![]() ![]() ![]() The Small Magellanic Cloud is only about 19 light years in its diameter. The Large Magellanic Cloud is about 38400 light-years in diameter and it is visible with the naked eye when seen from the Southern Hemisphere. The Large and the Small Magellanic Clouds are just two of the four Irregular galaxies that can be found in the Local Group from where the Milky Way galaxy also belongs. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe. The Magellanic Clouds are the nearest neighbors of the Milky Way in the Space. The following is a list of notable galaxies. Some Elliptical galaxies are found to be small while other Elliptical galaxies are very large. The Elliptical galaxies that are flattened are designated as E7 galaxies. The majority of known galaxies that fit in this. The Elliptical galaxies that are less spherical are designated as E3 galaxies. Over the past few years, astronomers have increasingly discovered that galaxies seem to come in three main shapes: Elliptical, irregular and spiral. The Elliptical galaxies that are almost spherical are designated as E0 galaxies. all galaxies are either prolate, triaxial or oblate), they found that both spiral and elliptical distributions are. From elliptical shape, they range from almost spherical to a flattened disk-like shape. The Elliptical galaxy is considered as the most common type of galaxy. Sba, SBb and SBc are used to classify the galaxies with arms that extend from a bar of stars in the nucleus they are called as “barred” spirals some other galaxies are designated as S0 they are Spiral galaxies which have no arms. ![]() Some Spiral galaxies are classified in accordance to how open their arms these classifications are S2, Sb and Sc. Spitzer Telescope Galaxies of All Shapes and Sizes This artist's concept illustrates the two types of spiral galaxies that populate our universe: those with plump middles, or central bulges (upper left), and those without them (foreground). In here, several arms may come out consisting of dust and stars. In Spiral galaxies, there are bulges or nucleus and There are different shapes of galaxies in this group some galaxies are irregular, others are spiral while the others are elliptical. Our galaxy, the Milky Way is within the cluster of galaxies named as the Local Group. Galaxies are different in their shape and appearance some galaxies are Spiral, the others are elliptical and the others are irregulars. The scientist and astronomers had classified the galaxies in the universe in accordance to their appearance and shape. In the Southern Hemisphere, it passes through the Cassiopeia constellations and Cygnus constellations while in the Northern Hemisphere it passes through the Southern Cross constellation and Scorpio constellation. The brightest part of the Milky Way galaxy lies in the constellation of Sagittarius. This galaxy has an estimated 200 billion stars including the sun. The solar system consists of our sun and the nine planets including the Earth belong to the Milky Way galaxy. ![]() ![]() ![]() Her teaching focuses on global environmental issues, climate and development, and on Latin America.

The combinations are really endless and can make for a great collectible experience. The most popular color used in vinyl records color is still black but there are some really awesome color combinations you can get like this Rastafarian themed vinyl or this rainbow colored vinyl. Polyvinyl Chloride in its natural state is clear, which allows for all kinds of great color combinations and choices. If Polyvinyl Chloride sounds familiar that is because it is the same thing some plumbing pipes are made of called PVC pipes! ![]() Which is produced from crude oil and chlorine. The plastic used for producing a record is polyvinyl chloride. As we have covered in the past, in recent years vinyl records have made a huge comeback. This record technology through time went to the wayside thanks to cds but never went fully away. These used to be how you listened to music at home. These are also commonly called vinyl, albums, or records. When the stylus (or needle as some people newer to the hobby call it) from a turntable is applied to the groove of the vinyl while spinning your record it produces vibrations that turn into sound. Vinyl records are discs made from heated polyvinyl chloride that has been pressed from a master disc, thin with grooves to produce sounds. This vinyl was used to create the modern-day record you see now! What Are Vinyl Records? When the 1940s came around, the introduction of polyvinyl chloride hit the market. Through the times, the sizes of the discs changed to accommodate longer lengths on the albums. When comparing the gramophone to Edison’s phonograph the sound was lacking though through time the quality in manufacturing got better resulting in better recording and sound quality as well. These discs were commonly made from shellac. Emile’s system setup was called a gramophone and was hand-cranked with a large horn on top. Recordings on a flat disc did not come until 1889, invented by Emile Berliner. ![]() Fast forward to 1880 when Thomas Edison upgraded his cylinder to hollow wax instead of the foil and basically, the recording and recorded sound market was created. In the early stages, Thomas Edison used wax impregnated paper and tinfoil in recording. This device however did not play discs like what you and I are used to in a record, but cylinders. The original concept of sound being recorded and played back to you can be dated back to 1877 with a device called the phonograph invented by Thomas Edison.

