What Is Computer Networks – Best Home Network Settings

What Is Computer Networks – Best Home Network Settings

What Is Computer NetworksWhen most people think of computer networks, they think of big companies. Many people network their home systems to enable shared Internet connections, shared files, and even shared print capabilities. The process of sharing resources and data between multiple computers is called a computer network. When you connect your computer, you can share your Internet connection, printers, faxes, and other components, as well as files, photos, songs, and other data stored on your hard disk.

Understanding Computer Networks – Networks are LAN networks where computers are shared within an office building or home space, local or small areas such as MAN, WAN where areas are shared in two or more locations. It can be divided into networks. Networks can be created to connect from anywhere in the country at home or in the office.

The most common use of WAN connectivity is to enable networks to connect to millions of computers around the world. WAN networks are the largest networks in the world and can be connected from anywhere in the world to anywhere in the world, provided the router and the appropriate software are running.

Computer networks can be wired or wireless, but not many people use wired features these days. Depending on the setup you need, how you access your main computer and how many people you need to connect to will determine the type of network you need to build.

There are two main ways to connect a computer: a client-server system and a peer-to-peer server. A client / server network consists of one or more main computers that act as servers in the network. Data, files, photos, documents, and other information are stored on these servers and accessed by various computers on the network. Other computers on the network, called clients, connect to the server to receive some or all of the information.

Peer-to-peer networks allow you to choose what information to share on each computer. No main server stores all of this. Each hard drive is open to the network, and all computers on the network are granted proper access to each system’s hard drive. Most home users use peer-to-peer network settings that allow them to select the information they need or need from each system in their home on the network. Most enterprises use client-server networks of different topologies, structures, or designs within their layouts.

A common language or communication between computers in a network is known as a protocol. The most common and commonly used protocol is TCP / IP, which works with multiple protocols, not just one. It can use the TCP / IP protocol, works with a wired or wireless connection, and is accessible via a client server or peer-to-peer network.

Home Network Settings

There are some great programs to help you set up your home network right away. You don’t have to be a network engineer, and you don’t need to know much about how a network actually works. Basically, it only has the system you want to connect or link to on the network, the internet connection, and the ability to follow simple instructions. If you have a wireless internet connection set up, you don’t have to worry about wiring cables from one computer to another. All that is done is to make a few simple changes to the network section of each computer.

You can create a password-protected and secure connection to prevent open connections to outsiders who want to spy on shared files. On each system, you have the option of choosing what to share and what not to share. You can create a folder for your network and put it on your virtual drive. That way, no one can access the hard drive of the actual computer, only the files and what’s stored there. The computer network process is simple and easy to run, making it much easier to run multiple computers at home.

Computer Network Basics (Fundamental of Computer Networking)

Fundamental of Computer Networking – Previously, when two individuals wanted to share data with each other, they relied on movable discs such as floppy disks and CD-ROMs. These methods of sending data between remote computers are often difficult, especially if the files are sent very often.

Due to the above difficulties in transmitting data over mobile disks, the idea of ​​networking two or more computers was born. Instead of sending files to a mobile disk, the computers are connected to each other with cables through the computer’s ports. If someone needs to send data to another computer, you can only share the files that need to be sent over the network. As you can see, there is no need to move disks and the problem is simple.

When we talk about computer networks, we need to distinguish between the many types that exist in the network. Computer networks can be categorized according to the geographic area they occupy or how they behave when sharing and accessing data between computers in the network.

First, let’s see how they are categorized according to their geographical area. The meaning of this classification is the amount occupied by the network or the size of the network. According to this classification, there are three types of networks. They are LAN, WAN, and MAN. LAN (Local Area Network) is the smallest size compared to other types. A LAN can occupy up to one room, one floor, a building such as a company, or a group of adjacent buildings. A MAN (Metropolitan Area Network) can occupy an entire city or a state of time. WANs, on the other hand, can capture countries as a whole, groups of countries, and even the whole world.

The second category is due to the distribution of data across the network and how interconnected computers handle it. According to this classification, there are two types of networks. One is a peer-to-peer network. The meaning of this classification is that all computers in the network are treated the same. Therefore, the size of the data on one computer can be the same as the size of another computer. Also, all devices have the same processing power and storage capacity. Therefore, no computer on the network is more valuable than any other computer. Therefore, the name is peer-to-peer network.

The second type of network according to the above classification is the client-server network. The difference with this type is that not all computers have the same value. At the very least, there are computers (called servers) with a lot of processing and storage power. Therefore, the data is stored on that computer and shared throughout the network. Any computer that needs data that is shared across the network can only get the data from the server. This is due to the small memory size and processor power of all computers except the server.

