Computer Software is May be Viewed as the Language of Computers
Sep 5th
Software, on a broader perspective, refers to any electronic media content. The term computer software is a term used to refer to computer programs, procedures, and documentation that perform specific tasks on a computer system.
For more details go to: www.pure-profit-software.com This term is also used to describe application software or productivity software, system software such as computer operating systems, and middleware – software that manages and coordinates distributed systems.
Computer software is may be viewed as the language of computers. There is a wide variety of software available and these are categorized into three different types: system software, application software, and programming software.
System software runs the computer system including all the hardware devices contained within the system. This software is used by the computer to interpret input from external sources into something a machine can understand. Software works with the computer’s hardware components and includes the computer’s operating system, diagnostic tools, device drivers, utilities and more. One may automatically think of computer operating systems when the words software system is mentioned – operating systems run the computer. The most popular operating systems today are those manufactured by Microsoft. Other competing operating systems are open source OS such as Linux and UNIX.
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).
Connected Via Computer Network
Aug 30th
Most of us remain ignorant over how a computer works. We simply just turn on the computer and connect to the internet to access various websites. However, have you ever wondered how we can log on to the internet?
Basically, you are connected by a computer network which is divided into two major categories. They are the client/server network and peer-to-peer network. In the client/server network, there is a computer which plays the major role known as server whereby all the files, data in the form of web pages, documents or spread sheets files, videos, database and resources are kept. Other computers which get information and data from the server are therefore known as client. Hence the term client/server network whereas in the peer-to-peer network, all the computers play equal roles because no computer act as the centralized server.
In a computer network, there is something called a network topology which describes the structure or layout of a network. Some of the network topologies are described as the star, bus, ring and mesh structure. For example in the star topology, all the computers in the network are connected by a centralized device such as hub or switch which form a ‘star structure.’ However if one of the hubs fails to function, then the computers within the network will lose their connectivity and communication.
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.
