A server refers to a device or computer on a network that handles the resources within a network. Various types of servers are; a database server processes database questions, a print server manages printers, file server handles file storage, and a network server handles network traffic. Servers have the strength and power to utilize more than one user at a time. Computer hardware is an object that one can touch physically such as; chips, boards, keyboards, display screens, disk drives, and disks.
Components of a computer server
A server computer has similar hardware components as those found on any desktop computer that performs simple tasks. However, desktop computers are not built using high-grade hardware like the server computers, or cloud servers. The components of a server computer include;
- Motherboard. The motherboard is the main circuit of the server’s electronic board, where all the computer components are connected. The computer, in essence, is the motherboard. The components of the motherboard include; a chipset, a standard IDE hard drive controller, memory, the CPU, expansion slots, and input/output ports for use of devices like the mouse, keyboard, and printers. Some motherboards have in-built features like a network interface, SCSI disk controller, and a graphic adapter.
– Power supply. Unlike desktop computers a server has many devices, and this means more power is required within the range of 300 watts, and above.
– Video. In order to cut costs when using a server, a business can use generic monitors or video cards without affecting the performance of the network.
– Network connection. This is the most important part of a server. Almost all servers are fitted with network adapters at the motherboard.
– Hard drives. Performance is key to servers, therefore; it makes use of a type of drive known as SCSI, which comes with a high-speed SCSI controller card. SATA desktop computer drives are used by server computers for their performance and reliability.
– Memory. One has to pick the appropriate memory that is supported by the motherboard. Recent servers now come with 32GB of memory.
– Processor. Also known as the CPU, the processor is the computer’s brain. This is the part most people consider before selecting a server type, examples include; the Pentium 4 with 1processor core with a clock speed of 2.4-3.6GHz; the Pentium D with 2 processor cores with a clock speed of 2.6-3.6 GHz. Processor cores affect performance as each core acts as a separate processor. Most server computers come with four, or two processor cores. Each motherboard is compatible with a certain processor type, and the server computer ones come with more than one socket, or slot to hold separate CPUs.
- Cloud servers. A VPS which is dynamic (can be changed at runtime) is often referred to as a cloud server. It offers additional hardware resources like CPU and RAM.
