THE FUTURE OF THE INTERNET

It is estimated that thirty five to forty millions users cur­rently are on the Internet. According to a recent statistics, an average Internet call lasts five times as longer as the average regular telephone call. 10 percent of the Internet calls last 6 hours or longer. This can cause an overload and, in turn, cause telephone network to fail. The local network was designed for short calls which you make and then hang up, but Internet calls often occupy a line for hours. With so many users in the Inter­net and their number is growing by 200 percent annually, it certainly provides new challenges for the telephone companies. The Internet, up to the beginning of the 90s, was used only to read a different texts. Then in the early 90's, a way was made to see pictures and listen to a sound on the Internet. This break through made the Internet to be most demanded means of communication, data saving and transporting.

However, today's net is much more than just pictures, text and sound. The Internet is now filled with voice messages, video conferencing and video games. With voice massages, users can talk over the Internet for the price of the local phone call.

Nowadays we no longer have to own a computer to access the Internet. Now, devices such as Web TV allow our televi­sion to browse the Web and use Electronic Mail. Cellular phones are now also dialing up the Internet to provide e-mail and answering machine services. The telephone network was not designed and built to handle these sorts of things. Many telephone companies are spending enormous amounts of mo­ney to upgrade the telephone lines.

K. Kao and G. Hockman were the first to come up with the idea of using fiber optic cables, as opposed to copper wire, to carry telephone signals. Fiber optics uses pulses of light to transmit binary code, such as that used in computers and other electronic devices. As a result the amount of bandwidth is inc­redibly raised. Another solution for the problem is fast mo­dems which satisfy the need for speed.


By accessing the Net through the coaxial cable that pro­vides television to our homes, the speed can be increased 1,000 fold. However, the cable system was built to only send infor­mation one way. In other words, they can send stuff to us, but we can't send anything back, if there is no modem available.

Yet another way is being introduced to access the Inter­net, and that is through the use of a satellite dish just like the TV dishes currently used to deliver television from satellites in space to your home. However, like cable connection, the in­formation can only be sent one way.

Faster ways of connecting to the Internet may sound like a solution to the problem, but, just as new lanes on highways attract more cars, a faster Internet could attract many times more users, making it even slower than before.

To help solve the problem of Internet clogs, Internet providers are trying new ways of pricing for customers. So, in business time any connection to Net cost more than your con­nection in the night.

In conclusion, I should add that if we want to keep the Inter­net usable and fairly fast, we must not only improve the telephone lines and means of access, but also be reasonable in usage.

Disks and drivers

A. Magnetic storage

Magnetic devices store data magnetically. A disk drive spins the disk at a high speed and reads its data or writes new data onto it.

  • A floppy disk drive uses 3.5 inch diskettes which can only hold 1.44 MB of data; it’s often called A: drive and is relatively slow.

  • Most PCs have one internal hard disk, usually called C: drive, which can hold several gigabytes of data. It’s used to keep the operating system, the programs and the user’s files easily available for use.

  • When you format a disk, or prepare it for use, it’s surface is devided into concentic circles called tracks. Each track is further divided into a number of sectors. The computer remembers where information is stored by noting the track and sector numbers in a directory.

  • The average time required for the red\white heads to move and find dadt is called access time; it is measured in milliseconds (ms). Don’t confuse “access time” with transfer rate”, the rate of transmission of data from the disk to the CPU (e.g. 15 megabytes per second).

  • A portable hard drive is an external unit with the drive mechanism and the media all in one sealed case. You can use it to make a backup, a spare copy of your files, or to transport data between computers.

Generations of Computers.

There are two main types of computers, analog and digi­tal, although the term computer is often used to mean only the digital type, because this type of computer is widely used today.

That is why I am going to tell you about digital computers.

Everything that a digital computer does is based on one operation: the ability to determine: on or off, high voltage or low voltage or — in the case of numbers — 0 or 1 or do-called binary code. The speed at which the computer performs this simple act is called computer speed. Computer speeds are mea­sured in Hertz or cycles per second. A computer with a ”clock speed” of 2000 MHz is a fairly representative microcomputer today. It is capable of executing 2000 million discrete opera­tions per second. Nowadays microcomputers can perform from 800 to over 3000 million operations per second and supercom­puters used in research and defense applications attain speeds of many billions of cycles per second.

Digital computer speed and calculating power are further enhanced by the amount of data handled during each cycle.

Except two main types of computers, analog and digital there are eight generations of digital computers or processing units. The first generation was represented by processing unit Intel 8086. The second generation central processing unit was represented by processing unit Intel 80286, used in IBM PC AT 286. The third generation is Intel 80386, used in IBM PC AT 386. The microprocessors of the fourth generation were used in computers IBM PC AT 486. There are also central pro­cessing units of the fifth generation, used in Intel Pentium 60 and Intel Pentium 66, central processing units of the sixth generation, used in computers Intel Pentium 75, 90, 100 and 133. Few years ago appeared central processing units of sev­enth and eighth generations. They are much more powerful and can perform from 2000 to over 3000 million operations per second.
