Answer:
Switches break up collision domains and routers break up broadcast domains.
Explanation:
- Collision domain depicts the part within a network where a collision can happen.
- Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
- Too many collisions can result in slow traffic speed and can effect network performance.
- So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
- When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
- Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.
- Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
- Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
- Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
The
answer is FALSE because the
interior of commercial Hard disk drive is with stack of magnetic disks
(platters) containing the user’s data and a rotating arm supporting the magnetic
heads. The rotating arm is moved by the torque generated by a voice coil motor
(VCM) mounted at one end of the arm. Data read/write operations rely on the capability of the
governing unit of the HDD to maintain the magnetic read/write heads as close as
possible to center of the desired track. Typically, reliability of data reading
and writing is guaranteed when the head is kept within 5% of the track pitch
from the track center. This means that the accuracy required for the head positioning
is in the range of a few tens of nanometers.
