Introduces concepts of personal computer networking
Historically, personal computers have operated in a stand-alone state, with their own CPU, but organizations have increasingly come to rely on a shared environment for data and other resources. Local area networks (LANs) are networks of autonomous computers that span a building or a campus, and provide superior performance and security. LANs are generally small and operate on the concept of load sharing, in which data and programs are downloaded into a personal computer's memory to be executed.
A local area network (LAN) connects two or more computers together, typically using one Internet connection. Users can share files, print to shared printers, and access each other's personal computers from anywhere. LANs were first developed in the 1960s for use in large research facilities, colleges, and universities. In the early 1980s, dozens of computers were commonplace in offices and home offices. The ability to share expensive disk space and printers was appealing to many administrators and users.
In the mid-1980s, Unix workstations began using Ethernet technology for local networks. In the 1990s, the network became an industry standard when it was adopted by the IEEE. Since then, technology has improved dramatically, and modern Gigabit Ethernet standards are 100x faster than the old 10Mb/s cards. In some areas, however, these networks are still used. In these cases, it is important to note that the Ethernet standard is a standard, not a proprietary protocol.
A local area network, or LAN, is a network of computers and other devices within a circumscribed area. The network typically uses a TCP/IP ethernet or wireless networking media to connect the computers. In some cases, a LAN is exclusive to an organization. The idea behind LANs began in an area called the ether, which is similar to the 19th century concept of aether, the medium between the sun and Earth.
LANs and WANs are both types of networks that allow computers to communicate with one another. LANs and WANs use local area networks (LANs), while the latter is a more extensive network. Both are difficult to design, however. WANs tend to be slower than LANs and have more congestion and fault tolerance than LANs. WANs typically use a satellite link or a PSTN connection to transmit data. This type of network is not ideal for personal computer networking because it increases error and noise due to long-distance transmission.
Wide Area Networks are used in business and government settings to connect various sites. These sites may be miles apart or halfway around the world. WANs enable remote workers to access centralized resources. WANs are frequently compared to LANs, which are generally internal to one building or small campus. Home Wi-Fi networks are also examples of LANs. Although LANs are generally slower and cheaper, the speed of wide-area networks has become higher over time.
WANs have evolved over the last few decades. First developed by the U.S. Air Force, WANs were used to connect radar defense sites. At that time, LANs used dedicated phone lines or telephones. Later, the Advanced Research Projects Agency Network (ARPANET) became the foundation for IP-based Internet. It connected the University of California, Los Angeles, the Stanford Research Institute (now SRI International) and other institutions.
Explains security concepts
Understanding security is important for any network, whether it's personal or corporate. Network security includes measures to ensure data integrity, confidentiality, and accessibility. Increasingly, personal and company data is stored online and on different devices. If unauthorized users gain access to this information, the results can be disastrous. The good news is that there are many ways to protect data and network infrastructure. In this article, we'll cover some of the most basic security concepts.
The goal of network security is to prevent unauthorized users from accessing the network and any data contained within it. This can be accomplished through the use of firewalls, anti-virus programs, and virtual private networks, to name a few. It all begins with a secure password and username. Other security techniques may involve antivirus software, virtual private networks, and firewalls. By combining these measures, security is the foundation for personal computer networks.
In the world of personal computer networking, security can be categorized into three main categories. The first category, protection, focuses on the tools and policies that protect data. The second category, detection, refers to resources that analyze network traffic and detect problems before they cause harm. The last category, response, focuses on the means of responding to identified threats. The best protection, however, is a combination of all three.
CPU usage is a common symptom of network errors. Your network devices work much harder to complete tasks when CPU usage is high. If CPU usage is high, it may be time to upgrade your networking software. Then you can ask users to describe any difficulties or errors they have encountered. Depending on the cause, this may be a problem with the entire network, or just with a few users. However, if the errors are user-specific, you may be able to pinpoint the cause.
