Computer Server (service provider)

The server computer is a computer that provides, provides and offers internet services to other computer customers (clients / users of the service) where the computer must have a high specification.

Computer Client / Workstation / Node
 The following are Computer Networking Tools Pictures and Explanations
Client computers (users of server services)

Client computers are user-service computers that the server provides and are managers of the data it retrieves and are usually more numerous than servers and the specifications may be smaller than the computer server

 HUB computer network tool and explanation
HUB (jar cable hook ingan)

HUB is a device used to connect network cables from any computer or other device. Usually HUB is used to assemble the star topology.

HUB is also a set of networks in which there are many ports to connect between computers to each other to form an interconnected network.

Some functions of the Hub:
  • As a network signal amplifier
  • As a liaison server computer and computer client
  • Can be used to connect computers far enough distance
Computer Network Device Tools And Images And Explanations – Hubs are used to form a simple network or with other words are only used to connect multiple computers in one IP group location. If there is a packet coming into one of the HUB ports then the packet will continue on another port on the same HUB and this will allow all connected computers in one HUB to know the contents of the package
Development can be done by connecting the next HUB uplink. This can happen because the HUB used only has port 16 plus 1. Therefore if we want to add network we must increase the number of HUB
Based on its management, HUB consists of two types:
  • Manageable HUB is a manageable HUB or manage in such a way as software.
  • Unmana-Geable HUB is the opposite of manageable HUB, where Unmanageable HUB is an unmanageable or manageable HUB and management must be performed manually.
A collection of HUBs that form a network is called by the term Shared Ethernet . For such networks, each user will only gain bandwidth speed. In other words the speed gained will be shared with other users and of course if the capacity of small bandwidth but the users much then the access will run slowly
 Repeater Computer Networking Tools With Images And Explanations
Repeater (Signal booster )
Networks that utilize bus type topologies will usually find devices similar to HUB and are generally called repeaters. The function of this repeater is only as a signal amplifier when the distance between the server and the client separately far. By utilizing this repeater then the transmitted data can be received well in accordance with its original strength.

 bridge Computer Networking Tools With Images And Explanations
Bridge (connector of computer network)
Bridge is a tool used to connect one network to another network with the condition to have a type of protocol where the result is a single logical network and can also be applied to networks with different physical media.

Computer Networking Device With Picture And Explanation – Here bridge serves to study the destination address through it and direct it to the destination. In addition, the bridge also serves to insulate the network and when the network traffic is intended full or busy then the network will be divided into two smaller parts.
Some advantages over the bridge are:
  • Can be used to connect the type Different networks such as Ethernet and Fast Ethernet
  • Can learn and record Ethernet addresses
  • Can perform selection of data transmission only required by bridge
  • Can determine the source and destination segment. If the segment is the same then the delivery will be stopped when the segment is different then the delivery to destination will proceed.
  • Can prevent the damaged message from spreading

  • We can only do the sending of data desired and required by the bridge [Bridge19659021] unable to determine the source and destination segement when the segment is the same.
 Router is a computer networking device along with its explanation
Router is the tool that has the ability to filter and manage data from one network (LAN) to another network (LAN) based on certain protocols and types of protocols in which it is intended to prevent data from being mixed with other data.
Routers can also be used to connect multiple networks such as LAN MAN and even WAN .

Indeed the router does not have the ability to learn the data but the router has the ability to be able to define the data flow from multiple networks. The router operates on the Network layer. Therefore, the router does not pay attention to the type of topology and access level, the process of work is not limited by certain media or protocol. If the bridge knows the final destination of the data then the router can only know the location of the next router.
Computer Network Tool Tool With Images And Explanations – Incoming data on the router will soon be determined the delivery path by checking the table router the. Here the task is to read only the packets sent from the previous router.
The router consists of two types:
  • Dedicted router is a special device produced by factories.
  • Router PC is a functional router when there is more from one network. Some other functions that can forward IP data packets and mempu operate programs to manage routing packages.

 Switch </span data-recalc-dims=
 Switch function of computer networking tools with images and explanations
Switch (has the same concept with HUB but is superior)
Regarding the Switch has been alluded to earlier, Switch is a tool of development rather than the concept of bridge tool in principle the same as HUB only Switch here is superior because the data will be sent to the destination will pass the selection process and transfer speed is higher. Switches have two basic architectural styles:
  • Cut-through has advantages in terms of speed. It is clearly visible when the packet arrives, the switch will only pay attention to the destination address and then send it.
  • Store and forward serves to receive and select the entire packet before being sent to destination, with this type of architecture allowing the switch to detect damage and prevent packet delivery not disturbing the network.
Another difference that causes the number of users switching to a switch is that a switch is not found whose name is bandwidth bandwidth sharing. That is why the switch is faster than HUB.
The advantage of using the switch
  • Performance, that means the switch here has the ability to select incoming data before it is sent to the destination address so that damage to data can be found immediately. 19659021] May prevent the transmission of damaged or damaged data packets. This prevention is intended to prevent damage to the network.
  • The use of cable is not excessive / efficient
Disadvantages of using switches
  • In terms of price, switches are slightly more expensive than HUB.
  • Switches here can only take advantage of straight cable. If we want to use a cross cable, we must first turn it into a straight cable.
 Modem Computer Networking Tools With Images And Its Explanation
Modem (demodulator modulator)
Modem is one tool designed to run at a predetermined speed (300, 1200, 2400, 4800 or 96000 bits per second and so on) where this speed will determine the speed rather than the transmission of the data itself. Sometimes we ask, the modem is an acronym of what? Modem is an acronym of Modulator Demodulator .

