Computer Networking

we use straight cable to connect between the router and switch as router and switch are different devices.

The maximum frame size wireless device can transmit without fragmenting the frame.

A collision happens when two devices that use the same medium transmit packets at exactly the same time. The two packets can corrupt each other, and the result is a group of unreadable pieces of data. If a packet results in a collision, the packet is discarded and it must be transmitted again. This adds to the overhead on the network and can reduce the throughput or speed of the network. Larger frames are more likely to collide with each other than smaller frames. You can make the wireless packets smaller by lowering the fragmentation threshold. If you lower the maximum frame size, it can reduce the number of retransmissions caused by collisions, and lower the overhead caused by retransmissions. However, making frames smaller introduces a different kind of overhead. Smaller frames introduce more overhead on the network too. This is especially true on a wireless network, because every fragmented frame sent from one wireless device to another wireless device requires the receiving device to acknowledge the frame. In times of high packet error rates (over five or ten percent collision or errors), lowering the fragmentation threshold can help improve performance of the wireless network. The time that is saved from reducing re-transmissions can be enough to offset the extra overhead added by using smaller packets. This can result in higher throughput. If the rate of packet error is low and you lower the fragmentation threshold, wireless network performance will decrease. This is because lowering the threshold adds protocol overhead and reduces protocol efficiency. The default maximum value 2346 is recommended.

Using OSI reference model explain the data communication between two hosts?

A file server is a computer attached to a network that has the primary purpose of providing a location for the shared storage of computer files(such as documents, photographs, databases, etc.) that can be accessed by the workstations that are attached to the computer network..

In persistent HTTP without pipelining, the browser first waits to receive a HTTP response from the server before issuing a new HTTP request. In persistent HTTP with pipelining, the browser issues requests as soon as it has a need to do so, without waiting for response messages from the server.

Yes. Apache Tomcat is a Web Server

The switch would broadcast frames out each port except the originating port until the switch learned all the MAC addresses connected to the switch.

Port numbers are used:
1) To distinguish different applications on the server.
2) To distinguish different conversations (for example, different browser windows) on the client machine.

DNS and DHCP Management are both Administrative Tools.

DNS Management is run from the DNS MMC snap in.

This can be accessed by using the Run commend, and inputting: dnsmgmt.msc

DHCP Management is run from the DHCP MMC snap in.

This can be accessed by using the Run commend, and inputting: dhcpmgmt.msc

These snap-ins must be installed on the system, or you will be unable to access them.

The advantages of client server approaches particularly centralized services are as follows.

· All data is stored on the servers, which generally have far greater security controls than most clients.

· Servers can better control access and resources, to guarantee that only those clients with the appropriate permissions may access and change data.

· Since data storage is centralized, updates to that data are far easier to administer in comparison to a Peer-to-peer model. In the end, data updates may need to be distributed and applied to each peer in the network, which is time-consuming as there can be thousands or even millions of peers.

· It functions with multiple different clients of different capabilities.

· Enables the roles and responsibilities of a computing system to be distributed among several independent computers that are known to each other only through a network. This creates an additional advantage to this architecture; greater ease of maintenance. For example, it is possible to replace, repair, upgrade, or even relocate a server while its clients remain both unaware and unaffected by that change.

· Server hardware is designed to serve requests from clients quickly and redundancy and back-up, data can be stored in redundant ways making for quick restore in case of problems and more flexibility, new technology can be easily integrated into the system and interoperability, all components work together, and ease of use; server can be accessed remotely and across multiple platforms.

· It is possible to remove or add clients without affecting the operation of the network and without the need for major modification.

· Since the client and server component namely the user interface and database management are separated in the design of client-server model it eases the effort of database administrator and also developers. This is because developers can concentrate on user application alone. Also for example if a user interface change occurs the system can be changed with little effort by making changes only in the client side without making server component changes.

· Performance is also increased without much effort. For example if a organization decides to go for a system for server side to increase performance this can be done without affecting the user application because client component of client-server model need not be disturbed in this case.

· If we are using database server, we can use an automatic scheduler to back-up our database without having to exclude users from the database.

You have a class C network connection. Since the subnet mask was not specified I can't tell if it is a traditional class C or if the network has been subnetted.

Yes, the standard is backwards compatible.

wireless modem is called that because it has a wirelss router built in. wireless router just a wireless router. if your cable is not wireless you can buy a wireless router or a cable modem with wireless router

LAN is local area network, which is pretty much inside the building. WAN is wide area network or connections from building to building, which could be a few feet or many miles.

The purpose is to allow communications to occur between buildings long distances apart, but within the same company.
