Computer Networking

ST is a bayonet-style connector that had the advantage over previous screw-on connectors because it could be mated with a "Single Twist" hence ST.

NIC is the abbreviation used when referring to a network card.

Optical Fibres are tiny cylindrical strands of glass that carry light rather than electrical energy. Fiber-optic cable is increasingly used for long-distance phone lines because it can carry large amounts of data, is not subject to crosstalk or electromagnetic noise, and cannot be tapped into without producing a noticeable drop in signal level.

* Glass and/or plastic cables connect to a light source and the light is carried from the source through the cable by a reflected inner lining. The diameter of the cables vary in milimeters and if bent sharply can break the integrity of the cable and diminish the light source. The cables can be cut to various lengths and the tips where the light comes out does not get hot. * Fiber Optic Fibers have been around for more then forty years, and since then they have become more cost effective and stronger. Plastic fibers are made with chemicals, the CORE is Polymethyl Methacrylate polymer (PMMA), and the CLAD is a thin layer of Fluorine polymer. The Core carries the light down the Fiber while the Clad is the reflective surface the light bounces off of! The diagram below shows what happens to light as it enters and travels through the fiber. Light enters through one end of the fiber and is "Reflected" to the other end, if the angle of the light is to great the light will not enter the fiber correctly and refraction will be lost. Skewed fiber is when the ends are not cut parallel to the 90-degree axis of the fiber. Light is also lost if the ends are not polished; to polish the ends of fiber you can use a 600 grit wet-dry sandpaper and finish with a 3m polishing film or a 1500 or greater sandpaper. The fiber has a 17% Clad which doesn't carry light, so the transmission of a one foot piece of fiber is in the area of 60-65%. * If light enters one end of a fiber, it will travel through the fiber with very low loss, even if the fiber is curved. The principle that makes this transmission of light work depends on the total of internal reflection. The light traveling inside the fiber center, or core, strikes the outside surface at an angle greater than the critical angle, so that all the light is reflected toward the inside of the fiber without loss. This allows the light to be transmitted over long distances by being reflected inward thousands of times. To keep the light from loosing its power and to avoid losses through the scattering of light by impurities on the surface of the fiber, the optical fiber core is covered or (clad) with a glass (or plastic) layer of a much lower refractive index; the reflections occur at the interface of the glass fiber and the cladding. * Tiny cylindrical strands of glass that carry light rather than electrical energy. Fiber-optic cable is increasingly used for long-distance phone lines because it can carry large amounts of data, is not subject to crosstalk or electromagnetic noise, and cannot be tapped into without producing a noticeable drop in signal level.

electrical problems are almost always traced to junctions, which a switch contains; also, a poorly made switch might poorly conduct, or be 'made to fail.' Also, the mechanical properties of a switch make it susceptible to mechanical failure. Understand that most of these problems are inherent to an individual switch; you won't find many weaknesses in a Mack truck switch, for instance.

Packet filtering is a form of network security that inspects each packet of data that passes through a computer network to determine whether it should be allowed through or not. This helps in controlling the flow of data and preventing unauthorized access or malicious content from entering the network.

You can create a table or spreadsheet to organize resources and their characteristics. List the resources in one column and their corresponding characteristics in the adjacent columns. This format allows you to easily view and compare the different resources and their attributes.

Both RFC 349 and RFC 1700 have an Assignment number and both have wide standard functions. They also offer applications that offer link, socket, port, and protocol.

a. memory

1. Packet copied by systems' CPU

2. Speed limited by memory bandwidth

b. bus

1. Datagram from input port memory to output port memory via a shared bus

2. Bus contention: switching speed limited by bus bandwidth

c. crossbar

1. Overcome bus bandwidth limitations

2. Banyan networks, other interconnection nets initially developed to connect processors in multiprocessor

3. Advanced design: fragmenting datagram into fixed length cells, switch cells through the fabric.

Active Directory organizes multiple domains hierarchically in a forest. A forest is the top-level structure in Active Directory that contains multiple domains. Each domain within a forest has its own security policies and trust relationships with other domains in the forest.

Generally speaking, UTP of Cat5, Cat5e, or Cat 6 is physically terminated with either an RJ-45 plug or RJ-45 jack.

The wiring pattern depends on whether you are using 568A or 568B as your cable standard.

1. The internal IP address is replaced with the PAT devices's IP address in the request packets source field.

2. A port number is assigned to the connection by the PAT device.

3.The packet is forwarded to the external network.

4. The packet's information is entered into the PAT device's translation table so that all packets sent from the same connection can be translated to that port number.

NIC stands for Network Interface Card. It is a hardware component that allows a computer to connect to a network, either wired or wireless, and communicate with other devices on the network.

Hi, Fiber Optics transmit signal using lights rather than electic current, so when signal passes though an optical fiber cable, it does not generate electric or magnetic field around it, and it is not affected by surrounding magnetic or electric fields Adv of optical fiber is that they are immune to noise, signal passes at lights speed, and no signal power is lost along the transmission line.

This is a description of twisted pair cable, which is commonly used in network and telephone wiring. The color-coding helps to identify the pairs and reduce crosstalk. The copper wires are insulated to prevent short-circuits and maintain signal integrity.

The major benefit of a switch over a hub is the increase in the amount of collision domains. This allows a switched network to benefit from full duplex transmissions, negating the need for CSMA/CD, and doubling the potential throughput for each network segment. Switches typically operate at layer 2 of the OSI model, using destination MAC addresses within the Ethernet frame to intelligently filter or forward packets.

Common connectors for fiber-optic networks are SC, ST, and LC. These three types of fiber-optic connectors are half-duplex, which allows data to flow in only one direction. Therefore, two cables are needed.

Yes, a flexible network of protein fibers called spongin provides structural support within a sponge's body. This network helps maintain the sponge's shape and allows for water flow and nutrient exchange through its pores.

You hold down the center buttons for about 3 seconds and "Voice Control" will show up keep holding down the button then your recent song will play. Then turn it on and off 2 times then go your app store and you see your app is installed.

The minimum size of an ICMP packet is 8 bytes, which includes the 8-byte ICMP header without any additional data. The maximum size of an ICMP packet is 65,535 bytes, which includes the maximum payload that can be carried within an IPv4 packet.

OpenVPN is often considered one of the strongest tunneling protocols due to its robust encryption and secure authentication methods. It is widely used for creating secure point-to-point or site-to-site connections over the internet.

It depends on the size of the venue and the type of music being played. A 100 watt amp could be sufficient for small to medium-sized venues, especially if it is mic'd through a PA system. For larger venues or louder genres of music, a more powerful amp may be needed.

Hi there,

If your charger is not working, There are few things might happen. Charger itself is bad, power cable may be bad if it is just replace power cable, or socket that connects to laptop may be bad, if so then you need to get it replaced.
we carry large inventory of chargers you can search your laptop model and search for it at www.nbbatt.com good luck
