A printer is an output device that produces information or computer outputs on a paper. Depending upon the technology used, printers are classified into two categories namely, Impact Printers and Non-Impact Printers. An impact printer is one that operates by striking a printing head (made up of metal or plastic) against an ink ribbon, whereas a non-impact printer is one that prints characters and graphics without direct physical contact between the printing head and the paper. Read this tutorial to find out more about Impact and Non-impact Printers and how they are different from each other. What is an Impact ... Read More

The primary difference between holography and photography is that holography is a technology used to create three-dimensional (3D) images of an object, whereas photography is one that creates two-dimensional (2D) images of a three-dimensional object. Read this tutorial to find out more about Holography and Photography and how they are different from each other. What is Holography? Holography is a technique to generate 3-dimensional images using interference and diffraction of light. It uses a coherent and monochromatic source of light. A hologram is needed to regenerate an image. In other words, holography can be defined as the process of wave ... 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 ...

EIGRP stands for Enhanced Interior Gateway Routing Protocol. It is used to share information between routers lying in the same region. It can be easily implemented in small as well as large networks.OSPF stands for Open Shortest Path first. It is used on variable-length subnet masking (VLSM) and discontinuous networks. It is a classless routing protocol.Read through this article to find out more about EIGRP and OSPF and how these two protocols are different from each other.What is EIGRP?EIGRP is an advanced distance-vector routing protocol for automating routing decisions and configuration on a computer network. Cisco Systems designed the protocol ... Read More

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

When a user presses the power button on their computer, it initiates the process known as "booting, " which loads and starts the operating system. Booting can also be thought of as a series of actions where the ROM of the computer is accessed in order to load the startup instructions. After that, the operating system is loaded from the disc that is now being used to boot the computer.A primary option for the boot disc is frequently the local hard drive. The process of booting the computer is finished when the operating system is loaded; at this point, the ... Read More

Spoofing is an identity theft where a person tries to use the identity of a legitimate user. Phishing, on the other hand, is a phenomenon where an attacker employs social engineering methods to steal sensitive and confidential information from a user. Spoofing and phishing are both forms of cyber-attacks aimed at tricking you into disclosing your personal information. Both methods will be used by a criminal to gain your user names, passwords, and maybe more. Despite the fact that their final aim is the same, their techniques are not.

In a computer system, several types of secondary storage devices like HDD, CD, DVD, etc. are used to store permanent data and information. These devices can be categorized into two types namely – magnetic memory and optical memory. A magnetic memory like HDD consists of circular disks made up of non-magnetic materials and coated with a thin layer of magnetic material in which data is stored. On the other hand, optical disks are made up of plastic and consist of layers of photo-sensitive materials in which the data is stored using optical effects. A major advantage of the magnetic disk ... Read More

SEO and SEM both are the techniques to increase the visibility and traffic on a website, however both are quite different from each other. The most basic difference between the two is that SEO focuses on enhancing the organic traffic on a website, while SEM uses different strategies to increase traffic like SEO, paid promotion, etc. Read this article to learn more about SEO and SEM and how they are different from each other. What is Search Engine Optimization (SEO)? Search Engine Optimization (SEO) is a way to increase the visibility of a website by nonpaid forms of advertising. It ... Read More

Channel allocation techniques are used in radio resource management for wireless and cellular networks to distribute bandwidth and communication channels to base stations, access points, and terminal devices.The objective of channel allocation is to maximize system spectral efficiency in bits/s/Hz/site through frequency reuse while maintaining a high level of service by minimizing co-channel and neighboring channel interference among neighboring cells or networks that share the bandwidth.Channel allocation techniques can be grouped into two categories: Fixed Channel Allocation and Dynamic Channel Allocation.Read through this article to find out how these two channel allocation techniques are different from each other.What is Fixed ...
