|
What is the voltage output of an AT power supply?
|
12V and 5V to the motherboard. Additional regulators are needed on the motherboard if 3.3V cards (ie PCI cards) or processors are used.
|
|
|
List the features of an LPX motherboard.
|
- LPX stands for Low Profile Extensions
- this form factor was developed for a slimmer desktop -This design uses a riser card that extends from the motherboard and allows expansion cards to be installed parallel to the motherboard. |
|

What are the advantages of ATX motherboard form factor over the Baby AT?
|
- Intergrated I/O ports, baby AT has a cable connecting the motherboard to the I/O ports
- ATX uses a 20-pin plastic power supply connector called a keyed connector which can only be plugged in one way. Babe AT motherboards use a pair of 6-pin connectors - ATX motherboards have intergrated PS2 connectors, most baby AT do not have a PS2 mouse port - ATX motherboard support 3.3V at the power supply, which is used by newer processors - ATX motherboards support "soft switch" which allow power management utilities to shutdown the computer - With ATX the processor is moved closer to the power supply providing it with better air circulation and cooling |

|
|
|
Do AT and mini AT motherboards use jumpers of DIP switches to configure on-board settings?
|
DIP switches
|
|
|
What is current?
|
Current is the amount of electricity moving across a wire. Current is measured in milliamperes or amperes (amps).
|
|
|
Define resistance.
|
Resistance is a measure of how much an object resists or holds back the flow of current. When electrical resistance is increased, the amount of current is decreased. Resistance is measured in ohms.
|
|
|
Defile voltage.
|
Voltage is a measure of pressure on electrons as they are being pushed through a medium. Voltage is measured in volts.
|
|
|
Defile wattage.
|
Wattage is the amount of work that electrical current is capable of performing. Wattage is measured in watts.
|
|
|
Describe the connectors coming from an AT power supply.
|
AT style motherboard use P8 and P9 Molex type connectors. These connectors plug into the motherboard side-by-side. The black ground wires must be kept next to each other.
|
|
|
If a computer continuously reboots on its one it could be a sign that...
|
it might not be receiving enough power from its power supply. Check it with a digital multimeter.
|
|
|
How are the voltages on the wires of a typical power supply color coded?
|
red = +5V
white = -5V yellow = +12V blue = -12V black = 0V (ground) |
|
|
What is electrostatic discharge (ESD)?
|
ESD is a phenomenon that occurs when electricity builds up (usually in a persons body) and is passed onto a computer and components. ESD wrist strap, which contains a resistor, should be used when handling components inside a computer system.
|
|
|
Should ESD wrist straps be worn when working on a monitor?
|
No, monitors store high levels (about 15,000 volts) of voltage which can cause serious bodily harm when interacting with the resistor in a wrist strap.
|
|
|
What doees CMOS stand for?
A) Conductive Metal Oxide Source B) Continuous Memory Off Systemboard C) Complementary Metal Oxide Semiconductor D) Contiguous Memory Operating System |
C) Complementary Metal Oxide Semiconductor
|
|
|
If a CMOS battery begins to lose its charge it might...
|
display a CMOS checksum error when the computer is turned on. Checksum error my also indicate that the BIOS may need to be upgraded.
|
|
|
If a CMOS batter loses its charge completely...
|
some or all of your BIOS settings may be lost including date and time, hard drive, and system password.
|
|
|
What is PGA?
|
The pin grid array or PGA is a type of packaging used for integrated circuits, particularly microprocessors. The underside of a PGA package looks like a "bed of nails." In a staggered PGA (SPGA), the pins do not line up in perfect rows and columns.
|
|
|
What is SIMM?
|
A SIMM, or single in-line memory module, is a type of memory module used for random access memory in personal computers. It differs from a DIMM (the most predominant form of memory module today) in that the contacts on a SIMM are redundant on both sides of the module.
The earliest SIMM sockets were conventional push-type sockets. These were soon replaced by ZIF (Zero Insertion Force) sockets in which the SIMM was inserted and rotated until it locked into place. To install a SIMM, the module must be placed in the socket at an angle, then rotated (angled) into position. To remove one, the two metal or plastic clips at each end must be pulled to the side, then the SIMM must be tilted back and pulled out. The earlier sockets used plastic retainer clips which were found to break, so steel clips replaced them. |

|
The CPU performs what function(s) in a personal computer?
A) The central processing unit performs all the calculation that take place inside a pc. B) The central processing unit provides a central repository for system information. C) The central power unit provides DC electricity for the motherboard and devices inside a pc. D) The Celeron Pentium unit stores programs used by the microprocessor. |
A) The central processing unit handles all the mathematical calculations that make a personal computer function.

What is SEC?
|
SEC or Single Edge Cartridge is a CPU package that was adopted by Intel starting with the Pentium II. Intel abandoned the PGA or Pin Grid Array for this design. Celeron, Pentium II, and III's use this design
The SEC cartridge snaps into a special slot on the motherboard called Slot 1. AMD had a similar design which was called Slot A. |
|
|
What CPU first introduced multiprocessor support?
|
The Intel 80386.
|
|
|
Does SRAM require a refresh?
|
No. SRAM or Static Random Access Memory uses a special circuit called a flip-flop which does not use capacitors (DRAM uses capacitors) and therefore does not require a refresh. SRAM is faster but is much more expensive than DRAM.
|
|
|
What is RAM cache?
|
A small internal cache found in Pentium CPU's. It stores a backlog of commands so that when the CPU encounters a wait state the CPU does not have to stop; it simply processes commands stored in cache.
|
|
|
What is the FSB and what are its components?
|
The Front Side Bus or system bus is the physical bi-directional data bus that carries all electronic signal information between the CPU and other devices within the system such as RAM, AGP video cards, PCI cards, hard disk, etc.
The Frontside Bus consists of the CPU, Northbridge, RAM, address bus, and external data bus. |
|
|
What is the backside bus?
|
The backside bus is the data connection between the CPU and L2 cache.
