Explanation:

A cookie is a small bit of text that accompanies requests and pages as they move between Web
servers and browsers. It contains information that is read by a Web application, whenever a user
visits a site. Cookies are stored in the memory or hard disk of client computers. A Web site stores
information, such as user preferences and settings in a cookie. This information helps in providing
customized services to users. There is absolutely no way a Web server can access any private
information about a user or his computer through cookies, unless a user provides the information. A
Web server cannot access cookies created by other Web servers.
Answer option B is incorrect. SSID stands for Service Set Identifier. It is used to identify a wireless
network. SSIDs are case sensitive text strings and have a maximum length of 32 characters. All

other. The SSID on computers and the devices in WLAN can be set manually or automatically.

assigned to the network interface card (NIC) by the NIC manuurer. This physical address assigned to
NIC is used for mapping in TCP/IP network communication.
