An Overview of Wireless Local Area Network Technology

Wireless Local Area NetworkA WLAN provides wireless connectivity over short to long distances with radio waves rather than traditional electrical network cabling. A WLAN extends already existing wired local area networks (LAN) to computers not attached to the LAN directly. The term ‘wireless’ denotes that the system does not require any wires connecting the computers or devices to the network. It uses radio signals for this purpose.

There are four main types of wireless local area networks: single-mode, multimode, bridged, and a packet switch. Each has its pros and cons and can be used for various applications. In single-mode networks, the primary (and least important) mode of connectivity is fixed and the secondary mode covers either one or two modes. Bridged and packet switch networks combine the features of both single and dual-mode networks. The fourth network type offers faster connectivity and provides more efficient power consumption.

Advantages and Disadvantages of Local Arean Network

A local area network (LAN) refers to the network which connects computers inside a very limited geographical area, such as colleges, schools, or universities. A LAN is a logical connection between devices that are located at different places. They offer a useful method for sharing resources among end-users. The term LAN was first used in 1982 by Bill Atkinson, who distinguished it as a logical interconnection system, in which multiple links could be established between computers through their location. This network has been very useful for computers because the number of computers on the network does not matter much unlike the Internet, where there are hundreds of millions of IP addresses to be dealt with.

Today, a Local Area Network has emerged as one of the most popular technologies used to connect computers and allowing them to share files and information. There are many advantages to using a Local Area …

Establishing A Personal Area Network

A personal area network (PAN) is a computer network dedicated to interconnecting personal devices with each other and often with devices in the network. Such computer networks utilize technologies such as ATM, IP, iSCSI, and Fibre Channel (FCoE). Such computer networks are highly useful in the telecommunication industry for application and disaster recovery purposes.

The term Personal Area Network refers to a central information repository for personal computers. Such a system is made up of different devices that work as part of a larger system, thereby sharing input/output, processing, and communication functions. Such a system is often customized for specific purposes like workgroup or work division. It can be used for connecting devices running different operating systems. Personal area networks can connect devices running Microsoft Windows, Linux, Apple OS, Novell Netware, OpenBSD, and other operating systems. Some devices can connect to Personal Area Networks even if they do not run …

Computer Hardware Engineer Job Description

If you are looking for a job that combines your technical knowledge with creativity and problem-solving skills, you may want to consider working as a computer hardware engineer. As an engineer, you will be involved in the creation of computer hardware systems for both the private and public sectors. You will be responsible for designing and building computers and other computer hardware. You will work directly with software and hardware vendors and will be responsible for producing the best possible system with the least amount of defects. How do you learn how to become a computer hardware engineer?

Education. Most entry-level computer hardware engineers have at least a bachelor’s degree in computer hardware engineering, though a bachelor’s in electrical or computer engineering is also usually acceptable. A computer engineering major typically is like a major in mechanical engineering but with a strong emphasis on computer hardware engineering. Many schools offer …

Common Types of Computer Viruses

There are four a variety of computer viruses classified judging by the various in the computer they cause harm to. The following is a list.

(a) Boot Sector Computer Virus

These viruses include the most popular. They harm the boot records present on just about any digital storage equipment, like the hard drives with the computer and all peripheral disks which are suited for them, including DVDs, CDs plus much more commonly on floppy disks. These viruses might be loaded at any time using the pc, however, they become active after the boot record has been used from the computer, i.e. if it boots when. Once they become active, they become very difficult to remove. The redundancy of floppy disks in today’s times has triggered a reduction in a good boot sector viruses.

(b) Master Boot Record Computer Viruses

These viruses are specialized versions from the boot sector viruses, in …
