Uses of Computers and Some Important Components

Uses of Computers and Some Important Components – IDNSlot Depo Dana Computers are a manifestation of today’s technological developments. With the development of the times, computers have also gone through several evolutions. Starting from the physical form to the components in it underwent an extraordinary evolution.

Every company already uses a computer for its operating system. The convenience provided by computers makes it easier for employees to work. Routine maintenance is also carried out by the company to maintain computer performance so that it does not decrease.

One of the most important computer components is RAM. Random Access Memory (RAM) has characteristics that live up to its name. In accessing data stored in memory, it is done randomly and not sequentially as in a streamer. This means to access memory elements located anywhere and accessed at the same time.

RAM types

  • Static RAM

Internally, each cell that stores n bits of data has 4n transistors that make up several flip-flop circuits. With the characteristics of this Flip-Flop circuit, the data stored is only in the form of On (High state) or Off (Low state) which is determined by the state of a transistor. Its speed compared to Dynamic RAM is of course higher because it does not require a refresh signal to maintain memory contents.

  • Dynamic RAM

Internally, each cell that stores 1 bit of data has 1 transistor and 1 capacitor. This capacitor keeps the voltage flowing through the transistor so that it can still store data. Because current maintenance must be done every few moments (which is called refreshing), this process takes more time than the performance of Static RAM.

As stated earlier, the memory module develops in tandem with the development of the processor. This type of DRAM is also experiencing development.

RAM is also a computer component that works like memory. Having a usage quota limit, requires us to pay attention to the use of RAM on our computers.

Viruses on Computers and Antivirus

Now that everything’s online, there are many things we can do with the internet, from chatting with long distance friends, social networking, watching movies, and listening to music. Along with the increasing number of internet users, more and more new online threats have emerged such as phishing, malware, adware, spyware and so on.

If your computer starts showing a decrease in performance, it could be caused by a virus lodged in the computer. A computer virus is a computer program that copies itself, then inserts a copy of itself into another program or document on the computer system. This is what destroys the computer system.

Types of viruses on computers include;

  • Worm

Actually the Worm virus is not too dangerous. However, if left unchecked, it has the ability to multiply quickly, causing your computer’s memory and hard drive to become full. Usually this type of computer virus infects computers that are connected to the internet and have email.

  • Trojans

Just like Worms, Trojan viruses also generally attack computers connected to the internet network and through emails that users receive. This type of computer virus will control and even steal data on your computer.

  • Macro Virus

This type of computer virus tends to attack macro files such as .pps, .xls, and .docm. Generally, macro viruses often come through the emails we receive. So, in order to avoid macro viruses, you are encouraged to be more vigilant and try your best to avoid foreign messages that enter your email.

To eradicate the virus on the computer, we need an effective antivirus application to deal with the virus. There are many good antiviruses to protect your computer from viruses. The names of these applications include Bitdefender, Avast, Avira, AVG, Sophos and other antiviruses.

Maintaining Your Software and Hardware

Hardware Maintenance Tips

The first thing we have to do is take care of computer hardware components. Here I usually do some maintenance such as:

  1. Placing the computer in a place with good air circulation. Necessary to avoid overheating of computer hardware.
  2. Clean the dust that enters and sticks to the hardware components in the casing. 
  3. Using a Stabilizer so that the flow of electricity that enters the Power Supply is always maintained stability. Or better yet, use a UPS (Uninterruptible Power Supply) so that it can keep the computer from losing power suddenly.

With a few simple actions above, ensure your computer hardware has stable performance.

 Software Maintenance Tips

The second thing that is no less important, of course, is taking care of the software or computer operating system. There are several computer maintenance actions in software that we can do, including the following: 

  • Backing up the computer system
  • Install and Run a Computer Scan with Antivirus
  • Perform Windows Update, Update Antivirus and other Software
  • Perform System Optimization.

Privacy Network VPN

VPN (Virtual Private Network) is a connection between an internet network and other private networks through a public internet connection. VPNs are private because they are aimed at more serious security concerns.

VPNs are commonly used by companies, governments, and military organizations to protect their sensitive data while using the network. However, currently the use of private VPNs is also increasing because it can protect the identity and privacy of users when surfing the internet.