Computer Network Devices And Components

Computer Network Equipment and Components – Computer networks consist of a variety of devices for sharing, transmitting, and facilitating signals, voice, and data. A network device or component is a physical component connected to a network. There are a huge number of network devices and they are increasing every day. Basic network devices are personal computers, servers, hubs, switches, bridges, routers, modems, printers, DSL modems and routers, gateways, network interface cards, cable connections, and wireless access points. Below is an overview of each of these network devices.

Use of Computer Network

Personal computer: A personal computer is usually a desktop computer, workstation, or laptop. Personal computers are most widely used by any organization or for personal use. Personal computers are the most common type of microcomputer.

Server : A server is a computer on your network that processes requests and is used to share data and resources with other computers in your network. The server stores all the information you need and provides a variety of services such as workstation computer logon access, internet sharing, print sharing, and disk space sharing. There are many types of servers, including file and print servers, database servers, proxy servers, fax servers, and backup servers.

The database server stores all the data and software that may belong to a particular database, allowing other network devices to access and process database queries. A file server is used to store data for any user on the network, and a print server manages one or more printers in the network. Similarly, a network server is a server that manages network traffic.

Network Interface Card : A network interface card is used to connect to a computer or other network device and provide a connection between two computers. Each network card is specially designed for different types of networks such as Ethernet, FDDI, Token Ring, and wireless networks. Network cards work with the specifications of the first and second layers of the OSI model: the physical layer and the data link layer. The NIC basically defines the physical connection methods and control signals that provide the timing of data transfer over the network.

Hub: A hub is a simple network device. The hub’s function is broadcast. That is, data is sent to all ports on the hub, regardless of whether the data is targeted to a particular system in the network. Computers in the network are connected to the hub with twisted pair (CAT5) cables. There are two types of hubs. 1. Active hub. 2. Passive hub.

Switching Hubs: Switching hubs (also known as “switches”) are the most advanced form of basic hub. In a basic hub, all computers are connected to the hub, and the computer with the slowest network speed is connected to the network card. For example, if your network has a 10/100 Mbps card and only one card with a speed of 10 Mbps, the system cannot run faster than 10 Mbps. If your network has a switching hub, this allows for all high speed connections. Maintains high speeds on the network and interacts with 10Mbps systems.

Switch: A switch is an intelligence device rather than a hub. The switch is a layer 2 device. Swith offers the same functionality as a hub or bridge, but with the advanced features of temporarily connecting two computers. The switch consists of a switch matrix or switch fabric that allows you to connect and disconnect ports. Unlike hubs, switches send or forward data only to their assigned computer, not all ports.

Modem: A modem is a device used to convert digital data to analog format and vice versa. It performs two main functions. Modulation and demodulation. The modified data can pass through the traditional telephone line. The modem modifies the signal on the transmitting side and demolating it on the receiving side. Modems are required for a variety of access methods such as ISDN, DSL, and 56K data modems.

The modem can be an internal device that connects to the system’s expansion slot, or it can be an external device that connects to a serial or USB port. PCMCIA cards are used for this purpose in laptops, and many new laptops have an internal modem. Dedicated devices are designed for use in systems such as handheld computers. ISPs that require large modems use rack-mounted modems.

Router: A router routes data between two logically and physically separated networks. The router has the ability to determine the destination address of the data, providing the best way for the data to continue moving. Routers get this functionality through their own software called routing software. Unlike switches and bridges, which use hardware-configured MAC addresses to determine the destination of data, routers use logical network addresses, such as IP addresses, to determine the destination of data.

Gateway: The gateway performs the task of converting data from one format to another without changing the data. Gateways can be devices, systems and software. A computer with two NIC cards can act as a gateway. A router acts as a gateway, just as a router that routes data from an IPX network to an IP network is technically a gateway. The same is true for translational switches that convert from Ethernet networks to Token Ring networks.

Cables: There are two most common types of cables. 1.10BaseT and 10Base2. 10baseT is a pair of cables. There are two more types of 10baseT. 1. UTP (Unshielded Twisted Pair) and 2. STP (Shielded Twisted Pair. STP is the safest cable covered with silver coated twisted paper to protect the cable.

The other end is thin 10base2 copper. Like coaxial cables, cables often used to connect TV sets and VCRs. The 10base T / Cat5 cable is the most commonly used cable to connect computers. There is a connector called the RJ45 connector (such as a telephone connector). Yes, twisted pair cables are ideal for small, medium, or large networks.

Computer Network Setup And Repair

Computer network repairs weren’t heard a few years ago, just as computers weren’t thought to be needed 15 years ago. They were considered high-end luxury. However, things have changed and few homes without computers can be found. Without the help of a computer, a business cannot run at the optimal level. To use multiple different computers on the same premises, you need to connect them using a computer network. However, if there is a problem with your computer network, all computers can be affected.

Repairing computer networks is not something everyone is good at. Computer network problems at home or in the office require immediate attention from trained professionals. Huntsville computer repair specialists know what it takes to get your network up and running.
