OpenERP Requirements Specification (SRS)
Business requirement specification (BRS) : It’s having all the business rules , it will prepared by Business analyst/Client, but we are unable to understand that business rules , so our domain experts will create FRS or SRS, so that we can easily understand. It contains brief description about the application. It is the 1st process that should befollowed by every Organization [...]
Read MoreDifferent Software Testing Domains
Most of the times, we testers keep shifting from different projects. These projects can be in the same domain or different like Retail, Utilities, Healthcare, e-commerce, banking etc…. Here is a brief description about different domains, which may help most of the testers to understand the importance of Domain Knowledge. BFSI: BFSI stands for Banking, [...]
Read MoreEthernet What is NDIS, packet driver, ODI.?
NDIS is a Microsoft/3com puppy that allows “stacking” of multiple protocols for a single underlying driver. Essentially it allows a single Ethernet card in a PC (it’s not limited to Ethernet) to speak many different network “languages”, and usually at the same time. A packet driver is another method of allowing multiple protocols to access [...]
Read MoreEthernet What is a driver?
Typically the software that allows an Ethernet card in a computer to decode packets and send them to the operating system and encode data from the operating system for transmission by the Ethernet card through the network. By handling the nitty-gritty hardware interface chores, it provides a device-independent interface to the upper layer protocols, thereby [...]
Read MoreEthernet What is a Kalpana EtherSwitch?
A device that works sort of like a bridge, but off a different principle. It’s advantages are that it is extremely fast and can “bridge” more than one packet at a time (it is not limited to two interfaces as a traditional bridge is). Disadvantages are that it does not understand spanning tree and doesn’t [...]
Read MoreAre there problems mixing Bridging & routing?
You should be very careful about running bridges providing links in parallel to a router. Bridges may forward broadcast requests which will confuse the router there are lots of protocols you may not think of filtering (e.g. ARP, Apple ARP over 802.3 etc. etc.). Also, DECnet routers have the same MAC address on all ports. [...]
Read MoreEthernet-should I use a router or a bridge?
There is no absolute answer to this. Your network layout, type and amount of hosts and traffic, and other issues (both technical and non-technical) must be considered. The following are the pros and cons of each: Routing: + Can route between different media (although FDDI to Ethernet bridges are becoming common via the Translation Bridging [...]
Read MoreEthernet What exactly does a router?
Routers work much like bridges, but they pay attention to the upper network layer protocols (OSI layer 3) rather than physical layer (OSI layer 1) protocols. A router will decide whether to forward a packet by looking at the protocol level addresses (for instance, TCP/IP addresses) rather than the MAC address. Because routers work at [...]
Read MoreEthernet What is a remote bridge?
A bridge as described above that has an Ethernet (or token-ring) interface on one side and a serial interface on the other. It would connect to a similar device on the other side of the serial line. Most commonly used in WAN links where it is impossible or impractical to install network cables. A high-speed [...]
Read MoreEthernet What does a “learning bridge”?
A learning bridge monitors MAC (OSI layer 2) addresses on both sides of its connection and attempts to learn which addresses are on which side. It can then decide when it receives a packet whether it should cross the bridge or stay local (some packets may not need to cross the bridge because the source [...]
