TCP/IP is a communications protocol used to send information over the web.
Explanation:
TCP / IP, which stands for the Transmission Control Protocol / Internet Protocol, is a set of communication protocols used to connect internet network devices. The whole suite of the Internet Protocol — a set of rules and procedures — is commonly called TCP / IP.
The TCP / IP protocol suite acts as a layer of abstraction between web applications and the routing / switching fabric. TCP / IP defines how data is shared over the internet by supplying end-to-end communications that specify how the data should be split into packets, signed, distributed, routed and received at the destination.
Answer:
Option b (Port 22) seems to the appropriate choice.
Explanation:
<u>Below seem to be some measure you should take to correct this mistake.</u>
- Verify whether Droplet's host IP address seems to be right.
- Verify existing connection supports communication over all the utilized SSH port. Any access points can be able to block port 22 and sometimes customized SSH. For illustration, you could do this by checking different hosts who used the same port, using only a recognized working SSH connection. These could help you identify unless the current problem is not particular to clients' Droplet.
- Authenticate the Droplet configuration settings. Verify that they're not being configured to DROP 's preferred policy, and do not apply the port to require connectivity.
The SSH server also operates on port 22, by default.
Other choices don't apply to the specified scenario. So that the argument presented above will be appropriate.
Answer:
Signed numbers represent sign like positive or negative for a number. Unsigned numbers don't store any bit for sign
Explanation:
Signed numbers are the binary numbers where leftmost digit is used to store the sign and the remaining bits used to store the value (magnitude). if leftmost bit of binary number is 0 it is positive number and if it is 1 then it is a negative number
ex: 00110101 represents (+53)
Here 0 (leftmost) represents sign.
Unsigned number is the number which don't have any sign bit. Here only positive numbers we will represent.
ex:0110101(53)
2's complement: This is used to represent signed numbers. we will get 2's complement by inverting the bits of number and adding 1 to it
0111 1110 for 2's complement first invert the number
1000 0001 after inversion add 1 to it then we will get
010000010
