mbps is greater than kbps....
Not so.
The prefix of "m" means "mili-" (1/1,000), for example "mm", "mg", "mW", "ml" etc. The prefix of "k" means "kilo-" (1,000 multiple), for example "km", "kg", "kW", "kV" etc.
Then a "mili-bit-per-second" is 1,000,000 times less than "kilo-bit-per-second", in other words mbps ie less than kbps. The question probably should be "Is Mbps greater than kbps?". If so, the prefix of "M" means "mega-" (1,000,000 multiple) and Mbps is greater than kbps.
How do you find words in a word search?
To create a word search puzzle with Microsoft Word you can type out all your letters then go to insert shapes and choose a line then put lines between the letters. Although it's easier to just use puzzles.com
What is tab split box in excel?
It enables you to split the window in Excel into separate panes. It is not in Excel 2013, but in earlier versions it is a very narrow item just above the scrollbar on the right of the screen. If you put the mouse over it, it changes into a pair of horizontal lines with an arrow pointing up and another pointing down, which you can then use to drag down and split the screen. There is also one at the right end of the bottom scrollbar.
Most network cards in consumer's personal computers can operate up to 100 Mbps or one hundred megabits per second or 12.51 MB per second. While that is fast, most ISPs(Internet Service Providers) only provide internet access at barely one-half of that speed around 50 Mbps or 6.1 MB per second on average. Check with the company you are subscribed with to see how fast or perform a speed test on you connection.
How does the modem send signal?
A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.
Fortunately, there is one standard interface for connecting external modems to computers called RS-232. Consequently, any external modem can be attached to any computer that has an RS-232 port, which almost all personal computers have. There are also modems that come as an expansion board that you can insert into a vacant expansion slot. These are sometimes called onboard or internal modems.
While the modem interfaces are standardized, a number of different protocols for formatting data to be transmitted over telephone lines exist. Some, like CCITT V.34, are official standards, while others have been developed by private companies. Most modems have built-in support for the more common protocols -- at slow data transmission speeds at least, most modems can communicate with each other. At high transmission speeds, however, the protocols are less standardized.
Aside from the transmission protocols that they support, the following characteristics distinguish one modem from another:
- bps : How fast the modem can transmit and receive data. At slow rates, modems are measured in terms of baud rates. The slowest rate is 300 baud (about 25 cps). At higher speeds, modems are measured in terms of bits per second (bps). The fastest modems run at 57,600 bps, although they can achieve even higher data transfer rates by compressing the data. Obviously, the faster the transmission rate, the faster you can send and receive data. Note, however, that you cannot receive data any faster than it is being sent. If, for example, the device sending data to your computer is sending it at 2,400 bps, you must receive it at 2,400 bps. It does not always pay, therefore, to have a very fast modem. In addition, some telephone lines are unable to transmit data reliably at very high rates.
- voice/data: Many modems support a switch to change between voice and data modes. In data mode, the modem acts like a regular modem. In voice mode, the modem acts like a regular telephone. Modems that support a voice/data switch have a built-in loudspeaker and microphone for voice communication.
- auto-answer : An auto-answer modem enables your computer to receive calls in your absence. This is only necessary if you are offering some type of computer service that people can call in to use.
- data compression : Some modems perform data compression, which enables them to send data at faster rates. However, the modem at the receiving end must be able to decompress the data using the same compression technique.
- flash memory : Some modems come with flash memory rather than conventional ROM, which means that the communications protocols can be easily updated if necessary.
- Fax capability: Most modern modems are fax modems, which means that they can send and receive faxes.
How do you access a computer connected to a DSL modem through the Internet?
Yes you can use DSL modem to connect to Internet, but you need to have a DSL connection (through a phone line) subscribed and activated with an internet service provider or a phone company which provides DSL internet access. As there are many forms of DSL technologies, you need to make sure that modem is compatible with the service provider network. Typically when you subscribe to a internet connection, the service provider provides their own modem to the customer. - Neeraj Sharma
Can you connect to routers to a cable modem?
Not directly. To create a local wireless ethernet network connected to a cable modem a Wireless Ethernet Router Box (WERB) would be required. It connects to the Cable Modem (CM) using an ethernet cable.
If all you want is to have a local wireless ethernet network, the WERB would do that for you and you won't need to use the 2-Wire DSL wireless modem router.
The 2-Wire DSL wireless modem router really does the same as CM + WERB but for connection of local computers and peripherals to a 2-Wire DSL ISP instead of to a cable ISP.
Normally a cable modem connects to an ISP's cable network on one side and, on the other side, to either a single computer or to an ethernet router which could be either of the hard-wired "local cable" type or a "local wireless" type. The ethernet router then connects to several local computers or peripheral devices such as printers, scanners, etc.
A DSL wireless modem router connects to an ISP's 2-wire copper telephone line on one side and, on the other side, via a local wireless ethernet to several local computers or other peripherals such as printers, scanners, etc., each of which must have a local wireless ethernet connectivity device. It is not clear from the question that you want to enable local computer users to connect reliably to either the ISP handled by the DSL wireless modem router or to the ISP handled by the cable modem. If that is what you want, then, if you are not already familiar with setting-up ethernet devices -- which may be the case as you asked this question here -- either get an ethernet router expert to help you or read the instructions that come with all modems and routers to find out what to do.
What are the requirements of getting internet connections?
There are many different type of internet conections, and each have different requirements.
