What is Memory Leak

Memory Leak: When a program needs to store some temporary information during execution, it can dynamically request a chunk of memory from the system. However, the system has a fixed amount of total memory available. If one application uses up all of the system’s free memory, then other applications will not be able to obtain the memory that they require. The implications of a “memory starved” application can range from a graceful shutdown to an unexpected crash. Most large scale applications regularly request memory, so running out of system memory tends to have a domino effect. Even if the applications do not terminate, the system will slow down to a crawl—or even hang—in low memory conditions. Clearly, none of these results are desirable, so the system never wants to run out—or run low—of memory. It is the responsibility of each application to “free” dynamically requested memory when they are finished using it. Freeing the memory returns it to the system, where it can be re–allocated

Communications Protocol & OSI Model Overview

A communications protocol is a system of digital message formats and rules for exchanging those messages in or between Computing systems and in telecommunications. A protocol may have a formal description. Protocols may include signaling, authentication and error detection and correction capabilities. A protocol definition defines the syntax, semantics, and synchronization of communication; the specified behavior is typically independent of how it is to be implemented. A protocol can therefore be implemented as hardware or software or both. Introduction While there is no generally accepted formal definition of "protocol" in computer science, an informal definition, based on the previous, could be "a set of procedures to be followed when communicating". In computer science the word algorithm is a synonym for the word procedure so a protocol is to communications what an algorithm is to mathematics. Communicating systems use well-defined formats for exchanging

Microsoft Prepares Super-Cheap Windows Laptops to Battle

Microsoft Prepares Super- Cheap Windows Laptops to Battle  Microsoft to give Chromebook some stiff competition. At the company's annual Worldwide Partner Conference, Microsoft COO Kevin Turner revealed that HP is planning to release   a $199. Windows laptop called the 'Stream' this holiday season and at the same time they are planning to release 7and 8 inch versions of tablets for just $99. Turner said, "We are going to participate at the low-end" and he was quick to add that, "We've got a great value proposition against Chromebooks, we are not ceding the market to anyone, " reports Times of India. At these super affordable price points, the Stream  would come at a bargain, beating out many of Google's affordable cloud powered laptops like Dell Chromebook 11 and Toshiba Chromebook. Turner didn't provide specification for HP's "Strean" device, but he did specify $249 laptop options from Acer and Toshiba. Acer's low-cost lapt
