Bandwidth

B.
Preboot Execution Environment (PXE)

C.

D.
Spam

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 option C 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 option 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 option D 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.
