Q1 Solution:
Computer network: the connection of computers and computing peripherals either using wires or radio waves over a small or large geographical areas. E.g. interconnection of many computers to a single printer. Depending upon the area covered computer network can as classified as PAN, LAN, MAN and WAN.
Personal Area Networks: an interconnection of devices in few meter distance which is connected wirelessly. E.g. connection of mobile phone over a wifi signal to a router.
Local area networks: computer network with an area of small geographical area such as campus premises, home, and office is termed as LAN. Printer, scanner are generally shared between computers in home and offices. Basically the sharing is done by wired media

Data may be any number, alphabets, images, videos and other representation such as attendance record of student, customer information in bank. Such data needs to be sent and receive between the different location and devices. So exchange of data is called data communication. In data communication message, sender, receiver, transmission media and protocol play a vital role. Messages are the actual data to be shared and it can be in any form. Senders are those devices which are used to send data and receiver are those devices which receives data. Transmission media may be wired or unwired and protocols are the set of rules to communicate.
Multiplexing: transmitting multiple information in a single medium has been made easier by the process called multiplexing. Using this technique the total bandwidth is divided and a portion is given to each signal. Multiplexer and demultiplexer are the devices used in multiplexing. The multiplexer combines the data from multiple source and sends via the single channel and demultiplexer separates the individual lines and transmits to corresponding output lines.
Multiplexing is of four types
Frequency Division Multiplexing
Code Division Multiplexing
Time Division Multiplexing
Wavelength Division Multiplexing
Network management: In a board sense network management is simply managing computer networks. It can be defined as configuring, testing, monitoring and troubleshooting network components, features and operations to achieve
1)A network is when two or more computers are connected together and are able to share data and communication.
An access point is a hardware device or configured node on a local area network (LAN) that allows wireless capable devices and wired networks to connect through a wireless standard, including Wi-Fi or Bluetooth.
A LAN is a ‘Local Area Network’. It is a small network of computers most often
It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.
Computer Network: A LAN (local area network) that connects computers in a house, at school or at work.
Data communication is the exchange of data between a sender and a receiver of the information. The components data communication has to have, to be a data communication are:
The _________ is a term for the device or unit that receives the information transfer.
data has to be, and what pieces of software computers need to have to send this kind of data.
Local Area Network or LAN for short is the term used for computer networks located at a single location such as a small business located at a singular location. They are generally used for businesses, organisations and the likes to transfer data amongst their systems as opposed to transferring data to outside of their location. A LAN typically will rely on wired connections due to the benefits of increased security and speed, but a network called a WLAN exists, which is a Wireless Local Area Network and this may prove useful for those who come to work using mobile devices such as laptops, phones, etc. WLANs are simply local area networks that consist solely of wireless connections using a wireless access point (WAP) as the central hub. However, LANs can be a mix of both wireless and wired.Typically in a LAN, systems connected to the network are able to share resources among each other, send data to servers and use peripherals such as printers, scanners &
A network enables all PCs and devices to exchange data with each other which means they can all communicate with each other with information and data.
LAN refers to Local Area Network. This is a network of computers in small areas. It is usually used in organizations, schools or even at home. A Local Area Network can be created with Ethernet cables and its components or via wireless technology. A Local Area Network has reduced security threats to its data in that for a person to access the data, they need to be within the small region with coverage which is mostly within the company’s or organization’s premises. As a result, this reduces the risk of unauthorized persons accessing the data.
Networks: wide-area network (WAN) a network that connects computers over a large geographic area, such as a state, province, or country. Local-area network (LAN) is a network that connects computers that are in close proximity to each other, such as an office building or a college campus.
A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.
A computer network is a network that consist of two or more computers that are able to share information between them or their users. There are a large variety of different networks and the advantages or disadvantages are strongly related to the type of network we choose.
Computer networking is sometimes considered a sub-discipline of electrical engineering, telecommunications, computer science, information technology or computer engineering, since it relies upon the theoretical and practical application of these disciplines.