VPN’s have interesting functions. Used for a number of purposes, VPN’s are now a feature on devices. VPN functions in accessing computers include;

  • Securing Transactions While Connected to the Internet
  • Covering Browsing Activity
  • Can Access Websites Blocked by Host or ISP
  • Accessing Content from Censored Sites
  • Increase File Download Speed

Generally, when we access a website on the internet, we will be connected to an ISP (Internet Service Provider). All data traffic requests for websites that we access will pass through the ISP server and can be seen by the ISP. IDNSlot Deposit Dana

Seeing how this VPN works, then:

  • ISP will not know the activity of VPN users on internet
  • Visible IP address is the VPN server IP
  • Using WiFi hotspots is safer
  • VPN providers can see the activity of VPN users on the internet

So many discussions about the use of computers and other important components. I hope this article can help you to know more about computers. We hope that this information will pleased you. Good Luck and See You Soon

Due to technological advances and the development of the times, the use of computers has also developed into all aspects of life. Not limited to electronics, computers are now very much needed in other fields.

Benefits of Computers in the Field of Art

In the early days, computers were expected to help humans to do their jobs. Along with its development, computers are now able to do many things in helping human work in many fields including the arts. On this occasion we will discuss the benefits of computers in the field of art.

Art itself is divided into several types of art, including:

  • Drawing Art

In the art of drawing, technology is often used in editing the results of shooting so that it can produce maximum images. For this, we need a computer with a program (photoshop, Coreldraw, etc.) that functions as an editing medium on a computer.

  • Music Art

In the art of music, to make a perfect recording, a recording studio usually prepares a computer to set the tempo, rhythm. Creating rhythm in music is also easier with a computer.

  • Film Art

With the help of computers and computer graphics, making animated films is very easy and fast. In fact, lately more 3-dimensional animated films have appeared than 2-dimensional animated films. Slot Deposit Dana

Use of Computers in the Field of Transportation

The use of computers in the transportation sector, for example computers used to regulate traffic lights. In other developed countries, many trains have been installed with modern navigation tools to replace drivers through the use of satellites and computer systems.

Roads are also installed with various types of sensors that will send messages to the central computer to facilitate control of certain highways. In addition, with a computer, all flight paths at the airport can be programmed with a computer. To fly the plane itself requires and must be equipped with a computer.

Even at certain altitudes the aircraft can be flown automatically with automatic pilot programmed by the computer. Likewise, ticket sales at terminals, airports, and stations can be served quickly using a computer.

Role in Education

One of the main benefits of computers is in the field of education. The computer is a learning tool to improve students’ abilities. Computers are one of the fields of study in the ability that must be possessed by every student. With the provision of computer science since school, children can compete later when entering the world of work. Apart from providing capital to students, one of the skills that is mandatory when looking for work, another benefit of computers is as an opener of horizons. Many access to knowledge using computers. Can open students’ horizons about this world and everything in it.

Such is the role of computers in several other fields. There are many benefits and uses that we can get when using a computer. Work becomes faster and simpler when working on a computer. IDNSlot Deposit Dana

As stated earlier, the memory module develops in tandem with the development of the processor. This type of DRAM is also experiencing development.

