.... for login is physically in the next room or halfway around the globe. A common program feature is the ability to emulate several diverse types of terminals-- ANSI, TTY, vt52, and more. In the early days of networking some ten to fifteen years ago, the "internet" more or less consisted of telnet, FTP (file transfer protocol), crude email programs, and news reading. Telnet made library catalogs, online services, bulletin boards, databases and other network services available to casual computer users, although not with the friendly graphic user interfaces one sees today. Each of the early internet functions could be invoked from the UNIX prompt, however, each of them use ....

.... to the police speed-detecting equipment. It mixes a portion of the radar signals with background clutter and bounces it back to the squad car by way of wave guide antenna, which effectively confuses the computer inside the radar gun. Police radar takes five to ten speed measurements per second of the vehicle. The Phazer sends two different signals to the radar, so the final result is that police radar can not verify the speed of the vehicle and displays no speed at all. The Phazer also protects your vehicle from Lidar guns which use distance over time to detect the speed of the vehicle. The Phazer sends an invisible infared signals to the Lidar gun, this way th ....

.... PCs. Most of the home users prefer Intel Based PCs, so they can run Linux on their computers (Windows can only run on Intel Based PCs). Because of this Linux has the potential to be more attractive to a larger number of users and a larger variety of users. (Linux.com) Linux has a powerful security system. It is almost impossible to write a virus for Linux because it must be 30-40 MB. Also, it has firewall system to protect the network from hackers. This minimizes the number of viruses capable of affecting a Linux system. If we think about it, there are many viruses for Windows that can harm your system. Linux is a stable Operating System. You can kill an individual ....

.... want, or to look for well-known items previously recommended by others. In "pay-per-use" environments, people tend to follow more traditional paths of discovery, and seldom explore totally unexpected avenues. "Pay-per-use" environments discourage browsing. Imagine how a person's reading habits would change if they had to pay for each article they looked at in a magazine or newspaper. Yet many of the most interesting things we learn about or find come from following unknown routes, bumping into things we weren't looking for. (Indeed, Thomas Kuhn makes the claim that, even in the hard sciences, real breakthroughs and interesting discoveries only come from following these unco ....

.... data and will have gained nothing, unless they can figure out the decryption algorithm and obtain the key. This is why the key is never to be sent with the message, and has to be kept secret at all cost. If the key is compromised, the sender and the encrypted data is no longer safe. The sender and the receiver then usually agree on a new key to prevent any further damage. In ancient Greece, around 550 Bc, messages were sent encoded to generals and could only be decoded using special staff keys. The key actually consisted of a physical object, which was applied on the message to get the decrypted version of it. In 50 Bc., one of the most simple cryptographic algorith ....

.... to be very sensitve data storage mediums. These Disks have numerous advantages and disadvanteges. Even though floppies are used so commonly they are also not very dependable. They have numerous conditions under which they should normally be kept. For example: the actuall magnetic disk inside the hard cover of the disk must NEVER be touched, the magnetic disk inside, must be protected by the metallic sliding shield, the disk must always be within the temperature of 50° to 140° Fahrenheit and the disk must never be bought near a magnet! (3M Diskettes) There are many such hazards to computer disks. Problems caused by magnets are very common. A floppy can be damaged unknow ....

.... and there is no way to get to a library before the essay is due. There is no hope of getting a passing grade, right? But wait, you have a computer, a modem, and the internet! You are saved! All you have to do is log on the internet, type in a keyword about your topic, and search. Instantly, you can get tons of information about your topic. The internet links people together into a web of networks and shared software using computer terminals and telephone lines or wireless radio connections.The basic internet was formed about 4 or 5 years ago by the United States government with the idea to pass information between themselves rapidly and efficently. Groups ....

.... They were looking to increase the efficiency of there restaurants through the use of computer technology. During there search they found systems but none meeting there total needs. That is why the Fullers created the company, (R.D.C) Restaurant Data Concepts. RDC keeps developing better and more efficient equipment to be used in the food service industry. Overall, I feel that POSitouch is well worth the initial expense. It should be looked at as an investment, saving time, and money in all areas needing tight controls. This management tool has been shown to cut labor, and food costs in many food service establishments, not to mention the speed of the system, which ....
