Remote PC access is a recent technological development in computer networking. It allows users to open or transfer files and even operate applications in a host computer using another computer or device.
In the early days, remote access was only made possible with small network connections called virtual private networks (VPNs), which allow users to connect a home computer to the local area network (LAN) in their work office.
Currently, however, the internet has revolutionized remote PC access. Many remote access software programs are currently available at present, usually providing free remote clients and servers to end users. These remote servers, hosted via the internet, serve to create remote connections between host computers and network access devices.
There are several kinds of remote access programs commercially available today:
• Attended programs cannot operate on auto-pilot. As such, these programs will require a human to operate the host computer to enable a remote connection.
• Unattended programs can be setup to run automatically and continuously on a computer so that it can be accessed remotely anytime.
• Remote Procedure Call (RPC) programs. The RPC protocol is a programming code which allows computer software to access services hosted on a different computer. Users of RPC-enabled programs also usually host their own proxy servers.
• Remote PC access programs may also be categorized according to function: some programs allow only the access and transfer of files from the host computer. The other type, meanwhile, allows complete access and control of the host computer, including its applications and programs.
• A new type of remote access is the web-based service, which allows users to access remote files from any mobile device or computer that has a browser and internet connection. The files are hosted in a remote client server. These type of services are usually subscription-based and renewable every few months or so.
Aside from program type, a key consideration for using remote access is the type of network connection it uses, particularly as most remote clients and servers are now hosted via the internet. Most programs recommend the use of faster speed connections for remote PC access, such as broadband or wireless connections, to minimize the possibility of transfer or network errors.
Also, connection security is a primary concern in choosing the right software. Allowing remote access puts the host computer at risk from third-party intruders who can take advantage of the connection to plant malicious malware and spy on the user’s files. Thus, a good program should have a server with a secure connection.
Choosing the perfect program will still depend highly on a user’s needs and the type of work to be done over remote PC access. These are only the common software types which offer different remote access services, and the key considerations a prospect user should know before making their choice.
