Brute Force Hacking
Byte
Cable Modem (CM)
A technique used to find passwords or encryption keys. Force Hacking involves trying every possible combination of letters, numbers, etc. until the code is broken.
A set of bits that represent a single character. There are 8 bits in a Byte.
A cable modem is a device that enables you to hook up your computer to a local cable TV line and receive data at about 1.5 Mbps. This data rate far exceeds that of the prevalent 28.8 and 56 Kbps telephone modems, and up to 128 Kbps of ISDN that is about the data rate available to subscribers of Digital Subscriber Line (DSL) telephone service. A cable modem can be added to or integrated with a set top box that turns your TV set into an Internet channel. For computer attachment, the cable line must be split so that part of the line goes to the TV set and the other part goes to the cable modem and the computer.
A cable modem is more like a network interface card (NIC) than a computer modem. All of the cable modems attached to a cable TV company coaxial cable line communicate with a Cable Modem Termination System (CMTS) at the local cable TV company office. All cable modems can receive only from and send signals to the CMTS, but not to other cable modems on the line.
