Modern scenario of information technology:

Image
The modern scenario of information technology: Introduction: Information technology (IT) is the technology that merges the computing network system with high-speed communication links carrying any kind of data in the form of text, sound, images. and videos etc. Information can be defined as the facts and figures about anything that can transfer data of any kind. i.e. The know-how about any object of the universe that exists and plays its role in any network computer system. The system is any identified and known work that accepts data/information into itself, manipulates in the shape of certain output(s), and delivery so that it becomes useful and meaningful. Modern Scenario The modern impact of computer system Information Technology has broadened the base of comput ing and communication through satellite, fiber-optic, mobile phones. Thus enhancing the implications of this shift from single isolated technologies to a unified digital convergence and enabling the computer users to experi

Deadlock Questions and Answers pdf

Deadlock Questions and Answers pdf Define a deadlock? A process is said to be in a state of deadlock if it is waiting for a particular event (e.g. allocation of resources) that will never occur. Name four necessary conditions for Deadlock? Mutual Exclusion  Hold-and-Wait No Preempting  Circular Wait Describe the Mutual Exclusion condition for deadlock? Mutual exclusion condition indicates the locking of resources in exclusive mode, also known as a non-shareable mode. Each resource may be allocated to only one process at a time. If another process needs to use that resources, then the requesting process must wait until the resources have been released. What is the Hold-and Wait condition for deadlock? In a deadlock, each involved process holds one or more resources and waits for additional resources, which are currently being held by other processes in the system. It means that a deadlock may occur only if every involved process holds one or more resources and further needs additional r

What is the bus interconnection?

 What is the bus interconnection? Introduction: We know that a computer consists of a CPU, Main Memory MM, and I/O unit. For data to flow between these components we need some kind of interconnections, which is another very important component of the overall computer architecture. These components are interconnected by using a set of parallel lines to transmit the data from one location to another. Each of these lines can be used to transfer a sequence of bits from one component to the other component for data transfer. Definition: Each of these lines can be used to transfer a sequence of bits for communication from one component of the computer to the other component. This set of parallel lines is called a BUS. The system interconnection is used to communicate channel. System Bus: The bus used to connect the main components of a computer to the other component is called the system bus. Generally, the purpose of computers has a 70-100 line system bus.  The system bus is divided into th
