numbers, trade secrets, and private personal messages. A passive receiver that records a copy of every packet that flies by is called a packet sniffer. Sniffers can be deployed in wired environments as well. In wired broadcast environments, as in many Ethernet LANs, a packet sniffer can obtain copies of broadcast packets sent over the LAN. As described in Section 1.2, cable access technologies also broadcast packets and are thus vulnerable to sniffing. Furthermore, a bad guy who gains access to…

It’s hard to believe in 1969 that there was basically a space ship created to land on the moonhaving a man walk the first steps there. At the time small objects of new technology was being created such as a mouse for a computer, ATM’s, barcode scanners. Comparing the new technology being created at that time to a space ship on the moon with men aboard it’s difficult to believe; however, a few years after…

CPU A CPU (which is also known as a central processing Unit) is basically the part of the computer of where most of the processing of calculations takes place. some people refer to it as the “brains” of the computer. Processors are used in all types of computers The CPU plugs into something known as a CPU socket which is located on the mother and this socket delivers electrical contact to the microprocessor and to something known as a printed circuit board. In the case of chips with have a big…
