What is Public Key Encryption

vikesh145 — Wed, 04 Jan 2012 06:46:44 +0000

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

vikesh145 — Wed, 04 Jan 2012 06:25:56 +0000

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

vikesh145 — Mon, 26 Dec 2011 05:22:54 +0000

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

vikesh145 — Mon, 19 Dec 2011 11:02:35 +0000

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 In the mid of 1990s, a new architecture was introduced and was called classless addressing and eventually superseded the original architecture.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

vikesh145 — Mon, 19 Dec 2011 10:36:31 +0000

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

vikesh145 — Mon, 19 Dec 2011 07:00:16 +0000

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 Data Transfer Rate

vikesh145 — Sat, 10 Dec 2011 04:07:30 +0000

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

vikesh145 — Sat, 10 Dec 2011 03:48:03 +0000

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 Intranet

vikesh145 — Thu, 08 Dec 2011 07:42:24 +0000

Intranet is a network that is not available to the outside world of it. Intranet is the collection of private computer networks within an organization. An intranet uses network technologies as a tool to facilitate communication between people or work groups. It also helps in improving the data sharing capability and overall knowledge base of an organization’s employees. View More….

What is a Wireless Router

vikesh145 — Thu, 08 Dec 2011 05:40:56 +0000

Router is needed to link several computers together into a network. It is a type of networking equipment. These are used for interconnection among computers within the network and also allow sharing of other resources. A wireless router is a router with a wireless interface and has the utilities of a wireless access point (WAP). It act as the gateway to the internet or a local Computer network without opting for any wired connection although it works the same as wired one. It can work in a number of ways which can be a cabled LAN (local area network) or only wireless network or a combination of both. View More….
