Module 1 Flashcards
What are the four major PC components for personal computers?
Motherboard
Hard Drive
RAM
BIOS/CMOS
What are the 8 main motherboard components?
CPU socket
PCI bus expansion slot
PCI-Express expansion slots
RAM slots
Chipset with heat sinks
SATA connectors
IDE connector
Main power connector
Where is the CPU installed?
CPU socket
Used to add functionality to a PC by adding expansion cards that have a Peripheral Component Interconnect (PCI) connector?
PCI bus expansion slots
Slots for installing RAM on the motherboard?
RAM Slots
The chipset consists of two chips referred to as the Northbridge and the Southbridge.
Chipset with heat sinks
Where are heat sinks located and why?
Heat sinks sit on top of the chipset to prevent it from overheating.
This connector is used for connecting hard drives and CD/DVD drives that use Serial AT Attachment specification.
SATA Connectors
This is a collection of wires carrying data from one place to another on the computer?
A bus
What is the primary long-term storage component in a computer?
Hard drive
Hard drives consist of magnetic disks called?
Platters
What do platters store and in the form as?
Platters store data in the form of magnetic pulses.
Are magnetic pulses maintained when power is turned off in hard drives?
Yes, magnetic pulses are maintained.
Each magnetic pulse of a hard drive represents?
A single bit of data.
Two or more computers connected by some kind of transmission medium, such as a cable or air waves.
Computer Network
If you want to network a stand-alone computer, what components required?
Network interface card (NIC) - an add-on card that is plugged into motherboard expansion slot, provides connection between computer and network.
Network medium - cable that plugs into NIC and makes connection between computer and network. Network media can also be air waves, such as wireless networks.
Interconnecting device - Switches, hubs, routers, and wireless access points.
What are the categories of Network software?
- Network clients and servers
- Protocols
- NIC driver
Explain the Network client and servers category of Network software.
Network client software requests information that’s stored on another network computer or device.
Network Server software allows a computer to share its resources by fielding resource requests generated by network clients.
Explain the protocols category of Network software.
Network protocols define the rules and formats a computer must use when sending information across the network.
Comparing to human languages. In order for to people to communicate effectively they must speak the same language. So two computers that want must use the same protocol.
Example of network protocol is TCP/IP.
Explain the NIC device driver of Network software.
NIC device driver is also known as “NIC driver”.
After a network protocol has formatted a message correctly, it hands the data off to the NIC driver for transmission onto the network.
NIC drivers receive data from protocols then forward the data to the physical NIC that transmits data onto a medium.
The reverse is also true, if receiving data to NIC from medium, NIC hands off to NIC driver then hands off to network protocols.
