The Internet is formed by networks throughout the world interconnecting and passing on data to each other. Routers make the Internet work by forwarding data using a unified addressing system. They can send information to anywhere in the world as long as that location has an IP address.
Routers vary inside to large expensive machines for commercial applications to small wireless boxes for the home electronics market. A router combines dedicated hardware and specialist software to achieve its task. To be effective, a router needs to be connected to at least two separate networks because its main task is to forward data from one network to another.
Look at the following figure, it directly display the relationship between computers and router
What is Router Used for?
Routers rely on the Internet Protocol to provide a common addressing system. The protocol defines an address structure which is universally implemented and is enforced by one controlling authority in each country. The IP address of any computer contactable over the Internet has to be unique. The computer sending information over the Internet has to package that data into a packet. The data packet contains a header which includes the IP address of the destination computer. Routers read this address and then forward the packet in the direction of its destination.
A router prepares for its work by compiling a list of possible routes to a particular destination. The format of the table does not require that every IP address is listed. They can be noted in groups. When a router is first installed it contacts its neighboring routers. These are the routers to which it is immediately connected. Each of these neighbors send their routing tables to the new router which then compiles its own routing table. Routers regularly exchange their routing tables and so information about routes held on one router eventually ripples through to all routers in the world.
The routing table contains several different paths to the same destination. The router uses an algorithm to rank these alternatives. There are many different routing algorithms in the world, but they generally all rely on the direction and the distance travelled to reach the target. The distance is often recorded as the number of links the route crosses. The direction tells the router which of its immediate neighbors starts that route.
Although the routing table contains alternative routes it does not list the routers in the path of that route, only the first router in the chain. The next router receiving the data packet then makes a calculation to decide which of its neighbors will receive the packet next, and so on. This distributed decision making allows routes to be switched in case of broken connections further down the line of which the originating router is unaware.
How to connect a router to computers
1. Ensure that both computers have a LAN (or an Ethernet) card allowing the sharing of files and peripherals. Though all new computers and laptops are equipped with such cards, you may need to buy and attach LAN cards for older models. (A network card is a devised either installed inside a desktop computer or a card that slides into a laptop. A router is the piece that will allow you to receive wireless internet and networking from the devise with the network card installed.)
2. Connect the cable from your Internet Service Provider (ISP) to the Internet port of your router. Note that if you have an ADSL connection, your input cable would be a telephone line that needs to be inserted into the ADSL port of the router. For all other connections, you would have a thicker cable known as CAT5 (or CAT6).
3. Take two Ethernet cables and plug them into the Ethernet ports of the router. Note that you will require a router with at least two Ethernet ports to share Internet on two computers. Plug the other end of each of the cables into the Ethernet port of the computers. If you have a router with a single Ethernet port, buy a network switch or hub and connect the router with it (using the Ethernet cable). In turn, the switch (or hub) that includes at least two Ethernet ports will have to be connected to the computers. (More info of switch, hub and router you can visit “Identifying What is Router, Switch and Hub”)
4. Switch on the router and the computers.
5. Configure the router by referring to its user manual. The configuration process defers depending on the type and brand of the router. Once configured, you should be able to access Internet on both computers.
The process of configuring a Cisco brand router involves the invoking of the User, Privilege, Configuration, Interface, and Line modes. These various modes are utilized to allow the definition of information relative to the password, hostname, IP address along with the subnet mask, clock rate, and line configurations that will dictate the behavior of the router device. Prior to powering up the router to undertake its configuration, it is necessary to first set up a terminal emulation application to 9600 baud with eight data bits, no parity and single bit stop. This process will also be used to define the type of protocol that will be implemented across the network which will be supported by the router that will be connected to the computer system’s serial port.
- Cisco router
- Ethernet cable
- terminal emulator utility like HyperTerminal
The initial steps to the configuration process after setting up the terminal emulation program is to power up the Cisco router and wait for the message prompt to be displayed.
To implement basic configuration, type at the command prompt the text 'Enter Privilege Mode' followed by the 'Router > enable' command.
