IT for Business 1
Q1.
It has been decided to buy parts and build a personal computer. The minimum components that
will be required for this device are processor, motherboard, storage, memory, and graphics
processing unit, case and power supply (Wolf, 2012).
Q2.
The most important features that need to consider before purchasing PC are (PCW, 2018): -
 Size
 Screen Quality
 RAM
 CPU
 Keyboard quality
 Battery life
 Build Quality
 Finger reader and TPM
 USB 3.0
Q3.
WAN: - WAN stands for wide area network, it is a far-reaching system on networks (Kuyoro,
Osisanwo & Akinsowon, 2015). WAN include multiple MAN's and LAN's that get
connected to the distance of more than 48 kilometers which is approximately equal to 30 miles.

MAN: - MAN stands for Metropolitan Area network, this network gets linked with the numerous
LAN available within a large city or metropolitan region. This network can be used by the
individual or group within the distance of up to 50 kilometers that is 30 miles approx.
LAN: - LAN stands for the local area network, it is one of the computer networks that is used
within a single campus or building (Kuyoro, Osisanwo & Akinsowon, 2015). Therefore, this
system of the network is mainly used by the offices within the radios of 5-6 kilometers which are
equal to 3-4 miles.
PAN: - PAN is a wireless network that is designed with the objective of handheld and portable
devices like cell phones, tablets, laptops and many others. Therefore, this network is used by
only one or two people. The transmission speed of the network is low and the highest difference
between the devices is 10 meters.
Q4.
Optical fibers have mainly replaced copper wire communications in the core networks in the
advanced world because of its advantages over the electrical transmission. Some of major
advantages are: -
 Extremely high bandwidth
 Longer distance
 Low security risk
 Resistance to electromagnetic Interference
 Small Size
 Easy to Accommodate Increasing bandwidth
 Light weight

Q5.
This is the fact that Wi-Fi is around us and it is used by pervasiveness. The use of the Wi-fi
universally also have some of the downsides. Some of them are: -
 High cost of pervasive service
