Main Frame

Refers to a computer is used to place the mainboard and other major parts of container. Usually includes CPU, memory, hard disk, cd-rom, power supply, and other input/output controller and interface.

Host overview

1. The mainframe computer

Refers to a computer is used to place the mainboard and other major parts of container. Usually includes CPU, memory, hard disk, cd-rom, power supply, and other input/output controller and interface, such as USB controller, graphics, network adapter, sound card, etc. Located in the mainframe, and the often called internal located outside the mainframe box is often referred to as peripherals such as displays, keyboard, mouse, external hard drives, external cd-rom, etc.). Generally, the host itself is already a can independently operating computer system, server has special purpose computers are usually only host, no other peripherals.

Virtual mainframe 2.

Insgroupsto host or hosting services. Provide virtual mainframe or hosting service providers usually have big Internet access the bandwidth (100 Mbps above), so users can provide good exit bandwidth. The user can also through the web host or will own host customer-related to greatly reduce to apply on their own special connection of operation and management costs.

3. Internet hosts

Internet hosts: and Internet linked to any computer are called the mainframe, each machine hosts are a unique IP address, each machine hosts on the Internet status are equal.

Mainframe computer components

1, case (load host accessories box, no case does not affect use)

2, the power supply (host power supply system, no power cannot use)

3, boards (connect hosts various parts of the subjects, not the mainboard host cannot use)

4, the CPU (host heart, be responsible for data operation indispensable.).

5, memory (storage host calls files, indispensable.

6, hard disk (host memory, independent host indispensable)

7, sound card (some motherboard integration)

8, video card (some motherboard integration)

9, nic (some motherboard integration, no nic computers cannot access the network).

10 and cd-rom (no drive, host cannot read disk file)

11, floppy disk (no floppy disk, the host cannot read floppy disk file)

12, some not commonly used equipment such as: 1394 card, video capture card, TV card, bluetooth etc

Virtual host

What is a web host?

1, network space - also called web space, are stored web, procedures, pictures, etc. The main page document space,

2, database space - support database of virtual console provided database storage space,

3, log space - web logs (log) file storage space.

Virtual mainframe, (also called web space) is on a web server disk space differentiate to certain users, applications for site module, and provide the necessary site function and data storage and transmission function.

Virtual mainframe technique appears on the Internet technology, is the major contribution, is broad Internet users of the Gospel. Because many sets of virtual mainframe sharing a real mainframe resources, each user susceptive hardware expenses, network maintenance cost and communication lines of costs are greatly reduced, the Internet really become everyone with a network! Now, almost all the American company (including some families) are on the network have established their web server, there are quite a part USES is the virtual host!

So-called virtual mainframe, also called the "web space", is an operation on the Internet server was partitioned into several "virtual" of the server, each a hosting are independent of the domain name and complete Internet server (support WWW, FTP, E-mail, etc.) function. A server on the different virtual host is independent, and by the user to management. But a server host only able to support a certain number of virtual mainframe, when more than the quantity, the user will feel performance sharply.

Virtual mainframe technology is the Internet servers server hardware cost saving technology, virtual mainframe technology mainly applies to the HTTP service, will be a server of a certain or full service content logic division for multiple service units, foreign performance for multiple servers, which make full use of the server hardware resources. If the division is system level, it is known as a virtual server.

How to choose the virtual hosting providers

A, operation time length operation time length is to evaluate a virtual mainframe provider of important standard.

Second, whether they have room whether they have a reliable, stable and safe high-speed computer room is the measure of a successful virtual mainframe provider another important standards. In the Internet sector, often appear such circumstance: some company itself has no room, or none machine room, but they are often at below-market prices many price to users commitment various services. It is conceivable that lack sufficient hardware support, technical strength, these commitments often end can only be unrealistic castles in the air. So you can be sure the those even room sites are reluctant to tell the customer companies have is a fraudulent composition of virtual mainframe provider, the vast number of users to cope with these situations keep highly vigilant.

Three, high ratio of performance degradation low lead to low to prevent service provider disappear the excellent credit, excellent quality, sincere service, reasonable price, for a successful virtual mainframe provider, these 1 can't be little.

Four, requirements for online number of customers, and provide trial demo address space, as new vey IDC services such as the offer trial service.

Five, don't cheap to rent a certain customer base of space dealer's host generally, because of its larger scale of service providers in hardware equipment, network resources, security, human resources, business reputation, marketing and other investments are far more than the normal service providers, so the price tend to be high, but the service quality criterion more is guaranteed.

Six, facilitator best can provide mailbox, FTP etc online management functions.

Seven, with particular attention is at present many cheats with household PC do server, use ADSL for access. This kind of space of stability and speed is very poor, remember not greed this petty gain.

Eight, the size of space of virtual hosting spatial capacity assessment virtual host is an important index of performance. Normally, we must also assessment several space capacity size -

Virtual hosting advantage

Cheap, despite online information release possess obvious publicity function advantage, but the cost is low still is unthinkable. Radio and television advertising although in seconds calculate, but also cost frequently hundreds of thousands, newspaper AD also costs a lot, beyond most unit individual endurance. Online information release due to save newspapers of printing and radio and television expensive production costs, charges reduced greatly, make most unit individual may inherit. Bestrow scope, the traditional media, newspapers, broadcasting television whatever light-box posters all can't cross or regional limits and only to specific areas influenced. Clinch a deal for the high probability, traditional media advertising, the audience is mostly passive acceptance, is not easy to produce the result. Form is lively, using multimedia technology, information on the Internet, wen, graph, like a variety of forms such as sound, the shape of the products, purposes, using method, price, buy methods in user information directly before the show. With real-time, the businessman can according to the market's needs to change at any time the contents of advertisements, flexible and convenient. More importantly, for enterprises and institutions concerned, the user to save money, is currently the most convenient and practical way.

The Internet now league has nearly YiTai computers, these computers no matter what they are type, operation, use what what operating system software, can be classified into two categories: client and server.

The client is visit other information machines. When you through the post office or other ISP's dial-up, your computer will be temporary assigned a IP address, using this temporary id card, you will be in the Internet in an ocean of information, when you break line, your computer from the Internet's IP address also be retrieved.

The server is to provide information to let others to have access to the machine, are often called the host. Because people ever access to it, so as the main engine must zhongsheng connected on the Internet, have their own permanent IP address. This not only to set up special computer hardware, still have to hire expensive DDN, plus various maintenance cost such as rent, artificially, electricity, etc, is not good bear. Therefore, the people developed virtual host system.

Using virtual host system, can put a real host into many "virtual" the host, each one virtual host are independent of the domain names and IP addresses, with complete Internet server functions. Virtual mainframe between full independence, in the outside world view, each one virtual host and a separate mainframe exactly the same. As well, but the cost is not the same. Because many sets of virtual mainframe sharing a real mainframe resources, each virtual mainframe users susceptive hardware expenses, network maintenance cost and communication lines of costs are greatly reduced, the Internet really become everyone with a network!

At present, many enterprises to establish websites are using this method, thus not only saves much buys machine and leased line cost, also do not have to use and maintenance of server technology problem, needless to employ special management personnel.
