on your lap, so they cannot really be described as a laptop this is because the main cooling air fan inlet is on the bottom.

Exercise 2. Read and translate the text and get ready to discuss its advantages and disadvantages.
