Cloud computing refers to a client-server computing framework where resources are managed in a centralized fashion. It is provided as a pay-per-use service. Cloud computing makes the system all-time accessible.Grid computing refers to a network of the same or different types of computers whose target is to provide an environment where a task can be performed by multiple computers together on a need basis. Each computer can work independently as well. Grid Computing is used internally by organizations.Read through this article to find out more about Cloud Computing and Grid Computing and how they are different from each other.What is ...

A cluster computer refers to a network of same type of computers whose target is to work as one collaborative unit. Such a network is used when a resource-hungry task requires high-computing power or memory. Two or more same types of computers are clubbed together to make a cluster and perform the task.Grid computing refers to a network of same or different types of computers whose target is to provide an environment where a task can be performed by multiple computers together on need basis. Each computer can work independently as well.Read through this article to find out more about ... Read More

PagingPaging is a memory management technique in which process address space is broken into blocks of the same size called pages (size is power of 2, between 512 bytes and 8192 bytes). The size of the process is measured in the number of pages. Similarly, main memory is divided into small fixed-sized blocks of (physical) memory called frames and the size of a frame is kept the same as that of a page to have optimum utilization of the main memory and to avoid external fragmentation.Similarly, main memory is divided into small fixed-sized blocks of (physical) memory called frames and ...

LANs are privately owned and span a smaller geographical area (restricted to a few kilometers). It can be used in various settings, including offices, residences, hospitals, and schools. The setup and management of a LAN is quite straightforward. Just like a traditional wired LAN in which the connected devices transmit data over Ethernet cables, whereas in a WLAN, the connected devices transmit data through Wi-Fi. Mobile users can connect to a WLAN through wireless connection. The IEEE 802.11 group of standards describe the technologies for LANs. Go through this article to find out more about LAN and WLAN ...

Wireless WAN is a type of WAN that uses only wireless connections. A WAN in general is a network of local area networks (LANs) that link to other LANs via telephone lines and radio waves. WANs can also use wired connections. Go through this article to find out more about WAN and Wireless WAN and how they are different from each other. What is a WAN? A WAN (Wide Area Network) is a computer network that connects multiple locations across a large geographic area, albeit it may be limited to the boundaries of a state or country. It can be ...

In a computer system, a port provides an interface to connect a peripheral device to the computer system. Thus, ports in the computer hardware are the jacks or sockets through which the peripheral devices are attached to the computer system. These ports are standardized for each purpose. There are several types of ports available in the computer system such as USB ports, Ethernet ports, display ports, serial ports, parallel ports, etc. Through these ports, we connect different hardware devices such as monitor, keyboard, mouse, etc. to the computer.

What is Registered Jack (RJ)? A Registered Jack (RJ) is a defined telecommunication network interface for connecting voice and data equipment to a local exchange carrier or long-distance carrier's service. The Universal Service Ordering Code (USOC) system of the Bell System in the United States was the first to specify registration interfaces for compliance with the registration program for customer-supplied telephone equipment mandated by the Federal Communications Commission (FCC) in the 1970s. After Bell Labs invented Registered Jack connections in 1973, they became popular. Physical construction, wiring, and signal semantics are all included in the standard. As a result, ... Read More

In asymmetric multiprocessing, all the processors are not identical and they follow a master-slave relationship; whereas in symmetric multiprocessing, all the processors are identical and they share the main memory. Read this tutorial to find out more about asymmetric and symmetric multiprocessing, and how they are different from each other. Let's start with a basic overview of asymmetric multiprocessing. What is Asymmetric Multiprocessing? Asymmetric multiprocessing is the use of two or more processors handled by one master processor. All CPUs are interconnected but are not self-scheduling. It is used to schedule specific tasks to a CPU based on priority and ... Read More

IPSec is a suite of protocols that provides security services during communications between networks. It supports network-level peer authentication, data origin authentication, data integrity, data encryption and decryption. It is often used to create a VPN.SSL is a networking protocol that provides a secure connection between a client and a server over the internet. It works at the transport layer. It is often used to secure the communication between a web browser and a web server.Read through this article to find out more about IPSec and SSL and how they are different from each other.What is IP Security (IPSec)?IPSec is ...

Bandwidth and Throughput are frequently used terms in telecommunications and sometimes we tend to use them as synonyms, but there's a subtle difference between these two terms.Bandwidth refers to the data capacity of a channel. It is defined as the total amount of data which can be transferred over a network in a specific period of time. Throughput, on the other hand, refers to the exact measurement of data transferred in a specific time period. It is also termed as "effective data rate" or "payload rate". Every network connection has a throughput, which explains how bits are transmitted across a ... Read More
