Answer:
Scaling changes the size of the whole image by resampling it(duplicating the pixels). in cropping you only get a part of the original image/ remove the outer area of it .
Explanation:
Answer:
7 raise to power 10
Explanation:
Since there are 4 possible ways to make memory chip and 3 possible ways to manufacture mother board, so for each machines we have 7 possible ways of configurations.
So total number of ways in which these machines can be configured is 7*7*7*...*7= 7raise to power 10 possible ways
Answer:
Option (C) FAT32 File System Type
Explanation:
- FAT32 File System Type cannot be encrypted by the accounting users.
- FAT stands for File Allocation Table. It is a file system architecture.
- The File Allocation Table is an index table which contains the details about each cluster ( disk storage space ).
- By traversing the File Allocation Table, the operating system gets the details the file ( where it is located ) and the size of the file.
- The FAT32 file system contains more number of possible clusters.
- In this system, 32 bits are used to store the total number of possible clusters.
- In FAT32 file system, the transparent encryption is not supported.
- So, option (C) is correct.
- All other options are wrong options.
Answer:
All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.
A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision
Explanation:
Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.
CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.
