Both Mainframe computers and Minicomputers are types of digital computers. A mainframe computer has much more features, larger memory, and high processing speed as compared to a minicomputer. Initially, mainframe computers were developed to be utilized as servers, whereas minicomputers were designed to fulfil the need of mid−sized high speed computing device. Hence, mainframe computers and minicomputers are quite different from each other. Read this article to find out more about mainframe computers and minicomputer and how they are different from each other. What is a Mainframe Computer? Mainframe computers are largesized computers having high processing speed and larger ... Read More

Computers have become an integral part of our day-to-day life. We cannot imagine our lives without computers. We use computers for almost all our daily activities. At present, everyone is familiar with digital computers like smartphones, digital watches, laptops, desktop PCs, etc. But there is another variant of computers called analog computer. Analog computers are the earlier variants of computer that are less frequently used these days or used in some specialized applications only. Read through this article to find out more about analog and digital computers and how they are different from each other. What is an ... Read More

The elementary foundation of both calculator and computer is the same because both these were developed to solve problems associated with complex calculations. At a basic level, we can state that a computer is an extended version of a calculator. A calculator can perform mathematical operations only, whereas a computer can perform various tasks like arithmetic operations, logical operations, sorting, inserting, comparison of different types of data and information and many more. In this article, we will discuss all the major differences between calculator and computer. Let's start with some basics of calculator and computer so that it will ... Read More

SOP (Sum of Product) and POS (Product of Sum) are the methods of representing a reduced logic expression. The basic difference between the two is that SOP expresses a Boolean function as a sum (logical OR) of product (logic AND) terms, while POS expresses a logic function as a product (logic AND) of sum (logic OR) terms. Read this article to learn more about SOP and POS and how they are different from each other. What is SOP? Sum of Product (SOP) is a method of representing a logic function by using minterms. The expression of a SOP includes product ... Read More

There are two types of addressing modes, namely, direct addressing mode and indirect addressing mode. In direct addressing mode, the actual address of the data is mentioned in the instructions itself. On the other hand, indirect addressing mode contains the effective address of the memory location where the actual address of the data resides. Read this article to find out more about direct and indirect addressing modes and how they are different from each other. Let's start with a basic introduction of these two types of addressing modes. What is Direct Addressing Mode? The Direct addressing mode is one that ... Read More

The primary function of a monitor and a television is almost the same, as both are used for conveying information to the outside world. The most basic difference between a monitor and a television is in their application, that is, a monitor is used as an output device in a computer system, whereas a television is a device used for entertainment like watching a video. Read this article to find out more about monitors and televisions and how they are different from each other. What is a Monitor? A Monitor is a visual display unit (VDU) used in a ... Read More

Printers and Scanners are important peripheral devices used with the computer systems, however they are absolutely different devices in terms of their function. Printers act as output devices, while scanners are input devices. Read this article to find out more about printers and scanners and how they are different from each other. What is a Printer? Printers are the most common type of output device which are used for taking a hardcopy of any digital document. It typically consists of a mechanism for transferring ink onto a paper.

A VPN connects a private network to another public network, which allows users to transmit and receive data as if their computers were connected to the private network physically.MPLS is a routing technique that is used to improve the speed and control of the network traffic. It speeds up traffic flows by avoiding complex lookups in the routing table at each node as in conventional routing algorithms.Read through this article to find out more about MPLS and VPN and how they are different from each other.What is VPN?VPN stands for virtual private networks. It is a network type that is ... Read More

There are different standards developed by different organizations to display the content over various display devices. VGA and SVGA are two such standards that are used for displaying the video data on a suitable display device. VGA supports videos and images of smaller resolution, whereas SVGA supports relatively large resolution videos and images. Read this article to find out more about VGA and SVGA standards and how they are different from each other. What is VGA? VGA stands for Video Graphics Arrays. It is a standard first developed by IBM to display video on a display screen. VGA offers high ... Read More