DRAM Type Development

  • Synchronous DRAM (SDRAM) is one such example. This SDRAM (which is usually known as SIMM SDRAM) only improves the speed of access to stored data. By synchronizing the speed of this module with the System Bus Frequency on the processor, it is expected to increase its performance. EDO RAM modules can be brought to their top speed at a maximum FSB of 75MHz, while SDRAM can be brought to speeds of 100MHz on the same system. SDRAM is also developed further. Slot Deposit Dana
  1. PC100 RAM
  2. SDRAM developed for 100MHz system bus
  3. PC133 RAM
  4. SDRAM developed for system bus 133MHz
  5. ECC RAM (Error Checking and Correction RAM)
  6. SDRAM developed for the needs of servers that have heavy performance. This type of SDRAM can look for data corruption in the memory cell in question and can immediately repair it. However, the limitation of this type of SDRAM is that only one data cell can be repaired at a time when processing data.
  • Burst EDO RAM (BEDO RAM) is a type of EDO that has Bursting capability. Performance that has been boosted can be 100% higher than FPM, 33% than EDO RAM. Originally developed to replace SDRAM, but because the process is asynchronous, and is only limited to 66MHz, BEDO RAM is practically abandoned.
  • Rambus DRAM (RDRAM) was developed by RAMBUS, Inc., This development became a polemic because Intel tried to introduce PC133MHz. This RDRAM has a narrow data path (8 bits) but its performance cannot be surpassed by other types of DRAM whose data paths are wider than RDRAM, namely 16 bits or even 32 bits. This is because this RDRAM has a sophisticated Memory Controller. Of course, only motherboards that support RAMBUS can use this DRAM, such as the MotherBoard for the AMD K7 Athlon. However, this type of RAM is used by 3dfx, Inc., to speed up the process of drawing full 3-dimensional objects by polygons. An example of a product that uses it is the 3dfx Voodoo4 series.
  • SyncLink DRAM (SLDRAM) was created because to use this RDRAM you have to pay royalties to RAMBUS Inc., this is considered very expensive for motherboard developers. With a speed of 200 MHz, and a maximum bandwidth of 1600MB/sec, it is enough to canvas the development of RAMBUS DRAM.
  • Double Data Rate RAM (DDRAM) was developed because the data transmission needs are very high. This technology is developed based on the transmission of data to and from other terminals via tact signals.
  • Serial Presence Detect (PSD) is an extension of the DIMM that includes an EPROM chip that can store information about this module. This small chip that has 8 pins acts as an SPD in such a way that the BIOS can read all the information stored in it and can equalize the FSB with the working time for perfect CPU-RAM performance.

That’s an explanation of static and dynamic RAM, if there is an error in the explanation, please understand. I hope this article can help you to know more about RAM. IDNSlot Deposit Dana

How VPN Works and Some Functions

IDNSlot Depo Dana VPN (Virtual Private Network) is a connection between an internet network and other private networks through a public internet connection. VPNs are private because they are aimed at more serious security concerns.

VPNs are commonly used by companies, governments, and military organizations to protect their sensitive data while using the network. However, currently the use of private VPNs is also increasing because it can protect the identity and privacy of users when surfing the internet.

VPN Functions

  • Securing Transactions While Connected to the Internet

VPN is definitely one of the features that must be activated, for example, if you use e-banking. Especially when you are out of town and use public internet access, such as wifi and internet cafes.

Data theft will be easier to do if you often use public internet sources. You are required to use a VPN to do any kind of transaction using the internet to avoid this.

  • Covering Browsing Activity

The VPN function is very useful for users who need privacy while browsing. VPN can help to cover up and hide internet activities that users do so that the history of what users have been browsing on the internet will not be detected by others.

  • Can Access Websites Blocked by Host or ISP

You can use a VPN to help keep access to blocked sites.

The function of the ISP itself is to expand the network to users by supporting optimal internet use, protecting against viruses when accessing the internet, and controlling internet access speed for users.

  • Accessing Content from Censored Sites

Some content on the internet also sometimes experiences censorship for some reason by the host and also the internet service provider. By browsing and also accessing the internet using a VPN, you can enter sites that have censored content.

  • Increase File Download Speed

Sometimes a VPN can also work to increase internet speed or speed. You can use a VPN to help increase the download speed of some very large files on the internet.

This is because when using a VPN, the user is like using a private network which is little used by others so that the speed increases. In addition, users can also be connected directly to the flow of data flowing on the internet which of course can increase the download speed. Slot Deposit Dana

How VPN Works

Generally, when we access a website on the internet, we will be connected to an ISP (Internet Service Provider). All data traffic requests for websites that we access will pass through the ISP server and can be seen by the ISP.

Unlike the case with computers that use a VPN when accessing the internet. VPN will encrypt data so that only VPN server users can find out user data traffic and sites opened by users.

Seeing how this VPN works, then:

  • ISP will not know the activity of VPN users on internet
  • Visible IP address is the VPN server IP
  • Using WiFi hotspots is safer
  • VPN providers can see the activity of VPN users on the internet

A few articles on the function and how this VPN works were made. With the many functions of a VPN, so that it you can used for positive things. Also suitable for beginners to get to know more about VPNs. Hope it is useful. IDNSlot Deposit Dana
