Answer:
True.
Explanation:
OSI network model is a networking framework that has seven layers that describes the encapsulation and communication of devices in a network. The seven OSI model layers are, application, presentation, session, transport, network, data-link and physical layer.
Each layer in this model describes the protocol datagram unit PDU and identifies several standard and proprietary protocols that can be used in a layer.
A network administrator of engineer can decide to use a protocol based on his choice and the brand of network device used.
Answer:
Lightweight directory access protocol (LDAP)
Explanation:
Lightweight directory access protocol is a protocol that provides a common open protocol for interfacing and querying a directory service information given by a network operating system. LDAP is an application layer protocol that uses port number 389 via tcp and udp. LDAP queries are transmitted in text and allows for all or some data be queried anonymously.
Lightweight directory access protocol, ordinarily does not require user authentication connection, but this can be configured to ask for user credentials.
Answer:
The ledgers are secure, shared, and incorruptible is the correct answer.
Answer:
a. 6 bits
b. 1
Explanation:
Ans (a)
40 Characters need to be represent by binary coded Zebronian (BCZ) , So You will need 6 bits.
5 bits wold only give you 32 = 2 x 2 x 2 x 2 x 2 unique characters.
So 6 bits would allow you to represent 64 characters.
Ans(b)
BCD = Binrary Coded Decimal is very common in electronics, particularly it displays numerical data.
BCD Encodes each digit of a decimal number into 4 digit binary form.
Each decimal digit is indiviidually converted to oits binary equivalent
For Example : 146 , the decimal degits are replaced by 0001 , 0100 and 0110 respectively
Addition
1 0 = 10 is binary value of 2 2
+1 1 = 11 is binary value of 3 + 3
---------- -----------
1 0 1 5 Ans
Subtraction
1 1= binary value of 3 3
- 1 0 = binary value of 2 - 2
--------- -----------
0 1 1 Ans
