The transport layer is responsible for error-free, end-to-end delivery of data from the source host to the destination host. It corresponds to the transport layer of the OSI model. The functions of the transport layer are: It facilitates the communicating hosts to carry on a conversation.It provides an interface for the users to the underlying network.It can provide for a reliable connectio.....
The application layer (Layer 7) is the topmost layer of the OSI model. It specifies the interfaces and supports services to the end users for network access. The main functions of the application layer are as follows: It provides a virtual network terminal through which a user can log on to the remote host on the network.It provides facilities so that a user can access and retrieve files in.....
A number of design issues exist for the layer to layer approach of computer networks. Some of the main design issues are as follows: Network channels and components may be unreliable, resulting in loss of bits while data transfer. So, an important design issue is to make sure that the information transferred is not distorted. Networks are continuously evolving. The sizes are continually inc.....
A wide area network (WAN) is a computer network that covers a large geographical area comprising a region, a country, a continent or even the whole world. WAN includes the technologies to transmit data, image, audio and video information over long distances and among different LANs and MANs. WANs have a large capacity, connecting a large number of computers over a large area, and are inhere.....
A Local Area Network (LAN) is a private network that connects computers and devices within a limited area like a residence, an office, a building or a campus. On a small scale, LANs are used to connect personal computers to printers. However, LANs can also extend to a few kilometers when used by companies, where a large number of computers share a variety of resources like hardware (e.g. pr.....
In the Bucket Sorting technique, the data items are distributed in a set of buckets. Each bucket can hold a similar type of data. After distributing, each bucket is sorted using another sorting algorithm. After that, all elements are gathered on the main list to get the sorted form. Time Complexity: O(n + k) for best case and average case and O(n^2) for the worst case. Space Complexity: O(n.....
Bubble Sort is a comparison based sorting algorithm. In this algorithm adjacent elements are compared and swapped to make the correct sequence. This algorithm is simpler than other algorithms, but it has some drawbacks also. This algorithm is not suitable for a large number of data set. It takes much time to solve the sorting tasks. Time Complexity: O(n) for best case, O(n^2) for average an.....
Like the binary search, it also separates the lists into sub-lists. This procedure divides the list into three parts using two intermediate mid values. As the lists are divided into more subdivisions, so it reduces the time to search a key value. Time Complexity: O(log3 n)Space Complexity: O(1), , Input: An sorted array, start and end location, and the search key Output: location of th.....
For the binary search technique, the lists are divided into equal parts. For the interpolation searching technique, the procedure will try to locate the exact position using interpolation formula. After finding the estimated location, it can separate the list using that location. As it tries to find exact location every time, so the searching time reduces. This technique can find items easi.....
I want to set background color for my web page in HTML. Is the bgcolor attribute supported in HTML5? If not, then what can be used to easily set background color in HTML. The following is my HTML: ,
To set the background color in HTML, use the style attribute. The style attribute specifies an inline style for an element. The attribute is used with the HTML <body> tag, with the CSS property background-color. HTML5 do not support the <body> tag bgcolor attribute, so the CSS style is used to add background color. The bgcolor attribute deprecated in HTML5. Just keep in mind, th.....
