Long-term Evolution (LTE)
Long-Term Evolution (LTE) is a standard for wireless technology based upon GSM/EDGE and UMTS/HSPA technologies. It offers increased network capacity and speed to mobile device users, serving as an extension of 3G technology for high-speed mobile communications. LTE-Advanced (LTE-A) is an improvement over LTE that meets the criteria of 4G wireless communications as laid down by IMT-Advanced standards. It provides greater speeds and better quality of communications compared to standard LTE. Both LTE and LTE-A are used for mobile broadband communications and Voice over IP (VoIP) services, forming the backbone of modern mobile networks. ...
Read MoreWhat is algorithm for computing the CRC?
Cyclic Redundancy Check (CRC) is a block code that was invented by W. Wesley Peterson in 1961. It is commonly used to detect accidental changes to data transmitted via telecommunications networks and storage devices. CRC involves binary division of the data bits being sent by a predetermined divisor agreed upon by the communicating system. The divisor is generated using polynomials. So, CRC is also called polynomial code checksum. Before sending the message over network channels, the sender encodes the message using CRC. The receiver decodes the incoming message to detect error. If the message is error-free, then it ...
Read MoreWhat is WAN accelerator?
A wide area network accelerator (WAN accelerator) is a hardware component, software, or appliance executing in a virtualized environment that provides caching and optimization of WAN services. A WAN accelerator is also called a WAN optimizer or application accelerator. WAN accelerators are deployed to improve network performance over long-distance connections by reducing bandwidth usage and minimizing latency for data transmission across wide area networks. Working Principle A WAN accelerator provides services to speed up information flow between end users for imparting better network experience. Its primary target is to reduce the data volume to be transmitted through ...
Read MoreCable Internet
Cable Internet is a category of broadband Internet access that uses the infrastructure of cable TV networks to provide Internet services. Cable Internet provides connectivity from the Internet service provider (ISP) to end users in a similar manner as digital subscriber line (DSL) and fiber-to-the-home (FTTH). System Layout Broadband cable Internet access uses a cable modem termination system (CMTS) at a cable operator facility called a headend. The headend is connected to switching centers by high-bandwidth fiber trunk lines. Each switching center connects to one or more fiber nodes through fiber optic cables. Finally, local coaxial cables connect ...
Read MoreThe Data Link Layer Frame and Frame Fields
A frame is a unit of communication in the data link layer. The data link layer takes packets from the network layer and encapsulates them into frames. If the frame size becomes too large, then the packet may be divided into smaller sized frames. At the receiver's end, the data link layer picks up signals from hardware and assembles them into frames. Fields of a Data Link Layer Frame A data link layer frame has the following parts: Frame Header − Contains the source and destination addresses of the frame and control bytes. ...
Read MoreHTML cite Attribute
The cite attribute in HTML specifies a URL that points to a document or source explaining the reason for a modification. It is commonly used with elements like , , , and to provide context or justification for content changes and citations. Syntax Following is the syntax for the cite attribute − inserted text deleted text quoted text quoted content Where URL is the web address of the document that explains the reason for the insertion, deletion, or the source of the quotation. Using Cite with the INS Element The ...
Read MoreExecute a script when the user writes something in a search field in HTML?
The onsearch attribute in HTML allows you to execute a JavaScript function when the user performs a search action in a search input field. This event triggers when the user presses ENTER or clicks the clear button (×) in browsers that support it. Syntax Following is the syntax for the onsearch attribute − The onsearch attribute calls a JavaScript function when a search event occurs on the search input field. Example − Basic Search Event Following example demonstrates how to use the onsearch attribute to capture search input − ...
Read MoreHTML autocomplete Attribute
The autocomplete attribute in HTML controls whether the browser should automatically fill input fields based on previously entered values. When set to on, the browser displays suggestions from user's history, while off disables this functionality entirely. Syntax Following is the basic syntax for the autocomplete attribute − The autocomplete attribute can also accept specific values for better control − Attribute Values The autocomplete attribute accepts the following values − on − Enables autocomplete functionality. The browser will suggest values based on user's previous entries. off ...
Read MoreHow to set the range that is considered to be of high value in HTML?
Use the high attribute in HTML to set the range that is considered to be of high value. The high attribute is used with the element to define a threshold above which the measured value is considered high or above normal. The high attribute works in conjunction with other attributes like low, min, max, and optimum to create visual indicators for different value ranges. When a meter's value exceeds the high threshold, browsers typically display it in a different color to indicate the high state. Syntax Following is the syntax for the high attribute − ...
Read MoreHTML DOM Abbreviation Object
The HTML DOM Abbreviation Object represents the element in the Document Object Model. The element is used to display abbreviations or acronyms, often with a title attribute that provides the full expanded text. The Abbreviation object provides access to all the properties and methods of the element, allowing you to manipulate abbreviations dynamically using JavaScript. Syntax To access an abbreviation object using JavaScript − document.getElementById("abbreviationId") To create a new abbreviation object − document.createElement("abbr") Properties The Abbreviation object inherits all properties from the HTMLElement interface. The ...
