What is Public Key Encryption

Encryption is the conversion of data into a secret code which is called Cipher text that cannot be easily understood by any unauthorized person. It is one of the most effective ways to achieve data security. A file after passing through encryption process is called an encrypted file and to read this encrypted file, the user must have access to a secret key or password that enables the user to decrypt it. (Decryption is the process of converting encrypted data back into its original form, so it can be understood). The simple or unencrypted data is called plain text. View More....

What is Object Code in a Computer Program

A Program in Computer consists of two; first is the source code, other is the Object Code. Source code is the version of a computer program as it is originally written i.e. typed into a computer by a programmer in a programming language. A compiler is a specialized program that converts source code into object code and it converts the whole program at a time. The object code is a machine code, also called a machine language, which can be understood directly by a specific type of CPU (central processing unit). View More...

What is Mbps

Mbps stands for Mega Bits per second (means millions of bits per second). It is used to state the number of bits of data that can flow through a network connection or can be used to represent the bandwidth (bandwidth means total amount of data flow over a given time period) of a network connection on a telecommunication medium. It states the number of bits of data that can flow through a network connection. View More....

What is IP or Internet Protocol

Internet Protocol is an address of a Computer on a network. An IP address is a 32 bit address. The IP addresses are unique i.e. no two Computers, connected to the internet can have same IP addresses. IP addresses when started used the concept of classes. This architecture is called class-full addressing. In the mid of 1990s, a new architecture was introduced and was called classless addressing and eventually superseded the original architecture. However, part of the Internet is still using class-full addressing, but the migration is very fast. In classless addressing variable-length blocks are assigned that belong to no class. In this architecture, the entire address space (232 or 4,294,967,296 addresses) is divided into blocks of different sizes. Class-full addressing is a special case of classless addressing.

What is Internet Bandwidth

Bandwidth is basically the amount of data actually transferred over a fixed period of time between a Computer and the internet. It is often measured in KB (Kilo Byte) or GB (Gega Byte). An Internet Service provider always sells the plans based upon the speeds, and hence limits bandwidth to certain extent according to the plans. The more the bandwidth the service provider will be providing, more the rate or price of the plan will be and faster the connection will be. View More....

What is DWDM

DWDM stands for Dense Wavelength Division Multiplexing. DWDM is a technology used to increase the capacity of Fiber Optics that results in faster transfers of data. As the Fiber optics are very thin and small fibers that are used to transmit data and light throughout a Computer and network that’s why increasing its capacity is very beneficial. View More.....

What is Dual Core Technology

Dual core technology is basically putting two processors on a single chip. Dual Core Processor is between a single core processor and a dual processor system for architecture. Dual core technology has two processors but it does not mean that it will be providing double performance in all the areas to the user. It has two cores but shares some of the hardware like the memory controller and bus while a dual processor system has completely separate hardware and shares nothing with the other processor.

What is Data Transfer Rate

Data Transfer Rate is the rate at which data can be transmitted from one device to another. Data Rate is basically commonly used to measure how fast data is transferred from one location to another. Data Rates are often measured in megabits (Mbps) or megabytes (Mbps) per second. (‘b’ in Mbps means bits and ‘B’ in MBps means bytes). This rate is basically compared to flow of traffic. Data transfer rate is subject to problems as well. It is the amount of data per unit time which can move across input output bus when executing an input output load. View More....

What is BCC

BCC stands for Blind Carbon Copy. BCC is used in sending emails. The main feature of BCC is that it sends Email to multiple recipients without disclosing the individual emails addresses. When a person sends same email to a number of recipients, then it is the usual practice of the customer to send it in To: field by using comma or semi colon. But when the email is sent in this way, each receiver is able to see the complete list of recipient email addresses to which the same message is being sent to. BCC option allows hiding recipients in email messages i.e. the receiver will not be able to see the list of recipient email addresses. Thus using BCC is a smart way to protect the privacy of the recipients. View More....

What is an Extranet

Extranet is a communication tool designed to enable easy information sharing within the work-groups. Extranet is basically a Computer network that allows controlled access from the outside for specific business or educational purposes. It is actually an Intranet that is partially accessible to authorized outsiders. View More.....
