What is difference between swift or wire transfer?
The difference between swift and wire transfer is that swift sends information from one bank or other financial institution to another. Swift sends the payment orders, but not the finances. With a wire transfer funds are transferred from one person to another.
What is elevator auto-homing?
Elevator auto-homing sends the elevator to a predetermined floor when not in use. This is usually the first floor. Hydraulic jacks and cables raises and lowers the elevator cars.
If sender sends a series of packets to the same destination using 5 bit sequence number .if the sequence number starts with 0 then what is the sequence number after sending 100 packets?
0011
What is the difference between reply and reply all?
"Reply" is a response only to the person who sent you the email. "Reply all" or "Reply to all" sends your reply not only to the person who sent you the email but also to everyone else who received the same email that you did. In other words: "A" sends email to "B", "C", "D", "E" and "F". If "B" responds to "A", "B's" response will also be sent to C, D, E and F. Ideal for conversations where everyone on the list needs to see the reply, but something you would not want to use for most email as the effect is to fill a lot of mail boxes with a lot of irrelevant mail.
Why parity bit is used?
Parity bits are mainly meant for error detection in serial communication.It will be use full for determining the correctness of data sent from transmitter to receiver.even parity A wants to transmit: 1001 A computes parity bit value: 1^0^0^1 = 0 A adds parity bit and sends: 10010 B receives: 10010 B computes parity: 1^0^0^1^0 = 0 B reports correct transmission after observing expected even result.odd ParityA wants to transmit: 1001 A computes parity bit value: ~(1^0^0^1) = 1 A adds parity bit and sends: 10011 B receives: 10011 B computes overall parity: 1^0^0^1^1 = 1 B reports correct transmission after observing expected odd result.Transmission error detection on even parityA wants to transmit: 1001 A computes parity bit value: 1^0^0^1 = 0 A adds parity bit and sends: 10010 *** TRANSMISSION ERROR *** B receives: 11010 B computes overall parity: 1^1^0^1^0 = 1 B reports incorrect transmission after observing unexpected odd result.Transmission error detection on odd parityA wants to transmit: 1001 A computes even parity value: 1^0^0^1 = 0 A sends: 10010 *** TRANSMISSION ERROR *** B receives: 10011 B computes overall parity: 1^0^0^1^1 = 1 B reports incorrect transmission after observing unexpected odd result.Refference:Wikipedia
How is a cidr subnet mask implied?
With CIDR and VLSM, the subnet mask can no longer be implied. The routing protocol must include information about the subnet mask, when a router sends updates to other routers. This makes some older routing protocols unsuitable for such cases; for example, RIP version 1 is unsuitable, but RIP version 2 was changed so that it included the subnet mask.With CIDR and VLSM, the subnet mask can no longer be implied.

What is the difference between Link state routing and distance vector routing through examples?
In a distance vector routing protocol, such as RIP or EIGRP, each router sends its routing table to neighboring routers. The routers don't know the topology, i.e., how other routers are interconnected. In a link state routing protocol, such as OSPF or IS-IS, routers first exchange information about connections within the network (or an area of the network), and build a topology table. Then each router uses Dijkstra's algorithm to calculate the best route to each destination.
Which feature of RIPv2 enables it to function as a classless routing protocol?
RIPv2 sends subnetmasks in the routing table updates. RIPv1 does not, which causes it be class-full.
What is the difference between direct and indirect routing?
When a system sends an IP packet to another system in a network, it is direct routing. When a system sends an IP packet to another system via a third system or more systems in a network, it is indirect outing.
Is a device that sends or receives documents over a telephone line?
That's called a Modem... now superseded by broadband routers.
When a router does not have an interface for the destination network it sends the traffic to where?
If a router has a route in its routing table, it will have a next hop IP address and / or outbound interface. If a router does not have a route in its routing table the packet will be dropped.
How often does Internet Explorer send out updates for their software?
Internet Explorer sends out updates whenever they are available, and not on any given schedule.
What device is typically as the default getaway for a computer?
The IP address of the router or firewall's interface that is connected to your network. It then performs routing, filtering, and as a last resort sends it out into the internet.
A network administrator uses the RIP routing protocol to implement routing within an autonomous system What are two characteristics of this protocol Choose two?
It uses the Bellman-Ford algorithm to determine the best path. It displays an actual map of the network topology. It offers rapid convergence in large networks. It periodically sends complete routing tables to all connected devices. It is beneficial in complex and hierarchically designed networks.
What does a router does in a LAN OR WAN environment?
It decides where data should go on a network. Imagine a company's network. One user sends an email to someone else. Their computer sends the email to the router, which then sends it out to the mail server. The mail server then sends out a message to the other user's computer telling them that they have received an email. The router picks this up and sends it in the correct direction.
How important is TTL to network security what is TTL for and can a Hacker use it to harm you PC or network?
TTL stands for "Time To Live". This is a piece of data in a network packet that specifies how many routers the packet can pass through before the packet expires and is thrown away. Every router that the packet travels through subtracts one from the TTL counter. When it reaches zero, the packet expires. The router will drop the packet, and then send a message back to the computer that sent the packet telling it that the packet has expired. The purpose of the TTL counter is to make routing loops less dangerous. Let me explain.... Routers are devices that look at an incoming data packet and decide where to send it to get it one step closer to its destination. It's possible for one or more routers to be configured such that router A sends the packet to router B, which sends it to router C, which sends it to router A, which then starts it over again. Without the TTL counter, this packet (and any subsequent packet sent to the same destination) would circulate endlessly, taking up bandwidth until someone fixes the routing loop. However, with TTL, each router subtracts one from the TTL counter until eventually the counter hits zero and the packet goes away, giving someone time to fix the problem before the links are so congested with looping packets that it's no longer possible to talk to the router. TTL can affect network security in a couple of ways. Most operating systems set the TTL counter to 64 or 128, which is a pretty large number that will guarantee your packet can get across the Internet. To improve your network security, you can set your TTL counter to a low number. If your internal network is only four routers wide, you can set your TTL to 4. This will ensure that any packets generated on your network will not travel very far beyond your internal network. An attacker can also use the TTL feature to probe your network for the existence and address of your routers. This feature is used by the "traceroute" or "tracert" utility. It works by sending out a packet with a TTL of 1. The first router that the packet encounters will decrement the TTL to 0, drop the packet, then send a message to the traceroute program telling it that the packet expired. By looking at the source address of this packet, traceroute knows the address of the first router. Next traceroute sends a packet with a TTL of 2, which causes the packet to expire at the second router, which sends a message back to traceroute and exposing its address. And so on. Once an attacker knows the addresses of your routers, he or she can start working on compromising them, which can cause you no end of security problems. The solution is to prevent these packets from reaching your routers by using a firewall to block them. HTH, Gdunge
How does a crossover cable connect two routers?
It connects the pins that are used for transmitting on one router to the pins that are used for receiving on the other router.
