5.1 HARDWARE
What is computer hardware? According to Tim Fisher (2017) stated that computer hardware can be referred to the physical components that make up a computer system. A hardware can be installed and have many different types on a computer and it also can be connected from outside of the computer. A part such as a motherboard, central processing unit (CPU), random access memory and etc, can be found inside the computer housing. While monitor, keyboard, mouse, speaker and etc that outside of the computer also considered as a hardware that can be integrated with a computer. All these are the devices work together to accept, process, show data, and information for the users.
However, computer hardware sometimes its components individually

5.2 SOFTWARE
According to Jolli Ballew (2017) stated that software, in broad terms, is a set of instructions (generally referred to as code), that is positioned between you and the device’s hardware, enabling you to use it. But what is computer software, really? In layman’s terms, it’s an invisible component of a computer system that makes it possible for you to interact with the computer 's physical components. Moreover, software is what allows us to communicate or use with smartphones, tablets, media players, and similar other devices. Software also allows the hardware to process the data for the user.
However, it is important to know and understand that there is a distinct difference between hardware and software. Software is an intangible resource and it cannot be held in our hands meanwhile hardware consists of tangible resources such as a mouse, keyboards, USB ports, CPUs, memory, printers, and etc. Hardware and software need to work together in order to make a system fully

Besides, a network is a most important types of data communications in the organization. Network plays an important part in connecting with one computer to another computers and acts as peripheral devices to share resources and data. An example number of network configurations is local area network (LAN). LAN is a computer and peripheral devices that are located relatively close to each other and usually can be used in the same building or place. Next is client/server networks. It is a network that has file server to one or more computers that act as the central storage locations for programs and to provide a mass storage for most of the data that used on the network. Other than that is peer-to-peer networks. It is a network that when a network does not have any file server, computer and program are same and data will be spread among
1.3 How do local area networks (LANs) differ from wide area networks (WANs) and backbone networks (BNs) Local area networks are limited within an organization Wide area networks extend over a large geographical distance and may be privately owned or rented Backbone network are the part of network infrastructure that feeds the connected networks 1.8 Describe the seven layers in the OSI network model and what they do. Application – this layer is specific to applications and provides services such as email, network software services and file transfers Presentation - In this layer, the data is formatted in a schema that network understands, and also manages data encryption and decryption Session – this layer establishes and controls the data communication between
Several components required to implement VPN depends on the type of VPN i-e. Remote Access VPN, or site-to-site VPN. Network design is crucial to decide the throughput, choice of devices and number of users. There are two types of networks where VPN is needed to implement. 1. Site-to-site VPN—is provides connection between branches i-e. LAN-to-LAN VPN with their own internet instead of dedicated leased lines.
One of biggest roadblock that companies have to face is to invest a lot of money on implementing a software system and have employees ignore it and keep trying to do the task in their own way. This the reason why the provider that you choose for implementing your software have to be a natural fit for the organization. If the owners and employees have the same passion and understanding of the product that they would implement the result would be a success (Phillips, 2016).
It offers a secure fitting together between internet browsers and websites, letting you to communicate secretive data online. Physical Layout • Topologies; topology can be measured as a computer-generated nature or construction of a system. This shape does not agree to the real physical plan of the policies on the computer network. • Ring; basically in a ring system each device (workplace, waiter, and copier) is related to two other devices, this systems a ring for the signs to travel around. Each packet of data on the network trips in one way and each device collects each box in turn until the journey 's end device receives it.
Both types of networks provide network services using operating systems that can communicate with each other through common protocols. Each of these networks enables control of how users and programs get access to resources. Also, clients in a client server network and nodes or hosts in a peer-to-peer network use any combination of desktop, mobile, or tablet operating systems. 2. Discuss the difference between a physical topology and a logical topology.
IP addresses allow network resources to be reached through a network interface. If one computer wants to communicate with another computer,
A Keyboard allows for you to enter different characters such as letters, numbers and symbols. Each key on a keyboard represents a different character on the computer. There are several different types of keyboards, Ergonomic Keyboards, QWERTY Keyboards, and Braille Keyboards. Another example of an Input Device is a Mouse. A Mouse is a Pointing Device which allows you to move the cursor on the computer.
For this particular task, I will be explaining what key components are necessary for client workstations to connect to a network and how to access network resources. I will be explaining the key features and functions of each of these components in relative detail. Network Devices: These are mechanisms used to connect computers and other electronic devices together so they can exchange and share files or special resources like printers or fax machines used in big organisations. LAN is the main type of network device used by the community.
Components Computers have one or a lot of big or small R-A-M chips inside. RAM chips are a random access memory chip inside, the computer uses it to store information that will be used anytime or used to store something like the copy clipboard(The copy clipboard is the thing that stores what you copy to paste later) to delete/change later. There is also a spinning or solid state hard drive that uses DVD like disks that stores information like your video games, pictures, or other things. A CPU is the thing that your computer uses to do all the processing work, like our brain but not like it. CPU stands central-processing-unit.
This component is when you transmit any file from one computer to another computer, this is usually a much larger file. Most of the webs users would explain this simply as sending it to another computer that is set up to receive it or to send it up onto the internet where several people will be able to access it from their own computers. For example, YouTubers upload their videos on to the YouTube
Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
P2 Explain the purpose of operating systems Without an operating system the computer cannot function. An operating system is described as the system software that represents the essential layer between the BIOS and the applications software such as word processor, presentation, database etc. Operating system manages use of the system’s hardware and software such as time sharing and multi-tasking. It provides a consistent way for applications to interact with the hardware and for users to interact with the software and hardware. Operating system is important because it allows the computer to serve a variety of tasks instead of just one.
Fundamentals of Networking IT204-1701A-03 Unit 1 Discussion Board 2 Andrew LeLusche Professor Gregory Roby Colorado Technical University 1/6/2017 Fundamentals of Networking IT204-1701A-03 Unit 1 Discussion Board 2 In order to choose the correct network for your needs, it is important to first understand the differences, advantages, and disadvantages between a peer to peer network and a client/server network. Whether you are a family home, a mom and pop shop, a data center or large corporation- there is a network for your needs. A network is a system of operating machines that allows a user to access an interface suitable for creating and saving documents, access webpages and video/audio content, run administrative programs to serve clients based on whatever business model or service provider you are. First let’s discuss a peer to peer network.
It is defined by RFC 1350. It uses a client-server architecture. After establishing an FTP connection, the user can download or upload files to and from the FTP server. It is a simple version of FTP, lacking some more advanced features FTP offers. It can be used only to send and receive files.
The first computer is for the teacher’s purpose only, but the second computer is used for the children doing sensory play. Sensory play is when the children free play with different activities. For example, some children 's choice to sit around the table