When the cursor appears; type the 'Enter Configuration Mode' and the Router# configuration terminal command.
In order to implement password protection when accessing Privilege Mode, the 'Router(config)# enable password p@ssw0rd' and the 'Router(config)#enable secret s3cr3t' commands must be issued.
The 'Router(config)#hostname myrouter1 [Set the hostname to myrouter1]' instruction provides the user with a way of defining the Hostname or the Router Name that will be broadcasted across the network.
The commands to configure the Ethernet port consists of the 'myrouter1(config)# inte f0/0 [Enter Ethernet Interface Mode ( f0/0 for interface1, f0/1 for interface 2)]', 'myrouter1(config-if)# ip add 192.168.0.1 255.255.255.0 [Set IP address and subnet mask]', and 'myrouter1(config-if)#no shut [Active the port]' commands. These commands will allow the smooth flow of network traffic on the defined communication portals.
Configuration of the Serial Port makes use of the 'myrouter1(config-if)#inte s 0/0/0 [Enter Serial Interface Mode]', 'myrouter1(config-if)#ip add 192.168.20.1 255.255.255.0 [Set IP address and subnet mask]', and 'myrouter1(config-if)#no shut [Active the port]' commands.
It is also necessary to set the bandwidth that will be used by the router. This is commonly done by using the 'myrouter1(config-if)#clock rate 1000000 [Set the bandwidth to 1Gig]' and 'myrouter1(config-if)#exit' commands.
The Secure Console is defined by using the 'myrouter1(config)#line con 0', 'myrouter1(config-line)#password c0ns0l3', 'myrouter1(config-line)#login', and 'myrouter1(config-line)#exit' commands. These instructions will configure the access credentials that will be used to bring up this utility.
The auxiliary password that will be used to connect any modem device to the router hardware via the remote connection console may be done by using the 'myrouter1(config)#line aux0', 'myrouter1(config-line)#password auXo', 'myrouter1(config-line)#login', and 'myrouter1(config-line)#exit' instructions.
Securing the login process via SSH or Telnet processes is done by using Virtual Terminal Password. The commands 'myrouter1(config)#line vty 0 4', 'myrouter1(config-line)#password v1rtu@1', 'myrouter1(config-line)#login', 'myrouter1(config-line)#exit', and 'myrouter1(config)#exit' are executed within the Secure VTY line utility.
To finish the configuration process, the settings must be saved either by using the 'myrouter1#wr me' or 'myrouter1#copy run start' commands.
Cisco switches are network devices used on data networks to facilitate data transport. For a Cisco switch to be integrated into a network, it must be enabled before custom network configurations can be made. To enable a switch for network use, the switch will need to be named and secured with a privilege execution mode and console password.
Things You'll Need
Cisco Catalyst 2960 switch or other Cisco switch capable of IOS command line configuration (Cisco 2940, 2950, 2955 and others), Computer monitor
How to Enable Cisco Switches
1. Start the Cisco switch. Be sure that your monitor terminal is interactive with the switch so that you will be able to see the Cisco IOS command-line interface appear on start-up and configure the switch. Once started, the "Switch>" prompt will appear in the command-line interface.
2. Configure the switch with the host name network1switch. At the "Switch>" prompt in the IOS command line, type "enable," then press "Enter." The "Switch" prompt will appear. Type "#config terminal" and press "Enter." The "Switch (config)" prompt will appear. Type "#hostname network1switch" and press "Enter." The switch is now named "network1switch" and the next prompt will now read "network1switch (config)."
3. Set the privilege execution (exec) mode password to 123catalyst. At the "network1switch (config)" prompt, type "# enable password 123catalyst" and press "Enter." The privilege exec mode password is now 123catalyst. The next prompt will read "network1switch (config)."
4. Set the console password to 123cisco. At the "network1switch (config)" prompt, type "#line console 0" and press "Enter." The "network1switch (config-line)" prompt will appear. Type "#password 123cisco" and press "Enter." The console password is now set to 123cisco and the next prompt will read "network1switch (config-line)."
