Computer Server

What is a Server?

A server is a computer program that distributes services to other computer programs (and their users) in the same or other computers. The machine that a server program runs in is also frequently referred to as a server. That computer may be a dedicated server or used for other uses as well.

In a technical way, a server is an instance of a computer program that accepts and responds to requests made by another program, known as a client. Presently, any device that runs server software could be considered a server as well. Servers are used to manage network resources. E.g. A common user may setup a server to control access to a network, send/receive e-mail, manage print jobs, or host a website.

Server Categorization/Types of Server:

Servers are usually categorized in terms of their purpose. Here are some Servers as below:

  • Application server
  • Blade server
  • Cloud server
  • Database server
  • Dedicated server
  • File server
  • Print server
  • Proxy server
  • Standalone server
  • Web server

There are some common types of servers that are implemented on a network:

Type

Description

File server

Stores network users’ data files.

Print server

Manages the printers that are connected to the network and the printing of user documents on the network printers.

Communications server

Handles many common communications functions for the network, such as e-mail, fax, remote access, firewalls or Internet services.

Application server

It shares network-dedicated versions of common application software and terminates the need for software to be installed on each workstation.

Database server

Manages common databases for the network, handling all data storage, database management and requests for data.

Domain server

It authenticates and authorizes machine and users to access resources within the logical domain.

Server Specification:

  • Operating System: Windows 7,8,10 or later, Server 2008, 2010, 64 bits (PC or Mac computers using Boot Camp).
  • Ram: 8GB recommended but you can use 16 GB for better performance.
  • Processor: Any CPU (Intel i5/ i7/ Xeon recommended).
  • Graphics: Any GPU that is compatible with OpenGL 3.2. (Integrated graphic cards Intel HD 4000 or above).
  • Hard disk(SSD):
    • Mini Projects (under 100 images at 14 MP): 4 GB RAM, 10 GB HDD Free Space.
    • Medium projects (between 100 and 500 images at 14 MP): 8 GB RAM, 20 GB HDD Free Space.
    • Megaprojects (between 500 and 2000 images at 14 MP): 16 GB RAM, 40 GB HDD Free Space.
    • Very Large projects (over 2000 images at 14 MP): 16 GB RAM, 80 GB HDD Free Space.
  • Note:
    • An SSD hard drive can speed up processing.
    • The graphic card may have an enhancement on the processing speed (if the graphic card is compatible with CUDA (NVIDIA Graphic Cards). Processing time is not affected by the GPU. The GPU affects considerably the visualization of the ray Cloud.

Server Location: Where My Server is physically located! Is that matter?

It’s good to know that every byte that can be found on the internet, is physically hosted somewhere. There’s a machine somewhere in the world that has that particular piece of information on it, and it’s sharing it with everyone else.

Why do we like this?

Being businessmen, they searching for, get the most for their money are worth, so it’s quite natural why these entrepreneurs are considering the option of hosting their websites abroad. Besides some country has the best internet connection. Maybe not the fastest, but it has over 50 I.S.P’s. Amazing, Right?

When it comes to S.E.O, it’s recommendable that you keep your servers as much as close.

Google ranks on loads of various factors. The Geo-IP location of my server is one of them, but it’s certainly not the most important one.

Geographical location of the server matters only in a routine sense. It has outcome only on the number of hoops that it takes for some piece of data to move around. The little hoops it uses, the faster your information will move around.

If it’s about uploading videos and distributing video, and playing real time games, speed and stability is something that you should be looking for in a network.

Effective Server Response:

  • The time delayed between the input and the output signal which depends upon the value of passive components used is known as Response of server.
  • The time a generic system or functional unit takes to react to a given input is known as Response Time.
  • How quickly an interactive system responds to user input is called Responsiveness.
  • Time to response the search or query response time, the time it takes a web server to respond when it receives a query.

These are must have to be minimal as per optimization.

Bandwidth:

Bandwidth is the bit-rate of accessible or consumed information capacity expressed typically in metric multiples of bits per second. Although, bandwidth have been characterized as network bandwidth, data bandwidth, or digital bandwidth.

  • Network bandwidth: It’s usually calculated in bits per second (bps); modern networks typically have speeds measured in the megabits per second, or Mbps or Gigabits per second, or Gbps
  • Data bandwidth: It’s the amount of data that can be transferred at one time.
    Data bandwidth is the actual amount of data transferred.
  • Digital bandwidth: It’s the number of pulses per second measured in bits per second (bps). For example, Ethernet transmits at different speeds, including 10 Mbps, 100 Mbps and 1000 Mbps (see Mbps and baseband).

How it affects your website?

The lacking of your bandwidth is less, the faster it takes your website to load, regardless of your visitor’s connection type. Visitors will have to wait their turn. The lacking of your data transfer is less, the more often you will find your website available because you have reached the maximum data allowed to be transferred.
