A depth of Understanding

Once upon a time, in the 1830s, before the electric lightbulb or the telegraph was invented, the first programmable computer was designed by Charles Babbage and Ada Lovelace in Cambridge, England.

To put things in perspective, Babbage and Lovelace's advancement of human technology was made concurrently with America’s Wild West Pioneers, the Adventures of Davey Crocket, and the Battle of the Alamo.

Regarded as the first computer programs or software ever developed, the initial purpose of their analytical engine was to produce more accurate astronomical and nautical charts. The early computers of Alan Turing and Bletchley Park filled a room. These earlier machines built by Babbage filled a warehouse.

The basic logic and design of Babbage’s machine is still at the heart of every computer today, although much smaller than the towers of cogs and pistons he constructed. We are still building on top of those same rudimentary concepts when we create software today. In a modern computer, instructions are sent to a central processing unit (CPU) using electrical voltage instead of punchcards, but the result is essentially the same. With these basic mathematical instructions it is possible to build commands and receive output. Languages can be written to manipulate those commands, and from them an operating system can be built. With this semantic programming language, a programmer can create and share libraries of functions and scripts. Using these libraries, they can write programs to run on the operating system. That’s how computers grew from mechanical levers and wheels to MS Office, Call of Duty, or Instagram: layers and layers of coded libraries and languages.

You don’t need to know all of this to take a picture on your phone and share it with the world, or to make a spreadsheet, or play a video game. But we at CTI do understand the interaction between these levels of code and logic. That is why we are often able to sit down in front of a program we’ve never used before and start using it instantly. It’s how we can begin to diagnose a problem without even looking at the machine. We understand software. We use it, configure it, manipulate it, and build it. Whatever your software needs are, we can come up with a plan to get your system running smoothly.
