FiOS is a special type of data network that is offered to Fiber Optic Subscribers. The existing FiOS network is at a industry high where speed is concerned, as it offers 150 Megabits/second downloads with as much as 35 Megabits/second upload. The speeds of up to 50 Megabits/ second are offered to co

A null modem cable will enable you to connect two computers together for serial communications. It is a particularly designed cable that permits anyone to connect two computers directly to each other via their communications ports called RS-232 ports. Serial communications with RS232 is one of the o

RG-58 is a coaxial cable that is used for wiring purposes. A coaxial cable, in general, consists of an inner conductor that is surrounded by a spacer. The coaxial cable is electrically charged and sometimes consists of different uninsulated conductors that remain entangled with one another. The insu

The system that helps connect a computer to an Ethernet network is called an Ethernet card. Another name for such a card is Network Interface Card (NIC). It can be inserted into one of the slots provided on the motherboard of the computer. Each of these cards has a unique identification number, know

A cable tie, also commonly called a zip tie, is a length of strong Nylon lined with a gear rack. On one end of the tie is a small square case through which you can feed the other end of the tie. The teeth on the tie are arranged in a saw-tooth pattern, and the case contains a ratchet which locks aga

RG-8 is a 50-ohm coaxial cable that is used for radio transmission (for instance in amateur radio or CB). Recently, they have become an integral part of computer networks, as they can increase connectivity. One of the first things that someone will notice about RG-8 cables is that they are huge when
