COMPUTER SYSTEM SERVICING
It is any part of your computer that has a physical structure, such as the computer monitor or keyboard.
Hardware
It is any set of instructions that tells the hardware what to do. It is what guides the hardware and tells it how to accomplish each task. Some examples of software are web browsers, games, and word processors such as Microsoft Word.
Software
It is is an electronic device that accepts data, processes it, stores, and then produces an output.
Computer
These are almost extinct today. These are different from a digital computer because an analog computer can perform several mathematical operations simultaneously. It uses continuous variables for mathematical operations and utilizes mechanical or electrical energy.
Analog Computer
They use digital circuits and are designed to operate on two states, namely bits 0 and 1. They are analogous to states ON and OFF. Data on these computers is represented as a series of 0s and 1s. Digital computers are suitable for complex computation and have higher processing speeds.
Digital Computer
These computers are a combination of both digital and analog computers. In this type of computers, the digital segments perform process control by conversion of analog signals to digital ones.
Hybrid Computers
Large organizations use mainframes for highly critical applications such as bulk data processing. Most of the mainframe computers have the capacities to host multiple operating systems and operate as a number of virtual machines and can substitute for several small servers.
Mainframe Computers
In terms of size and processing capacity, minicomputers lie in between mainframes and microcomputers. Minicomputers are also called mid-range systems or workstations. The term began to be popularly used in the 1960s to refer to relatively smaller third generation computers.
Minicomputers
They are computers designed to provide services to client machines in a computer network. They have larger storage capacities and powerful processors. Running on them are programs that serve client requests and allocate resources like memory and time to client machines.
Servers
The highly calculation-intensive tasks can be effectively performed by means of supercomputers. Quantum physics, mechanics, weather forecasting, molecular theory are best studied by means of supercomputers. Their ability of parallel processing and their well-designed memory hierarchy give the supercomputers, large transaction processing powers.SupercomputersA computer with a microprocessor and its central processing unit it is known as a microcomputer. They do not occupy space as much as mainframes do. When supplemented with a keyboard and a mouse, microcomputers can be called personal computers.MicrocomputersIt is intended to be used on a single location. The spare parts of it are readily available at relatively lower costs. Power consumption is not as critical as that in laptops. They are widely popular for daily use in the workplace and households.Desktop ComputersSimilar in operation to desktops, laptop computers are miniaturized and optimized for mobile use. It runs on a single battery or an external adapter that charges the computer batteries.LaptopThey fall in the category of laptops, but are inexpensive and relatively smaller in size. They had a smaller feature set and lesser capacities in comparison to regular laptops, at the time they came into the market.NetbookIt is a handheld computer and popularly known as a palmtop. It has a touch screen and a memory card for storage of data. They can also be used as portable audio players, web browsers and smart phones. Most of them can access the Internet by means of Bluetooth or Wi-Fi communication.Personal Digital Assistant (PDA)They are mobile computers that are very handy to use. They use the touch screen technology. It comes with an onscreen keyboard or use a stylus or a digital pen. Apple's iPod redefined the class of tablet computers.Tablet ComputersThese computers can be worn on the body and are often used in the study of behavior modeling and human health. Military and health professionals have incorporated wearable computers into their daily routine, as a part of such studies.Wearable ComputersMany of it can do a lot of things a computer can do, such as browsing the internet or playing games. They are often called smartphones.Mobile PhonesMany of it now includes applications (or Applications) that let you access various type of online content. For example, you can view Facebook news feed or watch streaming movies on NetflixSmart TV
