Fast Booting by selecting HDD as First Boot Device

Booting device selection is common task for any BIOS software, where it must decide which device is used for first booting and if not available then it will search for another device. This device searching takes time and slow startup for system. But if you select booting option properly in settings you can get rid of such searching and minimize operating system loading time.

Depending on motherboard of system there are many options for booting operating system from device. These options are define in BIOS setting. Most common booting options (regardless software of BIOS) are like:-

- From Floppy Disk (too much Old), For DOS OS
- From ZIP Drive also obsolete like Floppy Disk
- From CD/DVD
- From Pen Drive/Portable HDD with USB support
- From Tape 
- From LAN
- From local HDD

Most of the case, we use local HDD for booting where OS (windows/Linux) is/are installed. But BIOS Default Setup for most of manufacturer, HDD is not first boot device. First boot device is set to removable media or Floppy drive (In old system). So, when the system starts it looking for removable device for booting and wasting time by searching OS in removable disk. But if we set HDD as first boot, then it will automatically find the HDD first and no time delay for searching removable media.

An exceptional case when we start a fresh windows setup, windows needs to boot from CD or DVD or removable media first. Because windows setup comes with removable media and if any OS exist in HDD with BIOS first priority for Hard drive booting first. It skips CD/DVD and can not start setup. In that case you need to set Removable device as first boot device and after setup you again set HDD as first boot drive.

Brief and Examples on Simplex, Half-Duplex, Full-Duplex Transmission

In data communication, there are three types of communication styles; they are Simplex, Half-Duplex and Full-Duplex. Here we discuss about their characteristics with examples. Simplex: In this communication style data can send only and basically it is one way or uni-direction communication. This type of communication is not widely used for transmit trusted data because it can not send any error or control signal to sender terminal. This style of communication is vastly used in Radio and TV where we can see and hear or receive data only but we can not send any information data by the same channel. Half-Duplex: Half-Duplex is another type of communication style where data can and send and receive but not at the same time. In this communication type, if data is send from one end, then we can not send data from another that means communication establish in one direction.  This communication vastly used in walkie-talkie, intercom, string phone etc. The practical ...
