[#561] Which of the following chips can be reprogrammed with special electric pulses?
Correct Answer

(D) EEPROM

Explanation

Solution: EEPROM : EEPROM (also E2PROM) stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless system, and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed.

[#562] In this world of fast changing computer technology, one of the most important factor to be considered while purchasing a PC is, it should have a provision for
Correct Answer

(B) self upgradability

Explanation

Solution: In this world of fast changing computer technology, one of the most important factor to be considered while purchasing a PC is, it should have a provision for self upgradability. It saves time, efforts and money compared with letters used, before making influence of computers in human life.

[#563] A collection of eight bits is called
Correct Answer

(A) Byte

Explanation

Solution: Byte : The byte is a unit of digital information that most commonly consists of eight bits, representing a binary number. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.

[#564] The ALU of a central processing unit does the essential maths work for the computer. What does the control unit do?
Correct Answer

(C) Monitors the flow of information

Explanation

Solution: The ALU of a central processing unit does the essential maths work for the computer in monitors the flow of information. The control unit tells the ALU what operation to perform on that data, and the ALU stores the result in an output register. The control unit moves the data between these registers, the ALU, and memory.

[#565] Which of the following storage and retrieval methods would be well suited to your processing requirements if you only need to retrieve records one at a time and there is no fixed pattern to the requests for data and records?
Correct Answer

(D) indexed direct

Explanation

Solution: The storage and retrieval methods would be well suited to your processing requirements if you only need to retrieve records one at a time and there is no fixed pattern to the requests for data and records an indexed direct. The systematic process of collecting and cataloging data so that they can be located and displayed on request.
