the answer is Arithmetic Exception error
Im going to go with D on this one but dont rely on my answer this is just a educated guess
Answer:
A(n) <u>Cipher</u> or crypto-system is an encryption method or process encompassing the algorithm, key(s) or crypto-variable(s), and procedures used to perform encryption and decryption.
Explanation:
- Cryptography is such a technique that is used for the secure transfer of the information. We make codes for this purpose.
- Cryptosystem is such a system in cryptography is simply an encryption method that has three algorithms. One algorithm is used for the generation of key, one for encryption and decryption.
- Encryption is a process of converting the information in a data that is not understandable and decryption, this non-understandable data is converted into information so that we can read it.
Answer: Preamble
Explanation:
Preamble is a 7- octet pattern of alternating the 0's and 1's and it allow devices in the network to easily synchronized the receiver clock. It also provide the bit level synchronization.
It basically allow the start of frame delimiter to provide the byte synchronization and assign a new frame. The bits are transmit orderly from left to right in the frame.
Answer:(1) To manage the computer's resources, which includes central processing unit, memory, disk drives, and printers, (2) To establish a user interface
(3)To execute and provide services for applications software.
The old mainframe computers have
(1) low memory sizes
(2) slower connectivity speed
(3) Larger sizer
(4) low sophistication.
Explanation: Operating system is a system software that manages the computer resources,helps to establish user interface and it helps to provide services for application softwares.
Operating system software includes WINDOWS X,WINDOWS 7,WINDOWS 8,LINUX,etc.
Mainframe computers are computers used by large multinational companies for processing bulk data. Old mainframe computers were produced by IBM(INTERNATIONAL BUSINESS MACHINE) in the year 1952 they are classed two scientific and commercial mainframe computers with different information although they had some incompatibilities. Old mainframe computers are large in size with low processing speed, sophistication and storage compared to present day system.
