Meaning of network and its benefits

Basically, a network involves all of the components (hardware as well as software) linking computers across any type of distances. A network provides easy information access which increases the user’s productivity. Building up a network gives many advantages, but the 3 important facts are: File sharing – through which you can view, copy and modify files from your computer which stored on other computer. Resource Sharing – through which you can share resources such as fax machines, printers, CD Drives, FDD, HDD, Scanners, Webcam, Modem and more devices. Program sharing – as like file sharing you can share programs here on a network.

network1Types of Network Technology

Different Types of Network technology are:

LAN (Local Area Network) – it is using to connect close geographical area network devices, such as building’s particular floor, a campus environment or a whole building.

WAN (Wide Area Network) – it is using to connecting LANs together. Usually, it is used to connect LANs which are split by a large distance.

MAN (Metropolitan Area Network) – which is a hybrid among LAN and WAN.

SAN (Storage Area Network) – it provides high-speed infrastructure and facilitates for moving data among storage devices and file servers. Some of the advantages of SANs are: very fast performance, UP to 10 km’s distance span, due to centralization of data resources management is easy, it is available with redundancy features so availability is high and it uses thin type protocol which makes low overhead. SANs only disadvantage is, it cost little bit high.

CNs (Content Networks) – It is developed mainly for the ease users internet resources accessing. Normally, 2 different types of CNs were deployed by companies: downloaded Internet information catching and Internet traffic loads distribution across multiple servers.

Intranet – it is a local network which is mainly using by companies locally connects all their resources. It can also be say as, users inside the company can able to find their companies resources details without going outside the company. It includes LAN, WAN and MAN.

Extranet – it is an extended intranet, where internal services of a particular company are made accessible to a known external business partners or external users at remote locations.

Internet – it is using for accessing your network of internal resources by an unknown external users. For example, if you are having a website through which you are selling various products, with the help of internet external users can able to access your website to know concerning your service.

VPN (Virtual Private Network) – it is a secured network and a special type also. VPN is mainly using in internet for providing secure connection between the public network. It is also using in Extranet for providing secure connection among organization and its known external business partners or external users.
System Area Network – also termed as Cluster Area Network. In a cluster configuration, System Area Network links computers having high-performance and high-speed connections.

network2Wi-Fi (Wireless Local Area Network) – it can use to connect internet type of network resource through wireless network access point, where access point need to have 20 meters above indoor range and greater outdoor range. Wi-Fi can use many devices such as personal computers, smart phones, video-game consoles, tablet computers, digital cameras and digital audio players.

Complete Guide On How To Recover Data From SSDs – SSD Drive Data Recovery Service

Why recovery is essential?

Advancements in computer technology had crossed various huddles like recovering lost data from hard drives, etc. There are various situations where we might lose our important data from hard drives. These include the following: a) Drives may fail to boot, b) Drives may be encrypted with malware programs, c) Drives may be physically damaged enough in not connected to PC through cables, d) Drives may lose its function, etc.

ssd1Irrespective of anything that happens, still the data from these drives can easily be recovered. There are many reasons why we need to rely on recovering data from hard drives. For instance, if the company is engaged in storing confidential documents in these hard drives then if they are damaged then the data need to be restored. Software has been developed for automatically recovering the data from such drives.

In fact, there are many such software available in the market to recover data from hard drives. This is the reason why SSD drives are developed. Let us understand what SSD is first. SSDs are Solid State Drives used for storing data using memory chips for reading and writing data on them. Usage of memory chips in these SSDs help in accessing these hard drives much faster than any other hard drives. Also, these SSDs are not easily damaged physically as they are made in such a way they can tolerate physical vibrations, high temperatures, etc. This is how SSDs stand out from other hard drives. Irrespective of the file location within these hard drives, any files can be restored from these SSDs.

How can we recover data from SSDs?

Steps involved in SSD Drive data recovery service include the following:

• Among various software available for recovering data from SSDs and other hard drives, choose the right one fulfilling your demands including cost, feasibility and compatibility with your computer.

• After selecting the right software, try getting its original version. Always try to use only original version but not download the cracked version. Try installing the software in your computer, following all necessary steps thereby.

• Now try connecting your hard drives. For SSDs, choose the disk from where data needs to be recovered. Then, there should be options for scanning the disk which needs to be selected.

• If the scan fails to show all the data stored in SSDs, then you must select the option of Lost Disk Drives, which would enable scanning of lost data from SSDs.

• This final scanning would find the lost data from damaged SSDs. After viewing their thumbnails, choose whatever files you would require to recover from SSD.

• Then choose the recover option and select the right location where the recovered files need to be stored. This will be completing SSD Drive data recovery service more effectively.

Role Of Hard Drive And Its Size

The main responsibility of hard drive is storage of data’s. On your computer, everything you are saving is getting stored in hard drive. Not just pictures, documents, videos and music. Your preferences, your program files and your OS are storing on the hard drive of your computer. The sad truth is you will lose all the stored files if hard disk gets damaged.

drive hard1That’s why many people are maintaining backup system for storing their important files in that. In hard drive, everything which we have saved is measured in expressions of its size. Very smallest file is text, picture is little bit bigger, music is bigger than picture file and video is the biggest file. It acts just like a scale. Hard drive can’t know the difference between the files; it knows only the size of the files. Like things are measuring in kilograms, the files stored in hard disk are measuring as megabyte, gigabyte and terabyte. If you want to store or take a backup of minimum files, then smaller hard drive (such as 500GB) is enough. Rather, if you want to store or take a backup of more files such as lot of audio and video files, then you need to use larger hard drive (such as 1TB).

Connections and speed of hard drive

Connecting hard drive to your computer is having 4 basic ways: USB – it is the common connection type and no need to do any set-up; the computer automatically recognizes the drive once you plug-in and immediately you can able to save and read files. FireWire – it is like plug and play USB and most popular in transferring video files. SATA – it is the internal hard disk common connection which provides more speed in any format of highest file transfer. eSATA – it is less common and found in PCs with high-performance connection, connection of eSATA executes at speed that intimately looks like an internal drive.

When and how to recovery data from hard drive?

Necessary to recover data from hard disk is for many reasons such as: Read/write heads of hard drive’s damaging, due to mishandled or unprotected power surge hard drive becomes fail, if hard disk exposing to coffee, water, condensation, battery leakage, flood and so on, file allocation table missing or damaging, hard drive formatted inadvertent, accidental or incorrectly, Master file table is corrupted or missing, burnt away chips hard drive, corrupted or missing of files or folders, not recognizing of hard drive by BIOS, hard drive head gets crash and Boot sector not get recognized.

drive hard2Hard drive data recovery is of two types: one is logical and the other is physical. Logical failures are due to virus, malware programs, errors in programs or software, inadvertent deletion of data and lost partitions. Whatever be the cast, the lost data can be recovered resources and tools by a data recovery specialist. Physical failures are through accumulated or direct trauma, botched repairs, through tampering, accidental cause and so on. In this case, the data is safeguarded on the drive but due to physical damage of hard drive it difficult to get access to the device. For successful extract of your valuable data best equipment and technical skills required.
