Discussion 3
Basic computer requirement
The minimum things that would be required are a monitor, a keyboard, a mouse, a
central processing unit or the CPU consisting of a processor, a motherboard, a random access
memory or the ram, a graphics processing unit or the GPU, a hard disk or the HDD and a
switched-mode power supply or the SMPS and a set of speakers (Tanenbaum 2016).
Things to consider before purchasing a PC
The most important feature that is to be considered before purchasing a personal
computer is the processor, the mother board and the ram. These three things define the
working process of the computer. In order to get better speed one needs to get the most recent
released processors like the inter i7, 8 generation (Abbott 2017). Apart from this the monitor,
keyboard and the mouse are also required for the input and the output of the system.
Networks
WAN- Wide area network or the WAN is the interconnection between the computers
over a network in a broad geographical area, a good example of this is the Internet.
LAN- The local area network or the LAN is the interconnection between systems in a
small area over the network (Paul et al., 2016). It can be wired connection or wireless,
example is the computers connected inside an office.
MAN- The metropolitan area network is the connection between the system is a
network spread in a large zone, smaller than the WAN connection but larger than the LAN,
example a smart city.
