Tip 1: Can I work on the computer during defragmentation?
The hard drive is jammed with information, the computerslows down and the user enables defragmentation. But the rush, the unfulfilled plan, the unfinished letter or the unfinished report force again and again to "torment" the PC, despite the fact that it is on prevention. Defragmentation and simultaneous work - compatible in incompatible.
Service to work does not tolerate fuss, but not when"The report burns", came "deadline" and it is necessary to have time as much as possible in as little time as possible. And here comes the realization that it's high time to perform the defragmentation procedure, so that the PC is a little bit faster.
What is defragmentation?
Information on the computer is recorded unevenly on the hard disk. It is randomly allocated to free sectors and clusters.Defragmentation is best done regularly, and to do this, create a task in the Operating System.This state of affairs sooner or later leads toThe reading heads slowly find the part of the disk that is needed. At a visible level, this is reflected in the so-called "brakes". The operating system "digests" the request for a long time and can not give out the desired result as quickly as an impatient user wants. In this case, you need to defragment to organize the data.
An impatient user's syndrome
When the computer is busy with defragmentation, hardthe disc is loaded very much. The reading heads have to work in complex mode. Find information, read it, rewrite it to a new location to make it orderly. At such moments, ideally, it's best to leave the PC alone and do something else.Impatience is not a flaw for the user, but when you work during defragmentation, slow down the process even more.But, as you know, there is no ideal. In the real world, when a defragmentation takes a couple of hours, which is not uncommon, the user can not stand and start working until all the required operations are completed. And there is nothing wrong with this, if you reconcile yourself with the overall slow operation of the system. Hard drive read heads have to spend time organizing information, as well as fulfilling your requests. This is expressed in the slow opening of files, "stuttering" audio and "brakes" video. You can not lose information in this way, unless there is an abrupt voltage jump during defragmentation. It's good if you have more than one hard drive on your computer. Then you can work with files on one disk, and defragment another. Then, if possible, transfer information to the first disk, and run the second on defragmentation. This will somewhat reduce the time loss and speed up the overall process. Therefore, if you have the option, do not prevent the computer from making the system faster and do not disconnect it before the operation is completed. Defrag on the night and calmly go to sleep. If the work does not tolerate, you can perform various actions simultaneously with the maintenance of the PC. Strict prohibitions can not be here, but simply recommendations.
Tip 2: Getting Started on Your Computer
The personal computer has firmly entered intoeveryday life of almost every person over 9 years old. Specialists, students and schoolchildren "smart machine" is necessary for work and leisure. But before you sit down at the computer, each newcomer needs to learn how to use it.
You will need
- A computer,
- student allowance.
Instructions
1
If you feel like working on a computerit is very difficult and for the beginning it is necessary to pass some courses, this is not entirely true. Registering for paid group lessons, you will be taught basic rules for using a PC: how to click the mouse, set the command with a keyboard shortcut and so on ... These courses take about two weeks at the rate of one lesson - one hour (or two academic). classes will give you a crust on the passage of computer literacy courses. But you can really learn how to work with this technique only when no one prompts or does the simplest actions for you.
2
If you really want to learn how to communicate withcomputer on "you" and do not get lost in all the varieties of opportunities that are opening up, we strongly recommend that you purchase a textbook. The book will cost much less. In addition, the student allowance does not require time spent on the journey to the training center and back. All the books that are now on the thematic shelves of stores are written in a simple and easy enough language. Introduction to computer literacy is measured and measured in them, you will master the basics of working with PC gradually, step by step. If you sit in front of a home computer with a book, you will achieve excellent results in about the same time period that you will spend at public courses.
3
Unlike paid lessons, the book is a one-piecemethodological material that has been worked out by a team of specialists and, as a rule, approved by a special commission under the Ministry of Education. The printed manual will not reflect the emotions of the author, his bad mood, boredom from the monotony of his work, etc. In addition, the book will always be at hand, at the time you want, anywhere.
Tip 3: Do you need programs to defragment the drive
On the Internet we are often offered to download any"optimizers," "cleaners," and "defragmenters." All who use them, intuitively notice that they bring a little benefit. Today I'll tell you why you do not need a program to defragment the disk, if you have Windows 7 or 8.1.
You will need
- Computer with Windows 7 or 8.1
Instructions
1
To begin with, if you have an SSD drive, defragmentation for it is generally harmful. This accelerates its wear and tear, but it will not bring any benefit. You can safely forget about defragmentation forever.
2
If you have Windows 7, then you need to know what's in theThis version of the OS is defragmented once a week on a schedule. Check how long the job is set. Suddenly it is done at night, and the computer is turned off.
3
In Windows 8.1, defragmentation is performed automatically in the background. Or when you are not working on the computer, and it is idle. No action is required from you. And if Windows still does not do the defragmentation on a schedule, after three passes it will force you to do it.
Tip 4: How the first computer worked
In 1996, many countries of the world celebrated the 50th anniversaryinformatics. This event is associated with the 50th anniversary of the creation of the first Eniac computer. No computer has had such a big impact on the development of digital technology, like Eniac.
