Solutions
S1.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.
S2.Ans.(b)
Sol. Reboots can be either cold (alternatively known as hard) where the power to the system is physically turned off and back on again, causing an initial boot of the machine, or warm (alternatively known as soft) where the system restarts without the need to interrupt the power.
S3.Ans.(d)
Sol. Firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. It typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed not to be secure or trusted.
S4.Ans.(b)
Sol. A page break is a marker in an electronic document that tells the document interpreter that the content which follows is part of a new page.

S9.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.
S10.Ans.(b)