5. Configure the console line to require a password at log in. At the "network1switch (config-line)" type "#login" and press "Enter." The switch console line will now require a password at log in. The next prompt will be "network1switch (config-line)."
6. End the command-line configuration session. At the "network1switch (config-line)" prompt, type "#end" and press "Enter." The command-line interface session will now end. The new Cisco switch is now named network1switch with a privilege exec mode password of 123catalyst. This switch is further secured by requiring a console password of 123cisco at log in. This switch is now ready for further interface configuration and customization for your network.
Many Cisco switches require users to use the Cisco IOS command-line interface for device configuration. Familiarity and confidence with working in a command-line environment will enhance an administrator's ability and productivity when configuring many Cisco network devices.
Perform these steps in order to recover your password:
1. Either switch off or shut down the router.
2. Remove the compact flash that is on the rear of the router. This image shows the rear of the Cisco 2951 router:
For more information, refer to Back Panel Slots and Connectors on the Cisco 2921 and 2951 Routers.
3. Switch on the router.
4. Once the Cisco router is on Rommon mode, reinsert the compact flash.
5. Type confreg 0x2142 at the rommon 1> prompt in order to boot from Flash.
This step bypasses the startup configuration where the passwords are stored.
6. Type reset at the rommon 2> prompt.
The router reboots, but ignores the saved configuration.
7. Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.
8. Type enable at the Router> prompt.
You are in enable mode and should see the Router# prompt.
9. Type configure memory or copy startup-config running-config in order to copy the nonvolatile RAM (NVRAM) into memory.
Warning: Do not enter copy running-config startup-config or write. These commands erase your startup configuration.
10. Issue the show running-config command.
The show running-config command shows the configuration of the router. In this configuration, the shutdown command appears under all interfaces, which indicates all interfaces are currently shut down. In addition, the passwords (enable password, enable secret, vty, and console passwords) are in either an encrypted or unencrypted format. You can reuse unencrypted passwords. You must change encrypted passwords to a new password.
11. Type configure terminal.
The hostname(config)# prompt appears.
12. Type enable secret <password> in order to change the enable secret password. For example:
13. hostname(config)#enable secret cisco
14. Issue the no shutdown command on every interface that you use.
If you issue a show ip interface brief command, every interface that you want to use should display up up.
15. Type config-register <configuration_register_setting> . Where <configuration_register_setting> is either the value you recorded in step 2 or 0x2102 . For example:
16. hostname(config)#config-register 0x2102
17. Press Ctrl-z or end in order to leave the configuration mode.
The hostname# prompt appears.
18. Type write memory or copy running-config startup-config in order to commit the changes.

Computer networking devices are units that mediate data in a computer network. Computer networking devices are also called network equipment, Intermediate Systems (IS) or InterWorking Unit (IWU). Units which are the last receiver or generate data are called hosts or data terminal equipment.
The Internet has truly revolutionized the way we communicate. If you actually think about it, the Internet is computer networking at the highest scale of complexity. It’s a continuous link of connected computers that spreads worldwide. How is data transfer and the implementation of networking protocols made possible in this colossal network? It is made possible because of networking devices that regulate data traffic over the whole network, providing connectivity and control. The network design is based on the OSI (Open Systems Interconnection) model. Router, switch, hub and bridge are networking devices that act as mediators at various levels of this networking model.
What are the differences in the design and functioning of these networking devices: router, switch, hub and bridge?
Every one of these network devices which we compare in the following is a part of every Large Area Network (LAN), Wide Area Network (WAN) or small private networks. They integrate and connect the network at various levels, while providing control over data flow.
The main differences in functionality of Router, Switch, Hub and Bridge
A computer network connected to the Internet is designed to be a self-regulating network that can guarantee the transmission of data to right destinations and regulate overall data transfer. The network can be primarily divided into two types of devices which are terminals (connected computers) and control elements or connecting devices. The role router, switch, hub and bridge play in a computing network determines their basic functionality and difference.
