220-601 CompTIA A+ is part of the certification track for corporations such as Microsoft, Hewlett-Packard, Cisco and Novell. Other technology companies, including CompuCom and Ricoh, have made CompTIA A+ certification mandatory for their service technicians. More than 700,000 people worldwide have become CompTIA A+ certified since the program’s inception in 1993.

The international, vendor-neutral certification proves competence in areas such as installation, preventative maintenance, networking, security and troubleshooting. CompTIA A+ certified technicians also have excellent customer service and communication skills to work with clients.

The latest version of CompTIA A+ is CompTIA A+ 2009 Edition. Two exams are necessary to be certified: CompTIA A+ Essentials, exam code 220-701; and CompTIA A+ Practical Application, exam code 220-702.

220-601 CompTIA A+ Essentials measures the necessary competencies of an entry-level IT professional with a recommended 500 hours of hands-on experience in the lab or field. It tests for the fundamentals of computer technology, networking and security, as well as the communication skills and professionalism now required of all entry-level IT professionals.

TestInside 220-601 Practice Test Questions will help you prepare for your 220-601 exam. The 220-601 practice exam covers the exam objectives and topics you will be tested on. TestInside replicates the actual online exam environment by providing a computer-based, timed testing environment. TestInside 220-601 practice exam testing engine will feel like you are taking the actual exam. The 220-601 testing engine simulates the actual exam experience.

CompTIA A+ Practical Application is an extension of the knowledge and skills identified in CompTIA A+ Essentials, with more of a “hands-on” orientation focused on scenarios in which troubleshooting and tools must be applied to resolve problems.

A computer network is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. This interconnected system will share services and interact through a communications link. If data is being sent over the system then the individual computers must follow a set of common communication rules in order for the data to arrive at is correct destination. This is also vital for the systems to properly understand each other otherwise data will not be received. These rules are known as protocols.

So, in order for a computer network to be set up properly four things must be present: two or more systems, something to share (such as data), a communications link or physical pathway, and a set of rules for communication or protocols.

Wireless computer networking uses radio waves and/or microwaves to maintain open communication channels between computers. This version of computer networking is a more modern approach and is an alternative to wired networking. The advantages of wireless computer networking are that this involves mobility and the elimination of a copper or fiber optic cabling running between computers. However, a wireless computer network has the potential to have radio interference due to weather, other wireless devices or obstructions.

If you are unsure what type of computer network you would like you can have a trained professional come to your home, business, or other location and have them recommend what you need depending on what you are using your network for. You should always hire a trained computer specialist when setting up a computer network as there may be complications and it can be very difficult to learn how to set up a computer network by yourself.

A group of interconnected devices sharing information and resources together is known as network. Or, sharing information and resources between devices is called computer networking.

Advantages of Computer Networking:

Connectivity and Communication: Networks can connect different computers and the users of those computers. This makes the transmission of business or non-business information easier, more efficient and less expensive than it would be without the network.

Data Sharing: One of the most major uses of computer networking is to share the data among multiple users. It enables thousands of users to share data much more easily and quickly.

Hardware Resource: In computer networking, you can also share hardware resources like printer, CD drive etc. Its true that one printer can be placed on the network to serve multiple employees.

Internet Access: The Internet is itself a kind of network, so when you surf the Internet, you are using a computer network.

Computer networking can be of various types as mentioned below:

Local Area Networks (LAN): Local area networks, generally called LANs, are privately-owned networks within a single building or campus of up to a few kilometers in size. They are widely used to connect personal computers and workstations in company offices and factories to share resources and information. LANs are restricted in size as distance varies from 1 to 10 km. Traditional LANs run at speeds of 10 Mbps to 100 Mbps. Newer LANs operate at up to 10 Gbps.

Wide Area Networks: It is a collection of more than two LANs. A WAN is any network that crosses metropolitan, regional, or national boundaries. A WAN as any networks that uses routers and public network links.

Metropolitan Area Networks: A MAN covers a city. The best known example of a MAN is the cable TV network available in many cities. A MAN is smaller than a WAN but bigger than a LAN.

SAN: Storage area network a SAN is a dedicated high-performance network used to move data between servers and storage resources.
