Computer Networking

A router connects multiple computers together and transmits data to its correct destination on a network.

Ff:ff:ff:ff:ff:ff

it is very dificult to do that so i would sugest finding out the programs and softwares that you want and go download or by them yourself. or you have to go through a long and hard process of sending through the computer cables and that takes forever. so the other way is easier. :D

Switches store the MAC addresses in an internal database called MAC Address Table. The entries in that table can be addresses learned by the switch or that can be entered manually by the switch administrator. This table is analogy to a router's routing table, only a switch operates at layer 2 whereas the router operate at Layer 3.

Host computer is a central computer or server which connected all other devices within a network.

Computers listen to the network for clearance to send data.

The network layer or layer 3 is where you would expect to find routers or possibly layer 3 switches. The network layer is the point where different networks can converge. Routing tables held on layer 3 devices are the path out of the network. If you look at your ipconfig information with the /all switch you will see an address given for default gateway. This will point to the router that is aware of all other networks or sub networks you have access to. In the home this is usually the inside or private address of your DSL or cable modem.

I understand some bridges operate at layer 3 as well.

At layer 3 Ethernet frames are formed into packets in preparation for routing between networks or sub networks.

Because the OSI layer is as implied open there are many examples of software and hardware that can operate at the network layer but router would be the best answer most of the time.

Wireless standard A and Dual-Band N.

The Answer is ICMP - A core protocol in the TCP/IP suite that notifies the sender that something has gone wrong in the transmission process and that packets were not delivered. Page 177. Networks + Guide to Networks 5th edition.

Absolute bandwidth is the relative bandwidth of the signal (B) times the center frequency (f0).

For example , by increasing the center frequency, the relative bandwidth is unchanged, but the absolute bandwidth is increased due to increasing the center frequency.

I hope it is helpful :-)

The maximum speed Ethernet of mm fiber has a transmission speed of 100 Mbit/s. The Ethernet mm fiber increases the speed from 10 to 100 megabits per second.

Adavantage sof computes in the office

1.Reduction in the data loss.

2.Maintenance of the records more quickly,accurately and easily.

3. storage of large amount of data.

4. Data Mistakes can be easily solved just by one click.

5. Accessibility of internet is an added advantage. one can get large amount of information on internet.

Advantages of computer networks:

Share resources, such as data, printers and connections (like the internet).

Centralize data for economy and security.

data processing,data storage,data movement and control.

Dynamic Host Configuration Protocol (DHCP) A protocol that provides a means to dynamically allocate IP addresses to computers on a local area network. The system administrator assigns a range of IP addresses to DHCP and each client computer on the LAN has its TCP/IP software configured to request an IP address from the DHCP server. The request and grant process uses a lease concept with a controllable time period.

The network in the secondary building should also be star topology. It is the most common and very reliable. There will be twelve desktop computers in the building which should be connected to each other and the main building as well. So there should be Cat 6 cabling used in this building. The other networking equipment needed in the building is a wireless router which will help the mobility of the employees, a networking switch for all the workstations and the wall sockets into which the Ethernet cables will be plugged in. There will also be two sockets for the printers. There will be VoIP phones on the desks with the computers

The Internet is a global network of computers. Every computer that is connected to the Internet is considered a part of that network. This means even your home computer. It's all a matter of degrees, you connect to your ISP's network, then your ISP connects to a larger network and so on.

It's a network operating using the Ethernet protocols at speeds of 1,000,000,000 bits per second or higher.

One. RJ-45 is a specification for a certain style of connector.

There are several TYPES of RJ-45 connector and the differences in them are in regards to the types of cable to be used in them. Some examples are, "Stranded wire" to be used with stranded (more flexible) conductors, "Solid Conductor" to be used to terminate cables with a solid wire and "Universal" which may work on either.

The specific difference in them is in the spades that are designed to cut through the insulator and provide a mechanical connection with the conductor inside upon crimping. While the "Stranded" specific type has more of a flat blade design, the "Solid" specific spades are designed with three "fingers" which straddle the solid conductor on both sides and the Universal spade is somewhat of a hybrid between the two.

From my experiences, the only real problem arises when you try to use a stranded version RJ-45 on a solid conductor wire. When this is done, the solid spade simply skips off to one side of the solid conductor after it pierces the insulator. While this may very well be touching the connector and providing a connection at first, any flex or age leads to a very intermittent connection at best and you'll be troubleshooting this connection in very little time.

I've not had a problem using the other versions on the other types of cables: Universal on either or Solid spade on stranded wire.

Turn off for five minutes and then turn it back on

Application server is used to serve the logic of the business to the application with the help of different protocol whereas web server is used to handle HTTP requests.

An application server is a computer that stores application programs designed to be run, as services, from a client computer. Depending on the application design, a client computer can run or invoke the remote application via a web interface or by running a client program designed to work with the application program.

A web server is a program (or application program) that receives requests from Web Browsers and responds by sending data back to the browser where it is displayed as a web page.