That said, would gamers want more of this Saints Row? If Saints Row's 2022 reboot fails to meet expectations, it will make Deep Silver Volition and their overlords less likely to invest in another new Saints Row title. The sad thing about Saints Row's reboot is that it may have killed off the franchise. Many reviewers have told gamers to wait for sales or an eventual Game Pass or PlayStation Plus release, seeing the game as unworthy of most people's time given its current state and current pricing. There is fun to he had in Saints Row, but gamers are best off waiting for patches to squash this game's bugs, or discounts that will make the game's pricing seem worthwhile. There's a reason why this game has several 4/10 review scores. Its story and characters can be hit and miss, but the experience is carried by fun gameplay and an endearingly dumb sense of humour. The game no longer pokes fun at other AAA titles with parody missions or witty one-liners, and in many senses Saints Row's 2022 reboot is inferior to prior Saints Row games. While it is unknown how consumers will react to Saints Row's reboot, many critics have heavily criticised the game's pre-launch bugs, frequent pop-in issues, and the game's abandonment of expected Saints Row traits. Overall, the game has a "Fair" rating on OpenCritic with a Top Critic average score of 67 out of 100.

It needs to be durable, brutal, and heavy-hitting, and because we like a little style when slaying zombies, it needs to cool look. To be considered the best weapon, it needs to have more than stopping power. What good is a golden AK-47 with a 30-round clip when there are 31 zombies out there?

Another issue was that the POS system needed to be online for data exchange, email and web ordering. The problem was that his POS application developer went out of business and there was no option to migrate to another version of Windows and the evaluation of a new system will take too long. Of course he knew that Windows XP not supported for the general public anymore and many applications (including his antivirus) were end of life too. ScenarioĪ close friend of mine came to me with an inquiry, he told me that he was using a POS solution that runs on a Windows XP installation. In our test scenario we’ll take a real case that we’ve came across lately. In this case we’ll take a much more pragmatic approach that may be used as a single solution in a small environment or as a security control in a greater environment.

Most flash drives use a standard type-A USB connection allowing connection with a port on a personal computer, but drives for other interfaces also exist (e.g. The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected. Some are equipped with an I/O indication LED that lights up or blinks upon access. USB drives with USB 2.0 support can store more data and transfer faster than much larger optical disc drives like CD-RW or DVD-RW drives and can be read by many other systems such as the Xbox One, PlayStation 4, DVD players, automobile entertainment systems, and in a number of handheld devices such as smartphones and tablet computers, though the electronically similar SD card is better suited for those devices, due to their standardized form factor, which allows it to be housed inside a device without protruding.Ī flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic, metal, or rubberized case, which can be carried in a pocket or on a key chain, for example. ![]() USB flash drives use the USB mass storage device class standard, supported natively by modern operating systems such as Windows, Linux, macOS and other Unix-like systems, as well as many BIOS boot ROMs. Until about 2005, most desktop and laptop computers were supplied with floppy disk drives in addition to USB ports, but floppy disk drives became obsolete after widespread adoption of USB ports and the larger USB drive capacity compared to the "1.44 megabyte" (1440 kilobyte) 3.5-inch floppy disk. The ability to retain data is affected by the controller's firmware, internal data redundancy, and error correction algorithms. However, as with any flash storage, data loss from bit leaking due to prolonged lack of electrical power and the possibility of spontaneous controller failure due to poor manufacturing could make it unsuitable for long-term archival of data. Additionally, they are less vulnerable to electromagnetic interference than floppy disks, and are unharmed by surface scratches (unlike CDs). ![]() Compared with floppy disks or CDs, they are smaller, faster, have significantly more capacity, and are more durable due to a lack of moving parts. Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to physically last between 10 and 100 years under normal circumstances ( shelf storage time ).Ĭommon uses of USB flash drives are for storage, supplementary back-ups, and transferring of computer files. As of 2018, 2 TB flash drives were the largest available in terms of storage capacity. As of March 2016, flash drives with anywhere from 8 to 256 gigabytes (GB ) were frequently sold, while 512 GB and 1 terabyte (TB ) units were less frequent. Since first appearing on the market in late 2000, as with virtually all other computer memory devices, storage capacities have risen while prices have dropped. It is typically removable, rewritable and much smaller than an optical disc.
