OK, so who’srepparttar boss…? BIOS, CMOS or POST? If we must choose, it would berepparttar 107796 (Power-on, Self-test), POST. The POST is simplyrepparttar 107797 process ofrepparttar 107798 BIOS usingrepparttar 107799 information from CMOS to startrepparttar 107800 computer. Remember,repparttar 107801 BIOS information is stored in CMOS memory maintained by an onboard battery.

Three ways to change and/or updaterepparttar 107802 BIOS. Unlike ROM (read-only memory)repparttar 107803 EPROM BIOS can be changed or updated. The term for changingrepparttar 107804 EPROM software is referred to as flashing. You may have over heard someone say that they need to flashrepparttar 107805 BIOS with a new update. Don’t worry if you have never heard this, well, maybe you should worry a little. Computer components change on a daily basis andrepparttar 107806 BIOS needs to be flexible enough to be able to change with them. All computers allowrepparttar 107807 user to changerepparttar 107808 BIOS software and how repparttar 107809 computer reacts to input/output devices. The standard is to offerrepparttar 107810 user a way in torepparttar 107811 software via a hotkey at startup. Normally this hotkey isrepparttar 107812 F2 key,repparttar 107813 Del (Delete) key and in some casesrepparttar 107814 F1 key or a combination of keys. Start your computer and watchrepparttar 107815 bottom left corner onrepparttar 107816 screen. This should let you know which key to press to enterrepparttar 107817 BIOS setup. The BIOS setup, sometimes calledrepparttar 107818 CMOS setup, allowrepparttar 107819 user to make changes onrepparttar 107820 fly and save them. Let’s say you added an external modem to your PC on Communication serial port number 1(Comm1), and no matter how many times you installrepparttar 107821 drivers, you can’t getrepparttar 107822 PC or Windows to recognize it. Chances are thatrepparttar 107823 BIOS does not know thatrepparttar 107824 modem exists. Enteringrepparttar 107825 BIOS setup and changing it to allowrepparttar 107826 use of Comm1 will fixrepparttar 107827 problem and letrepparttar 107828 PC know that a device exists on that port. This isrepparttar 107829 most common use ofrepparttar 107830 BIOS setup and alsorepparttar 107831 easiest to do. WARNING: it is just as easy to totally screw up your system by making changes inrepparttar 107832 BIOS setup. So be careful and make sure you know how and what to change. Changingrepparttar 107833 wrong settings can render your computer useless. There, we warned you twice, that’s because we want you to think twice before you changerepparttar 107834 BIOS. Second isrepparttar 107835 Flash BIOS update fromrepparttar 107836 manufacturer ofrepparttar 107837 BIOS. This is a software program thatrepparttar 107838 manufacturer ofrepparttar 107839 BIOS sends out periodically to insurerepparttar 107840 BIOS conform to new equipment and standards. You can normally get this software upgrade forrepparttar 107841 manufacturer and sometimes fromrepparttar 107842 motherboard manufacturer. Be careful…be very careful installingrepparttar 107843 software and be positive that it is for your specific BIOS. Always followrepparttar 107844 manufacturers instructions exactly. The third way is replacingrepparttar 107845 BIOS chip. Replacingrepparttar 107846 chip may be your only recourse and should be left to professional computer repairmen.

How do I know which BIOS I have? That also easy,repparttar 107847 computer will actually tell you. If you’re fast enough, you will seerepparttar 107848 BIOS name and version onrepparttar 107849 screenrepparttar 107850 moment you turn it on. If you are not a speed-reader you can accessrepparttar 107851 BIOS setup and retrieverepparttar 107852 information fromrepparttar 107853 setup program. You may also contactrepparttar 107854 motherboard manufacturer and find which BIOS was installed on that board.

As stated earlier,repparttar 107855 beeps mean something. They can give you information on problems thatrepparttar 107856 BIOS encounters. Contact your BIOS manufacturer to find out what each beep series means. Armed with this information you may be able to figure out why your PC has stopped working and avoid scratching your head and noticing this huge question mark hovering over your PC.

repparttar Internet for communicating withrepparttar 107795 outside world, for gathering information, and for doing business. It didn't take long for people to recognize thatrepparttar 107796 components that worked so well onrepparttar 107797 Internet could be equally valuable internally and that is why intranets are becoming so popular. Some corporations do not have TCP/IP networks,repparttar 107798 protocol required to accessrepparttar 107799 resources ofrepparttar 107800 Internet. Creating an intranet in which allrepparttar 107801 information and resources can be used seamlessly has many benefits. TCP/IP-based networks make it easy for people to accessrepparttar 107802 network remotely, such as from home or while traveling. Dialing into an intranet in this way is much like connecting torepparttar 107803 Internet, except that you're connecting to a private network instead of to a public Internet provider. Interoperability between networks is another substantial bonus. Security systems separate an intranet fromrepparttar 107804 Internet. A company's intranet is protected by firewalls-hardware and software combinations that allow only certain people to accessrepparttar 107805 intranet for specific purposes.
