Buffer overflow detection technique
A buffer overflow is an anomaly where a program, while writing data to a buffer, overruns the buffer’s boundary and overwrites adjacent memory. There are several techniques: 1. NOP sled technique: A NOP-sled is the oldest and most widely known technique for successfully exploiting a stack buffer overflow. It solves the problem of finding the [...]

Routing confusion
Some vendors, like Cisco, have proprietary routing protocols that don’t “play well with others” and don’t meet routing standards for interoperability. Other vendors use standard routing protocols. This article on routing protocols might help you better understand the various routing protocols and their differences/similarities. Don’t misunderstand me, Cisco does use standard routing protocols, but like [...]

Bridge vs router
Bridging and Routing are both ways of performing data control, but work through different methods. Bridging takes place at OSI Model Layer 2 (Data-Link Layer) while Routing takes place at the OSI Model Layer 3 (Network Layer). This difference means that a bridge directs frames according to hardware assigned MAC addresses while a router makes [...]

Can VLANs communicate with each other and still block broadcast traffic?
A client on one VLAN (say 12) will not see broadcasts from clients on another VLAN (say 50). This SearchNetworking article describes VLANs. Broadcasts are not required for communication between VLANs. A route must be available though between VLANs for clients to communicate. ——————– VLANs, by definition, segregate broadcasts from other networks – they are [...]

Are LTO tapes backwards compatible. Why would I not be able to read old tapes?
They are compatible up to a point. LTO4 drives can read and write LTO4 & LTO3 and read only for LTO2. So if the original backup was done with a LTO2 or LTO3 drive it has the ability to read the tapes. If the backup was done with a LTO1 drive then the LTO4 drive [...]

Ethernet Topology: the 10BASE-T standard
10BASE-T Ethernet is a very old standard, found only in very old networks. The answer to this question can be given by analysing what exactly 10BASE-T means: <b>10 </b> The number 10 represents the frequency in MHz (Mega HertZ) for which this cable is made. In this case it is 10 MHz. The greater the [...]
