An infiniteloop-- sometimes called anendless loop-- is a piece ofcodethat lacks a functional exit so that it repeats indefinitely. In computer programming, a loop is a sequence ofinstructionsthat is continually repeated until a certain condition is reached. A while loop continues running until t...
What's a "do-while" loop? A "do-while" loop is similar to a "while" loop, but the condition is checked at the end of each iteration. This means the loop will always execute at least once, even if the condition is initially false. ...
Print request.An employee sends a print request from a computer to a printer located in another part of the office. The employee's computer is a node on the network. The request travels over the network and through a series of other nodes -- a router, for example -- on the company LA...
A network driver is a software program that controls a device used to connect a computer to a network. Network drivers control the interface between a computer and a given network. It is familiar with the protocol being used by the computer network, creating a unique identification for the ...
What is a VPN and how do I add one to my device?VPN is short for Virtual Private Network. VPNs have multiple purposes. They are often used within organisations as internal networks, but are also often used by individuals to add an extra layer of Security and Privacy, especially w...
a physical form. Instead, the network interface can be implemented in software. For example, the loopback interface (127.0.0.1for IPv4 and::1for IPv6) is not a physical device but a piece of software simulating a network interface. The loopback interface is commonly used in test ...
The OSPF RIB displays an inter-area route through R2 12.0.0.2, this is best path as shown by the Flags: RIB, the output also displays two possible paths to reach 5.5.5.0, via R3 and R4, these possible backup path are represented by a Type-3 LSAs originated by the ABRs R3 0.0.0.3 ...
A for loop is a programming construct that allows a block of code to be executed repeatedly until a certain condition is met. The for loop works by running the code within its scope until the specified condition is no longer true, allowing you to perform tasks such as iterating over a li...
Plan.When you're faced with a challenge, pause and notice how you're approaching the problem. Note what is or isn't working. Create a plan. Be strategic by breaking down your tasks into smaller, more manageable ones. Seek help from others during your planning process. By talking with som...
A loopback test is a simple method to determine whether communication circuits are functioning at a basic level. It often involves connecting a loopback device to a circuit and verifying that transmitted data returns to the sender. Loopback testing is commonly performed on serial, network and ...
