What is the difference between system software and application software?
Both system software and application software are programs for the computers, but system software includes the programs that are provided together with the installation of the operating system for the computer. Basically, system software is the files and programs that comprise the operating system. This kind of software is also known as the software of low level, as it operated on the most basic level of the work of a computer. The function of system software is to create convenient graphical interface for the users, so that they could communicate with the hardware of the computer. System software provides the connection between the user and the computer hardware.

At the same time, application software includes the additional programs that are designed to utilize the computer’s abilities; it allows the user to accomplish specific tasks (Jamal, par. 1). Word processors such as Microsoft Word and media players such as Windows Media Player are the examples of application software. This kind of software cannot operate without system software, while system software can run on the background and does not need to be assisted by the application software (Andrew, par. 7). The examples of system software are Microsoft Windows, Linux and DOS.
What is the difference between a Local Area Network (LAN) and a Wide Area Network (WAN)?
The main difference between LAN and WAN is the size of the areas they cover. LAN is the name commonly used for the computer networks that are designed to connect various computers in smaller areas such as schools, offices or homes. LAN is convenient because it enables its users to share files, games or printers. LAN consists of several computer systems, one of which is connected to the Internet by means of a router or a modem (Difference between LAN and WAN, par. 3).
WAN is not restricted according to its geographical location, but it can be limited by the borders of a country or a state. An example of a public WAN is the Internet, which can connect people from all parts of the world covered by the net. WAN is used to connect several LANs, the connection may be constricted to a certain company, or it may be open for the public access (Archived: What is the difference between a LAN, a MAN, and a WAN?, par. 4). The connection I currently use is provided by a local area network or LAN.
What is the difference between a static and dynamic Internet Protocol (IP) address?
Static Internet protocol addressing means that a computer and its user have one IP address. This kind of IP address is constant and does not change. A certain IP address may be registered for just one computer. At the same time, dynamic IP addressing means that many users are sharing the same IP address, which could change every time a user that is also a customer of a certain Internet service provider logs on to their computer. However, the change of a dynamic IP address may happen more seldom, in case if the Internet provider decides to change the IP address only when they think it is needed (Dynamic IP vs. Static IP, par. 1). Static IP creates security risks. Its stability makes the address easier to track. Static IP addresses are convenient for the computers that are used as servers because they speed up the file downloads and uploads. Besides, static IP is good for web site owners.
