2. Temporary storage 3. Electrical system 4. For communication with other devices 5. Programming and setup data |
|
|
What are the processing components of motherboards?
|
CPU and Chip set
|
|
|
What are the temporary storage mediums of motherboards?
|
RAM and Cache Memory
|
|
|
What is the component of the electrical system of motherboards?
|
Power supply connections
|
|
|
What are the components of communication with other devices of motherboards?
|
Traces, Expansion slots, and System clock
|
|
|
What are the components of programming and setup data of motherboards?
|
Flash ROM and CMOS setup chip
|
|
|
What are the two functions of the chip set?
|
1. Controls flow of data and instructions to and from the CPU
2. Provides careful timing of activities |
|
|
What are the two types of storage devices?
|
1. Temporary (primary storage, or memory)
2. Permanent (secondary storage) |
|
|
What are the two characteristics of temporary storage?
|
1. Temporarily holds data and instructions while processing them
2. Faster to access than permanent storage |
|
|
What is one characteristic of permanent storage?
|

|
|
|
List two (or more) secondary storage devices.
|
1. Hard disks
2. Floppy disks 3. Zip drives 4. CD-ROMs 5. DVDs |
|
|
What are the two functions of the system clock
|
1. Synchronizes the activity
2. Sends continuous pulses over the bus that are used by different components to control the pace of activity |
|
|
What is the frequency of the activity of the system clock measured in?
|
MHz (1 million cycles per second)
|
|
|
List three physical network architectures.
|
Ethernet, Token ring, and wireless LAN
|
|
|
List three variations of network speed.
|
10-Mbps Ethernet, 100-Mbps Ethernet (Fast Ethernet), 1000-Mbps Ethernet (Gigabit Ethernet)
|
|
|
List one advantage and one disadvantage of bus and star topology.
|
Bus topology connects each node in a line but there is no centralized point of connection. Star topology connects all nodes in a lime and is more popular
|
|
|
Please describe the characteristics of a repeater.
|
A repeater restores the clarity of a signal. When a signal travels over a long distance, it starts to degrade, but a repeater prevents that degradation and allows the signal to reach its destination in good quality
|
|
|
List three characteristics of token ring networks.
|
1. Relies on tokens
2. The speed is 4Mbps to 16 Mbps 3. Uses a centralized device called a Multistation Access Unit (MAU) |
|
|
List three characteristics of a wireless LAN.
|
1. Requires wireless NICs
2. Can be used in combination with wired LAN 3. Security is an issue |
|
|
List three components needed to connect a PC to a network
|
1. NIC card
2. Network cable (patch cable) 3. A device to connect the PC to (e.g., hub) |
|
|
How do NIC cards work?
|
1. Manages communication and hardware protocols for the PC
2. Sends and receives data to and from system bus in parallel 3. Sends and receives data to and from network in series |
|
|
List three characteristics of troubleshooting a network.
|
1. Check for an IRQ conflict
2. Check cabling and ports 3. Make sure NIC and its drivers are installed |
