कंप्यूटर अवेयरनेस टेस्ट - 21

Ans.(c)

Sol. 01001010 is the 1’s complement for 10110101

 Ans.(d)

Sol. Simplex is unidirectional while half duplex and full duplex communication modes are bidirectional. Difference between half duplex and full duplex is that the transmission of data is done one at a time in half duplex while simultaneous data transmission takes place in full duplex communication.

Ans.(a)

Sol. 4 is the octal equivalent for binary number 100.

 Ans.(a)

Sol.  1’s complement of 1101 = 0010 = 2

 Ans.(a)

Sol. The term "garbage in, garbage out" originated in the computer science and information technology fields to illustrate the fact that the quality of the output received from a computer program depends on the quality of the information that was input.

Ans.(c)

Sol. The octal numeral system is the base-8 number system, and uses the digits 0 to 7.

Ans.(b)

Sol. Except for peripherals, all other options are examples of intangible instructions given to a computer to perform a specific type of task in on orderly manner.

Ans.(b)

Sol. Firmware is a collection of permanent instructions and codes stored in a read-only memory. The firmware is usually placed by the manufactures of computers to store vital information about how computer hardware devices will communicate with each other and how programs will run on hardware devices.  

Ans.(a)

Sol. John von Neumann is the first person who proposed the idea of stored program.

Ans.(d)

Sol. MICR or Magnetic Ink Card Reader is an input device that is used majorly in banks for processing cheques that contain MICR code.

Ans.(b)

Sol. Linux is an open source operating system.

Ans.(c)

Sol. Generally, we can use mouse for selecting or highlighting object.

Ans.(b)

Sol. The unit that stores all the data and information of a computer system is known as the memory or storage unit.

Ans.(a)

Sol. Main memory is closely related to processor. Therefore, the data, which is available in the main memory, is processed much faster than that in the secondary memory.

Ans.(c)

Sol. A processor speed is measured in Gigahertz (GHz). 

Ans.(c)

Sol. An MICR is a character-readable technology used for printing human-readable characters on documents by using a special magnetic link that consists of iron oxide. Standards to use the MICR have been set by the American Banking Association. It is basically used for processing cheques in the banks.

Ans.(d)

Sol. Buffer is used to hold data temporarily inside the computer memory. When different devices require the data, the buffer sends it on a priority basis, thereby differentiating the flow of data between the devices.

 Ans.(b)

Sol. BIOS in the computer system refers to Basic Input/ Output System. It refers to a computer program used at the time of startup.  

Ans.(b)

Sol. A bridge is a network device used at the data link layer to connect two dissimilar networks as well as similar networks.

Ans.(d)

Sol. As the installation cost of thinnet coaxial cable is less, it is also known as cheapernet. 

Ans.(b)

Sol. Except for peripherals, all other options are examples of intangible instructions given to a computer to perform a specific type of task in on orderly manner.
