There are six basic functions of IT.
1. Capture: Compiling detailed records of activities.
2. Processing: Converting, analyzing, computing and synthesizing all forms of data and information.
3. Generation: Organizing information into a useful form.
4. Storage: Retaining information for further use.
5. Retrieval: Locating and copying stored data or information for further processing or for transmission to another user.
6. Transmission: Distributing information over a communication network.
Answer: (C) MAC
Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
On the other hand, all the options are incorrect as they are not the key dependent hash function.
Therefore, Option (C) is correct.
Answer:
A. The proposed solution delivers the required result and both optional desired results.
Explanation:
The IEEE 802.11a is the standard code of the wireless communication technology known as WIFI, it is wireless as it requires no cable to connect to a network device. The data transmission rate of the IEEE 802.11a is 1.5 - 54Mbps (mega bit per second). So, the employees in the TVBCA building can wireless connect to the network, which allows them to be mobile and they can also send large CAD files among themselves.
