1. Bridge is a network device.
2. Bridge is a Data Link Layer Device.
3. Bridge is a two port device
4. Bridge used to interconnect two LAN's working on same protocol.
5. Bridge is an Intra-Networking device
6. Bridge can read and store MAC address.
7. Bridge is like a repeater with additional functionality that it can read MAC address
Types of Bridge:
1. Transparent Bridge:
Stations /PC's are unaware from the existence of bridge.
2. Source Routing Bridge:
Source station perform rounting operation and data send to specific route. Both stations ( sender and receiver) are aware of existence of the bridge.
1. Hub is a network device
2. Hub is a Physical Layer device.
3. Hub is a multiport device.
4. Signal travel in the form of bits in Hub.
5. Hub support electric signal
6. Hub is a half duplex device
7. Hub is an unintelligent device
8. Hub does not learn or store MAC address
9. Collision occurs commonly in Hub
10. Hub support only single collision dimension
11. Hub does not support Advanced features like VLAN, STP, RSTP etc.
Types of Hub:
1. Active Hub
Which hub have own power supply is called active hub.
2. Passive Hub
Which hub used Active hub power supply is called passive hub.
A storage device is a kind of hardware, which is also known
as storage, storage medium, digital storage, or storage media that has the
ability to store information either temporarily or permanently.
Two types of storage devices, primary and secondary
Primary storage
devices: They
are fit internally to the computer and very fast in terms of accessing data
files. The RAM and cache memory are the examples of the
primary storage devices.
Secondary storage
devices: The
hard disk, USB storage devices and optical disk drive are examples of
secondary storage devices, which are designed to store data permanently. They
include a large storage capacity while comparing with primary storage devices.
Examples of storage
devices:
Magnetic
storage devices
Floppy diskette
Hard drive
Magnetic Card
SuperDisk
Tape cassette
Zip diskette
Optical
storage devices
Blu-ray disc
CD-ROM disc
CD-R and CD-RW disc.
DVD-R, DVD+RW, DVD+R, and DVD-RW disc.
Flash memory
devices
Flash drive
Memory card
SDHC card
SSD
SD Card
Any
peripheral that accepts data from a computer and prints, projects, or
reproduces it is known as an output device.
The output
may be audio, video, hard copy – printed paper, etc. Output devices convert the
computer data to human understandable form.
Output Devices
1. Monitor
2. Printer
3. Plotter
4. Projector
5. Speakers
6. Headphones
7. Sound Card
8. Video Card
9. Speech synthesizer
10. GPS
