Components of Computer Network
Network Devices:
- Routers: Routers switch data packets between two or more networks and regulate traffic to increase the efficacy of the data transfer. These are important in teleporting local area networks to the internet and canaring that data to the intended destination.
- Switches: Switches as a part of a network join devices together, and forward information only to the target device. They help to reduce network clutter hence improving the efficiency of the network.
- Hubs: Switches are fundamental networking devices that transmit data to every connected device. They are less efficient than switches because they cannot distinguish the endpoints for delivering data packets, which can significantly cause traffic jams in the network.
- Access Points: There are connection points that facilitate connection of a Wireless network which connects any device to a network by use of Wi-Fi. Developers require them to create and expand wireless networks.
Links:
- Wired Links: It is a connection that is based on the use of cables such as Ethernet cables or fiber cables to provide a secure and high-speed link. People typically choose them for their stability and the speed at which they execute instructions.
- Wireless Links: Wired connections employ cables for their data transfer whilst wireless connections employ radio waves for connection; some of the wireless connections include Wireless fidelity commonly referred to as Wi-Fi as well as Bluetooth.
Communication Protocols:
- TCP/IP: The Internet primarily relies on TCP/IP as its principal protocol for communication. It is responsible for the communication and the delivery of data packets all over the network.
- HTTP/HTTPS: The World Wide Web relies on two protocols for accessing, transferring and viewing hosted documents and info namely Hypertext Transfer Protocol (HTTP) and the secure version of HTTP (HTTPS). HTTPS has utilizable encrypting capabilities used for safe conveyance.
- FTP: FTP is an application that allows the inter-transfer of files from one device to another in a network. People extensively adopt it for transferring documents between clients and servers.
Network Defense:
- Firewalls: A firewall is essentially the mechanism that scrutinizes the incoming as well the outgoing traffic following certain security parameters decided by the specific company.
- Intrusion Detection Systems (IDS): IDSs patrol the network, surveilling for any malicious activities, and trigger an alarm if they detect any.
- Virtual Private Networks (VPNs): VPNs protect information transmitted over the Internet by encrypting the data, ensuring secure communication.
Types of Network Threats
- Viruses and Malware: Malware, such as viruses, worms, and ransomware, pose harm in terms of corrupting files, embezzling information, or halting network performances. These threats warrant routine updates and security measures, as attackers can exploit vulnerabilities.
- Phishing: Phishing scams aim at tricking the users into divulging sensitive information under the guise of a genuine institution such as a bank or service provider. Attackers typically carry out such attacks through phishing, sending fake emails or messages to unsuspecting users.
- Denial of Service (DoS) Attacks: DoS attacks flood a network with traffic that it cannot handle and therefore make the network unavailable to anyone who wants to use it. Distributed Denial of Service (DDOS) attacks are carried out by one target being attacked by multiple systems.
- Man-in-the-Middle (MitM) Attacks: Man-in-the-middle (MitM) attacks intend to compromise and may even modify data interchange between two parties without their consent. This type of attack can endanger data and interface with other gadgets in the system.
- Data Breaches: It means that the unauthorized person may intercept as well as steal or misuse some sensitive data. Hacking, internal threats and poor security measures are ways through which data may be breached.
- Ransomware: Ransomware locks a victim’s data and then demands a ransom for its decryption. Abnormalities can bring about major disturbances to commercial activities and data information access.
- Password Attacks: Password attacks include: guessing, cracking and stealing of passwords. You can address this danger by using strong, specific passwords and multi-factor authentication procedures.
Computer Networks: Business Application
- Data Management: Networks facilitate data storing and retrieval systems as well as data security because they help facilitate the organization’s data storage system. This has the added advantage of ease of backup and recovery as well as sharing of information across the system.
- Collaboration Tools: Most common applications include shared documents, project management systems as well as communication systems all of which increase instance connectivity between teams. All these tools enhance real-time cooperation and sharing of information.
