Computer Networking

One hazard that is related to fiber optic installation is that the light can burn the eyes. Another hazard is that glass splinters can penetrate the skin.

WAN usually costs more. Especially, there are recurring monthly costs, since you rent the services of an ISP. Note, however, that a LAN and a WAN serve different purposes; you can't simply replace a WAN with a LAN.

The most basic is "Ping".

The syntax is:
Ping remote host or ip address

i.e. ping www.google.com
or
ping 127.0.0.1

The File Transfer Protocol is a standard network protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client-server model architecture using separate control and data connections between the client and the server

Usually "network computer" refers to a computer whose primary function is to access the network and can't do much else on its own. Sometimes it is a dumb terminal with no processing power of its own, but more often it does have processing capabilities, but still less than a personal or business computer.

Network computers rarely exist outside large corporate networks, where they are generally assigned to very low-level employees with minimal computing needs.

Firstly,bus has no safety at all. And often had an accident. This risk can cause by driver or the circumstances at the road.

The main risk is that there will be a break in the cable connections somewhere, which causes the entire network to go down due to signal bounce.

Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".

Half-duplex - is the mode typically used in a walkie-talkie. Units usually broadcast and receive on the same frequency - so one party must wait until the other has finished transmitting before they can reply.

There are a couple other ways to refer to a MAC address. One could use the full name, media access control address, rather than the acronym. A MAC address could also be referred to a UAA, or universally administered address.

Primarily at layer 1 and 2. The frame adds this information for these layers.

Assuming IPv4 ICMP. Ping uses IP for transport. Ping in itself is an "Echo Request", which is a function of the ICMP protocol. The IP Packet will carry the ICMP protocol from end-to-end.

ICMP has a protocol number of 1, so the "Protocol" field in the IPv4 header will contain "1" as a reference to the ICMP payload.

For IPv6, ICMPv6 is used, and the transport will be IPv6.

In the fiber optics there are different types of losses; these are the bending loss, absorption loss, dispersion loss, and scattering losses. Bending losses is the loss which exists when an optical fiber undergoes bending, this includes macroscopic and microscopic bending. Absorption loss is the absorption of light energy resulting in dimming of light at the end of the fiber, this includes intrinsic and extrinsic absorption. Dispersion loss is the distortion of the signal as it travels along the fiber optic cable, this includes intermodal and intramodal dispersion. Scattering losses occurs due to microscopic variations in the material density, compositional fluctuations, structural homogeneities and manufacturing defects, this includes linear and non-linear scattering.

Network architectures are classified according to the way they are controlled and the distance between their nodes.

No, both sender and receiver have a private key and a public key. It works like this: if you encrypt something with one key, you need the other to decrypt it. You give everyone a copy of your public key. When they want to send you something encrypted, they use your public key to send it. Only your private key can decrypt it, so no one else can read it. You don't give out your private key.

Computer input devices are peripheral devices that provide data and control signals to the computer. The keyboard and mouse are the most important input devices.

in Class A addresses the first bit identifies the class. The next 7 bits identify the network and the rest are the IP's that belong to that network. However these networks are then broken down using subnets . Class A networks are not given to private clients or small private organisations. So if you want to know how many bits are there for identifying hosts in a Class A network, the answer is 32-8 = 24 bits. However if you mean how many bits are reserved for hosts in your private network space, that depends on your subnet and router. Most routers use NAT to allow multiple hosts to use a single external IP address. I hope this answers your question :)

Broadband does not have a set speed and 3 meg is a measurement of Internet speed. Broadband has a huge range in speed depending on your location and Internet Service Provider or ISP. If you are in a cabled network area it can be say 100meg or 10meg. If you get the broadband service down your phone line it can be 24meg 20 meg 8meg. The actual speed will vary from the advertised speed depending on whether you like far away from the exchange or not. It can even be as low as 0.1 meg or any other speed all the way up to 24meg. To see the speed in your area try putting your land line number into a broadband line check website, one of these can usually be found by searching "broadband line check" on Google.

No, an IP address is given to each internet provider, not each computer. For example, there could be five computers hooked up to the same network in which case they'd all have the same IP address.