Two or more computing networks are connected together by a router. It is charged with the responsibility of controlling the inter network data traffic. They are highly intelligent devices with embedded software that are used to control the flow of data packets across diverse networks.
A network switch is charged with the job of connecting smaller segments of a single network into a connected whole. They are extensively used in Ethernet local area networks.
A hub connects various Ethernet devices to integrate them into a whole network segment. It is one of the most basic hardware devices that connect two or more Ethernet terminals in a network.
A network bridge is nothing more than a type of switch. While a switch has multiple connection ports, a bridge has a single connection port. In the next section, let us have a look at the features of each one of these devices in more detail.
Referring to OSI model layers, a router is functional on the network layer of the OSI model, which is also known as level 3. They integrate logical subnet together and their operation is made possible by inbuilt operating systems. They are designed to calculate the best possible path for transmission of data packets between networks. The basis for routing of data through a router is the use of Internet protocol addresses. You might want to check out the OSI model diagram to understand the functions of these devices better.
Network switches are functional on the layer 2 of the OSI model. This layer is often referred to as the data link layer. Network switches transfer data across a network segment using MAC addresses for reference.
A hub operates only at layer 1 level of OSI model, which is the physical layer. Integrating Ethernet terminals together is its only function and it is a passive device used for data transfer. A bridge is just a type of network switch that connects two network segments together. Like switches, they too operate at the data link layer.
All these networking devices provide connectivity and help regulate Internet traffic through local and global Internet networks. Tips of identifying what are main networking hardware help you know the role and function of router, switch, hub and bridge in a network. So which network equipment you select depends on what you need in your home network or business network.
Common basic networking devices:
Router: a specialized network device that determines the next network point to which it can forward a data packet towards the destination of the packet. Unlike a gateway, it cannot interface different protocols. Works on OSI layer 3.
Bridge: a device that connects multiple network segments along the data link layer. Works on OSI layer 2.
Switch: a device that allocates traffic from one network segment to certain lines (intended destination(s)) which connect the segment to another network segment. So unlike a hub a switch splits the network traffic and sends it to different destinations rather than to all systems on the network. Works on OSI layer 2.
Hub: connects multiple Ethernet segments together making them act as a single segment. When using a hub, every attached all the objects, compared to switches, which provide a dedicated connection between individual nodes. Works on OSI layer 1.
Repeater: device to amplify or regenerate digital signals received while sending them from one part of a network into another. Works on OSI layer 1.
Some hybrid network devices:
Multilayer Switch: a switch which, in addition to switching on OSI layer 2, provides functionality at higher protocol layers.
Protocol Converter: a hardware device that converts between two different types of transmissions, such as asynchronous and synchronous transmissions.
Bridge Router (B router): CombineS router and bridge functionality and are therefore working on OSI layers 2 and 3.
Hardware or software components that typically sit on the connection point of different networks, e.g. between an internal network and an external network:
Proxy: computer network service which allows clients to make indirect network connections to other network services
Firewall: a piece of hardware or software put on the network to prevent some communications forbidden by the network policy
Network Address Translator: network service provide as hardware or software that converts internal to external network addresses and vice versa
Other hardware for establishing networks or dial-up connections:
Multiplexer: device that combines several electrical signals into a single signal
Network Card: a piece of computer hardware to allow the attached computer to communicate by network
Modem: device that modulates an analog "carrier" signal (such as sound), to encode digital information, and that also demodulates such a carrier signal to decode the transmitted information, as a computer communicating with another computer over the telephone network
ISDN terminal adapter (TA): a specialized gateway for ISDN
Line Driver: a device to increase transmission distance by amplifying the signal. Base-band networks only.
Dell Inc.’s deal on Wednesday to buy Force10 Networks will give the world's second-largest computer maker inroads into Cisco Systems Inc.’s turf -- networking.
Force10 is a data center networking company that makes Ethernet switchers and routers, and focuses on serving booming social media companies like Facebook and Zynga as well as giants like Google Inc.
