Just think of what happens when the worksheet you’ve been using for your financial account balances suddenly gets corrupted. If you don’t have an electronic copy of the information, then you will be stuck with re-entering all of the information again. It’s important to have a printed copy of a record or file, but it’s also important to have a back-up of the actual computer file. With home computer instruction you can get the skills to be familiar with how to best back-up your documents, which files to back up, and what utilities can best reach your desires. Next look at a couple of areas that often get ignored while the PC slows so much it is basically at a standstill. Your slow computer may be caused by the need of a disk cleanup and file fragmentation. Home computer training will help the new computer user understand how to recognize when a computer memory is becoming cluttered, and what to do to prevent it.

Networks, and the internet, don't identify computers (of any size, even your smartphone) by the name you give them. Computers prefer numbers, and the numbers they use as identifiers are called IP addresses. The "IP" stands for "internet protocol," which is part of the Transmission Control Protocol/internet Protocol (TPC/IP). It's all called IP for short, and TCP/IP is the language used for communication by most networks. When it comes to your computer(s), there are actually several IP addresses involved. One is how the computer talks to the internet at large, which is the IP address of your router. That IP address is generally assigned to the router by your internet service provider (ISP); the router, in turn, handles all the traffic from your computers and other devices out to the internet. So even though a website only sees a request come in from the IP address on the router, the router knows how to route the information to/from the computer. That way, all the nodes on the internal network can communicate. This artic le has been c re ated by G SA Content Generator Demoversion !
A desktop computer is a personal computer designed for regular use at a single location on or near a desk due to its size and power requirements. The most common configuration has a case that houses the power supply, motherboard (a printed circuit board with a microprocessor as the central processing unit, memory, bus, certain peripherals and other electronic components), disk storage (usually one or more hard disk drives, solid state drives, optical disc drives, and in early models a floppy disk drive); a keyboard and mouse for input; and a computer monitor, speakers, and, often, a printer for output. The case may be oriented horizontally or vertically and placed either underneath, beside, or on top of a desk. Prior to the widespread use of microprocessors, a computer that could fit on a desk was considered remarkably small; the type of computers most commonly used were minicomputers, which, despite the name, were rather large and were "mini" only compared to the so-called "big iron".
Server usually refers to a computer that is dedicated to providing one or more services. A server is expected to be reliable (e.g. error-correction of RAM; redundant cooling; self-monitoring, RAID), fit for running for several years, and giving useful diagnosis in case of an error. For even increased security, the server may be mirrored. Many smaller servers are actually personal computers that have been dedicated to provide services for other computers. A database server is a server which uses a database application that provides database services to other computer programs or to computers. Database management systems (DBMSs) frequently provide database-server functionality, and some database management systems (such as MySQL) rely exclusively on the client-server model for database access while others (such as SQLite) are meant for using as an embedded database. Users access a database server either through a "front end" running on the user's computer - which displays requested data - or through the "back end", which runs on the server and handles tasks such as data analysis and storage.
