What is the Difference Between Firmware and Hardware?
Sep 5th
Let us take a look at what ‘Hardware’ means when you talk about computers – almost all of the devices that you can find assembled into your computer come under the category of hardware. This includes the processor, the memory, the motherboard, the hard disks, the removable media drives (CD-ROM/DVD Reader/Writer, floppy drives, USB drives, the power supply, sound card, networking devices and Input/Output devices.
What makes all these hardware devices work together is the software that controls them. Software is the term given to programs that are usually run on computers. You may be familiar with and may have used many software packages – word processing software such as MS-Word and games are common examples. Software normally resides on the hard disk of the computer and is usually invoked by the operating system to perform specific tasks. It is usually coded in high-level languages like C or Java.
Firmware is a term used for a specific type of software. Many processors (other than the CPU of your computer) require software to implement a functionality and this usually is programmed into some kind of Read-only Memory (ROM) on the device itself. This bundled or embedded software that controls a hardware device is called Firmware. Firmware is code that is meant for a particular hardware device and is usually in machine code (patterns of zeros and ones).
Home Computer Repair – Do It Yourself?
Sep 2nd
Home computer repair is not brain surgery! Most computer repairs can be broken down into two specific areas, software and hardware. Now I do admit that in some people’s hand, a screwdriver can be a dangerous object. But if you can change a light bulb without shocking yourself, I’d bet you could swap out a computer part. Software gets a little trickier but is still within the grasp of most computer users.
I’ve been involved in computer repair in one way or another for over 25 years. The three major repairs I get called for on a weekly basis are:
Spyware/Malware Issues
Hardware failure (power supplies, hard drives, and ram usually)
Computer boot problems (lost password, toasted OS, hardware failure)
All of these can be quite a challenge depending on the value and risk of losing important data, which can be anything from tax records to photos. Any computer can be repaired; it just depends on time and budget. But not all data can be rescued. If a hard drive suffers a catastrophic hardware failure, data recovery is doubtful (unless you want spend 100’s if not 1000’s of dollars for special services).
The Meaning and Nature of Comprehensive Business Networking and Hardware Solutions
Aug 30th
Hardware is the term given to the computer machinery and the various individual pieces of the computer. Hardware must be loaded with corresponding software to make a computer system perform meaningfully and thus produce useful output. In all, both hardware and software must work together.
If you find some problem with the computer components, you look for hardware solutions. There are many companies who take up Annual Maintenance Contracts (AMC) from the customers and provide them complete business networking and hardware solutions, comprising of hardware solutions, network installation service and network security & support service in lieu. These companies have their own trained teams of engineers in both the software and hardware fields.
Many online websites and PC manufacturing companies are also providing comprehensive business networking and hardware solutions in their questionnaire. They are providing on-site support to their customers by their sending representative to the site to diagnose, monitor and solve any hardware/ software/ network problems with the most suitable feasible long-lasting solution(s).
10 Top Reasons Why I Have to Upgrade My Computer
Aug 27th
The rate at which technology is improving is very fast and in the time you get comfortable with the computer hardware you have bought, several new and improved models appear in the market. While some people prefer to keep their computers state of the art, most of us have a ‘If it isn’t broken, don’t fix it’ attitude when it comes to upgrading or replacing our computers.
This is a strategy that could prove expensive in the long run. It is always better to upgrade your computer on a regular basis, especially if you have had it for over 2-3 years. Even if your computer has had a largely trouble-free existence, you really need to consider periodic upgrades and here are the reasons why you must dos so:
1. Increase in Processing Speed – This is one place where you really get to notice an improvement in performance. If you are upgrading from a Celeron 433MHz processor to a Pentium 4 1.6GHz, you would really notice the difference in performance!
2. Faster Memory Access – Improvements in CPU speed are usually accompanied by improvements in the speed at which data transfer occurs between the CPU and RAM. This is another area that provides an improvement in performance.
Computer Repair – Is It Hardware, Software Or Both?
Aug 24th
Computer repairs can involve hardware repair, software repair, a combination of both, and or probably some troubleshooting. It\’s not for the faint of heart; if you are pulling your hair out, you may want to consider doing something else about it like, call the Geek Squad. Basically what we are attempting to get our machine to load properly. When a PC starts up, first it tests all the connected hardware and then looks for the software that it needs to load in order to run properly. If the machine does not power up, or the machine powers up, but does not load, then we have a pretty good idea as to what the problem may be.
All of the parts of your computer that you can physically see and touch it is your hardware. It takes quite a bit of well engineering and design for all those components must work together well. Sometimes components can be damaged by external forces. To clarify external forces can mean a few things. Shock damage or the effect of being dropped can certainly cause damage to a component therefore rendering it inoperative. Also I would like to include a power surge, over voltage, over temperature, under temperature, water emersion, excessive moisture, acts of nature, etc external forces which can cause failure of a component.
