Computer Basics - Essay Example

A switch is closed, a piece of hardware receives a power on signal and starts its Job. Compare storage devices using four criteria: versatility, durability, speed, and capacity. To keep this answer basic, I will discuss the basic types of storage devices made available to us today. In the current year of 2015, we have “Solid State Drives” and “Hard Disk Drives”. With Head’s, you can achieve very high storage capacities, moderate durability, moderate speeds, and good versatility. Head’s are great for mobile PC’s and workstations that need to contain large amounts of data, while not needing the speeds of a SD.

Head’s have their faults of being fragile and slow read/write speeds, but can be almost as fast as a SD if purchasing a specific type of HAD. The other type of storage device is Sad’s or “Solid State Drives. ” Solid state drives use multiple AND Flash chips inside of it to hold memory. Sad’s are very compact, use no moving parts, but are limited by capacity and read/write cycles. Sad’s are commonly used in phones, smaller PC’s, USB flash drives, and small devices such as cameras and TV’s. Please explain the differences between RAM and ROOM. Where are RAM chips usually configured? Why are RAM chips considered to be volatile?

Before we begin to discuss this question, let’s form knowledge of what RAM and ROOM is. RAM is an acronym for “Random Access Memory’ which is Just as the name suggests, it’s a fast, random form of memory that is constantly being written to and read from. ROOM is also an acronym for “Read Only Memory’, Just like RAM, is self-explanatory being that it is memory that will only be read from, not written to. RAM modules are usually placed near the CPU because RAM is the “Waiting Room” for the CAP]. When something large needs to be processed, it is queued into the RAM to be fed into the CPU for efficient processing.

Think of it as being in your car. You need to get up to MPH, so you gradually accelerate. You cannot accelerate to 0-MPH in Just a fraction of a second, or you will more than likely experience extreme G-force and lose control of the vehicle. The same applies to a CAP]. A CPU cannot suddenly process a large file in one huge sweep, or you will experience a system failure and possible loss of data. RAM is there to slowly (and I say slowly loosely as there are millions of things processing in the midst of this) feed the CPU the information so it can efficiently process your information at a optimal speed.

Define storage mediums and storage devices. How are these different from one another? Provide at least three examples of both and elaborate on the purpose of each. Storage mediums and Storage devices are indeed, two separate objects that do different functions. A Storage Medium is something that simply holds data varying between a HAD to a stone slab. A Storage Device is something that reads the Storage Medium. This can be a record on a record player, the record being the medium and record player being the storage device. A HAD is a type of Storage Device that houses silicon magnetic platters, the Storage Medium.

The Platters house the actual information in magnetic sections, hills, and valleys. The HAD itself reads with a mechanized arm that goes back and forth over the Medium to translate to an electrical signal to be sent to the RAM for processing. A SD is another type of storage device that works in a similar way to a HAD. With a SD, rows of AND Flash chips are set up in rows and hold electrons in certain positions read as 1 or O. If you run electricity through these chips, you will instantly lose all data because the electrons will Just attract to the current.

A Storage Device is needed to regulate how his process is done safely in the form of a memory controller. The memory controller is given a signal to look for a file, the Storage Device then reads that location. When it understands where the file is, it is able to read from that particular section of the AND chip, the storage Medium. Alternative to HAD and SD DVD/CD/BLURRY. DVD’s are a type of Storage Medium that has pits that reflect a laser light that is produced via a DVD Reader. In this example the DVD is the Storage Medium is the DVD and the Storage Device is the DVD Reader. Have you ever experienced the blue screen of death (BSoD)?

If so, please describe hat happened and how you were able to fix the issue that caused the BSoD. If you have not yet experienced the BSoD, please explain in detail what this term means and provide suggestions about how to solve the problem. The scary BSoD, notorious for being the final blow to the Windows Operating System. O some, this marks the end of their computer, unable to be DB (Damaged Beyond Repair. ) What some mistake for a tragic situation, can sometimes be Just a easy 30 second fix in safe mode. A BSoD is given to the user when the hardware and software can’t properly communicate with one another and end up dividing by O.

