Computer Network Timing Solutions
Jun 28th
Computer networks and the internet have dramatically changed the way we live our lives. Computers are now in constant communication with each other making possible transactions such as online shopping, seat reservation and even email.
However, all this is only possible thanks to accurate network timing and in particular the use of Network Time Protocol (NTP) used to ensure all machines on a network are running the same time.
Timing synchronization is crucial for computer networks. Computers use time in the form of timestamps as the only marker to separate two events, without synchronization computers have difficulty in establishing the order of events or indeed if an event has happened or not.
Failing to synchronize a network can have untold effects. Emails may arrive before they are sent (according to the computer’s clock), data may get lost or fail to store and worst-of-all, the entire network could be vulnerable to malicious users and even fraudsters.
Synchronization with NTP is relatively straight forward as most operating systems have a version of the time protocol already installed; however, choosing a timing reference to synchronize to is more challenging.
UTC (Coordinated Universal Time) is a global timescale governed by atomic clocks and is used by nearly all computer networks across the globe.
By synchronizing to UTC a computer network is essentially synchronizing the network time with ever other computer network in the world that uses UTC.
The internet has plenty of sources of UTC available but security issues with the firewall means the only safe method of receiving UTC is externally. Dedicated NTP time servers can do this using either long wave radio or GPS satellite transmissions.

Ten considerations when choosing a Computer Network Consultant.
In today’s increasingly complex computer age finding a great computer network consultant is imperative. The life of your business depends on it. Think about what would happen if your entire system were to crash. It could literally take years to regain all the client and product information you have worked so diligently to collect. How long would it take to get business running smoothly? “Ten considerations when choosing a computer network consultant” is a guide to selecting the right consultant in which to put your trust.
1. As with any project the first order of business is to lay out an organized plan. In order to maximize both yours and the consultant’s time, be sure to set written goals and expectations, and find a consultant who has the experience and knowledge to complete the project at hand.
2. Choose a consultant who will make the necessary time for face to face communications. This is most important at the beginning of the relationship. Much time and energy wasted can be avoided by sitting with the consultant initially for the amount of time necessary to make sure there are no misunderstandings.
3. She or he needs to be open to learning your organization’s systems, in order to make the most of its strengths and minimize its weaknesses. She or he should suggest a variety of options for improvements. Throwing the entire system out and starting over from scratch might be a quick easy way to approach your network but might not necessarily be the right solution. Find a consultant who is willing to do the work and provide you with several options.

Basic Part of Computer Hardware
Jun 23rd
If you are using a desktop computer, you may already know that there isn’t any single part known as a “computer”. A computer is a system of several parts working together. The physical parts which you could see and touch are jointly known as hardware. There are some computer hardware parts which collectively form a computer.
Computer Hardware Parts:
System Unit
The system unit is the heart of a computer system. Generally, it’s a rectangular box placed on or beneath your desk. There are several electronic components which process information inside this box. The most vital of these components is the central processing unit (CPU), or microprocessor, which acts as the brain of your computer.
Another component is the RAM or the random access memory which temporarily stores data that the CPU uses while the computer is on. When the computer is turned off, the information stored in RAM gets erased.
Hard Disk Drive
Your computer’s hard disk drive stores data on a hard disk, a firm plate or stack of plates with a magnetic surface. The hard disks normally serve as your computer’s primary means of storage, holding almost all of your programs and files as it can hold enormous amounts of information. The hard disk is usually located inside the system unit.
DVD and CD Drives
Almost all computers today come equipped with a DVD or CD drive, generally located on the front of the system unit.
CD drives use lasers to read or retrieve data from a CD and several CD drives could also write or record data onto CDs. DVD drives could do everything that CD drives can plus they can also read DVDs. If you have a DVD drive, you could watch movies on your computer. Several DVD drives could record data onto blank DVDs.
Computer Hardware and Terminology
Jun 17th
Computer is said to be the sum of its parts unlike other electronic devices. In case of a television, nobody cares about the make of a picture tube of a particular brand and its specifications. However, in case of computers, a knowledgeable consumer would first enquire about the specifications of its components such as motherboard, processor, hard disk, RAM etc., more than the brand name. Following is the computer hardware and terminology in a nutshell.
Several functions are included in a powerful chip known as a processor or microprocessor. Rolled into a chip, it’s the brain and heart of the computer. Its competence which is specified by its frequency and denoted using gigahertz depends on its speed of processing. It would function in a better way if the speed is higher. Also, there are numerous types of processors, including the 32 and 64 bit processor.
A yardstick of speed is not what bit rate is all about and the larger bit rate means that various computing processes can be performed efficiently by the processor at the same time.
Motherboard is another main item in computer hardware terminology. In other words, it’s the platform where all the other components are fitted in electrically. Over the years, several additional functionalities are slotted on to the motherboard such as graphics card, sound card and networking card. One should make sure that the motherboard is well-matched with other components such as RAM, hard disk and processor.
Computer hardware and terminology comprises of RAM and hard disk as its vital components. There are 2 types of memory in a computer. The memory stored on the hard disk is known as permanent memory and even when the computer is shut down it remains in the disk. On the other hand, once the computer is shut down RAM or random access memory will be off. Functional information while running a computer, like unsaved data and running programs are kept in this memory while the computer is on. The data is saved to the hard disk from RAM once you save a file.