With the acquisition of Force10 at an undisclosed price, Dell is creating a more serious competitor to Cisco, adding to the networking giant's troubles.
Cisco is already facing intense competition from smaller networking companies like Juniper Networks Inc., Check Point Software Technologies, F5 Networks Inc. and Riverbed Technology Inc.
Cisco's switching business has seen sales fall in recent quarters, and analysts have argued the company has stretched itself too thin by making several large acquisitions in the consumer market, causing it to lose focus of its core switching and routing businesses.
Force10, which generated about $50 million in revenue in the first quarter of 2011, has an edge over competitors.
Cisco, Juniper and Brocade Communications Systems Inc. all provide switching and routing technology, although very few like Force10 have the technological capability that creates the backbone of the major data centers, sources said.
The deal also means that Dell is no longer interested in buying networking equipment supplier Brocade, whose market capitalization is $2.8 billion, sources said. Dell was reported to be eyeing Brocade as well.
Over the past three years Dell has expanded its enterprise portfolio through acquisitions to include server and storage services.
In May, Dave Johnson, Dell's senior vice president of corporate strategy, told Reuters that it will continue to seek companies with valuations in the $1 billion to $5 billion range.
Dell was advised by Evercore Partners on the Force10 deal. The transaction was the first for technology investment banker Eric Mandl at his new firm. Tor Braham, head of technology M&A at Deutsche Bank, led the deal for Force10.
SALE VERSUS IPO
Force10's decision to sell to Dell is the latest in a string of private technology companies in the sector that are opting to sell rather than go public, as tech giants looking to build a broader suite of services swoop in with rich offers.
Force10 had filed its initial public offering with the Securities and Exchange Commission last year.
But in 2011, the company started discussions with a few interested parties over a sale, one source said.
Other companies that have in recent months opted to sell rather than go public include Internet video conferencing service Skype, which sold to Microsoft Corp for $8.5 billion, and Web hosting company Go Daddy which sold itself to a private equity consortium led by KKR and Silver Lake this month for $2.25 billion.
To serve small and medium-sized businesses better and meet higher networking requirement, Cisco new wireless-enabled integrated services routers give businesses greater power to deploy services "on demand" as business needs dictate-while reducing overall operating costs. These platforms enable delivery of high-definition collaboration at the branch office and provide secure transition to the next generation of cloud and virtualized network services.

Cisco announced its Connected Stadium Wi-Fi initiative which includes an enhanced access point, improved antennas and services to further its leadership in networking and telecommunications.
Cisco Connected Stadium Wi-Fi provides high-capacity; blanket Wi-Fi coverage on a converged and customizable network for all persons in attendance at the event, including employees, back office and press operations. It is generally available in stadiums, arenas and other congested environments. Fans are demanding a new set of services and with this access to Wi-Fi you'll be able to see app providers and physical service providers deliver a new experience in live venues. Other uses of the technology include the ability for fans to watch video highlights, view stadium information and allows operators and venue owners the use of advertising on the network for additional revenue.
Core to the solution is Cisco’s first purpose-built access point, the Aironet 3500p, an evolution of the Aironet 3500 that was announced last year, and designed to meet the performance and aesthetic needs of high-density environments. This new access point optimizes performance through a high-density directional antenna and special configuration that allows precise focus of the wireless airwaves into a concentrated area. Each venue is different, and Cisco said that each system of access points will need to be tailored depending on the size and structure of the venue. Cisco retails each access point at $1,500 and said that a stadium which seats 50,000 fans would need around 350 access points for full coverage.
With the increase of fans using smartphones and tablets to share daily info, experience and work, the Wi-Fi Coverage in the Sports Stadium and Entertainment Venues is expanded, which is benefiting people who like to work or share things in public, such as Starbucks, bars, clubs, sports stadiums. And now Cisco Connected Stadium Wi-Fi is delivering rich and interactive experiences pervasively to fans anytime, anywhere.
Notes: More details of Cisco Aironet 3500 Series you can see Cisco’s official website.
