1. What is a modem, and how does it help us to make the leap from a simple network to the Internet?
A modem is a piece of device converts computer data into telephone readable data so that they can be transferable through the telephone lines and then converts the telephone readable data back to computer data.
The modem helps us make a leap from a simple network to an internet by converting computer data from the router into data that are transferable through the telephone lines. These data are transferred through the telephone line by the ISP across the globe, and converted back to computer data by the modem.
2. What is the difference between a Modem and a Router?
The router connects more than one computers while the modem connects the router to the telephone lines or signals.
3. What is the job of an ISP?
The job of the ISP is to send information across the globe through the fiber optic cable. An ISP receives data through the telephone lines or signals from the modem and then transfers them to another ISP through the fiber optic cable buried under the ocean.
4. What is the “backbone” of the internet that helps to connect ISPs across continents
It is the fiber optic cables buried under the ocean.
1. What is a modem and how does it help us to make the leap from a simple network to the internet?
And: A modem is a device that does 2 basic functions which are:
Modulation & Demodulation- Converting Digital information to analog signal from a source and is transported to the destination which is later converted to digital signal and becomes readable to the receiver.
B. With the help of a modem conversion from what we understand digital information to what is transportable which is analog signal & vice versa. When it gets to the intended recipient it would have been impossible if it were not so to be able to connect to the internet.
2. What is the difference between a modem and a router?
Modem- It helps to convert digital signal to analog signal & vice versa
Router- It helps to ensure that the message leaving a source at point A get to point B; the destination without getting to any unintended recipient.
3. What is the Job of an ISP?
The job of an ISP is to ensure that all computers on a network linked via routers can communicate globally irregardless of distance or location.
4. What is the “backbone” of the internet that helps to connect ISP across continents?
Fibre optics cable linked underground across the sea of continents to enable communication possible across continent seamlessly.
1. What is a modem, and how does it help us to make the leap from a simple network to the Internet?
– A modem is a network device that enables a computer to transfer data from telephone lines to computers and from computers to the telephone lines.
– The modem acts as a bridge between the ISP’s network and the home network. it converts the signal from the provider into a form that the devices can understand and use. Without a properly functioning modem, it won’t be able to connect to the internet at all, even if a router is set up.
2. What is the difference between a Modem and a Router? – A modem which stands for “modulator-demodulator”, is a device connecting your home to the internet service provider (ISP) through a physical connection. While a Router is a device that creates a local area network.Router connect to the modem and then to the devices such as computers, laptops, smartphones and tablets.
3. What is the job of an ISP? – Just as you have said, the ISP makes it possible for customers to access the internet while also providing additional services such as web hosting, email etc.
4. What is the “backbone” of the internet that helps to connect ISPs across continents? – The connections of one ISP to another ISP is what form the “backbone” of the internet across the continents of the world.
(1) A modern is a device or program that enables a computer to transmit data over telephone or cable lines. It helps us by turning electrical signals into digital signal that goes into the router then into our phone.
(2)our computers connect to the router and routers connect to the modem to connect our phones to our network provider .
(3) The job of the ISP( internet service provider) is to manages some special routers that are linked together that can also access other ISP. The ISP carries messages from our network to the destination network.
(4) connection of one ISP to another ISP is what form the backbone of the internet. This comprises of all the Fibre cables laid underground through seas across continents.
(1) A modem is like a translator for a computer .When we want to send or receive information over the internet,the computer speaks a language called digital data.However , the internet speaks a different language called analog signals .The modem takes the digital data from the computer ,translates it into analog signals so it can travel over the internet,and then translates the analog signals back into digital data when it reaches its destination.In this way ,the modem helps the computer communicate with the internet,allowing us to access websites ,send emails and do many things online .
(2)A modem brings the internet into our home whilst the router allows all our devices to connect to and use that internet connection.
(3)An ISP is a company that provides access to the internet.ISPs enable customers to connect to the internet through various means ,such as dial-up , broadband or fiber optic connections .The role of an ISP is to provide customers with the means to access and use the internet, ensuring that they have reliable and accessible connectivity to the online world
.(4) It’s made up of really fast and strong fibre optic cables that carry information between countries and continents .These fibre optic cables are buried at the bottom of the ocean .Just like how roads connect cities ,the internet backbone connects the ISPs ,allowing information to travel quickly and smoothly all around the world .
1. A modem is a device that enables computers to communicate over communication lines, such as telephone or cable. It converts digital data from a computer into analog signals for transmission and then back into digital data for the receiving computer.
