A computer system consists of two major elements: hardware
and software. Computer hardware is the collection of all the parts
you can physically touch. Computer software, on the other hand, is not
something you can touch. Software is a set of instructions for a computer to
perform specific operations. You need both hardware and software for a computer
system to work.
Some hardware components are easy to recognize, such as the
computer case, keyboard, and monitor. However, there are many different types
of hardware components. In this lesson, you will learn how to recognize the
different components and what they do.
➡️Server⬅️
In a technical sense, a server is
an instanceof a computer program that accepts and responds to requests
made by another program, known as a client. Less formally, any device that
runs server software could be considered a server as well. Servers are used to
manage network resources. For example, a user may setup a server to
control access to a network, send/receive e-mail, manage print jobs, or host a
website.
Some servers are committed to a specific task, often
referred to as dedicated. As a result, there are a number of dedicated server
categories, like print servers, file servers, network servers, and database
servers. However, many servers today are shared servers which can take on the
responsibility of e-mail, DNS, FTP, and even multiple websites in the
case of a web server.
Because they are commonly used to deliver services that are
required constantly, most servers are never turned off. Consequently, when
servers fail, they can cause the network users and company many problems. To
alleviate these issues, servers are commonly high-end computers setup to
be fault tolerant.
