What is Malware

A Malware is malicious (with harmful intent) software or a program (which can be any code, scripts etc…). A Malware can result in leaking the information of the user’s system or can track each and every activity which is being performed on the web Browser or can redirect the control to some UN-advisable web sites. These are usually poorly programmed and can cause the user’s Computer to respond really slowly as compared to its actual speed. View More....

What is Ethernet

Ethernet is a physical and data link layer used for local area networks (LAN's). Ethernet was invented by engineer Robert Metcalfe​.

What is 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 andto 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 unencrypted data is called plain text. View More....

What Is Defragmenting a Computer

De-fragmentation (also known as ‘def-rag’) is a process that reduces the amount of fragmentation in file system i.e. it re-arranges the files on the disk. Fragmentation happens to a hard drive over a period of time as the user continues to change, save or delete files. These changes are often stored at a location on the hard disk that is different from the original file and so the additional changes are. Both the file and the hard disk itself become fragmented, and results in slowing down of Computer as it has to look in many different places to open a file. View More...

What is Computer Hacking

A hacker must be able to exploit a weakness or vulnerability (i.e. loop holes in the system by which the computer can be affected) in a computer system. View More....

What is an Encryption Key

An Encryption key is used to perform encryption. Encryption is the process of transforming information into unreadable code with the help of cipher (a kind of Algorithm) that any unauthorized user cannot understand. A key is basically a string of digits. Encryption key can act as a password when a user tries to connect to a wireless network. This key is then called WEP (Wired Equivalent Privacy) key which is just encryption key. It acts as a security measure and provides security for the network by allowing only authorized persons to connect. Decryption (which is opposite of encryption) uses a decryption key. View More...

What is MHz

MHz stands for Megahertz. Megahertz is an enhancement of hertz only. The term hertz was named on Heinrich Rudolf Hertz​ (contributed to study of electromagnetism). The abbreviations are written as Hz and MHz (i.e. mentioned in capitals) for the terms hertz and megahertz. The term megahertz itself can be broken into two terms i.e. ‘mega’ and ‘hertz’ which mean ‘million’ and ‘cycles’ respectively. Hertz is basically a unit which is used to measure frequency when a person is using the International System of Units. While the term megahertz acts an extension to the term hertz only, actually megahertz means (or is equal to) 1 million hertz where hertz were considered as cycles. So the term megahertz means 1 million cycles per second. View More...

What is L2 Cache

Cache Memory acts as a high speed buffer between the RAM and CPU. Cache RAM operates at higher clock frequencies than normal RAM. This allows the data to be read more quickly from the cache than the main memory.Cache memory functions as a “near store” of RAM i.e. these are the stores which the CPU can always be supplied from. There are at least two close stores which are called Level 1, Level 2 cache (Level 3 cache is also sometimes there e.g. in Intel Itanium processors, Level 3 cache is there). The cache memory ensures that data is constantly fetched from the RAM so that CPU does not sit idle. View More....

What Is a WAN Port

A Wan port is the Portal (Web portals provide users with functionality such as search and navigation capabilities and information management) by which information passes back and forth between the Lan and the WAN.