    LAN Card / NIC computer networking device with explanation ” width=”347″ height=”209″ />
    LAN Card / NIC slot (connecting computer with cable)
    NIC ( Network Interface Card ) is a network card in the form of electronic board which will be installed on every network computer. The function of the NIC or LAN Card is to connect or connect between computers with networks that utilize the wiring media. In other words the function of this network card is to connect the computer with cable. Another term closely related to this network card is the network adapter. The visible part of the physical appearance of this network card on a laptop or computer is a slot.
    Here are two types of slots on the motherboard:
    • ISA slot types are usually black or brown.
    • PCI slot type usually white.
    Network cable
    Network cable is a cable that serves as a medium of connection between one computer with another computer or the link between the computer with some other network.
    Types of cable that is currently widely used is:
    Twisted Pair Cable
     UTP cable is a function of computer network hardware along with pictures
    UTP and STP cable differences
    This type of cable consists of two types: Shielded (there is wrapping wrap) and unshielded (no wrapping sheath). Usually this type of cable using RJ-11 or RJ-45 type connector. For more details about these two types of cables we can understand the following description
    • Shielded Twisted Pair (STP)
      STP is one type of Twisted Pair Cable cable that is commonly used in some installation businesses. This type of cable is usually shrouded by wrapping. The STP cable is also used for the IBM Token-Ring data network and network. The packaging itself is capable of providing better protection against EMI interference. Some of the weaknesses of this type of STP cable such as if the high frequency, the balance will decrease and can cause crosstalk and noise signal. In addition, the price was fairly expensive.
    • Unshielded Twisted Pair (UTP)
      Computer networking tools – UTP cables are commonly used on LAN networks and telephone systems. UTP cable has 4 pairs of copper conductor color in which each pair is twisted. For this type of UTP cable itself there are 5 categories (Cat 1 with 1 MHz performance applied to the use of Voice, Mainframe and Dumb Terminal, Cat 2 with 4 MHz performance applied to the utilization of 4 MB Token Ring, Cat 3 with 10 MHz performance applied on 10 Mb Ethernet utilization, Cat 4 with 20 MHz performance applied to the utilization of 16 MB Token Ring, and last Cat 5 with 100 MHz performance applied to 100 MB Ethernet utilization). This category will typically support low-speed voice signals and high-speed LAN signals. The 5th category of UTP is recommended to be used for LAN installation and used in star topology (star topology). ” width=”613″ height=”245″ />
      Coaxial Cable
       Coaxial cable
      Coxial Cable
      Coaxial cable is the most widely used network cable even though its price is more expensive and its use is more difficult if compared with cable Twisted pair. These types of cables generally have bandwidth that is wide enough that can be used to communicate broadband. Thick Coaxial (Coaxial thick) is usually used for backbone cables on the Ethernet installation of the building. Thick Coaxial Cable is capable of reaching a distance of 500 m or even up to 2500 m equipped with repeater.
      Thin coaxial / coaxial thin (10 Base 2) is the right type of coaxial cable if used at home or office that uses 2 to 3 computers . This type of cable is similar to a TV antenna cable. For the price is fairly affordable and the installation is quite easy. Cable type utilizes BNC / T type connector. This type of cable is usually used in a series of bus topologies.
      Computer Networking Device With Picture And Explanation – Parts of the coaxial cable that is the presence of copper conductor, the coat of the wrapper layer in the form of ground wire and the existence of most layers
      Here are some types of LAN Ethernet Protocols developed by using coaxial cable.
      • 10Base5 / Thicknet Cable is a Coaxial cable of type RG / U-8, where this cable is the original Ethernet cable and is now not used again on a modern LAN network.
      • 10Base2 / Cable "Thinnet" is a type RG / U-58 coaxial cable smaller diameter Thicknet and indeed this cable is made as the development and substitution of the role of thicnet other than that please note that this cable has started abandoned its users, although still utilized by a very small LAN network.
      Fiber Optic (F / O)
       computer networking tools
      Fiber optic cable
      Fiber Optics is one of the high quality cables usually used by large companies only. Components alone consist of optical glas in the middle found filament glas (core), around it there are layers of cladding, buffer coating, reinforcing material and outer protector. Typically, Information will be transmitted by utilizing light waves that convert electrical signals into light waves. Transmitter / modifier sinya commonly used is a LED or Laser. | Computer network tools
      Some advantages over the use of this type of cable such as large bandwidth capacity (Gbps), capable of transmitting data from 2-60 KM, able to withstand the influence of electromagnetic interference, the speed can reach more 100 Mbps and not affected by environmental conditions
      While the main weakness lies in the relatively expensive price and difficult installation process.

       Connector </span data-recalc-dims=
       connectors function Computer Network Tools With Images And Explanations
      Kinds of connectors (connecting cables with network adapters) [19659000] Computer networking tools – The connector is one of the tools can connect cables with network adapter (slot) on NIC / LAN Card. The cable connectors typically have to be adapted to the type or type of cables as follows:
      • UTP / STP cable paired with RJ-45 type connector
      • Coaxial cable paired with BNC / T connector
      • Fiber Optic Cable paired with connectors ST.
