Different Types of Cables

There are many types of cables out there that can be used with networking and telecommunications related devices. There are those that can do a variety of different things and can be used with an assortment of technological equipment. They are basically the link between a device and the power that makes that mechanism run. Most transmit signals between electrical equipment. The type of signal that is transmitted depends on what type of cable is being used. Some different types of cables are fiber optic patch, firewire, serial, and fiber optic.

Fiber optic patch cables are employed when connecting one fiber optic device to another and are used to send a signal. The various mechanisms that are used in fiber optics, data communications, or telecommunications technology are connected with patch cables or cords.

With this type of patch wiring, strands are used as opposed to wires because there is less of a chance that the signals that are being sent between devices will be lost. The patch cords that are usually used in this form of technology are made in a variety of colors so that they are distinguished without problems.

Different Types of Cables

Firewire cables are designed to connect firewire peripherals, external devices that are used to increase the potential of the communication system, to firewire enabled computers. When the connection is made by the firewire, between the two mechanisms it makes it easier for information to be shared and enables the data to be accessed at a faster pace.

Firewires are similar to USB cables. They transfer data at a very fast pace, are easy to use, and have plug-and-play capabilities. Firewires transfer their data amid digital devices and are used often in audio and video equipment.

Serial cables are those that connect serial devices to serial communication ports. They are able to transmit data using actual serial communication. In most cases a serial line will use an RS-232 standard which is for serial binary data signals that are used when linking data circuit-terminating equipment and data terminal equipment.

Fiber optic cables are network lines that are made out of a bundle of thin strands of glass. This technology uses the glass fibers to transmit digital data. The messages and information that are transmitted merge into a carrier signal and are adjusted to light waves. The digital information that is carried through these lines is sent over long distances.

Each optical fiber that is within a fiber optic wiring is made up of the core, the cladding, and the buffer coating. In a single one there are usually hundreds of thin strands that are all bundled under a covering.

Computer Networking - Elements and Components

When studying computer networks, one must consider the main elements that will compromise the computer network. The main elements that must be considered will be presented below:

1. Message: the message is a generic term that scribes the data to be transmitted. It can be email, webpage, user call, instant message, or any other forms. The message is generated by the end user that needs to make the transmission. This message will be fed to the network later.

Generally, the message is generated using software installed on computer. For example, if the message is email, it will be generated by email programs such as outlook. Also if the message is a web page request, it will be generated by a browser such as internet explorer. It can also be generated by a chatting program is it represents a call by the user.

2. Medium: the medium is the transmission path over which the data will be transmitted. Is is used to connect the end user with the network device or to connect the network devices with each other.

Many types exist for the medium. Mainly it can be wired or wireless medium. The wired medium can be copper or optical fibers. The copper is subdivided into coaxial cables and twisted pairs. The copper wires carry data as electrical pulses while the optical fiber carry data as light pulses. The wireless medium carries data as electromagnetic waves. Each of the above mediums has its own specifications and used according to the application.

3. Devices: there are two basic types of devices in the network: end user devices and network devices. The end user device is considered to be the source of the message. It can be a client computer or an IP phone. The function of the end user device is to send the data to the network.

On the other hand, the network devices are used along with the medium to forward the data generated by the end user device. They are located in between the end user devices and connected between them through the cables.

The main function of the computer network devices is to forward the data to the correct destination based on the address that is send along with the data. The two main devices that accomplish this are the routers and the switches. The router forwards the data according to the IP address while the switch forwards the data according to the MAC address inside the data frame.

4. Rules: the rules are the protocols that used between the end user devices that organize the communication. The two popular protocols are the IP protocol and the TCP protocol. When the end user needs to send the data, it runs a conversation first with the other device according to a set of rules that prepares for the transmission. Each network uses its own protocols set up by the administrator of the network to manage the operations inside the network. Note that this element is a software element and is set up by software programs
