Computer Networking

An UDP sesion is created on a computer when an application starts listening on a UDP port. So basicaly it goes like this

Application says : "Hey OS, can you open port 45547 on interface X for me, I'm expecting some UDP packets on that port ?"

OS says : "Sure. Here, just listenon this socket handle for any events."

And then if any packets arrive from ANY IP in the world on interface X at port 45547, the application will be alerted through the given socket handle on which it listens.

Using the standard file() function to read large text files (say greater than 10 Mb) may give problems. You should use fopen() fread() fgets() instead.

these are the four types of the topologies such as

WAN:-Wide Area Network

LAN:- Local Area Network

MAN- Metropolitan Area network

CAN:- Campus Area Network

In these topologies meanings are clear for a name

Session Layer, this layer helps out with the task to carry information from one node (workstation) to another node (workstation). A session has to be made before we can transport information to another computer.

Yes, Port 53 is a widely-known port number. In Internet connections, every port labeled 1 to 1023 is considered a 'well-known' port. These ports are used as part of the process of going online or networking.

For the basics, if you are expecting to expand and gain more employees you would want to use a client server. Otherwise, using a peer to peer is easier to set up.

A direct connection between two countries is likely pretty expensive. Better solution would be for both offices to get internet from a local ISP... then establish a VPN between the sites. There are a lot of different products and methods to establish the VPN. Look for a local switch/router capable of establishing a VPN. Easiest is to use the same product on each end... so the default settings will be the same and most of the setup will be moot. Cisco product is called office connect.

Styles specified in a tag are referred to as "inline styles." These styles are applied directly within an HTML element using the style attribute, allowing for specific, immediate styling of that element without affecting others. Inline styles take precedence over external and internal stylesheets, making them useful for quick, one-off style adjustments. However, they are generally discouraged for extensive use as they can lead to less maintainable code.

Yes and no. Yes, you should not connect in WLAN part other cables except internet cable. No, you have other ports which are similar to each other and it doesnt' matter which of them you are using.

the address Class

- synchronization in which the decision instants is brought into alignment
with the received bit,i.e, the basic signaling element.

- it is used to generate a clock signal at the proper sampling instants. - it consists of non linear element followed by phase locked loop ( PLL ).

Private IP Address

Bus topology is the most popular topology. Justify.

A routable protocol contains a network address as well as a device address. Non-routable protocol, on the other hand, regulate the transfer of data and always makes use of interior routing system to transmit data.