Instructions
1
The first Eniac computer was created in the USA in 1946year. The authors of the project were the scientists John Mockley and J. Presser Eckert. The group of developers included John von Neumann, who formulated the principles of the computer. Modern computers are designed in accordance with these principles.
2
According to the principles formulated by Neumann,the computer must consist of an arithmetic-logical device, a program execution control device, a memory device, an information input-output device.
3
The first electronic computer Eniacwas created at the request of the US Department of Defense to solve ballistic problems. Computer Eniac was able to solve many tasks not only in the military industry. The first successful numerical weather forecast was made with the help of Eniac in 1950.
4
The computer had a small amount of internal memory,which was sufficient only for storing numerical data. Software for calculations had to be practically "soldered" into the electronic circuits of the machine. The program was set by a circuit for switching triggers on 40 dial fields, so the machine was reset for weeks. The first computer used a decimal number system (in modern computers a binary system is used). By its structure, the first computer was analogous to a mechanical computer.
5
Eniac computer used three typeselectronic circuits: coincidence circuits, collective circuits and triggers. The signal at the output on the coincidence circuits appeared only in the event that signals were input to all the inputs. In collective circuits, the output signal appeared in the event that there was a signal at least on one input. Triggers were made on double triodes - two three-electrode tubes were mounted in one cylinder.
6
Use of electrovacuum technologyallowed to achieve speeds that are not available with the use of electromechanical elements. The Eniac computer could perform 5,000 addition operations and 360 multiplication operations per second. Mechanical and electromechanical arithmometers made calculations hundreds of times slower.
7
The weight of the machine was 30 tons. The area occupied by the first computer is 300 sq.m. In the design of the first computer, 17,468 electronic tubes were laid. This was due to the fact that Eniac was created to work with decimal numbers. However, such a number of lamps led to overheating and breakdown. In 17 thousand lamps every second there were 1.7 billion conditions under which one of the lamps could not work.
8
The developers solved this problem as followsway - the electronic lamps began to apply less voltage, and the number of emergencies decreased. J. Eckert became the author of the program for monitoring equipment malfunction. Each component of the first computer was carefully checked and sealed in the right place.
9
The first computer Eniac worked 9 years from the moment of creation. The last time it was included in 1955.
Tip 5: What is Disk Defragmentation?
Windows Operating System Speedgradually decreases under the influence of various factors, one of which is the disparity of files on the hard disk. Disk defragmentation helps to solve this problem.
What is the need for defragmentation?
Defragmentation is a processoptimization and updating of the logical structure of disk partitions for ordering files with a continuous sequence of clusters. Defragmentation allows you to speed up the reading and writing of files, which increases the speed of various programs and the entire operating system. This is due to the fact that the write and read operations are performed at a higher rate than random accesses. In a more simplified form, defragmentation is an operation to redistribute files on a disk in such a way that they are located in continuous areas. Large files occupy several clusters. When recording on an unfilled disk, the clusters belonging to the same file are written in succession. A crowded disk does not have solid areas sufficient to accommodate the file. However, a file entry is still made if the disk has several small areas sufficient to record the total size. The file in this case is written as several fragments. Splitting the file into fragments during the recording is called fragmentation. If there is a large number of fragmented files on the disk, the speed of media reading is reduced, because it takes time to search for files containing clusters. If you compare it with other media, for example, flash memory, the search time on them does not depend on how the sectors are located, so fragmentation on them practically does not occur. Some software needs to ensure that the files are necessarily stored in sequentially sectors (to For example, this requirement imposes a built-in emulator in the Zalman VE-200 drive for image files). The need for defragmentation in this case will not save even the installation of a solid-state drive.How to defragment
Defragmentation is necessary at suchfile systems, such as MS-DOS and Microsoft Windows, because the programs they support do not protect the system components from fragmentation. It can even begin on an almost empty disk with a small load. Defragmentation is performed using special defragmenter programs that are available among pre-installed applications in the system and are able to literally collect files from their fragments. The only drawback is the low speed of the operation: waiting for the defragmentation to finish sometimes takes several hours.Tip 6: How to make your computer run faster
How nice, when a computer works quickly. Almost instantly, programs are loaded, games are not slowed down. But there are periods when a computer reduces its efficiency. Its performance catastrophically falls down. Therefore, it is urgent to take measures to return fast work a computera.
Instructions
1
The main reason for the slowdown a computerbut lies in its software. There is a contamination of the registry by unnecessary and already deleted files. The fragmentation of the disk increases. Increasingly, unnecessary programs are installed and their removal is incorrect. A huge number of processes. Viruses can also penetrate into the system and disrupt the operability a computera.
2
Perform full ordering of files and folders in the system. Eliminate the rubble, dismantle the folder with "junk". Remove any unnecessary programs. Install Optimization Programs a computera. With their help, clean the registry. Then defragment it. This operation can be performed several times to increase useful work. After the registry, try defragmenting the hard disks. So you can improve performance on them. At the very end, perform an anti-virus scan.
3
Improve your a computer by purchasing new equipment. The more you load your a computer, the more resources are required. Acquire the processor more powerful, install a couple more gigabytes of RAM. An obsolete power supply can also cause slow system operation.
