Can multiple computers be hardwired to a single computer?
no as this would increase the load on a single processor thereby causing reduced performance also different frequencies of other processors will not match the given proccssor
By choosing the switch Bandwidth like 100 Mbps, or 1000 Mbps you can make fast LAN.
What distinguishes the Transport layer from the Session layer?

A three way switch is a switch that is used in a lighting circuit that allows the light fixture to be turned on from three separate locations within the building. In electrical terminology this switch is also referred to as a SPST, Single Pole Single Throw switch. The switch has three individual terminals of which two are always connected. These switches are usually located at the far extremes of the circuit with an intermediate switch between them. This intermediate switch is referred to an a four way switch.
Can two pcs communicate to two different networks through a router without a default-gateway?
No, because without a default gateway configured the packet will never get to the router, and thus never get to the other network.
What is computer geographic scope?
Computer geographic scope is the coverage that computers have within a certain geographic area. It is also how far the computer along with its network can reach geographically. Local networks use dedicated data channels and consist of private branch exchanges and local area networks. Wide-area networks use telecommunication channels and also include value added networks.
What is the cable color coding in Toyota hilux?
www.installdr.com can help a little but it leaves a few wires out like what to connect to the pink with blue stripe wire or the light green wire the brown wire and the gray with black stripedont know what these do.
Dynamic Host configuration Protocol different IP address every time it connect to the network (How to work DHCP server):-
It Provide IP address in any system in the follwing four step :-
1) Dynamic Host Configuration protocol Lease Request.
2) Dynamic Host Configuration Protocol Lease Offer.
3) Dynamic Host Configuration Protocol Lease Selection.
4) Dynamic Host Configuration Protocol Lease knowlegment.
1) Dynamic Host Configuration Protocol Lease Request :- At first client prepare a packet and broadcast from searching the Dynamic host configuraiton protocol server.
2) Dynamic Host Configuration Protocol Lese Offer : Now the Dynamic host configuration protocol server select the internet protocol address from the scope the give the offer to the clients ,if more than one dhcp server if present in network than the dhcp server in which offer come enough first basic provide ip address.
APIPA(Automatic Private ip Addressing ) : In case DHCP server not ip addressing provide so this situation by APIPA ip address provide from clients side It range the IP address 169.254.0.1 to 169.255.254 in this case the client which broadcast massanger at first time will take specific IP from APIPA after this it always contect every five minutes to any Dynamic host configuration protocol server.
3) Dyniamic Host Configuration Protocol : When client take the offer then the Dynamic host configuration protocol server send the selected IP address from the client.
4) Dynamic Host Configuration Protocol : After giving the IP address given the server send massage Dynamic host configuration protocol client.
In most cases - true. Please review the following website on the About network for more specific information: http://compnetworking.about.com/od/basicnetworkingconcepts/a/network_types.htm
Why would you implement the DHCP?
By implementing DHCP, you would eliminate the need to set-up IP addresses manually.
DHCP (Dynamic Host Configuration Protocol) simplifies the management of IP address configuration by automating address configuration for network clients.
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.
Can you connect four switches to one Router?
Yes. Just connect one switch strait into the router. Then hook the other three switches into the first switch. -DJ Craig
What kind of cable would you use to connect an XBox to a router?
Standard Category 5 (Cat5) networking cable will do if the length is 100 meters or less. If it will be longer, but less than around 350 meters, you'll want Category 5e (Cat5e) cable. the Kat5 is all you need, I picked up a cable at biglots for 3 bucks and works great
How do you create VLAN step-by-step?
VLANs are created on Layer 2 switches to control broadcasts and enforce the use of a Layer 3 device for communications. Each VLAN is created in the local switch's database for use. If a VLAN is not known to a switch, that switch cannot transfer traffic across any of its ports for that VLAN. VLANs are created by number, and there are two ranges of usable VLAN numbers (normal range 1-1000 and extended range 1025-4096). When a VLAN is created, you can also give it certain attributes such as a VLAN name, VLAN type, and its operational state. To create a VLAN, use the following steps.
1) Configure VTP. VTP is a protocol used by Cisco switches to maintain a consistent database between switches for trunking purposes. VTP is not required to create VLANs; however, Cisco has set it up to act as a conduit for VLAN configuration between switches as a default to make administration of VLANs easier. Because of this, you must first either configure VTP with a domain name or disable VTP on the switch.
2) Create the VLAN. VLANs are created by number. The two ranges of VLANs are as follows: The standard range consists of VLANs 1 to 1000. The extended range consists of VLANs 1025 to 4096. Extended VLANs are currently supported only on switches running COS software version 6.1 or greater. When you create a VLAN, you have many options to consider. Many options are valid only for FDDI and Token Ring VLANs. Some of the items configured deal with options, such as private VLANs, which are discussed in other sections in this book. VLANs are created using the set vlan command for COS devices or with the vlan command in vlan database mode for IOS switches.
You need a router. The cable modem connects to the modem's uplink port and the switch can connect to any available port on the router. This wll enable any computers connected to either the router or the switch to access the internet.
Through a Wireless Access Point/Gateway/Router.
U can connect ur switch w/it's 5 wired pcs to the Router and ur wireless pcs to the router.
It means ensuring that each segment which the source sends arrives at the destination.
What information attribute is often of great value for networking equipment when DHCP is not used?
IP Address - For network devices (hardware only
Ip address-for network device
How do you identify a class of IP address and its corresponding subnet mask?
Look at the first octet value and check the corresponding range.
1-126 class A, subnet mask 255.0.0.0
128-191 class B, subnet mask 255.255.0.0
192-223 class C, subnet mask 255.255.255.0
172.17
255: 1111_1111
5: 0000_0101
1: 0000_0001
2: 0000_0010
Source IP address: 10.10.5.1
Subnet mask: 255.255.255.0
Subnet: 10.10.5.0 (host subnet)
Destination IP address: 10.10.5.2
Subnet mask: 255.255.255.0
Subnet: 10.10.5.0 (destination subnet)
The destination subnet address for 10.10.5.0 which is the same subnet as the host. Therefore, the packet stays in the LAN.
How would you troubleshoot the problem if you suspect that a router's LAN gateway is down?
You can use either or both ping/tracert.
What are the advantages of using CDMA for cellular network?
CDMA is Code-Division Multiple Access abbreviation, full known as Code Division Multiple Access, is a more advanced digital interface technology, which is characterized by a high frequency of utilization, mobile low power consumption, good quality voice calls. 2. Compared with GSM phones, CDMA mobile phone has the following advantages: First, the transmission power is extremely small, so conversation is not only less radiation, but also longer battery life mobile phones.
Second, the use of advanced soft-switching technology allows mobile phone is not GSM phones are dropped.
Third, better call quality, almost no noise when making a call, in the case of large background noise, you can also get a better call quality.
Fourth, a high put-through rate. As military interference from CDMA systems, and the signal occupy the entire band, almost an ordinary narrow-band modulation efficiency of seven times, so for the same bandwidth, CDMA system is the GSM system capacity of 4 to 5 times the extent of its mesh-plug a significant decrease in Therefore, uptake rates are much higher. 3. Ordinary GSM and analog mobile phone power 600 milliwatts under the general control, while the CDMA system, the maximum is only 200 mW transmit power, general power can be controlled at 0:00 call a few milliwatts, its radiation is negligible, there is no health adverse effects. As the base station and mobile transmit power reduction, so handset talk-time will be greatly extended battery life phone will also be extended to protect the environment played a role, it is called the "green phone."
