Operating System can be defined as an interface between user and the hardware. It provides an environment to the user so that, the user can perform its task in convenient and efficient way. Operating System Definition and Function In the Computer System (comprises of Hardware and software), Hardware can only understand machine code (in the...
Routing algorithms are software programs that implement different routing protocols. They work by assigning a cost number to each link; the cost number is calculated using various network metrics. In order to transfer the packets from source to the destination, the network layer must determine the best route through which packets can be transmitted. Whether the...
With everything turning digital, Cyber Security threats have been growing each day. And a common problem for every IT Security professional right now, is how to prevent these fraudulent activities and save billions of dollars annually ? To prevent cyber threats, it is necessary to analyse all the data and detect any such risks. That is...
Digital Transmission Data can be represented either in analog or digital form. The computers used the digital form to store the information. Therefore, the data needs to be converted in digital form so that it can be used by a computer. DIGITAL-TO-DIGITAL CONVERSION Digital-to-digital encoding is the representation of digital information by a digital signal....
TCP/IP model The TCP/IP model was developed prior to the OSI model. The TCP/IP model is not exactly similar to the OSI model. The TCP/IP model consists of five layers: the application layer, transport layer, network layer, data link layer and physical layer. The first four layers provide physical standards, network interface, internetworking, and...
What is OSI Model? The OSI Model is a logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems. The Open System Interconnection (OSI Model) also defines a logical network and effectively describes computer packet transfer by using various layers of protocols. Characteristics of OSI Model...
Computer Memory A computer is an electronic device that takes raw data as input and, processes it, then provides the desired result. It has the potential to execute programmed computations quickly and with great accuracy. Put in another way, the computer receives input such as data and stores it together with instructions in memory (use...
A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection. How does a router work? Routers guide and direct network data, using packets...
Computer Network Security Computer network security consists of measures taken by business or some organizations to monitor and prevent unauthorized access from the outside attackers. Different approaches to computer network security management have different requirements depending on the size of the computer network. For example, a home office requires basic network security while large businesses...
Examples Of Wide Area Network: Mobile Broadband: A 4G network is widely used across a region or country. Last mile: A telecom company is used to provide the internet services to the customers in hundreds of cities by connecting their home with fiber. Private network: A bank provides a private network that connects the 44 offices. This network...
