What Does Dial-Up Connection Mean?

A dial-up connection uses a standard phone line and analog modem to access the Internet at data transfer rates (DTR) of up to 56 Kbps.

A dial-up connection is the least expensive way to access the Internet, but it also slowest connection.

A dial-up connection is established when two or more communication devices use a public switched telephone network (PSTN) to connect to an Internet service provider (ISP).

Many remote areas depend on Internet dial-up connections because broadband and cable are rare in remote areas with low population numbers.

ISPs often provide free dial-up connections, a viable alternative for budget-conscious subscribers.

Computer networking enables devices and endpoints to be connected to each other on a local area network LAN or to a larger network, such as the internet or a private wide area network (WAN). This is an essential function for service providers, businesses and consumers worldwide to share resources, use or offer services, and communicate. Networking facilitates everything from telephone calls to text messaging to streaming video to the internet of things (IoT).

Computer networking refers to connected computing devices (such as laptops, desktops, servers, smartphones, and tablets) and an ever-expanding array of IoT devices (such as cameras, door locks, doorbells, refrigerators, audio/visual systems, thermostats, and various sensors) that communicate with one another.

How does a computer network work

Specialized devices such as switches, routers, and access points form the foundation of computer networks.

Switches connect and help to internally secure computers, printers, servers, and other devices to networks in homes or organizations. Access points are switches that connect devices to networks without the use of cables.

Routers connect networks to other networks and act as dispatchers. They analyze data to be sent across a network, choose the best routes for it, and send it on its way. Routers connect your home and business to the world and help protect information from outside security threats.

While switches and routers differ in several ways, one key difference is how they identify end devices. A Layer 2 switch uniquely identifies a device by its “burned-in” MAC address. A Layer 3 router uniquely identifies a device’s network connection with a network-assigned IP address.

Today, most switches include some level of routing functionality.

MAC and IP addresses uniquely define devices and network connections, respectively, in a network. A MAC address is a number assigned to a network interface card (NIC) by a device’s manufacturer. An IP address is a number assigned to a network connection.


Dial-up refers to an Internet connection that is established using a modem. The modem connects the computer to standard phone lines, which serve as the data transfer medium. When a user initiates a dial-up connection, the modem dials a phone number of an Internet Service Provider (ISP) that is designated to receive dial-up calls. The ISP then establishes the connection, which usually takes about ten seconds and is accompanied by several beeping an buzzing sounds.

After the dial-up connection has been established, it is active until the user disconnects from the ISP. Typically, this is done by selecting the “Disconnect” option using the ISP’s software or a modem utility program. However, if a dial-up connection is interrupted by an incoming phone call or someone picking up a phone in the house, the service may also be disconnected.

What are the types of dial up network?

  • Dial Up Connection:. Dial up connections are the oldest, most out of date connections still available today. …
  • DSL. DSL stands for Digital Subscriber Line. …
  • FTTN (Fiber To The Node) …
  • Ethernet Over Cable. …
  • T1. …
  • T3. …
  • Fiber Optics. …
  • Satellite. etc.

What is a feature of dial up connection?

the use of multiple channels which can carry different types of services. the use of different frequencies to carry voice and data signals on the copper telephone wire. the use of an analog modem to transmit data over voice telephone lines.

Advantages of dialup (dial up) internet access:

1) Everyone has a phone line, dialup connection is available to everyone with a computer and a modem (including built-in modem).

2) Dialup may be the only choice available for rural or remote areas where broadband connection is not available.

3) Low cost. You can get dialup internet access for under $10/month.

4) Easy setup. Simple equipment.

Disadvantages of dialup (dial up) connection:

1)    Your phone line is occupied when you are connected to the internet. Some ISPs provide caller ID service which allows you to see who is calling while you are connected. This is still quite inconvenient if you are downloading a file and have to abandon your download to answer the call.

2)    Sometimes you may get a busy signal when calling the access numbers, this rarely happens nowadays as most ISPs will let you choose multiple access numbers and then select the one that is available automatically.

3)    Some ISPs charge the user based on the connection duration, an additional cost on top of the monthly fee.

4)    The data transmission rate is rather low. With a rate of 56 Kbps or less, you will have a hard time downloading large files such as video clips, software, sharing photos with your friends and families, or playing online computer games.
