What is Booting?

Booting

Starting a computer or a computer-embedded device is called booting. Booting takes place in two steps −

Switching on power supply
Loading operating system into computer’s main memory
Keeping all applications in a state of readiness in case needed by the user
The first program or set of instructions that run when the computer is switched on is called BIOS or Basic Input Output System. BIOS is a firmware, i.e. a piece of software permanently programmed into the hardware.




If a system is already running but needs to be restarted, it is called rebooting. Rebooting may be required if a software or hardware has been installed or system is unusually slow.

There are two types of booting −

Cold Booting − When the system is started by switching on the power supply it is called cold booting. The next step in cold booting is loading of BIOS.

Warm Booting − When the system is already running and needs to be restarted or rebooted, it is called warm booting. Warm booting is faster than cold booting because BIOS is not reloaded.

Linux Booting

Windows Booting

What is Secure Sockets Layer (SSL) and How it Works Secure Sockets Layer (SSL) is the most widely used technology for providing a secure communication between the web client and the web server. Most of us are familiar with many sites such as Gmail, Yahoo etc. using https protocol in their login pages. When we see this, we may wonder what’s the difference between http and https. In simple words, a HTTP protocol is used for standard communication between the Web server and the client. HTTPS is used for a “Secure communication”. Working of HTTP: When A sends a message to B, the message is sent as a plain text in an unencrypted manner. This is acceptable in normal situations where the messages exchanged are not confidential. But, imagine a situation where A sends a PASSWORD to B. In this case, the password is also sent as a plain text. This has a serious security problem because, if an intruder (hacker) can gain unauthorized access to the ongoing communication between Aand B , he can...