A modem bridges the gap between a simple network and the Internet by enabling data transmission over long distances and various communication lines. It links local networks to the wider internet infrastructure, allowing devices to access the internet and communicate worldwide.
2. A modem connects to the ISP to provide internet access, while a router distributes that internet connection to multiple devices and manages local network traffic.
3. An ISP is a company that manages special routers that are linked together that can also access other ISP routers . The ISP transmit messages from one network to the destination network.
4. The backbone of the internet is the high-capacity network infrastructure that connects ISPs across continents which facilitating global communication and data exchange.
1. What is a modem?
– A modem (modulator-demodulator) is a device that converts digital data from a computer or network into analog signals that can be transmitted over traditional phone lines, cable lines, or satellite connections. It also converts incoming analog signals back into digital data that the computer can understand.
How does a modem help us to make the leap from a simple network to the Internet?
– A simple network, like a local area network (LAN), connects computers within a limited area, such as a home or office. However, to connect this local network to the wider internet, a modem is required.
– The modem acts as a bridge between your local network and your Internet Service Provider (ISP). It modulates outgoing digital data into analog signals for transmission over phone or cable lines, and demodulates incoming analog signals back into digital data.
– This conversion allows your local network to communicate with the broader internet, enabling access to websites, online services, and other computers worldwide.
2. Difference between a Modem and a Router?
The modem is responsible for sending and receiving signals from the ISP, while the router disperses the signal to devices on the network.
3. What is the job of an ISP?
– Provide Internet Access: ISPs offer internet connectivity to homes, businesses, and other organizations. They supply the necessary infrastructure (like cables, satellites, and wireless connections) to connect users to the internet.
– Assign IP Addresses: ISPs assign IP addresses to devices on their network, enabling them to communicate with other devices on the internet.
– Manage Network Traffic: ISPs manage the flow of data between users and the internet, ensuring efficient and reliable connectivity.
– Offer Additional Services: Many ISPs also provide additional services such as email hosting, web hosting, and television services.
4. What is the “backbone” of the internet that helps to connect ISPs across continents?
The backbone of the internet consists of a network of high-capacity, high-speed data transmission lines that interconnect different regions, countries, and continents. These lines are typically fiber-optic cables.
– They handles the bulk of data traffic, ensuring that information can travel quickly and efficiently across vast distances.
– Key Components:
– Submarine Cables: These are underwater fiber-optic cables that connect continents and enable international data transmission.
– Terrestrial Fiber-Optic Cables: High-capacity cables laid across land that connect major cities and regions within continents.
– Internet Exchange Points (IXPs): Physical locations where multiple ISPs and networks interconnect and exchange data.
1). A modem is a device that convert signals from digital to analogue and also convert analogue signals to digital signals.
This conversion character is what helps us to leap from a simple network to the Internet.
2). A router is a device that collects information connected to multiple computers, digital devices and send it to a modem.
While a modem is a device that converter of digital signals to analogue cable or analogue cable to digital signals.
Hence a modem is a signal converter while a router is a digital receiver or connector.
3). The job of the Internet service provider (ISP) is to connect information/data to the network of collective routers, modems and other ISPs. Vise versa.
4). The fibre optics cables buried under the sea across continents is the backbone of Internet that connects ISPs.
(1). A modem is a network of device that enables a computer to transfer data from telephone line (cable system) to computer and computer to telephone line.
A modem enable the transition from simple networking to broader Internet by converting digital data from a computer into analog (electrical) signals that can be transmitted over cable systems and vice versa.
(2). A modem is a device that converts signal between digital data used by computers and traditional cable systems or fiber optics, there by providing internet by connecting to an ISP (Internet service provider).
A Router is a device that directs data packets between simple (local) network and manage traffic to and from Internet by distributing the Internet connection from the modem to several devices.
(3). The major job of an ( ISP) Internet service provider is to provide Internet connectivity and related service to customers.
(4). Fiber optics cables.
1. A modem is a a device or program that enables a computer to transmit data over i.e telephone or cable lines. The modem helps us to take the leap from a simple network to the internet through modulation and demodulation, through the modem, information is passed to computers globally as it converts information to telephone signals which is transfered to isp’s which can communicate over vast distances and once information is passed through the isp’s,they are then transferred to modem which converts these telephone signals to electrical signals then to the router and then to the target computer or digital device
2. A modem turns electric signals from routers to digital signals while a router connects one or more computers together
3. Isp’s help to send messages from one network to another
4. The backbone of the internet is the connection of one isp to another through the fibre cables buried under the sea
