What is ATM frame relay and X 25?
Difference between of Frame Relay and X.25 : It performs Hop-to-Hop error and flow control at data link layer. It does not support End-to-End flow and error control. It performs End-to-End flow and error control at network layer. Congestion control is required in frame relay. Congestion control is not required in X.
What is the transfer rate of x 25 protocol?
X. 25 is an analog packet switching network. It can be considered Slow Packet Switching. The transfer speeds are typically 56 kbps to 2.08 Mbps.
What is the MTU size for X 25?
Thus X. 25 packets tend to be short – 128 0r 256 bytes as opposed to 1500 bytes or more for more modern protocols.
What protocols are used in the internet layer?
The Internet Protocol Stack
- Internet Protocol (IP)
- User Datagram Protocol (UDP)
- Transmission Control Protocol (TCP)
- Transactional Transmission Control Protocol (T/TCP)
- TCP/IP and OSI/RM.
Which of the following is used by X 25 as its DTE device?
With X. 25, the PAD (or router) is known as data-terminating equipment (DTE).
What is the local loop or last mile?
In telephony, the local loop (also referred to as the local tail, subscriber line, or in the aggregate as the last mile) is the physical link or circuit that connects from the demarcation point of the customer premises to the edge of the common carrier or telecommunications service provider’s network.
What is Frame Relay WAN?
Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology.
What is used to send packets from one network to another network?
The Ethernet protocol In casual conversation, you may hear the term “handshake” used as a synonym for the term “protocol”. The ethernet protocol is one where devices get each other’s attention by sending communications messages or “packets” onto the network whenever they need to.
What does TCP stand for?
Transmission Control Protocol

How do routers use IP address to determine data?
Routers forward packets based on the destination address they find in the IP packet header, and the information they themselves know about how to reach the identified destination. Routers store information internally about destination networks in tables called ‘routing tables’.
Do all routers have the same IP address?
This IP address is provided by your ISP and is assigned to the device that your modem is connected to, which is typically your router. Therefore, all devices connected to the router (whether wired or wirelessly) will share the same external IP address.
How is IP address written?
An IP address is typically written in decimal digits, formatted as four 8-bit fields separated by periods. Each 8-bit field represents a byte of the IP address. This form of representing the bytes of an IP address is often referred to as the dotted-decimal format.
How do you know which IP address is being used?
How to Find All IP Addresses on a Network
- Open the command prompt.
- Enter the command “ipconfig” for Mac or “ifconfig” on Linux.
- Next, input the command “arp -a”.
- Optional: Input the command “ping -t”.
What is IP address static?
Static IP addresses An Internet Protocol (IP) address is a unique number assigned to each computer on a network. A computer on the Internet can have a static IP address, which means it stays the same over time, or a dynamic IP address, which means the address can change over time.
What is IP address example?
An IP address is a string of numbers separated by periods. IP addresses are expressed as a set of four numbers — an example address might be 192.158. 1.38. Each number in the set can range from 0 to 255.
Does IP address change with WiFi?
For example, if you’re browsing on your home Wi-Fi connection on your smartphone, you can turn the Wi-Fi setting off and use mobile data. This will change the IP address because a different one is assigned for each network connection.
What happens if 2 devices have the same IP address?
For a system to communicate via a network, it must have a unique IP address. Conflicts arise when two devices are on the same network trying to use the same IP address. When this occurs, both computers end up not being able to connect to network resources or perform other network operations.
Is IP address changes automatically?
Or put more simply DHCP is the process your Internet Service Provider (ISP) uses to assign an IP Address to your home or business. Your ISP can either configure your IP address to be static (it stays the same) or dynamic (it can change). Most residential customers have a dynamic IP address, meaning that it can change.
Is IP address based on WIFI or device?
The external IP address is assigned by your ISP to your router which in turn assigns different internal IP addresses to all devices in the network. When a server sends you some data, it will be transmitted only to your device by your router (because you requested it) and not your dad’s.
What is IP address for WiFi?
Android users can click on the network name in their WiFi settings, and it will show the IP address. Your public IP address is the main IP address to which your home or business network is connected. This IP address connects you to the world, and it’s unique for all users.
Can two phones have the same IP address?
No, it’s because it’s very common for hundreds or even thousands of mobile phones all to be sharing the same IPv4 address on the internet. The way this is done is essentially the same as what happens when all your home WiFi devices share the single internet IP address allocated to your home router by your ISP.
Is IP address per device?
An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.
Is IP address unique for every device?
All computers and other devices connected to a network, such as smartphones, tablets, and fax machines, have a unique IP address. No two computers on the network may have the same IP address. Without the IP address, computers and mobile devices would not be able to communicate with each other.
What is IP address types?
There are four types of IP addresses: public, private, static, and dynamic. An IP address allows information to be sent and received by the correct parties, which means they can also be used to track down a user’s physical location.
