Computer Performance

Image
 Computers and laptops are very expensive. So in buying one, the customer must choose the best one for him/her. Computers are very helpful with school or work. That is why even if it is very expensive, people still buy them. It is one of those gadgets that have become part of our lives, just like those mobile phones. A lot of people own computers because it is very useful. You can do a lot of things with it, for both work and leisure . Since we use it for a lot of things, the customers must make sure that the computer that they buy has a good computer performance. Since they spent a lot of money , they should be able to use for a long time and they will be satisfied with it. There are different brands and models that are being sold in the market but what are the factors that people look at when they are buying computers? Of course, most people check for the brand. They would rather buy those popular brands because they know that a lot of people get this kind of brand. A lot of buy

What Are Junk Files on the Computer?

Image
 After the computer is used for a period, you must have the feeling that it can't run as fast as the beginning, which is because in its hard disk, many junk files have been accumulated. All the work you do with a computer, such as install and remove software or surf the internet, will leave junk files on the computer. And much hard disk space has been occupied by them so that the computer runs slower and slower. Then what are junk files on the computer? 1. The Temporary File Which Is Produced When You Install a Software Application. When a software application is installed, it will unzip its installation file to a temporary directory first, usually the temp directory under the folder of Windows. If the software is designed with some bugs or the operating system is not so perfect, temporary files will become junk files on the computer permanently. They often exist in the form of *.tem. 2. The Temporary File Which Is Produced by the Running Software. The same with the installing p

Hardware - The Concept of Hardware and Electronics

Image
 Hardware refers to computer chips, circuit boards, computer systems, and related equipment such as keyed equipment such as keyboards, modems, and printers. The work of computer hardware engineers is very similar to that of electronics engineers, but unlike them, computer hardware engineers work with computers and computer-related equipment exclusively. Hardware jobs include production and service engineers, R&D and maintenance engineers. Most trained engineers are employed by the computer equipment manufacturers. For this job, a very specialized training is required and that can only be acquired in postgraduate course of computer engineering and technology. A diploma in a specialized branch of engineering with special emphasis on training for specific jobs and work experience may be adequate as qualifications only for some jobs. Technology related to computers is changing very rapidly; hence there are exciting challenges for the computer professionals in hardware. They can lear

About Computer Generations

Image
 Computer is an electronic device used to accept the data in the form of digitalized (binary 0 and 1) to perform some task based on the sequence of instructions program. Five generations of computers, First generations of computers (1940-56) operated in vacuum tubes. Computers use the vacuum tubes for circuitry and magnetic drums for memory. The drum rotates at a speed of 3000 rpm. This computer is very expensive to operate and it wants more electric power and it produces a lot of heat. First generations of computer understood machine level language, lowest level programming language to perform the operation. Input of the system is punched cards and paper tape and the output was displayed only on printers. Disadvantage, It requires more space Very expensive to operate It needs more power Second generation computer (1956-63) transistors replace the vacuum tubes. Transistors are devices that consist of semiconductor material that amplify the signal. Transistors eliminate the disadvantage

Networking Trends

Image
 The earliest micro Local Area Networks were easy to install. Telephone wires were strung between the micros or coaxial cable was installed behind a wall. Each micro needed a Local Area Network adapter card on its main bus, which translated requests into network packets and vice versa. These early networks were used primarily to share devices such as laser printers and plotters. The network software was installed on a micro that was hooked to the shared devices. This machine becomes known as the server. The next logical step was to allow users to share data. Early implementations transferred data as complete files. When a user requested information from a file, the whole file was sent over the network to their machine. The file was locked and was not available to any other user. Software advances modified the procedure so that files were accessed for query only, thereby not locking other users out. However, complete files were still sent over the network, Software advances have now tak

Slow Down, Driver

Image
 We've all had this happen. You get a shiny new accessory for your computer; a printer, a scanner, a webcam, or whatever else. You hurry home, tear open the packaging leaving a trail of cardboard between the door and your computer. You fire everything up, plug the new toy into your PC and... nothing. No sign of life other than the power light. Your new <insert device name here> isn't working. You're having a driver issue. Most people only vaguely understand what a driver is, or what it does. Basically, a driver (or device driver) is a file or set of files that provide an instruction manual to the computer. Drivers tell your computer what's connected to it, and how to talk to that particular device. Nowadays, Windows has a lot of drivers built into it, so it can recognize more and more devices with each new version. But there will always be devices that are too new or too sophisticated for built-in drivers. Manufacturers provide discs with the drivers on them, but