Some common times you will see a BSoD is when new hardware is installed. When you have any type of hardware, you will always need a Driver to tell the hardware what the software is saying. When these two fail to communicate, it causes a backup f data, numbers start to no add correctly, the CPU becomes overloaded. A Kernel panic has Just happened. A simple fix for this is to enter Safe Mode, reinstall/install/repair drivers, reseat all connectors inside the computer, and restart. This is usually the best fix but in some cases, a clean install is needed. PART 2 My Computer Computer manufacture

Computer Model Envy Touch Smart Processor Manufacture Intel Processor Type Mobile 15 Processor Speed 2. GHz Operating System Windows 8. 1/ Debbie 7 RAM Capacity bib Windows Experience Index 6. 3 PART 3 [Disclaimer: All data speeds are representative of read speeds only] FLASH DRIVES Storage speeds are the entire main selling point of any memory component being it RAM, Head’s, or Sad’s. Storage speeds are the speeds at which a file can move from one Storage Device to another. Some things you may run across where storage speeds means a difference of $20 to $80 is Flash Drives, Thumb Drives, Jump Drives, etc..

With a well-known brand like Kingston. With Kingston Flash Drives, their lowest tier, budget drive is -?$10 dollars. This drive might offer numb/s. You can carry files up to the capacity of the drive easily but when moving larger files, may take longer than you normally would like. In the next tier, you will find these drives in a bit more durable casing, possibly with a cap. Inside these drives, you will find better manufactured memory chips and a better memory controller. These drives will usually offer two times the speed (-?numb/s) of the lowest tier drives, but will cost almost double, sitting at -?$20.

With today’s age of never ending evolution in technology, it is no surprise that a flash drive you bought in 2010 is now outdated. Today’s standard USB Flash Drive will include a new standard for USB memory drives called USB 3. 0. USB 3. 0 offers speeds up to numb/s for Just -?$9. This new standard give all devices with the standard huge boosts in read/write speeds so that you won’t have the hassle of adding or removing internal components to share files. HARD DRIVES/SOLID STATE DRIVES Hard drives/Solid state drives have come a long way from the age of owning a 40 ton Alison platter to hold a mere NUMB of data.

With this evolution from truck size storage to something Just bigger than your pinky, the speeds have increased with it as well. We all remember the days where you had to dial in to AOL, wait forever, then try and find your website that took 30 or more seconds to load, but now we can have a website instantly after we hit enter. Hard Drives/Solid State Drives are no excepting to this. With the ever growing need to hold information, move it quickly and write back to a drive has launched a enormous effort to make speeds faster than what they ere 4 years ago.

Even back in Just 2005, we have very inefficient memory controllers, slow moving platters (only applicable to Head’s), and very large power consuming cases that housed these drives. In 2010 when Sad’s became available to consumers at a reasonable price, they were also very inefficient and power consuming. Factors that help propel these speeds included faster moving motors from RAMPS to a whopping RAMPS being the standard. More efficient and smarter memory controllers to translate quickly and send the information to where it needs to go has also helped in this factor.

The biggest factor in storage speeds increasing would be the interface that Storage Devices used. In 2000, Head’s where interfaced with a standard called PAT (PArallel ATtachment) and DID(eliminated Drive Electronics). This interface was slow in took very large amounts of time to move data along each of the 15 out of 40 pins. After sometime, a new standard was introduced, SAT. STATS (SAT @ KGB/S) today’s standard, succeeding SAT 3 (SAT @ KGB/s). With this new revision, a more reduced cable was also introduced. This allowed for smaller drives, faster speeds and more compact storage solutions.

PRINTERS Printers come in 2 many shapes, sizes, and do many different Jobs. When walking into a store or shopping online, you find yourself asking “Why is one printer $80 and the other $399? ” Some questions you should ask yourself is: How much am I printing? How often will I print? Am I printing in color or black and white? Will I need to print from a network When asking “How much you will print”, you need to keep in mind that if you are printing at least a hundred pages daily, you will be considered using your printer heavily.

If you fall into this category, a Laser/Toner printer is ideal for you because it an fuse ink quickly and has a very quick response time, response time being the time from hitting “print” to actually printing. A Laser/Toner can quickly print at close to 30 pages a minute, where as a normal ink printer would be at 5-9 pages a minute. Asking yourself “How often will I print” is a huge factor when shopping for a printer. The main difference between a toner cartridge and a ink cartridge is that toner is dry and ink is wet. With ink being wet, it has a short shelf life because it will dry out after so long.

Toner is already dry and has a huge shelf life equal to paper. While you as “Will I be printing in color or Just black and white”, you will notice that only some printers say photo paper compatible. You will only find this feature on ink printers. While some laser printers do print in color, it isn’t in a very sharp image. Asking yourself “Do I need to print from a network” is also a huge factor in buying a printer. Some printers only print via USB or only via a network. Make sure you watch for the interface the printer offers because you don’t want to buy a printer that is only USB and you have no room in your office to place it.
