Correct Answer: C
Explanation:
Bandwidth is a term that refers to the data rate supported by a network connection or interface.
Bandwidth (or digital bandwidth) is a measurement of how much data can be sent in a period of
time. It is a data rate measured in bits. The standard unit of digital bandwidth is bits per second
(bps). In radio communication,
bandwidth (analogue bandwidth) is the range of frequencies occupied by the radio signals. The
standard unit of analogue bandwidth is Hertz (Hz).
Answer D is incorrect. In Web site designing, branding refers to the look and feel of a Web site.
Branding helps in differentiating a site from its competitors and also helps the customer to develop
a relationship with the Web site. The look and feel of a Web site comes through logo, fonts, color
schemes, and symbols used in the Web site. The overall look of the Web site should be consistent.
Answer B is incorrect. Preboot Execution Environment (PXE) is an environment to boot computers
using a network interface independently of available data storage devices like hard disks or installed
operating systems. PXE is also known as Pre-Execution Environment.
Answer A is incorrect. Spam is a term that refers to the unsolicited e-mails sent to a large number of
e-mail users. The number of such e-mails is increasing day by day, as most companies now prefer to
use e-mails for promoting their products. Because of these unsolicited e- mails, legitimate e-mails
take a much longer time to deliver to their destination. The attachments sent through spam may
also contain viruses. However, spam can be stopped by implementing spam filters on servers and
e-mail clients.