Most internet can be set up down your BT telephone line, this includes Dial-up and broadband connections.
If you live in a cable area then you can get internet throught this as well as cable TV.
You must also have a computer, a modem (normally provided with internet bundle) and a few wires (also provided)
How do you split cable internet to get cable television?
Depending on your cable company, it may not be possible. If you are paying for cable tv service, then you should be able to use a splitter from radioshack or anywhere that sells them. Make sure you get a splitter that goes up to 1000mhz, or 1 ghz. The splitter has an in and at least 2 outs, maybe more depending on how many devices you want. Be aware that splitting cable signal cuts it in half and if you do not have enough signal for this, your internet may stop working. If you are not paying for tv service, most companies will put something called a hypass on the line. This allows only the frequencies that carry internet signal to pass through. If you do not have one of these installed on your line, than you should be able to get tv reception. Good luck!
How do you make my PC wireless?
If you mean a wireless network connection - you should buy a WiFi adapter (USB or PCI or PCI-e), install it in your computer and then set-up a new network connection.
If you mean wireless as no-cable-power - there is a problem. Desktop computer uses much more power than laptop and no battery can power it for a time longer than few minutes.

What services can you expect from cable television?
Cable television companies offer a horde of services to suit individual preferences. They offer local, national, and international programs and channels. Although each cable company has its own set of packages and services, they differ only slightly, and fall broadly under the same categories. These categories can be classified as:
-
Basic Cable Services: As the name implies, this is the most basic level of services. Basic services include all the off-air broadcast television channels as well as all the mandatory franchise related channels, and the government public and education channels. These also include the free to air channels. With almost all cable companies, it is necessary to subscribe to the basic service to be able to receive any of the other available services. Basic service programs can change at any time.
-
Second Tier Services: This level of service is the one that most people subscribe to as it offers most of the popular channels. It includes national super stations such as WGN as well as other programs such as the Sports channel
It looks like a small device with glowing light emitting diodes, (when turned on) and slots placed behind to have cables from the computer and from the phone line connected into it. It has an input for the power supply, also. Its shape is usually rectangular.
Would a modem be like a router?
1. They are not the same.
2. A modem is a device used to send information to and receive from another computer or network. Modem stands for MOdulator/DEModulator and is normally used to send over phone lines. There are other applications (like satellite links, etc).
3. A router does just what it says. It routes signals on a network. One in a home application is normally used to share one access point to the internet between multiple computers.
This is a bit of a simple answer but hopefully you get the idea!
What is a default gateway What happens if don't have one?
A Default gateway
is a node (a router) on a TCP/IP Network that serves as an access point
to another network. A default gateway is used by a host when the ip's
packet destination address belongs to someplace outside the local subnet.
Without a default gateway you will not be able to route packets out
of your LAN
Why won't Wireless router won't connect to modem?
There are many reasons. One of them is you are trying to connect to secured network without knowing the pass phrase. Also your network adapter might not be compatible with the network. Another thing is that you mac address can be on the black list of blocked mac addresses. It's possible that the router which you are trying to connect to is using so called white list and your mac is not on that list.
Roll over cable colour code for rj45 connector?
To know colour coding of cross cable we need to know some basic facts like where it is use and from where we can generate it.The answeres are crossover or we say cross cable is used for connecting similar devices like pc-pc or hub-hub etc,and we can generate it from the basic colour coding of 568a standard.But the question is how?as 568a standard is a standard for twisted pair but itscomes under the subcategory ofunshield twisted pair cable.so,lets come to the main ans,so here we go--
568a colour coding is
green=gr,white=w,orange=or,blue=bl and brown=br(short form)
1.gr/w
2.gr
3.or/w
4.bl
5.bl/w
6.or
7.br/w
8.br
As we can see above the colour coding of 568a cables{straight(use to connect dissimilar devices like pc-hub)}the basicof colour coding.we can generate the colour coding for cross cable from it-
straight cross
1.gr/w3-1 1-3 1.or/w
2.gr6-22-6 2.or
3.or/w 3.gr/w
4.bl4.bl
5.bl/w5.bl/w
6.or 6.gr
7.br/w 7.br/w
8.br 8.br
As we switch 3-1 that is put no.3 of straight in no.1 of cross(from left side)and cancel no.1 that is gr/w,so we get the combination of or/w in no.1 in cross.As we do the others that is
1-3,6-2 and 2-6(from left side)we get the combination for cross.If somebody wants to remember directly he can,but its the alternate method and from the basics.
Where should you place a router on a home network using 3 computers and broadband cable?
Attach the router to the Cable MODEM provided by your ISP.
Attach the computers to the router.
Your ISP and router provider should have supplied cds with installation wizards to make the connections happen automagically.
What cable type is needed for a hardwire internet connection?
Which cable type is needed for a hardwire internet connection?
Why is a modem necessary for connecting computers in networks?
Modems are a bit dated actually. Generally admins just use 'network cards' (NICs) nowadays. A network is a few computers all connected together...right. So if you want to plug your computer into that network.. where do you think the wire for the computer gets plugged into..??? The network card.
What is the difference between cloud computing and conventional computing?
Conventional Computing
- Hard Disk Storage and same physical location
- does not require internet or intranet to access files
- must use a compatible system to access files
Cloud Computing
- Data is stored in remote servers
- must be connected to the internet to access files
- any internet ready device with updated browsers view files
