Authentication | The process by which a user’s identity is checked within the |
| network to ensure that the user has access to the requested |
| resources. |
Basic In/Out System | Chips on the motherboard of a computer contain read only |
(BIOS) | memory instructions that are used to start up a computer. The |
| operating system of a PC also makes use of BIOS |
| instructions and settings to access hardware components such |
| as a disk drive. Some BIOS/CMOS settings can be set to scan |
| for viruses, causing problems for some installation programs. |
Baud Rate | The baud rate is a measure of the number of symbols |
| (characters) transmitted per unit of time. Each symbol will |
| normally consist of a number of bits, so the baud rate will |
| only be the same as the bit rate when there is one bit per |
| symbol. The term originated as a measure for the |
| transmission of telegraph characters. It has little application |
| today except in terms of modem operation. It is |
| recommended that all data rates are referred to in bps, rather |
| than baud (which is easy to misunderstand). Additionally, |
| baud rate cannot be equated to bandwidth unless the number |
| of bits per symbol is known. |
Boot | To start a computer so that it is ready to run programs for the |
| user. A PC can be booted either by turning its power on, |
| (Cold Boot) or by pressing Ctrl+Alt+Del (Warm Boot). |
Break Signal | A break signal is generated in an |
| keeping the line in zero for longer than a character time. |
| Breaks at a serial console port are interpreted by Sun servers |
| as a signal to suspend operation and switch to monitor mode. |
Checksum | A computed value which depends on the contents of a block |
| of data and which is transmitted or stored along with the data |
| in order to detect corruption of the data. The receiving system |
| recomputes the checksum based upon the received data and |
