Q1. Input, output and processing devices grouped together present a(n)___________.
(a) Memory
(b) Information
(c) Data
(d) Computer system
(e) internet
Ans.(d)
Sol. Input, output and processing devices are basic units of a Computer System.
Q2. Which of the following device used ‘set of beads’ to represent the unit of data?
(a) Monitor
(b) EDVAC
(c) Abacus
(d) MARK-I
(e) ENAIC
Ans.(c)
Sol. Abacus used ‘set of beads’ to represent the unit of data
Q3. Which of the function in Computers is the one that control processes and accept data in continuous fashion?
(a) Data traffic pattern
(b) Data highway
(c) Highway loop
(d) Feedback loop
(e) All of these
Ans.(d)
Sol. Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.
Q4. EEPROM stands for ________.
(a) Electrically erasable programmable read-only memory
(b) Elementary erasable programmable read-only memory
(c) Electronics and electrical programmable read-only memory
(d) Electrically erasable Principal read-only memory
(e) None of these
Ans.(a)
Sol. EEPROM stands for Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed.
Q5. Which of the following options is the name of the main folder on a storage device?
(a) Platform
(b) Interface
(c) Root directory
(d) Device driver
(e) Internet Explorer
Ans.(c)
Sol. The root directory is the first or top-most directory in a hierarchy. It can be likened to the trunk of a tree, as the starting point where all branches originate from. The root file system is the file system contained on the same disk partition on which the root directory is located; it is the file system on top of which all other file systems are mounted as the system boots up.
Q6. Which among the following is a special visual and audio effect applied in PowerPoint to text or content?
(a) Animation
(b) Flash
(c) Wipe
(d) Dissolve
(e) None of these
Ans.(a)
Sol. Animation is a special visual and audio effect applied in PowerPoint
Q7. The Internet is a system of ___________.
(a) Software bundles
(b) Web page
(c) Website
(d) Interconnected networks
(e) None of these
Ans.(d)
Sol. Internet is a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.
Q8. Which among the following is an example of loopback address?
(a) 127.0.0.1
(b) 225.0.0.0
(c) 255.255.0.0
(d) 126.0.0.1
(e) None of these
Ans.(a)
Sol. The range of addresses for loopback functionality is the range of 127.0.0.0 to 127.255.255.255. Loopback is a communication channel with only one endpoint. TCP/IP networks specify a loopback that allows client software to communicate with server software on the same computer. users can specify an IP address, usually 127.0.0.1, which will point back to the computer's TCP/IP network configuration.
Q9. Which among the following is a term for one or more defects or problems that prevent the software from working as intended or working at all?
(a) Bug
(b) Bot
(c) Programming language
(d) Fuzzy logic
(e) None of these
Ans.(a)
Sol. A software bug is an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.
Q10. Concept of cache memories was introduced in _______ generation of computer.
(a) Second
(b) Third
(c) Fourth
(d) Fifth
(e) None of these
Ans.(b)
Sol. In Third Generation of computers the concept of Cache Memory was used.
