What exactly does a modem do? and does it have memory?
Modems translate the signal coming on on the cable line into a format that your computer can use. They have enough memory to remember some basic settings.
What exactly is the sound a 56k modem makes?
What you’re probably referring to is the handshaking tone, like this.Those old modems operated on an analog communications network. There could be a lot of variability in the sound quality of analog lines.The handshaking was a way for the two modems (caller and receiver) go negotiate their communications speed. If the higher throughput didn’t work, it would drop to the next… until it fails or succeeds.
What is a modem exactly?
A modem is a network device that both modulates and demodulates analog carrier signals (called sine waves) for encoding and decoding digital information for processing. Modems accomplish both of these tasks simultaneously and, for this reason, the term modem is a combination of "modulate" and "demodulate."
How does a modem work and what does it do?
Modem stands for MODulator DEModulator and it was at one point the primary means of connecting users to the internet. Modems basically took an analog medium (noises over a phone line) and converted them to a digital signal (10101011) acting as an OSI layer 2 or Data Link layer in the computers connection to the Internet. (See OSI model)Modems connected users to their ISP (Internet Service Provider) via standard telephone lines. Transfer speeds ranged from 300 baud to 56,000 bits per second depending on where in the timeline the equipment was from, and the quality of the lines the users call routed through. The limitation of 56kbps was a major contributor to other technologies rapidly supplanting the modem as the standard connection method. Many users could do no better than 33.6kbps as they were restricted by the telco's equipment regardless of the modem's max speed. The term modem has an expanded definition today as any device that connects the user to the providers network seems to be called a modem (Cable modem; DSL modem; etc.) regardless of whether the device actually fits the definition of a modulator/demodulator. Many users unfamiliar with basic terminology refer to the PC case or tower as "the modem".
What exactly is IP address?
an ip address is a unique address for a networking device like a computer or router or modem. they are of two types private ip address and public ip address private ip address is for ur local network.public ip address is the internet ip address that is provided by your isp when u turn on your modem.when u r connected from modem->router->computer, the modem will create a private ip address and provide it to the router. now the router will create another private ip address and give it to the computer.the modem maps the internet ip address to the privaate ip address created by itself.the router maps the private ip address that is provided by the modem to the ip address created by itself and gives it to the computer.
What is WPS in modems?
Google is your friend, WPS (Wi-Fi Protected Setup) is a push button mechanism to add devices to a wireless network without having to program with a pre-shared key. That the AP in question is included with a modem doesn’t change what it does or why. What happens is that you push the WPS button on the AP and then on the client device, the AP generates a PIN, gives it to the client device, the client devices can then connect to the WiFi network, and the client then remembers that PIN for subsequent connections.Simple Questions: What is WPS (Wi-Fi Protected Setup)? | Digital Citizen
Why is a modem used?
It is used to enable computers to communicate with each other over telephone networks. The use of modem in modern computer networking is to Modulate and Demodulate the network signals. Modem helps to transmit data to computer using cable and telephone lines. It waves the signal into analog transform.Source: Google.
Do I need a router and a modem?
Router:A router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect.Using assigned numbers, the router keeps track of which computer made a request to the Internet in order to send responses back to that computer only.Modem:A modem is a hardware device that allows a computer to send and receive data over a telephone line or a cable or satellite connection.Modems are generally classified by the maximum amount of data they can send in a given unit of time, usually expressed in "bps"This is a small device that connects to your internet service provider (ISP) to tap into all that internet goodness. The connection is made via a cable (for cable or fiber internet) or phone line (DSL) from outside your house that plugs into the back of your modem. Your modem shares this connection with a computer or a router via an Ethernet cable.Do I need a modem?Without a modem your router will only allow you to connect to a LAN (local area network). The modem is your connection to the Internet.Well, a modem just connects to your isp so that you can connect to the internet. Something that is just a modem will likely only have a port for the phoneline and an ethernet port.Do I need a router?Picking a modem is only half the battle, because they typically provide connections for just a single, wired device. If you want to go wireless, you're going to need a router, which is a networking device that lets you share your modem's internet connection with all your devices. Routers connect to your modem via an Ethernet cable and pass that internet connection on to other devices in your house either via an additional Ethernet cable or wirelessly over a Wi-Fi network.if you have multiple devices to connect or want wifi you need a router to plug into the modem. A lot of the time the modem your isp gives you will have a cheap wifi router in it already.Concluison:A router is used to connect devices together to make a network. Called a LAN or Local Area Network.A modem is used to connect devices to the Internet. Called a WAN or Wide Area Network.Read more at https://zappedia.com/network-and-networking/
What does download speed mean, exactly?
Internet speeds are rated in megabits per second. 5 mbps = 5,000,000 bits every second Download speeds are typically rated in kilobytes per second. A kilobyte is 1024 bytes. There are 8 bits in 1 byte. So, let's convert your internet speed into kilobytes per second. Your internet speed is 5 megabits per second: 5,000,000 Divide by 8 to get the number of bytes per second 5,000,000 / 8 = 625,000 Then divide that number by 1024 to get the number of kilobytes: 625,000 / 1024 = 610.3515625 kilobytes per second So, about 610 KB/sec would be your theoretical maximum speed if you were getting the full 5mbps. So, if you're seeing 500 KB/sec downloads, then you're getting about 500/610 = ~82% of your rated download speed which is fairly decent. However, often times you'll never reach this speed due to many reasons. Overhead, noise on the line, lots of traffic on your neighborhood's node, etc. If you do an internet speed test (http://www.speedtest.net/) from a server located nearest you, that would be a better number to use to compare your download speeds to.
