Discuss about Computers for Individual Users.

Ans:-

          Most Computers are meant to be used by only one person at a time. Such Computers are often shared by several people. But only one user can work with the machine at any given moment. The five primary type of Computers in this category are 

Computers for Individual Users

• Desktop computers
• Workstations
• Laptops
• Network Computers
• Hand held Devices

Desktop computers:-

                                      A desktop computers is the most popular model of PCs. The system unit of the desktop PC can be placed flat on a desk or table. It is widely used in homes and offices.

Workstations:-

                           A workstation is a specialized, single user computer that typically has more powerful than a standard desktop PC. These machines are popular among scientist, engineering's and animators who need a system with greater than average speed and the power to perform sophisticated tasks. Workstations often have large, high resolution monitors and accelerated graphics handling capabilities, making them suitable for advanced architectural or engineering design, modeling, animation and video editing.

Laptops:-

                 Laptops are very handy and can easily carried from one place to another. They m hiay also be placed on the user's lap. Hence, laptops are very useful, especially when going on long journeys.

Laptops operate on a special battery and do not always have to be plugged in like desktop computers. The memory and storage capacity of a laptop is almost equivalent to that of a desktop computers. As with desktop computers, laptops also have a screen, keyboard and a trackpad or trackball, which serves as the mouse. These computer are very popular among business travelers.

Network Computers:-

                                       A Computers With minimal Memory, disk storage and processor power designed to connect to a network, especially the Internet. The idea behind network Computers is that many users who are connected to a network don't need all the computer power they get from a typical personal computer. Instead they can rely on the power of the network servers.

Hand Held Computer:-

                                         Handheld personal Computers are computing devices small enough to fit in your hand. Some examples of handheld computers are:

• Personal Digital Assistant (PDA)
• Cellular phones
• H/PC pro Device.

A popular type of handheld computer is the personal Digital Assistant PDA, A PDA is no longer then a small appointment book and is normally used for special applications, such as taking notes, displaying telephones numbers and addresses, and keeping track of dates or agendas.

Cellular phones are web enabled telephones that have features of both analogue and digital devices. Such phones are also known as smart phones. Because, in addition to basic phone capabilities, they also support access the internet and send emails and faxes.

H/PC pro Devices is the new development in handheld technology. The size and features of the H/PC pro Device is more than PDAs but less than that of typical notbook PCs. The H/PC pro Device includes a full sized keyboard, RAM with very low storage capacity, and a slow speed processor these Devices do not have a secondary storage disk.
