Input Devices

Input devices are the hardware parts of the computer that is used to provide input to the processing unit. Input can be either the data or the control signal that is required for the execution of the particular process. Evolution of Input Devices Input devices have evolved over years, earlier the input devices used to […]

Data Mining

Data mining is a technique to turn raw data collected by a company, enterprise, or organization over years into useful information. Just as we mine gold from sand or rocks in a similar way, we mine information from the collected data that can be used for the benefit of the company. Data Mining: What is […]

Analog and Digital

Analog and digital are the terms that we often referred with data and signals. In today’s discussion we will be talking about both analog and digital data, and analog and digital signals. If we say that there is a sender who has some data to be transmitted to the receiver. But the data that is […]

Parallel Computer

A parallel computer is a kind of computer structure where a large complex problem is broken into multiple small problems which are then executed simultaneously by several processors. We often consider this as parallel processing. When it comes to the structure of parallel computers it can be characterized with the help of features such as […]

Information Lifecycle

Information lifecycle defines the changing value of information over a period of time. The value of information varies with time as the information that is valuable today may not be equally important tomorrow. Or the information that is of no use today may become more important tomorrow. Today we will discuss about the entire lifecycle […]

Data Center Infrastructure

Data center infrastructure is the hardware resources that are used to store and manage a large amount of data. It includes computers, storage systems, networking hardware, power backups, and also the systems to regulate the environment such as air conditioners and fire suppression. Nowadays the big organization does not store data in one system instead […]

Information Storage

Information storage is a process of collecting, organizing, and storing the data into a data repository in a digital form, from where the data can be access to derive the information for business use. In this section, ahead we will discuss information storage right from the collection of raw data, how it is structured to […]

Geostationary Satellite

A geostationary satellite is one of the communication satellites that creates the communication channel between the sender and receiver present at different locations on the earth. This satellite appears stationary as if it is fixed in the sky. Geostationary Satellite Definition A geostationary satellite is a satellite that appears stationary when we observe them from […]

Flow Control in Data Link Layer

Flow control in the data link layer is a technique that controls the rate of data transmission between the sender and receiver. If the sender is on a fast and powerful computer as compared to the receiver then the receiver may get overwhelmed by the frames transmitted by the sender. In such a scenario even […]

Performance of a Network

The performance of a network is an important issue in every network. To determine the performance of a network there are various parameters such as how efficient a network is, is the network reliable, the speed of data transmission, is the network secure, etc. Here we will discuss the terms which are used to decide […]
