Graphic designing requires art skills.
Answer:
C. receiving data.
Explanation:
An information system interacts with its environment by receiving data in its raw forms and information in a usable format.
Information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.
Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.
Additionally, an information system comprises of five (5) main components;
1. Hardware.
2. Software.
3. Database.
4. Human resources.
5. Telecommunications.
<em>Hence, the information system relies on the data it receives from its environment, processes this data into formats that are usable by the end users. </em>
Answer:
A. 31 bits
B. 13 bits, 18 bits
C. 256k
Explanation:
A.
We have total size of physical memory as 2gb
This means that 2¹ x 2³⁰
Using the law of indices,
= 2³¹
So physical address is equal to 31 bits
B.
We get page size = 8kb = 2³
1 kb = 2¹⁰
2³ * 2¹⁰ = 2¹³
So page replacement = 13 bits
Page frame number
= physical address - replacement bits
= 31 - 13
= 18 bits
C.
The number of frames is given as
2¹⁸ = 2⁸ x 2¹⁰ = 256K
So number of frames = 256K
D
Logical add space is 256K
Page size= physical pages = 8kb
Logical address layout= 28biys
Page number = 15 bits
Displacement = 12 bits
256k/8k = 32 pages in address space process
Answer:
The correct answer is PGP i.e "Pretty Good Privacy" .
Explanation:
Pretty Good Privacy is an encryption algorithm that gives the database interaction with the confidentiality and authorization.Pretty Good Privacy is security algorithm which gives the security into the mail . login ,decryption ,encryption are the example of the "Pretty Good Privacy" .
Pretty Good Privacy is a type of hybrid cryptosystem that incorporates cryptographic algorithms and it has de facto open source standard for the mail and the file storage .
