Solutions :

S1. Ans.(a)
Sol. A heat sink is a component of a motherboard which absorbs the heat produced by the processor and other components of a computer. 

S2. Ans.(d)
Sol. Operating system provides an interface between a user and computer hardware. It enables a user to utilize hardware resources efficiently. 

S3. Ans.(c)
Sol. A light pen is a pointing device that uses a photoelectric (light-sensitive) cell to indicate a position on the display screen. 

S4. Ans.(b)
Sol. A Graphical User Interface (GUI) is a usual interface that allows users to interact with the computer through graphical elements such as pictures and animations.  

S5. Ans.(c)
Sol. Generally, we can use mouse for selecting or highlighting object. 

S6. Ans.(b)
Sol. The unit that stores all the data and information of a computer system is known as the memory or storage unit. 

S7. 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. 

S8. Ans.(c)
Sol. A processor speed is measured in Gigahertz (GHz).  

S9. 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.

S10. 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. 

S11. 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.   

S12. 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. 

S13. Ans.(d)
Sol. As the installation cost of thinnet coaxial cable is less, it is also known as cheapernet. 

S14. Ans.(a)
Sol. In 10BaseT, 10 means the transfer rate of this Ethernet is 10 Mbps; Base describes the type of signaling used, that is, Baseband; and T denotes that the cable used is twisted-pair cable. 

S15. Ans.(d)
Sol. A wireless network allows a user to connect different computers or devices by using wireless network protocols. It provides mobility by allowing access to a network irrespective of the location. The installation of a wireless network is easy compared to a wired network. Also, a wireless network does not require expensive wires or cables; therefore, this type of network is cost effective. However, this type of network is insecure as data travels in the air.
